Differential diagnosis

Synagelides subgambosus sp. nov. closely resembles S. gambosus ( Xie & Yin 1990: figs 1–7; Fig. 11D ) in the shape of the copulatory organs and habitus but differs in: 1) the terminal edge of median apophysis is smooth in retrolateral view in S. subgambosus sp. nov. ( Fig. 11B ), whereas it is distinctly serrated in S. gambosus ( Fig. 11D ); 2) the middle portion of median apophysis is about four-fifths the width of the terminal portion in retrolateral view in S. subgambosus sp. nov. ( Fig. 11B ), whereas it is about half the width of terminal portion in S. gambosus ( Fig. 11D ); 3) gland ducts are more than two-thirds as long as spermatheca in S. subgambosus sp. nov. ( Fig. 12C ), whereas less than one-fourth as long as spermatheca in S. gambosus ( Xie & Yin 1990: fig. 7). Synangelides subgambosus sp. nov. also somewhat resembles S. bohdanowiczi sp. nov. and the diagnostic features of this species are discussed above.

Etymology

The specific name refers to its similarity with S. gambosus , noun.

Legs: I 4.19 (1.32, 2.17, 0.41, 0.29), II 2.75 (0.85, 1.02, 0.56, 0.32), III 2.91 (0.88, 0.98, 0.71, 0.34), IV 3.87 (1.12, 1.41, 0.95, 0.39). Carapace ( Fig. 12D ) stippled, red-brown, darker anteriorly, covered with thin hairs antero-medially. Fovea oval, hollowed. Chelicerae ( Fig. 12G ) yellow, with two promarginal teeth and one retromarginal tooth fissident. Endites, labium and sternum ( Fig. 12E ) yellow. Legs pale yellow to red-yellow except femora I and IV red-brown. Spination of leg I ( Fig. 12H ): femur v2-2-2-2; metatarsus v0-2-2. Abdomen ( Fig. 12 D–E) elongated, dorsum with 2 pairs of muscle depressions and 2 transverse pale patches medially; venter gray-white, with a pair of pale brown lines extending from epigastric furrow to the terminus. Palp ( Fig. 11 A–C): patella swollen; tibia almost as long as wide; retrolateral tibial apophysis S-shaped, originating from the middle part of tibia; cymbium with a well-developed retrolateral apophysis; embolus enlarged at base, strongly curved medially and blunt at tip; median apophysis flattened, slightly broadened terminally, and with a triangular process at the anterior edge in retrolateral view.

Female (allotype, TRU-Salticid-0032)

Total length 4.22. Carapace 1.73 long, 1.18 wide. Abdomen 2.43 long, 1.55 wide. Eye sizes and interdistances: AME 0.38, ALE 0.24, PLE 0.22, AREW 1.18, PERW 1.20, EFL 0.96. Legs: I 3.81 (1.20, 1.88, 0.44, 0.29), II 2.74 (0.85, 1.01, 0.56, 0.32), III 2.94 (0.85, 1.01, 0.76, 0.32), IV 4.08 (1.15, 1.51, 1.05, 0.37). Habitus ( Fig. 12F ) similar to that of male except paler. Epigyne ( Fig. 12 A–C) slightly wider than long, with a pair of lateral arcuated rims; atrium large, almost covering two-thirds the epigyne, separated by a narrow median septum; copulatory openings located postero-laterally; copulatory ducts extending transversely at antero-median part and then descending posteriorly along the longitudinal axis, terminally with well-developed gland ducts which are longer than the fertilization ducts; spermathecae elongated, extending transversely and touching each other prolaterally; fertilization ducts short.
