Figs 9–10
Synagelides longus Song & Chai, 1992: 82, fig. 10a–c (d = ♀).
Synagelides longus – Song & Li 1997: 441, fig. 52a–c (♀). — Song et al. 1999: 561, fig. 319h (♀).
Differential diagnosis
Synagelides longus resembles S. palpalis Żabka, 1985 (Żabka 1985: figs 573–580; Fig. 17D) in the general shape of the copulatory organs and habitus, but differs in: 1) retrolateral tibial apophysis is shorter than half the cymbial length, slightly broadened medially and curved apically in retrolateral view
in S. longus (Fig. 9B), whereas longer than half the cymbial length, tapered and straight in S. palpalis (Fig. 17D); 2) epigynal hood is about two times wider than long in S. longus (Fig. 10A), whereas about two times longer than wide in S. palpalis (Żabka 1985: fig. 577).

Spination of leg I (Fig. 10H): femur v2-2-2-2; metatarsus v0-1-1. Abdomen (Fig. 10 D–E) elongated, slightly contracted medially; dorsum brown, pale median-laterally and dark posteriorly, with two pairs of muscle depressions and herringbone stripes; venter pale brown to dark brown, with dots posteriorly. Palp (Fig. 9 A–F): patella swollen; tibia wider than long; retrolateral tibial apophysis L-shaped and sclerotized, slightly broadened medially and curved apically; cymbium with dorsal and prolateral apophyses; bulb inflated, with sperm duct extending along margin; embolus coiled spirally, apically extending above the cymbium apex; median apophysis strongly sclerotized, consisting of square and trapeziform parts in retrolateral view.
