Description. Female holotype. Body length 1.9 mm. Ferruginous, moderately shining, antennae and tarsi honey-red. Vestiture of femora, tibiae, at dorsum of rostrum at base, consists of dense, minute, recumbent, translucent golden scales. Erect long golden setae present at base of rostrum and also scattered on pronotal disc; similar shorter recumbent hair-like scales are on each puncture of elytral striae, and few semierect ones are on intervals. Scattered erect golden setae are on femora and tibiae, and few ones may be seen at apex of rostrum and in apical third of its underside. Sparse thin, almost recumbent, golden setae on ventral surface ( Figs 36–38 ).

Head. Rostrum 1.67 times longer than wide at its widest point and 0.63 times as long as pronotum, dilated at base, almost straight and moderately tapering towards apex in lateral view, at base clearly higher than head, dorsum with fine coarse punctures in basal third, then smooth and alutaceous. Scrobes deep, smooth and shining, and almost immediately fused beneath rostrum. Antennae inserted at middle of rostrum. Head separated from rostrum by transverse shallow sulcus.

Pronotum 1.33 times longer than wide, faintly constricted at apex, base truncate, apical margin slightly convex, disc rather flat with large quite sparse punctures, sides weakly curved and feebly sinuous towards apex apicad of widest point of pronotum which is just apicad of middle.

Elytra navicular, 1.71 times longer than wide, maximum width at middle.

Ventral side with large and relatively shallow sparse punctures, metaventrite and abdominal ventrite I with large shallow common depression.

Female genitalia. Spermatheca as depicted in Fig. 39 .

Variability. Other females, apart from the cuticle colour which is more or less dark, are almost identical to the holotype.

Etymology. The Latin name of the new species, a composite noun in apposition, is given after its short scape with a laminar projection over the base of funiculus.

Collection circumstances. Sifted from leaf litter in montane evergreen woodland in the highest parts of the Hagher mountains (J. Hájek, pers. comm.).

Distribution. Endemic to Socotra Island.
