( Fig. 29 )

Type material. HOLOTYPE: ♀ ( NMPC), ‘ Yemen, Socotra island // Homhil, protected area // open woodland with Boswellia & // Dracaena trees; 10-11.vi.2012 // 12°34.5′N, 54°18.5′E, 360-500 m’, ‘ Socotra expedition 2012 // J.

PARATYPES: 1 ♀, same label data as holotype ( ECRI); 1 ♀, ‘ Yemen, Socotra island // Kazazhan area // shrubland on limestone; sifting // 10.vi.2012 // 12°33.8′N, 54°19.8′E, 540 m’, ‘ Socotra expedition 2012 // J. Bezděk, J. Hájek, V. Hula, // P. Kment, I. Malenovský, // J. Niedobová & L. Purchart leg.’ ( NMPC).

Description. Female holotype. Body length 1.7 mm. Brownish, opaque, antennae, unci and tarsi honey-red, tibiae dark ferruginous. Erect, thin, yellowish claviform setae clothing all dorsal surface, dorsal margin of legs and sides of rostrum. Thin, slightly erect golden setae are very sparse on ventrites ( Fig. 29 ).

Head. Rostrum 1.85 times longer than wide at its widest point and 0.70 times as long as pronotum, moderately dilated at apex, regularly curved and slightly widening towards apex in lateral view, dorsum alutaceous and faintly strigose at base. Scrobes large, rather deep, smooth, and reaching basally up to distance about equal to eye diameter. Antennae inserted at base of apical quarter of rostrum.

Pronotum about as long as wide, widest at basal third; disc rather flat, with large not very dense roundish punctures, sides almost curved towards apical constriction and towards base, apex slightly curved, base straight and little wider than apex.

Elytra 1.33 times as long as wide, oval, maximum width at middle. Striae formed by large rather deep irregular punctures. Intervals flat and not wider than striae.

Legs. Femora moderately elongate, upper margin more strongly curved than lower one; tibiae almost straight, internal margin of protibiae minutely setose on apical third.

Ventral side punctured, except ventrites III to V.

Variability. Other females are similar to the holotype, one of them is slightly immature and has integument pale brownish.

Body length 1.7–2.0 mm.

Differential diagnosis. A species distinguished at once by its setose dorsal surface, obvious clubbed setae on rostral sides, and oval shape of pronotum and elytra.

Etymology. The Latin name, hispidirostris (- is, - e), is a composite adjective referring to its setose rostrum.

Collection circumstances. Sifted from leaf litter under Ficus vasta Forssk. (Moraceae) in karstic terrain (J. Hájek pers. comm.).

Distribution. Endemic to Socotra Island.
