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.

Distribution
