Hajekia lucida sp. nov.

( Figs 27, 28 )

Type material. HOLOTYPE: J ( NMPC), ‘ Yemen, Socotra island // wadi Thar di Itrur , 21.vi.2012 // sifting under Ficus cordata // 12°32.8′N, 53°42.9′E, 54 m’, ‘ Socotra expedition 2012 // J. Bezděk, J. Hájek, V. Hula, // P. Kment, I. Malenovský, // J. Niedobová & L. Purchart leg. ’. PARATYPES: 1 J 1 ♀, same label data as holotype (1 NMPC, 1 ECRI).

Description. Male holotype. Body length 2.4 mm. Pitchy-brown, bare, head and pronotum alutaceous, elytra shining, antennae and legs dark ferruginous ( Fig. 27 ).

Head. Rostrum 1.60 times longer than wide at its widest point and 0.60 times as long as pronotum, strongly curved at middle and weekly tapering at apical quarter in lateral view, dorsum with thin dense faintly strigose punctures. Scrobes rather thin, deep, smooth, and reaching basally middle of rostrum below. Antennae inserted at base of apical quarter of rostrum. Scape thin, moderately clubbed on apical third; funicular antennomere I thicker than others and twice as long as wide, antennomere II one and half times longer than wide; antennomeres III to V about as long as wide; club oval, setose, as long as three preceding antennomeres.

Pronotum 1.05 times as long as wide, widest at middle; disc rather flat, with fairly large dense roundish punctures, sides regularly curved towards apical constriction and towards base, apex slightly concave, base almost straight.

Elytra 1.78 times longer than wide, subparallel sided, maximum width at middle. Striae formed by quite large deep round punctures. Intervals flat and barely wider than striae.

Legs similar to those of other species of the genus.

Ventral side with rather large, not very dense punctures, except on ventrites III to V. Metaventrite and abdominal ventrite I with large common central depression.

Variability. The other male is very similar to the holotype, whereas the female differs by its rostrum slightly longer and thinner and abdomen with no impressions.

Male genitalia. Aedeagus as depicted in Fig. 28 .

Body length 2.3–2.4 mm.

Differential diagnosis. The shining dorsal surface makes this species unmistakable among its congeners.

Etymology. The species name, Latin adjective lucidus (- a, - um), meaning bright, shining, or light, is given for the glossy surface of its integument.

Collection circumstances. Sifted from leaf litter under Ficus cordata Thunb. (Moraceae) (J. Hájek, pers. comm.).

Distribution. Endemic to Socotra Island.
