Synagelides Strand, 1906 View in CoL View at ENA

Synagelides Strand in Bosenberg & Strand 1906: 330 View in CoL (type species: Synagelides agoriformis Strand, 1906 View in CoL ).

Diagnosis: Synagelides can be recognized by the strikingly modified male palps with enlarged patella with a femur connected at 90°, and presence of femoral apophysis ( Figs 7 View FIGURE 7 E–F, 8D, 8F), several apical tibial apophysis, spirally arranged embolus ( Figs 1 View FIGURE 1 D–E, 2A–C, 4D, 5B–C, 7D–F, 8A–F, 9C–E) and epigyne with arcuated rims and pockets ( Figs 2 View FIGURE 2 D–E, 3C–E, H–J, 5D–E). Further, the ant-like sandy brown habitus ( Figs 1A, 1C View FIGURE 1 , 3A, F View FIGURE 3 , 4A View FIGURE 4 , 6 View FIGURE 6 A–D, 7A, 9A), patella I as long as femur I, elongated front legs with long and stout spines on metatarsi and tibiae ( Prószyński 2009) separate Synagelides from most other jumping spiders.

Synagelides are similar to Agorius Thorell, 1877 , but differ by the more compact body (elongate with abdomen constricted in the middle in Agorius ). However, some Synagelides also seem to possess the above characters and cannot be unambiguously separated from Agorius .

Description: Small, ant-like spiders with size ranging from 2–4 mm in length ( Bohdanowicz 1987; Logunov & Hereward 2006). Flattened and stippled prosoma with distinct fovea ( Liu et al. 2017). Square-shaped ocular quadrangle. Cervical groove in between PMEs. Chelicerae with 2 promarginal teeth and one large retromarginal tooth with a bifurcated tip ( Liu et al. 2017). Leg formula: I, IV, III and II. Front legs elongated with massive femur and long and rigid spines on metatarsi and tibiae I ( Prószyński 2009). Other legs lack spines ( Logunov 2017). Oval abdomen with ‘herringbone-like’ dorsal patterns at posterior region ( Bohdanowicz 1987; Liu et al. 2017). Male palp with massive patella, prolateral femoral apophysis articulates on bulges of patella and tibia, long and slender RTA lies in alveolus of cymbium, posterior apophysis on dorsal cymbium, massive bulb with distal hook-shaped apophyses on prolateral side, triangular dorsal cymbium, short embolus broad at spiral base ( Figs 1 View FIGURE 1 D–E, 2A–C, 4D, 5B–C, 7D–F, 8A–F, 9C–E) and developed median apophysis ( Figs 1 View FIGURE 1 D–E, 2B) in some species ( Bohdanowicz 1987). Epigyne characterized with fossae ( Figs 2 View FIGURE 2 D–E, 3C–E, H–J, 5D–E), sculptures and pockets, arcuated rims separated by median septum, inconspicuous copulatory openings, developed copulatory duct and oval spermathecae ( Bohdanowicz 1987; Liu et al. 2017).
