Amphidraus and Nebridia - wholesale merging

Merging of these genera, proposed by Zhang & Maddison (2015: 22-23), is not supported by diagnostic drawings of respective type species by Galiano 1963b (see comparative drawing at Fig. 37Q 1 ) and Bryant 1943 ( Fig. 37P) and therefore is not acceptable. Attention: Nebridia manni Bryant, 1943 ( Fig. 37P 1 ) and N. mendica Bryant, 1943 ( Fig. 37P 2 ) are misplaced, neither Nebridia nor Amphidraus , there is genus not identifiable by existing diagnostic drawings (see also files http://www.peckhamia.com/salticidae/q10- Neb.html and http://www.peckhamia.com/salticidae/q10-Amphid.html). Therefore:

Amphidraus semicanus (Simon, 1902) = Nebridia semicana Simon, 1902d: 373 (reinstated original

combination, documented by Fig. 37P, compare with Fig. 37Q 1 ).

Amphidraus manni (Bryant 1943) = Nebridia manni Bryant 1943 (transfer reversed due to palp

incompatibility, compare Figs 37P 1 and 37Q 1 , also files mentioned above, pending further search),

Amphidraus mendica (Bryant 1943) = Nebridia mendica Bryant 1943 (transfer reversed due to palp

incompatibility, compare Figs 37P 2 and 37Q 1 , see also files mentioned above, pending further

search).

Ascyltus or Omoedus ?

Palp of this species looks very different from Zenodorus , where was placed by Żabka (1988b: 476-478, f. 151, 156) (compare Figs. 1B 8 and 1C 8, also 38G-H with 38I). It seems to be comparable (but not identical) with some Ascyltus ( Fig. 33Q) by broad anterior part of bulbus, broad, loose coil of embolus in the plane parallel to bulbus and by almost straight, slightly oblique course of spermophor. On the other hand it differs by rather special ducts and spermatheca, short tibial apophysis and lack of transverse enlargement of the face. The proposed placement is tentative and most probably the species should be placed in an own genus.

Therefore:

Omoedus asper (Karsch, 1878) = Ascyltus asper (Karsch, 1878) ,

Genitalic charaters: A-B - palp in standard position, C - epigyne, external view, D - internal structure of epigyne: note copulatory openings, ducts, spermathecae (with pheromone exuding pore, developed here duct like, pockets), E-H - morphological characters of this particular genus, E – lateral subocular row of stridulatory bristles on tubercles, F - modified leg I, G - variation in shape and spination of tibia I, left and right in the same specimens, upper male, lower - female, H - male and female variation in tibia I in another species, I-K - body shape and color pattern in male, L - the same in female.
