Bezdekiellus lucidulus sp. nov.

( Figs 30, 33 )

Type material. HOLOTYPE: J ( NMPC), ‘ 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.’. PARATYPES: 4 JJ 4 ♀♀, same label data as holotype (4 NMPC, 1 BMNH, 3 ECRI); 2 JJ 2 ♀♀, ‘ 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. Bezděk, J. Hájek, V. Hula, // P. Kment, I. Malenovský, // J. Niedobová & L. Purchart leg.’ ( NMPC).

Description. Male holotype. Body length 1.9 mm. Shining, dark ferruginous, antennae and tarsi slightly paler ( Fig. 30 ).

Head. Rostrum 1.64 times as long as wide at its widest point and 0.51 as long as pronotum, irregularly striolate on dorsum. Scrobes thin and deep, curving downward to reach just basad of middle of rostrum, their apical third visible from above. Head globular, short, impunctate.

Pronotum 1.18 times longer than wide, widest at basal quarter, moderately constricted at apex, quite abruptly so towards base; disc moderately convex, with large roundish dense punctures, sides subparallel in middle, moderately curved towards apical constriction and quite strongly rounded towards base.

Elytra 2.02 times longer than wide and 0.94 times narrower than pronotum, sides almost parallel, maximum width at apical quarter. Striae formed by rather large deep round punctures. Intervals narrower than striae, micropunctulate and slightly convex.

Ventral side with large round punctures, metaventrite, abdominal ventrites I and II with large common depression.

Variability. Aside from cuticle colour more or less dark, paratypes are almost identical to the holotype. The rostrum of females is little longer and thinner, and they lack abdominal depression.

Male genitalia. Aedeagus as depicted in Fig. 33 .

Body length 1.9–2.0 mm.

Etymology. Also this species is named after the glossy surface of its integument, and the name additionally points to its similarity with Hajekia lucida sp. nov.; adjective ( lucidulus , - a, - um). Collection circumstances. Sifted from leaf litter under Ficus vasta Forssk. (Moraceae) in karstic terrain (J. Hájek pers. comm.).

Distribution. Endemic to Socotra Island.
