Figs 1–2 , 17C

Differential diagnosis

Synagelides bohdanowiczi sp. nov. resembles S. gambosus ( Xie & Yin 1990: figs 1–7; Fig. 11D ) and S. subgambosus sp. nov. in the S-shaped retrolateral tibial apophysis and the long and narrow median septum in the epigyne, but differs from these two species by: 1) retrolateral tibial apophysis originates from the terminal of the tibia, with the tip directed upwards in retrolateral view in S. bohdanowiczi sp. nov. ( Fig. 1B ), whereas originates from the middle of the tibia, with the tip directed horizontally towards the genital bulb in S. gambosus ( Fig. 11D ) and S. subgambosus sp. nov. ( Fig. 11B ); 2) median apophysis is horn-shaped, pointed and far away from the embolus apically in S. bohdanowiczi sp. nov. ( Fig. 1B ), whereas more broadened and very close to or partially covering the embolus in S. gambosus ( Fig. 11D ) and S. subgambosus sp. nov. ( Fig. 11B ); 3) atrium is elongated oval, longer than wide, lacking wrinkles in S. bohdanowiczi sp. nov. ( Fig. 2A ), whereas wider than long, with distinct wrinkles in S. subgambosus sp. nov. ( Fig. 12A ); 4) spermathecae extend obliquely in dorsal view in S. bohdanowiczi sp. nov. ( Fig. 2C ), whereas extend transversely in S. gambosus ( Xie & Yin 1990: fig. 7) and S. subgambosus sp. nov. ( Fig. 12C ).

Etymology

The specific name is a patronym in honor of Dr Andrzej Bohdanowicz, who contributed extensively to the taxonomy of the genus Synagelides .

Description

Male (holotype)

Total length 5.04. Carapace 2.04 long, 1.52 wide. Abdomen 2.83 wide, 1.02 wide. Eye sizes and interdistances: AME 0.48, ALE 0.26, PLE 0.24, AREW 1.48, PERW 1.50, EFL 1.15. Legs: I 6.11 (1.88, 3.18, 0.61, 0.44), II 3.87 (1.12, 1.46, 0.85, 0.44), III 4.05 (1.15, 1.44, 1.02, 0.44), IV 5.47 (1.44, 2.10, 1.39, 0.54). Carapace ( Fig. 2D ) stippled, red-brown, anterior surface and eye base dark, covered by brown hairs anteriorly and sparse white hairs posteriorly. Fovea oval, hollowed. Chelicerae ( Fig. 2G ) yellow, with two promarginal teeth and one retromarginal tooth fissident. Endites ( Fig. 2E ) yellowbrown, slightly longer than wide, inner margins pale with dense hairs. Labium ( Fig. 2E ) gradually narrowed, apically bearing dense hairs. Sternum ( Fig. 2E ) yellow, scutiform. Legs yellow to red-yellow except the basal half of femur I dark. Spination of leg I ( Fig. 2H ): femur v2-2-2-2; metatarsus v0-1-1. Abdomen ( Fig. 2 D–E) elongated; dorsum dark-brown, the posterior one-third portion darker, with a pair of round spots antero-medially, and an inconsecutive, longitudinal pale-brown stripe extending from the anterior margin to the posterior one-third portion; venter gray, with two longitudinal dark-brown stripes bilaterally and two longitudinal lines medially. Palp ( Figs 1 A–D, 17C): patella about 1.5 times longer than wide in retrolateral view; retrolateral tibial apophysis S-shaped, broadened at base; cymbium hairy, with sclerotized prolateral apophysis tapering to a pointed tip in dorsal view; bulb bulged, with the sperm duct extending along the margin; embolus with flatted, semicircular base, distal portion flagelliform, and tip slightly pointed, reaching the cymbium apex; median apophysis ox horn-shaped in retrolateral view, the distal half sclerotized.

Female (allotype, TRU-Salticid-0011)

Total length 4.85. Carapace 1.93 long, 1.37 wide. Abdomen 2.70 long, 1.01 wide. Eye sizes and interdistances: AME 0.47, ALE 0.25, PLE 0.24, AREW 1.40, PERW 1.45, EFL 1.10. Legs: I 4.83 (1.46, 2.44, 0.49, 0.44), II 3.54 (1.05, 1.29, 0.76, 0.44), III 3.68 (1.07, 1.24, 0.93, 0.44), IV 5.21 (1.37, 2.01, 1.29, 0.54). Habitus ( Fig. 2F ) similar to that of male except paler and with a pair of white oval patches on the dorsum of the abdomen. Epigyne ( Fig. 2 A–C) wider than long; atrium large, separated by a) (-shaped median septum; copulatory openings located bilaterally; copulatory ducts long, descending obliquely before extending transversely, and then descending posteriorly along the longitudinal axis, terminally with short gland ducts; spermathecae long, oval, touching each other anteriorly; fertilization ducts anterior to spermathecae.

Distribution

China (Guangxi) ( Fig. 18 ).

Comments

At first glance, the male and female look different in the markings of the abdomen. However, the male has blurry markings almost identical to the female. Furthermore, both of them were collected from the same locality and the sexual dimorphism in the morphology of the copulatory organs is consistent with sexual dimorphism in related species ( S. gambosus and S. subgambosus sp. nov.). Based on this evidence, they are proposed to be the same species.
