Differential diagnosis

Urometopus sengleti sp. nov. is closely related to U. talyschensis and shares with it most of the external habitus characters and general shape of spermatheca, but differs from the latter in globose elytra with strongly convex disc, narrower epifrons and sparsely punctate pronotum; ramus of spermatheca perpendicular to collum.

Etymology

This species is named after Dr Antoine Senglet (1927–2015), Swiss entomologist and arachnologist who collected this species.

Description

MEASUREMENTS (mm). BL: 2.79–2.82, BW: 1.53, BH: 1.24–1.29.

COLORATION AND VESTITURE (Fig. 36A). Yellow-brown; erect and recumbent setae distinct; erect setae yellowish-grey, narrow and somewhat flattened, pointed and obtuse, somewhat shorter than width of interstriae, ordered in regular row; interstriae sparsely covered with recumbent piliform setae; each puncture in striae bears tinier subrecumbent piliform seta. Head vestiture: setose, setae erect. Vestiture of antennae and legs setose; scape and funicle with recumbent setae; grooming brush on distal ⅓ of medial margin of metatibia weakly developed, contains short pale subrecumbent piliform setae.

HEAD (Fig. 36B). Rostrum slightly narrowing anteriorly; RL/RW = 0.74–0.79. Pterygia projected. Frons: U-shaped, nitid, weakly sloped anteriorly, not delimited from epistome by thin V-shaped carina. Epifrons well edged, parallel-sided, 2× as narrow as vertex, flat, without median sulcus, striate. Vertex without transverse depression. Eyes moderately convex; VW/ELD = 1.95–2.00. Costulation of head capsule continues on epifrons.

ANTENNAE. Scape reaches anterior margin of pronotum, evenly arcuate and widened apically; funicle slender; funicular antennomeres L/W: fam1 = 1.61, fam2 = 1.80, fam3 = 0.85, fam4 = 0.79, fam5 = 0.75, fam6 = 0.73, fam7 = 0.65; club L/W = 1.87.

THORAX. Pronotum: PL/PW = 0.77–0.82, moderately transverse; convex on disc; widest at middle, roundly narrowing anteriorly and weakly constricted posteriorly; sparsely punctate, punctures irregular, interspaces between punctures wider than diameter of puncture. Elytra orbicular-ovate, strongly convex, EL/EW = 1.25.

LEGS. Tibiae slender. Medial margin of protibiae and metatibiae moderately emarginate; mucro weak. Tarsi: 1 st tarsomere as wide as 2 nd; 2 nd tarsomere 1.8 × as wide as long.

FEMALE GENITALIA. Spermatheca (Fig. 36C): nodulus moderately tumid; collum weakly projecting, narrow, in line with nodulus; ramus weakly projecting, narrow, perpendicular to nodulus; cornu strongly attenuate.

MALE. Unknown.
