PARATYPES : 1 ♀ , same label data as holotype ( NMPC ) ; 4 JJ 5 ♀♀ , ‘ Yemen , Socotra Island // Bizidig // Avicennia marina mangrove,// 13.vi.2012 // 12°18.6′N , 53°48.2′E , 6 m’, ‘Socotra expedition 2012 // J. Bezděk , J. Hájek , V. Hula , // P. Kment , I. Malenovský , // J. Niedobová & L. Purchart leg.’ (6 NMPC , 1 BMNH , 2 ECRI ) . Description. Female holotype . Body length 1.8 mm . Piceous, antennae and tarsi ferruginous, tibiae dark ferruginous. Semierect whitish capitate hair-like whitish scales pointing forward are on rostrum, head and pronotum, whereas similar ones arranged in row on each of elytral intervals being almost perpendicular, longer, and pointed backward. Ventral side with sparse almost recumbent silvery setae ( Fig. 31 ). Head. Rostrum 1.90 times longer than wide at its widest point and 0.63 times as long as pronotum, slightly dilated at antennal insertion, curved and slightly widening towards apex in lateral view, dorsum microreticulate and barely convex. Scrobes rather thin and deep, little exceeding base of head below eyes. Antennae inserted at middle of rostrum. Head measured from base to anterior margin of eyes as long as rostrum. Pronotum 1.07 times longer than wide, strongly constricted at apex as to appear collar-shaped, widest basad of middle; disc rather flat, microreticulate and with rather sparse roundish punctures, sides slightly sinuous in middle and moderately curved towards apical constriction and towards base. Elytra 1.97 times longer than wide and just 1.10 times as wide as pronotum, sides almost parallel, maximum width at middle. Striae formed by rather large deep subrectangular punctures. Intervals quite smooth and slightly convex. Legs. Femora relatively elongate, dorsal margin quite strongly curved; tibiae curved at base, then slightly widening towards apex. Ventral side , except prosternum and ventrites III and IV, with rather large moderately dense roundish punctures, rest of surface quite shining. Variability. Males are very similar to the holotype , differing only by their rostrum being slightly thicker, and the metaventrite and basal abdominal ventrites quite flat. Females are almost identical to the holotype . Male genitalia. Aedeagus as depicted in Fig. 34 . Body length 1.8–2.1 mm . Etymology. The species name, the Latin adjective barbatus (- a , - um ) meaning bearded, is given in reference to the erect hair-like scales on the whole dorsal surface. Collection circumstances. Specimens from Bizidig were sifted from decaying leaves on sand under an isolated stand of mangrove Avicennia marina (Forssk.) Vierh. (Acanthaceae) (J. Hájek, pers. comm.). Distribution. Endemic to Socotra Island .
