The subgenus Cryptops may be divided into those species with, and those without, an anterior transverse suture on tergite 1. The latter group may be further separated intospecies with the ultimate leg femur without a saw tooth or teeth (here termed the hortensis group) and those with one or more (here termed the doriae group).The species of the Old World of the hortensis group are the subject of this paper. Where possible, the non-European type material has been examined and data for European species added from the literature. Cryptops omissus Ribaut, 1915 (Kenya), Cryptops mirus Chamberlin, 1920 (Tahiti) and Cryptops arapuni Archey, 1922 (New Zealand), lacking ultimate legs cannot be assigned to either the hortensis or the doriae group. Cryptops inermipes Pocock, 1888, which lacks saw teeth on the ultimate legs is considered here. Cryptops nanus Attems, 1938 (Hawaii), Cryptops navis Chamberlin, 1930 (Singapore), Cryptops philammus Attems, 1928 (Southern Africa), Cryptops sinesicus Chamberlin, 1940 (China), Cryptops stupendus Attems, 1928 (South Africa) and Cryptops tahitianus Chamberlin, 1920 (Tahiti) appear from their descriptions to belong to the hortensis group but have a prefemoral saw tooth or teeth and thus belong to the doriae group.
The following species are regarded as valid: Cryptops covertus Chamberlin, 1951, Cryptops daszaki Lewis, 2002, Cryptops decoratus Lawrence, 1960, Cryptops hortensis (Donovan, 1810), Cryptops inermipes Pocock, 1888, Cryptops lobatus Verhoeff, 1931, Cryptops mauritianus Verhoeff, 1937, Cryptops melanotypus Chamberlin, 1941, Cryptops nigropictus Takakuwa, 1936, Cryptops parisi Brolemann, 1920, Cryptops songi Song et al., 2010 and Cryptops stabilis Chamberlin, 1944. Examination of further material is required to establish the true status of Cryptops brignolii Matic, 1977, currently regarded as valid. Cryptops hortensis atlantis Pocock, 1891 is returned to full specific status as Cryptops atlantis.
Cryptops basilewskyi Matic & Darabantu, 1977, Cryptops kalobensis Goffinet, 1971 and Cryptops niloticus Lewis, 1967 are junior subjective synonyms of Cryptops nigropictus. Cryptops penicillatus Lawrence, 1960 is a junior subjective synonym of Cryptops decoratus and Cryptops decoratus sensu Lewis (from Mauritius and Seychelles) is a junior subjective synonym of Cryptops melanotypus. Cryptops parisi cottarellii Matic, 1977, and Cryptops parisi rhenanus Verhoeff, 1931 are junior subjective synonyms of Cryptops parisi. Cryptops campestris Attems, 1953, Cryptops compositus Chamberlin, 1952, Cryptops medius Verhoeff, 1901, Cryptops orthus Chamberlin, 1951, Cryptops parisi sebini Verhoeff, 1934 and Cryptops philammus gabonensis Demange, 1968 are regarded as nomina dubia.
A key is provided to the fourteen species considered valid. However, the status of four of them, namely Cryptops nigropictus, Cryptops decoratus , Cryptops melanotypus and Cryptops songi, which are very similar, and the species that have been here synonymised with them, is uncertain. More material and more refined techniques are required to ascertain their exact status. Whatever that is, however, there can be little doubt that we are dealing with some closely related and very widely distributed populations. This suggests that Cryptops species are easily dispersed over large distances.
Chilopoda, Cryptops hortensis, group, Old World, review, key
The subgenus Cryptops (Cryptops) Leach 1815 may be conveniently divided into those species with, and those without, an anterior transverse suture on tergite 1. The latter group may be further separated intospecies with the ultimate leg femur without a saw tooth or teeth (here termed the hortensis group) and those with one or more (here termed the doriae group). This subdivision may well not be a natural one but is convenient for the present, bearing in mind the parlous state of Cryptops taxonomy.
The hortensis group of Cryptops is the subject of the present paper. It is characterised by a cephalic plate without complete paramedian sutures and generally overlapped by tergite 1, tergite 1 without sutures, and no saw teeth on the femur of the ultimate leg. Cryptops inermipes Pocock, 1888, characterised by the complete lack of saw teeth on the ultimate legs, is also considered here.
Cryptops (C.) zelandicus Chamberlin, 1920, which would appear from the description to belong to the hortensis group, was synonymised under Cryptops spinipes Pocock, 1891 by
The following species: Cryptops omissus Ribaut, 1915 (Kenya), Cryptops mirus Chamberlin, 1920 (Tahiti) and Cryptops arapuni Archey, 1922 (New Zealand), have no anterior transverse suture on tergite 1 but cannot be assigned to either the hortensis or the doriae groups as they lack ultimate legs.
Some species that would appear from their descriptions to belong to the hortensis group in fact have a prefemoral saw tooth or teeth and thus belong to the doriae group. They are: Cryptops nanus Attems, 1938 (Hawaii) (
Specimens were studied by light microscopy using an eyepiece graticule to make drawings onto squared paper calibrated for different magnifications using a stage micrometer. They were examined by reflected light in the preservative (70 or 80% ethanol) and sometimes blotted off briefly to observe surface features such as sulci. They were cleared in 2-phenoxyethanol which was also used as mounting medium for temporary mounts.
The Old World in the title of this paper is taken to mean
the Palaearctic, Afrotropic, Afrotemperate and Oriental regions as

The type material of Cryptops basilewskyi was described from Prosperous Bay, St Helena by
Maximum length 18 mm (14 mm). Colour: cephalic plate light orange, trunk light yellow with dark grey or black pigment on either side of heart and a narrow lateral strip on tergites 3–20, very little on 2 and 21. Pigmented areas also ventrally on 2–6 (Matic & Darabantu, fig.142 a, b, c).
Two basal articles of antenna with long and medium setae changing through 3 and 4 to dense short setae with basal whorl of medium setae on 5. Cephalic plate almost circular the posterior margin covered by tergite 1 (Fig. 1) (not covered by T1). Two very short anterior oblique sutures and short posterior paramedian sutures seen in one specimen only (anterior and posterior sutures present). Clypeus with 2 post-antennal setae, 3 in mid region except for 1615/V where there are 4. Prelabral setae 6. Specimen 6269/V with 2 post-antennal and 5 intermediate setae (Fig. 2).
Forcipular coxosternite very slightly curved on each side with 2 or 3 long to moderate setae (3+3), the innermost slightly further from the edge, and several small setae just behind anterior margin on each side (Fig. 3). Poison gland calyx subspherical situated in anterior region of trochanteroprefemur.
Tergite 1 without sulci, T2 with weak paramedian sulci occupying posterior third to half of tergite, complete 3 or 4 to 20. Lateral crescentic sulci on 3 to 19 or 20. Paramedian sutures could not be seen clearly in cleared specimens. Sternites with median longitudinal sulcus from 2 to 19. Weak transverse sulci 2 to 19 or 20 (only a slightly curved transverse sulcus). Sternite 21 wider than long, posterior margin curved (Fig. 4).
Pore field occupying anterior 54 to 57% of coxopleuron, with 12 or 13 pores (5 to 6 in each field). Three to 6 minute setae in pore field in the 2 largest specimens (no setae), 5 to 6 posterior to the pore field and 5 to 8 on the posterior edge (Figs 4, 5).
Ultimate legs with fine setae except ventrally and posteriorly on the prefemur and ventrally on the femur where they are thicker. Without tubercles or spinous processes. Tibial saw teeth 6 or 8, tarsal 3 (6+4). Tarsal claw without pretarsal accessory spurs.
Legs 1 to 19 with fine setae and tarsus very weakly divided or not (uniarticulate in holotype, biarticulate in paratypes). With a single accessory spur about half length of claw (Fig. 6).
Cryptops basilewskyi has only been recorded from St Helena. It is very similar to Cryptops nigropictus Takakuwa, 1936 from Taiwan and the Ryuku Islands apart from the apparently the faint central longitudinal sulcus on tergites 1 and 2 in the latter. This I regard as trivial character and consider Cryptops basilewskyi to be a junior subjective synonym of Cryptops nigropictus (see p. 35).

Chamberlin’s description of the arrangement of saw teeth on the ultimate legs differs markedly from that of the lectotype which otherwise compares well with his brief description. Further material is required to resolve this difference.

Madagascar.
Cryptops penicillatus (from Madagascar Centre and Madagascar Sambirano) is very similar to Cryptops decoratus (from Madagascar Sambirano, Madagascar Nord and Madagascar Est). These are distinguished in Lawrence’s (1960) key as follows:
– | Colour uniform yellow: transverse sulci of sternites stronger than the longitudinal sulci | Cryptops penicillatus |
– | Greenish black pattern on dorsal surface and sometimes also on the pleural and sternites; longitudinal sulci of sternites clearly more marked than the transverse sulci | Cryptops decoratus |
His key, however, does not tally with the text which states that Cryptops penicillatus is without transverse sulci on the sternites and Cryptops decoratus the transverse sulci are weak. These do not tally with my observations on the two holotypes which both have a broad longitudinal and a narrow transverse sulcus and thus do not differentiate the species. I regard the two as conspecific Cryptops penicillatus being a Cryptops decoratus lacking dark subcutaneous pigment.

(The latter in parentheses where appropriate).
Length: 10–15 (7.5–14) mm. With dark subcuticular pigment, though very
little in specimens from Serpent Island as compared to those from Round
Island (only 5 of 15 specimens from the Seychelles had black or grey
subcuticular pigmentation the remainder showed no dark colouration).
Cephalic plate and T1 without sutures. Clypeus with 2+1+2+6 (Fig. 34)
or 2+1+2+2+6 setae. Anterior margin of forcipular coxosternite slightly
curved on each side with 2+2 or 2+3 or 3+3 long submarginal setae (Fig. 31) (2+2). Poison gland calyx subspherical, situated in anterior region of forcipular trochanteroprefemur (Fig. 32). Posterior margin of sternite 21 straight or slightly curved (mostly with rounded posterior margin, rarely straight) (Fig. 35).
Pore field occupying anterior 60–70% of coxopleuron, with 7–16 pores
(8–14), 5–8 small setae in the pore field (4–6) and 1–3(4) between it
and the coxopleural margin ((0)1–2) (Fig. 36). Ultimate leg prefemora with broad medial longitudinal glabrous area with 5–7 tibial and 3–4 tarsal saw teeth (Fig. 37).
Pretarsal accessory spurs of legs 1–20, the posterior 40% length of pretarsus the anterior slightly shorter but sometimes only 12% of the pretarsal length (Fig. 33). The accessory spurs short in Seychelles material, the second very short and easily overlooked (Fig. 38).
The specimens from Mauritius and the Seychelles may be differentiated from Madagascan Cryptops decoratus by the possession of the glabrous area on the ultimate prefemur and lower number of setae posterior to the coxopleural pore fields. These differences are relatively minor but consistent. They are clearly very closely related to Cryptops melanotypus Chamberlin, 1921 and are here regarded as belonging to that species although it is known only from a single specimen (see p. 3).

The differences in the number and type of the saw teeth between Cryptops hortensis atlantis and Cryptops hortensis are major and I consider them more than sufficient to return Cryptops atlantis to full specific status. It is worth noting that

Length 27 mm.Without dark subcutaneous pigment. Cephalic plate without sutures. Anterior margin of forcipular coxosternite barely protuberant, with three or four fine submarginal setae on each side on the anterior margin. Poison gland calyx ovoid, situated mainly in the anterior part of the trochanteroprefemur. Posterior margin of sternite 21 slightly curved.

Length 27 mm. Colour: brownish orange, cephalic plate brown. Antennal articles 16 [d]+16 [d], very long. Article 10 twice as long as wide (Fig. 55) with an irregular whorl of long basal setae (Fig. 56).
Cephalic plate without sutures, overlain by first tergite. Forcipular coxosternite slightly convex on each side with 4+3 fine submarginal setae (Fig. 57). Calyx of forcipular poison gland ovoid and situated in the anterior part of the trochanteroprefemur (Figs 58, 59).
Paramedian and crescentic sulci clearly visible from tergite 3 (second [tergite] with two shallow sulci; the rest, with the exception of the last, bearing four sulci). Sternite sulci not seen but the transverse apodeme is clear (each, the first excepted, with a median longitudinal sulcus, and most of them with a median transverse sulcus, the distinctness of this latter sulcus is variable, and it almost disappears in the posterior region of the body).
Sternite 21 with sides converging posteriorly with a slightly convex posterior margin (Fig. 60). Coxopleuron with about 70 pores and occupying approximately anterior 75% of the pore field. With two setae in the pore field, one behind and 6 on the posterior margin.
Ultimate legs now missing (denticles absent upon the under surface of the tibial and proximal tarsal segments of the anal legs). Twentieth pair of legs now missing. Ambulatory legs (Fig. 61) with undivided tarsi (legs, all that remain, remarkably hirsute but none of the segments spiny.). Pretarsal accessory spurs minute (Fig. 62).
Christmas Island (Indian Ocean).
The lack of saw teeth on the ultimate legs would
appear to be an extremely rare mutation. The condition has not been
reported from any other species in the genus. Unfortunately the fact
that the ultimate legs are now missing does not allow confirmation of
the condition. It is possible that

Anterior margin of forcipular coxosternite slightly curved on each side, with 2 long and 2 very short submarginal setae on right and 2 long and 3 very short on left. Those on left appear mostly marginal probably due to distortion (Fig. 71).
Tergites with incomplete median ridge from 7–17, lateral crescentic sulci from 3, incomplete paramedian sulci from 6 but these latter very difficult to determine as the cuticle is wrinkled longitudinally as seen in specimens in early stages of ecdysis (first and subsequent tergites bisulcate, the sulci mostly complete). Traces of paramedian sutures seen only on tergite 10 and 15 in the cleared specimen. Sternite cruciform sulci not observed. Sternite 21 with broadly rounded posterior corners, posterior margin straight.
Coxopleuron with 17 pores, 6 beneath the margin of sternite 21, the pore field occupying the anterior 60% of coxopleuron and without setae. Two setae between pore field and posterior margin on which there are 5 setae. Ultimate legs (loose) with long fine setae, a longitudinal glabrous area medially on prefemur.

Philippines, Mauritius, Seychelles.
The holotype is small and delicate, nevertheless most characters are visible. The absence of minute setae from the coxopleural pore field may be a juvenile character. It has a relatively high number of coxal pores and ultimate leg saw teeth for such a small specimen. With the current state of our knowledge it is, however, not possible to separate it from the “Cryptops decoratus” populations from Mauritius and the Seychelles, described above, which I regard as conspecific with it and hence junior subjective synonyms.

The data available are insufficient for the exact identity of Cryptops parisi gabonensis to be determined. It is here regarded as a nomen dubium. As noted in the introduction, Cryptops philammus has a saw tooth on the ultimate leg femur and thus belongs to the doriae group of species.

The separation of those Cryptops s. str. species lacking an anterior transverse suture on tergite 1 into two groups dependant on the presence (doriae group) or absence (hortensis group) of a saw tooth or teeth on the ultimate femur may prove to be artificial but is adopted as a convenient way of dealing with of this group of species pro tem. The character has been overlooked by some workers in the past and species that appear from their description to belong the hortensis group in fact belong to the doriae group (see Introduction). Evidence to suggest that this separation may, however, be a natural one, is provided by the fact that no species in the doriae group have been recorded from Europe and no members of the hortensis group have been recorded as naturally occurring in Australasia or the Afrotemperate region.
Ten of the species keyed out here are quite distinct. However, the status of Cryptops decoratus, Cryptops melanotypus and Cryptops nigropictus, and the species that have here been synonymised with them and of Cryptops songi is uncertain. These species would appear to be closely related. Cryptops nigropictus has been separated from Cryptops decoratus and Cryptops melanotypus on the basis of the nature of the pretarsal spur(s): single and long in Cryptops nigropictus, two and generally shorter in the other two “species”.
Cryptops niloticus fromSudan, Yemen, Rodrigues, Somalia and possibly Eritrea, Cryptops kalobensis from Democratic Republic of Congo and Cryptops basilewskyi from St Helena are synonymised under Cryptops nigropictus
itself recorded from China, Taiwan and the Ryuku Islands. It is thus a
very widely distributed species. The Sudanese populations differ from
others in that some specimens are larger; have more coxosternal pores
and more submarginal coxosternital setae. A similar situation was
reported by
