Hagherius sculptus sp. nov.

( Figs 136–138 )

Type material. HOLOTYPE: J ( NMPC), ‘ Yemen, Socotra Island // Hagher Mts. , Scand Mt. env. // montane evergreen woodland // 16–18.vi.2012 // 12°34.6′N E 54°01.5′E, 1450 m’, ‘Socotra expedition 2012 // J. Bezděk, J. Hájek, V. Hula, // P. Kment, I. Malenovský, // J. Niedobová & L. Purchart leg. ’. PARATYPES: 3 ♀♀, same label data as holotype (2 NMPC, 1 ECRI).

Description. Male holotype. Body length 2.8 mm. Piceous, shining, rostrum, legs and antennae brown, apical antennomere (club excepted) little paler. Dorsal vestiture composed of rather sparse half-recumbent golden-brownish hair-like scales longer and arranged in two irregular rows on elytral intervals. Ventral side rather densely and coarsely punctured with fairly sparse rather short almost recumbent golden setae.

Head. Rostrum 0.90 as pronotum, moderately curved, somewhat compressed on basal 3/4 and here with punctures forming 2–3 irregular lateral striae, in dorsal view widening at apical third where rostrum slightly compressed and finely punctured, apical fifth bearing some erect fairly long setae. Antennae inserted at apical quarter of rostrum; scape almost straight and quite abruptly clubbed, its anterior margin bearing three long erect setae near apex; funicular antennomere I thicker and slightly longer than second, latter slightly less than twice as long as wide; antennomeres III to VII moniliform and progressively slightly shorter, apical three moderately transverse; club fusiform and slightly longer than three preceding antennomeres. Head globular, minutely punctured; eyes dorsal, elliptical, almost flat, slightly sunken, and subcontiguous at middle.

Pronotum 0.83 times as long as wide, rather strongly constricted towards apical and basal margins, apex truncate, base slightly bisinuous; disc quite flat and barely depressed in front of scutellar area, and here bearing some centripetal whitish recumbent setae longer that sparse erect ones of rest of surface; sides rather strongly rounded, maximum width at middle. Scutellum minute.

Elytra 1.20 times as long as wide and twice as long as pronotum, dorsum flat only near scutellum, then moderately convex, base slightly concave, sides moderately curved on basal two thirds then quite abruptly converging towards acute apex, maximum width at middle. Striae sulciform, deep, and with catenulate punctures at bottom. Interstriae almost flat, slightly wider than striae, with small irregular punctures.

Legs quite short, particularly middle and posterior ones; femora strongly clubbed, anterior ones more strongly and acutely toothed than middle and posterior ones, alutaceous and with almost recumbent long setae; tibiae slightly compressed, curved at base then almost straight, alutaceous, inner and outer margin bearing semierect setae; tarsi short, rather narrow, tarsomere III slightly bilobed.

Ventral side. Abdominal ventrites I and II slightly depressed together.

Male genitalia. Aedeagus as depicted in Fig. 137 .

Variability. Females are very similar to the holotype, differing from it by their slightly more convex elytra and lack of abdominal depression ( Fig. 136 ).

Female genitalia. Spermatheca as depicted in Fig. 138 .

Body length 2.6–2.9 mm.

Etymology. The species name, the Latin adjective sculptus (- a, - um), meaning ‘engraved’, is in reference to the strongly punctured pronotum and deep elytral striae of the new species.

Distribution. Endemic to Socotra Island.
