Cryptothele collina Pocock, 1901: 498 (sex or stage not specified).

Type material. Holotype ♀ (damaged) from INDIA: Tamil Nadu: Nilgiris: Ooty / Udhagamandalam (=Ootacamund) (11°24'N, 76°41'E; 2251 m alt.), date unknown, G.F. Hampson leg., repository NHM (no register number), examined based on photographs. GoogleMaps

Diagnosis. Females of C. collina are closely related to the females of Cryptothele alluaudi Simon, 1893 as the epigyne of both share broad, paired lateral plates and narrow median septum. However, it can be separated from the latter by anterior epigynal hood (vz. absent in C. alluaudi ) and epigyne without lateral pockets (vz. present in C. alluaudi ) (compare Fig. 1C View FIGURE 1 with Marusik & Omelko 2012: fig. 4).

Redescription. Female (holotype, Fig. 1A–B View FIGURE 1 ) in alcohol (after Pocock 1901): overall body with thick cover of mud and soil particles, except for mouth parts and epigyne ( Fig. 1A–B View FIGURE 1 ). Prosoma high, with abruptly sloped thoracic part. Cephalic part with distinct, transversely oval pit behind PER. Thoracic part with sinuous margin ( Fig. 1A View FIGURE 1 ). AMEs largest. Labium unfused with sternum ( Fig. 1B View FIGURE 1 ). Sternum oval, with anterior concavity ( Fig. 1B View FIGURE 1 ). Opisthosoma globular ( Fig. 1A View FIGURE 1 ). Body length 10.00. Carapace 4.50 long. Epigyne ( Fig. 1C View FIGURE 1 ): sclerotized, with anterior hood and broad, paired lateral plates having posterolateral horny lobes, with narrow heart-shaped median septum. Copulatory openings indistinct.

Male. Unknown.

Note. The NHM collection has a single female specimen (holotype) and the original description of this species was based on it (J. Beccaloni, pers. comm.) ( Fig. 1 View FIGURE 1 ). It lost its legs, except for the femur and patella of anterior right leg II ( Fig. 1A–B View FIGURE 1 ). Details of vulva are unknown as we were not allowed to dissect and examine it.

Comments. Pre-epigyne and pre-vulva in Cryptothele species: pre-epigynes and pre-vulvae are illustrated several times for many spider families ( Bayer 2011). However, up to now, no information regarding pre-epigyne and pre-vulva in Zodariidae are available. Recently the first author had an opportunity to examine a few individuals of a Cryptothele species collected from the Kottayam district of the southern Indian state of Kerala (ADSH191) ( Fig. 2 View FIGURE 2 ). These specimens are subadult females that had developed some faintly sclerotized sculpturing in the genital area ( Fig. 2E–F View FIGURE 2 ). The preepigyne and pre-vulva are clearly apparent in these specimens ( Fig. 2E–F View FIGURE 2 ) and, compared to the epigynes of adult Cryptothele species, are structurally quite distinct. The pre-epigyne is weakly sclerotized, with a broad median septum and paired lateral circular atria ( Figs 2E View FIGURE 2 , 3A View FIGURE 3 ) (compare with Fig. 1C View FIGURE 1 and also Koch 1872: fig. 2g; Workman 1896: fig. 77f; Kulczyński 1911: plate XXI, figs 30–32; Marusik & Omelko 2012: fig. 4). Copulatory openings indistinct as in the case of adult stages. As of yet, the vulva of Cryptothele species is not illustrated and comparison of pre-vulva illustrated here is not possible. Copulatory ducts of pre-vulva hyaline, moderately long, wide, longitudinally oriented ( Figs 2F View FIGURE 2 , 3B View FIGURE 3 ). Spermathecae roughly globular, sclerotized ( Figs 2F View FIGURE 2 , 3B View FIGURE 3 ). Fertilisation ducts long, converging ( Fig. 3B View FIGURE 3 ).
