Notes

Simon (1903) created the generic name Eusparassus to substitute it for the name Sparassus ; because he suspected that Sparassus was a junior synonym of Micrommata ( Simon 1903: 1020) . Simon (1903) designated the type species as Eusparassus argelasius denoted by a new replacement name (nomen novum) for the name of misidentified M. argelasia (published in Latreille 1818). Since this species could be mistaken with Olios argelasius , type of Olios Walckenaer,1805 (sub Sparassus argelasius ) Simon (1932) presented E. dufouri as a new species.

Type species

Eusparassus dufouri Simon, 1932 View in CoL by original designation in Simon (1903) sub E. argelasius , female from Spain.

Extended diagnosis

Eusparassus spp. can be diagnosed from the other two monotypic genera of Eusparassinae by the number of ventral tibial spines: I–IV four (six in Arandisa and Pseudomicrommata ) and by relative diameters of AME, which is subequal to or larger than ALE (in the other two genera, AME smaller than ALE); Eusparassus spp. are recognizable by the shape of copulatory structures: parallel embolus and tegulum constructing a U-shaped structure, embolus membrane partially covering embolus tip; dRTA strong and straight, in contrast to dRTA, vRTA small and weakly developed ( Figures 2A View Figure 2 , 11G View Figure 11 , 19A View Figure 19 ); Female epigyne characterized by two large triangular lateral lobes, LL parallel and in contact on the median longitudinal suture and diverging at posterior margins strongly and at anterior margins slightly and circumscribing MS entirely ( Figures 3A View Figure 3 , 4C View Figure 4 ) or partially ( Figures 5F View Figure 5 , 8A View Figure 8 , 16A View Figure 16 , 21A View Figure 21 ); in vulva, dorsal view, two parallel copulatory ducts, straight and fully or partially hyaline, folded and membranous ( Figure 3B View Figure 3 ).

Redescription

Medium to large Sparassidae , body length 10 mm (e.g. E. oculatus ) to 30 mm (e.g. E. xerxes comb. nov.); prosoma slightly longer than wide. Leg length formula 2 4 1 3 (most species) or 2 4=1 3; eyes arranged in two rows, anterior row slightly recurved and posterior row relatively straight, eyes about subequal in size, AME slightly larger than or subequal to ALE; Basal segment of chelicerae at distal retromarginal end with one ( Figures 2E View Figure 2 , 7B View Figure 7 ) to three or four thick bristles ( Figures 19E View Figure 19 , 22D View Figure 22 ), in most species just one bristle. Chelicerae with two anterior and three to six posterior teeth, Cheliceral furrow with ( Figure 4B View Figure 4 ) or without ( Figures 2E View Figure 2 , 9B View Figure 9 , 21D View Figure 21 ) denticles; ventral tibial spines: I–IV four, spination of other parts variable but in most species: Palp 131, 101, 1111, 1013. Legs: Femur I–III 323, IV 322; Patella I–IV 101; Tibia I–IV 2024; Metatarsus I–III 2024, IV 3034 / 3036; male palp as in diagnosis with embolus originating at 6:30 (o’clock position) running first distally and bent retrolaterally, tip of embolus pointing in various angles and with diverse shapes, embolus and tegulum forming a U-shaped structure in ventral view; small and hyaline conductor situated at distal end of tegulum and partially covering tip of embolus ( Figures 11E View Figure 11 , 12B View Figure 12 ). Female epigyne consisting of two large triangular lateral lobes, LL parallel and in contact on the median longitudinal suture; MS soft and hyaline ( Figure 5F View Figure 5 ) or hard and sclerotized ( Figure 22E View Figure 22 ), EF fusing anteriorly and constructing EFB ( Figures 17F View Figure 17 , 20A View Figure 20 ) or not ( Figure 16A View Figure 16 ); internal duct system with glandular pores situated in a depression ( Figures 5G View Figure 5 , 6B, D View Figure 6 ) or on a projection ( Figures 2C View Figure 2 , 8B View Figure 8 , 22F View Figure 22 ).

Colouration

Pale grey to dark brown spiders, with uniform colouration of body ( Figure 1C View Figure 1 ) or clearly patterned body and banded legs ( Figure 1B View Figure 1 ), ventral opisthosoma with distinct dark marking ( Figure 23 View Figure 23 B-D) or pale ( Figure 23A View Figure 23 ), dorsal opisthosoma with a pattern of small chevrons in posterior half.
