Apochinomma dolosum Simon, 1897

Fig. 1

Apochinomma dolosum Simon, 1897a: 261 (♀); Majumder & Tikader, 1991: 158, figs 334–337 (♀).

Type material. Syntypes 2♀ from INDIA: Uttarakhand: Dehradun (=Dehra-Dun) (30°18’N, 78°01’E; 656 m a.s.l.), leg. M.A. Smythies, date unknown, MNHN 13446 , examined based on photographs .

Diagnosis. Females of A. dolosum are similar to the females of A. malkini Haddad, 2013 , as both have copulatory openings at the midpoint of the epigyne, but can be separated from the latter by obliquely oriented rims of the copulatory openings (vs. comma-shaped in A. malkini ) (compare Fig. 1B with Haddad 2013: fig. 12C).

Description. For description of the female, see Simon (1897a).

Supplementary description. Female. Dorsal scutum of opisthosoma small, restricted anteriorly ( Fig. 1A ). Epigyne ( Fig. 1B ): epigynal plate triangular, with W-shaped posterior margin. Copulatory openings large, with obliquely orientated lateral rims.

Male. Unknown.

Remarks. Apochinomma dolosum is distinct from A. nitidum , as it has oblique lateral rims of copulatory openings, which are C-shaped in A. nitidum (compare Fig. 1B with Fig. 3H–I, K ), and thus it could not be a synonym of A. nitidum , as doubted by Deeleman-Reinhold (2001).
