Hajekia microps View in CoL sp. nov.

( Figs 16, 17, 19 View Figs 16–21. 16–17, 19 )

Type material. HOLOTYPE: J ( NMPC), ‘ Yemen,Socotra island // Al Haghier Mts. // Skant Mt. env. 1450 m // 12°34.6′N E 54°01.5′E // Jiří Hájek leg. 12-13.xi.2010 GoogleMaps ’. PARATYPE: 1 ♀, same label data as holotype ( NMPC).

Description. Male holotype. Body length 2.8 mm. Brownish, opaque, antennae and tarsi honey-red, tibiae dark ferruginous. Semierect silvery setae are on internal margin of tibiae at apical fifth, and some similar ones can be seen on underside of apex of rostrum. Very thin slightly erect golden setae are very sparse on ventrites ( Figs 16 and 17 View Figs 16–21. 16–17, 19 ).

Head. Rostrum 1.94 times longer than wide at its widest point and 0.59 times as long as pronotum, slightly dilated at base, moderately curved and slightly tapering towards apex in lateral view, dorsum longitudinally and irregularly strigose up to antennal insertion, then microreticulate. Scrobes large, rather deep, smooth, and reaching base of head below eyes. Antennae inserted on apical quarter of rostrum. Head strigose like dorsum of rostrum.

Pronotum 1.08 times longer than wide, strongly constricted at apex as to appear collar-shaped, disc rather flat, with large coarse roundish punctures, sides almost parallel sided in middle and moderately curved towards apical constriction and towards base, widest basad of middle.

Elytra 1.78 times longer than wide, maximum width at middle. Striae formed by very large deep subrectangularly elongate punctures. Intervals in form of low narrow keels with a series of comparatively large granules in posterior third.

Legs. Femora relatively elongate, upper margin more strongly curved than lower one; tibiae both longitudinally and transversally slightly bisinuous, internal margin of protibiae with setose concavity at their apical third, that of meso- and metatibiae less pronounced, at apex with stout internal mucro besides strong external uncus.

Ventral side with large round deep coarse punctures, these much finer and irregular on ventrites III to V. Ventrites I and II with large shallow common depression.

Male genitalia. Aedeagus as depicted in Fig. 19 View Figs 16–21. 16–17, 19 .

Variability. The female is very similar to the holotype, apart from the lack of ventral depression. Body length 2.7 mm.

Differential diagnosis. Quite similar to Hajekia parvopunctata sp. nov. and H. opaca sp. nov., the descriptions of which follow, yet easily recognizable by its larger size, rostrum elongate and moderately dilated towards apex, much larger punctures on pronotum, elytral striae formed by large subrectangular punctures, and intervals with rather large granules. According to the description, possibly also Dryotribus breviceps Marshall, 1925 from Indonesia may belong to this or to a close new genus, although it is easily distinguished from the Socotran species by the antennae inserted just apicad of middle instead at apical quarter of rostrum, the greater distance of eyes from the anterior margin of pronotum, and the elytra widening towards apex.

Etymology. The species takes its name by the combination of the Greek nouns ‘μικρός’ (small) and ‘ὤψ’ (eye) in reference to its most salient feature; noun in apposition.

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.
