Figs 7–8, 17A

Differential diagnosis

The male of Synagelides logunovi sp. nov. can be easily distinguished from congeners by the presence of a retrolateral patellar apophysis, which is absent in all other congeners. The female of S. logunovi sp. nov. resembles that of S. yinae Liu, Chen, Xu & Peng, 2017 (Liu et al. 2017: figs 7a–d, 8a–b) in the general shape of the copulatory organs, but differs in: 1) epigyne is wider than long in S. logunovi sp. nov. (Fig. 8A), whereas longer than wide in S. yinae (Liu et al. 2017: figs 7c, 8a); 2) the distance between the hood and the apex of median septum is almost as long as hood in S. logunovi sp. nov. (Fig. 8A), whereas more than two times as long as hood in S. yinae (Liu et al. 2017: figs 7c, 8a); 3) spermathecae are pyriform in S. logunovi sp. nov. (Fig. 8 B–C), whereas elongated oval in S. yinae (Liu et al. 2017: figs 7d, 8b).

Etymology

The specific name is the patronym in honor of Dr Dmitri V. Logunov (Manchester, UK), who contributed significantly to the taxonomy of the genus Synagelides .

Description

Male (holotype)

Total length 3.58. Carapace 1.44 long, 1.11 wide. Abdomen 1.94 long, 0.84 wide. Eye sizes and interdistances: AME 0.36, ALE 0.19, PLE 0.18, AREW 1.06, PERW 1.13, EFL 0.88. Legs: I 3.75 (1.15, 1.85, 0.46, 0.29), II 2.40 (0.80, 0.90, 0.51, 0.29), III 2.64 (0.78, 0.90, 0.64, 0.32), IV 3.49 (0.98, 1.34, 0.85, 0.32). Carapace (Fig. 8D) stippled, yellow-brown to dark-brown, eye base black, without distinct patches. Fovea oval, hollowed. Chelicerae (Fig. 8G) pale yellow, with two promarginal teeth and one retromarginal tooth. Endites (Fig. 8E) yellow, with paler prolateral side. Labium (Fig. 8E) brown, paler apically. Sternum (Fig. 8E) yellow. Legs pale yellow to yellow except femur I and the venter of patella I brown. Spination of leg I (Fig. 8H): femur v2-2-2-2-2; metatarsus v0-2-2. Abdomen (Fig. 8 D–E) elongated, contracted medially and slightly broadened posteriorly; dorsum dark-brown, with a narrow transverse pale stripe and two pairs of muscle depressions, posterior herringbone stripes indistinct; venter pale brown. Palp (Figs 7 A–D, 17A): patella slightly longer than wide, distally with sclerotized and flattened retrolateral apophysis; retrolateral tibial apophysis slender, about half as long as cymbium and pointed apically; cymbium hairy, with a distal apophysis; embolus coiled spirally, the basal half almost completely covered by median apophysis in retrolateral view; median apophysis sclerotized and with processes.

Female (allotype, TRU-Salticid-0017)

Total length 3.75. Carapace 1.46 long, 1.12 wide. Abdomen 2.33 long, 1.12 wide. Eye sizes and interdistances: AME 0.36, ALE 0.20, PLE 0.19, AREW 1.11, PERW 1.16, EFL 0.84. Legs: I (1.15, other sections lost), II 2.46 (0.76, 0.90, 0.51, 0.29), III 2.61 (0.76, 0.90, 0.66, 0.29) IV 3.49 (0.98, 1.37, 0.82, 0.32). Habitus (Fig. 8F) similar to that of male except paler, lacking abdominal contraction and the transverse pale stripe on the dorsum of the abdomen. Epigyne (Fig. 8 A–C) wider than long, with an anterior hood slightly longer than wide and a pair of lateral arcuated rims; atrium separated by a big, irregular median septum; copulatory openings located bilaterally; copulatory ducts S-shaped, terminally with short gland ducts extending obliquely; spermathecae pyriform, touching each other antero-medially; fertilization ducts extending transversely.
