Etymology.

The specific name is after one of the most popular surnames (An) in Vietnam; noun (name) in genitive case.

Diagnosis.

The male of Synagelides ani sp. nov. closely resembles S. leigongensis Wang, Mi, Irfan & Peng, 2020 in having a very similar palp, especially the needle-shaped division of the RTA, but it can be easily distinguished by the RTA, which is acutely narrowed distally to a rather pointed tip and with a straight needle-shaped division in retrolateral view (Fig. 15B ), but the RTA is blunt apically with a curved, needle-shaped division in S. leigongensis ( Wang et al. 2020: fig. 5B). The female of this new species resembles S. xingdouensis Wang, Mi, Irfan & Peng, 2020 in having longitudinally extending spermathecae, but it can be easily distinguished by the following: (1) the presence of an epigynal hood (Fig. 16A, B ), which is absent in S. xingdouensis ( Wang et al. 2020: fig. 16A, B); (2) the atrium is as wide as the epigyne (Fig. 16A, B ), whereas it is ~ 1/3 the epigynal width in S. xingdouensis ( Wang et al. 2020: fig. 16A, B).

Description.

Male (Figs 15 , 16D, E, G, H ). Total length 3.94. Carapace 1.98 long 1.40 wide. Abdomen 2.04 long, 1.02 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.48, ALE 0.26, PLE 0.26, AERW 1.35, PERW 1.33, EFL 1.07. Legs: I 5.94 (1.88, 1.75, 1.33, 0.63, 0.35), II 3.40 (1.01, 0.50, 0.83, 0.73, 0.33), III 3.46 (0.98, 0.50, 0.80, 0.85, 0.33), IV 4.53 (1.25, 0.65, 1.20, 1.08, 0.35). Carapace stippled, yellow-red to dark, covered with white and brown setae, with pair of irregular dark patches anteromedially on eye field; fovea oval. Chelicerae yellow, with two promarginal teeth and one retromarginal fissidental tooth with two cusps. Endites red-yellow, almost square, bearing dense setae on paler inner margins. Labium colored as endites, almost linguiform. Sternum red-yellow, longer than wide, almost shield-shaped. Legs yellow except femora I red-brown, with seven (2-2-2-1) and two spines on tibiae I and metatarsi I, respectively. Abdomen elongated, dorsum yellow to dark brown, with longitudinal, sub-trapeziform patch anteriorly, pair of muscle depressions, two transverse, yellow stripes medially, and two clusters of white setae mediolaterally; venter yellow to brown, with dotted lines medially. Palp (Fig. 15A-E ): femur longer than wide, with triangular disto-prolateral apophysis; patella enlarged, longer than wide; tibia short, with sclerotized, sub-triangular PTA, and robust RTA with dolphin-shaped longitudinal part, and membranous, needle-shaped inner division; cymbium longer than wide in ventral view; bulb swollen; embolus twisted, tapered; MA sclerotized, irregular, retrolateral to embolus, with small processes distally.

Female (Fig. 16A-C, F ). Total length 5.39. Carapace 2.29 long 1.61 wide. Abdomen 3.14 long, 1.57 wide. Clypeus 0.02 high. Eye sizes and inter-distances: AME 0.53, ALE 0.31, PLE 0.31, AERW 1.64, PERW 1.63, EFL 1.39. Legs: I 5.14 (1.63, 1.50, 1.18, 0.50, 0.33), II 3.67 (1.08, 0.55, 0.88, 0.78, 0.38), III 3.92 (1.10, 0.55, 0.88, 1.01, 0.38), IV 5.28 (1.38, 0.75, 1.40, 1.35, 0.40). Habitus (Fig. 16F ) similar to that of male except paler and without distinct dark patches on eye field. Epigyne (Fig. 16A-C ): wider than long, with small, broad, central hood; atrium oval, separated by the broad, irregularly-shaped median septum, with pair of arc-shaped lateral ridges; copulatory openings beneath the base of atrial ridges; copulatory ducts straight, transversely extending at proximal half, continuing, slightly curving and followed by invisible parts; spermathecae longitudinal extending, ~ 2.5 × longer than wide, touched, tapered posteriorly; fertilization ducts originate from anterior portions of spermathecae, lamellar.

Distribution.

Known only from the type locality in Vinh Phuc, Vietnam.
