Description

Female: Total length 6.28; carapace length 2.50, carapace width 2.57; opisthosoma length 3.98, opisthosoma width 2.61. Eye measurements: AME 0.12; ALE 0.08; PME 0.13; PLE 0.20; AME ‒ AME 0.17; AME ‒ ALE 0.32; PME ‒ PME 0.56; PME ‒ PLE 0.27; AME ‒ PME 0.09; ALE ‒ PLE 0.14. Measurements of legs: I 6.01 (2.05, 2.36, 1.04, 0.56); II 7.30 (2.59, 2.73, 1.45, 0.53); III 7.73 (2.96, 2.56, 1.58, 0.63); IV 6.37 (2.54, 2.03, 1.35, 0.45). Leg formula: III-II-IV-I. Promargin and retromargin of chelicerae with two teeth.

Epigyne (Fig. 1 ): Epigynal field almost inverted heart-shaped. Copulatory openings (CO) oval, laterally located. Posterior part of epigyne with pair of epigynal pockets (EP). Copulatory ducts (CD) thick, with thin turning part. Primary spermathecae (PS) water-drop-shaped, laterally with spermathecal heads (SH) and heavily sclerotised secondary spermathecae (SS); secondary spermathecae (SS) almost as small as spermathecal heads (SH). Fertilisation ducts (FD) straight, shorter than spermathecal heads (SH), located between spermathecal heads (SH) and secondary spermathecae (SS). Posterodorsal folds (PF) membranous, trapezoidal.

Colouration (Fig. 3 A): Carapace almost rounded, light brown, with dark brown fovea and thick hairs. Palps and legs yellow, with brown markings. Opisthosoma yellow, with brown spots, posteriorly with two brown sub-triangular markings.

Male (Figs 2 , 3 B): See Logunov and Jäger (2015).

Diagnosis

The female of Selenops ab Logunov & Jäger, 2015 is similar to those of S. lumbo Corronca, 2001 (cf. Fig. 1 and figs. 51, 52 in Corronca (2002)) in having two distant copulatory openings (CO) laterally, but can be distinguished from it by: 1. epigynal pockets (EP) posteriorly located (vs. medially located); 2. turning part of copulatory ducts (CD) thin, almost 1 / 3 as wide as the rest (vs. thick, almost as wide as copulatory ducts (CD )); 3. primary spermathecae (PS) water-drop-shaped (vs. double spherical); and 4. fertilisation ducts (FD) short and straight (vs. long and curved). For the male, see Logunov and Jäger (2015).

Distribution

China (Guangdong; new record), Vietnam (Fig. 4 ).

Biology

This species was found in crevices of tree trunks and on railings in Wutong Mountain, Shenzhen (Fig. 5 ).
