Relationships - As indicated by Wanless & Lubin ( 1986), this species seems to be related to the diolenid genera, which includes: Chcücolecta Simon, 1884; Diolenius Thorell, 1870; Lystrocteissa Simon, 1884; Sobasina Simon, 1898; Tarodes Pocock, 1899; Udvardya Prószynski, 1992 and others. The elongated first trochanter (together with other characters) might be a good character to limit these genera to a natural group of jumping spiders. The genera-group comprised by Diolenius and related forms requires a revision, which is in progress by Joanna Gardzinska (B. Patoleta pers. comm.). Leptathamas paradoxus Balogh, 1980 (Figs 9-15, 25, 28, 31, 34, 37) Leptathamas paradoxus Balogh, 1980: 25-27. Diagnosis - Carapace with unique shape (Figs 9-10, 28, 34, 37). Posterior slope with a hump (as extension of the ocular area), bearing several (9-14) larger, spine-shaped outgrowth, present on both sexes. Male palp rather simple, embolus thin and twisted. Tibia with a large, retrolateral apophysis (Fig. 25). Epigyne poorly sclerotized (Fig. 14), sperm ducts thick, slightly coiled (Figs 11-13). Description - Male: Thoracic slope brown and with a hump with 9-14 chitinized spine-like outgrowths. Carapace tegument with punctured reticulate microsculpture in the ocular area, covered with fine white hairs. Posterior edge of carapace with brownish hairs. Eyes (except AME) with black surroundings, which are covered with fine white hairs. Chelicerae rather strong, promargin with two teeth, retromargin with a single tooth. Gnathocoxae and sternum light brown. Abdomen with an unclear pattern. Legs yellowish, basal segments (femora, patellae, tibiae) darker, distal segments (metatarsi, tarsi) almost white. Femur, patella and tibia of leg I with thick brushes (Fig. 25). Palp simple. Tibia with a long, single apophysis (Fig. 25). Bulbus elongate, sperm duct clearly visible, embolus tightly coiled. Dimensions (the two known males were measured) - Total length 3.0-3.4. Carapace 1.64-1.72 long, 1.1-1.2 wide at PLE, 1.0-1.05 high at PLE. AEW 0.82, PEW 0.92, eye field 1.1 long. Abdomen 1.2-1.3 long, 0.7-0.9 wide. Holotype (female): Carapace slope with a hump, tegument with papillae, thoracic slope with numerous spine-like outgrowths. Carapace reddish brown, covered with fine white hairs. Black rings around eyes. Chelicerae less robust than on males. Abdomen whitish, with typical "Athamas female-like" dotted pattern. Legs are bleached out, almost white, with no particular pattern.
