Summary: | Acantholycosa kronestedti sp. n. Figs 2f‒j, 3d‒f, 4d‒f, 5d‒f, 6d‒f, 9b, 10 Types. Holotype ♂ (MMUE, G7615.1) MONGOLIA, Govi-Altai Aimag, Khasagtyn-Nuruu Mt. Range, near Khoit-Bogd-Uul Mt. (46°48'N, 95°49'E), dry stony riverbed, 2800‒2900 m, 8.07.2017 (A.A. Fomichev). Paratypes: 1♂ 3♀ (MMUE, G7615.2) same locality (46°47'N, 95°50'E), mountain stony tundra with screes and rocks, 3400‒3500 m, 8.07.2017 (A.A. Fomichev). Etymology. The specific name is a patronym in honor of our good friend and colleague, Torbjörn Kronestedt (Stockholm, Sweden), a well-known spider taxonomist who has made many important contributions to the arachnology. Diagnosis. The male of A. kronestedti sp. n. can be distinguished from all its congeners by the presence of 2 embolic spines, one in the embolic base and another in its anterior half (Figs 2f, h, 3d, 4d, f, 5f) vs. either only a basal spine or no spines at all. The female of A. kronestedti sp. n. is most similar to that of A. vahterae sp. n. in having an arch-shaped anterior pocket and well-developed septal lateral lobes. The two species can be distinguished by the shape and size of the lateral septal lobes, almost triangular with slanting lateral margins in A. kronestedti sp. n. and longer than wide with subparallel lateral margins in A. vahterae sp. n. (cf. Figs 6d‒f and 6a‒c). Description. Male (holotype). Total length 7.4. Carapace 3.9 long, 3.2 wide. Coloration: carapace, sternum and chelicerae black. Labium and endites yellow-gray. Palps: Fe‒Ti dark brown, cymbium black with yellow top. Legs: Fe black, Pt‒Ta yellow-gray. Leg IV darker than others. Abdomen black. Spination of leg I: Fe d1-1-1 p0-0- 2 r0-1-1; Pt p1 r1; Ti p1-0-0 r1-0-0 v2-2 -2-2; Mt p0-1-0 r0-1-0 v2-2. Palp as in Figs 2f‒j, 3d‒f, 4d‒f, 5d‒f. Tegular apophysis without anterior arm. Embolus broad, with a large basal spine (Es) similar to a large triangular lamina, and a small spine (Ss) in its middle part; tip slightly widened. Paleal apophysis flat lanceolate; terminal apophysis with a spine-like process (Sp). ... |
