Description. Male holotype. Colouration. Head brown, mandibles, labrum and clypeus more testaceous, mandibles with dark tip. Antennomeres I–III and basal third of IV yellowish brown, rest of antennae reddish brown. Maxillary and labial palpi yellowish red. Underside of head red. Pronotum red with lateral margins and posterior angles somewhat lighter. Elytra dull brown, except scutellum and lateral margin which are testaceous. Epipleura, meso- and metaventrite and abdominal ventrite I testaceous, rest of abdomen black. Underside reddish, except for brown epipleura and abdominal ventrites II–VI. Legs yellowish red.

Sculptures and structures. Head. Vertex heavily wrinkled and punctured, microsculpture isodiametric, suppressed. Two supraocular setae. Temples very short and almost perpendicular to neck. Eyes almost hemispherical. Labrum transverse with six setae frontally; microsculpture isodiametric laterally, meshes more transverse medially; anterior margin almost straight. Clypeus with anterior margin very slightly incurved, with two setae; posterior margin slightly convex, with isodiametric microsculpture; on disc convex, with shallow impression near base medially and flattened towards anterior angles. Base longitudinally wrinkled, punctured and with isodiametric microsculpture. Antennomeres I–III and basal third of IV glabrous, rest of antennae pubescent.Antennae slender: antennomere V 3.3 times longer than wide. Maxillary palpi with some tiny setae on terminal, fusiform, oblique truncate palpomeres. Labial palpomere I with two large setae and a few smaller ones on its inner side. Mentum with simple median tooth, epilobes separated from mentum by suture. Head width 1.6 mm.

Pronotum transverse, 1.4 times as wide as long. Anterior angles completely rounded. Surface of disc heavily wrinkled with more or less suppressed isodiametric microsculpture, except along anterior margin and on lobes, latter with microsculpture more distinct. Lobe slightly and gradually protruding. Pronotum on base and anterior margin beaded, sides rather flat, slightly bent upwards near posterior angles; basal grooves shallow. Median line thin, impunctate. Pronotum with two setae on each side, first in about one fourth of length and at distance of diameter of puncture away from lateral margin; second one in posterior angle. Basal furrow rather deep, uninterrupted by median line. Median line fine, beginning at about width of antennomere V from apical margin, and attaining basal furrow. Lateral margin very narrow at apex, gradually becoming wider until about half of length of pronotum, then suddenly becoming much wider towards very shallow basal impressions ( Fig. 4 ). Anterior border of pronotum much narrower than base, sides at apex very strongly and regularly curved, from middle onwards almost straight or very weakly sinuate towards posterior angles ( Fig. 4 ). Prosternal process without raised side border and tip dorsally bent, without setae, brown. Middle part of prosternum towards prosternal process very convex with sparse setae.

Elytra wide. Striae finely punctured, intervals somewhat convex at base, becoming flatter towards apex. Inner intervals at apex flat, outer ones very slightly convex. Intervals with strong isodiametric microsculpture and small shallow punctures. Basal margin complete, almost continuing into long scutellar stria; scutellar pores present. Humeri prominent. Apex of elytra hardly sinuate, obliquely truncated in almost straight line. Interval III with two setae, first at almost same distance from base as second from apex. First pore touching stria III, second near or touching stria III. Row of setiferous punctures in elytral stria VIII with 15 pores, first five (posthumeral pores) and last five (preapical pores) closer together than the middle ones. Last pore in middle of interval IX, 14 th nearer stria VIII and 13 th nearer stria IX. Stria VII almost reaching stria I at apex, broken up into punctures apically, with two setae at apex of intervals II and III ( Fig. 7 ). Epipleura smooth with some deep irregular grooves ( Fig. 2 ).

Ventrites with sparse and long pubescence. Pro- and mesepisterna somewhat rugose, with some erect short setae. Male apical abdominal ventrite without small incision.

Tarsi rather stout, metatarsomere III about two times longer than wide. Incision of metatarsomere IV reaches one third of tarsomere length. Claws pectinate with six teeth. Male with three blunt protruding teeth on inner apex of mesotibia; inner side of apex prominently protruding outwards.

Aedeagus with median lobe short, rather bulky and broad, with large apical opening, asymmetrical, apex slightly pointing to left and tip strongly pointed downwards. Internal sac with five clusters of larger and finer teeth and large oval reticulated body, flanked on each side by pointed more or less scaly lobes ( Fig. 8 ). Genital segment as in Fig. 10 .

Female. Stylomeres 1 and 2 as in Fig. 9

Variability. All specimens of the type series agree with the holotype in all aspects, except for measurements: body length 5.0– 7.4 mm, (holotype 6.5 mm; mean value 5.9 mm); females on average slightly larger than males. Antennomere V 2.7 –4.0 times longer than wide (mean value 3.2). Head width 1.2–1.6 mm (mean value 1.4 mm). Pronotum 1.4–1.5 times as wide as long .

Etymology. The specific epithet refers to the presence of the species in the island of Socotra; adjective.

Collection circumstances. Most specimens of the new species were attracted to light trap (J. Hájek, pers. comm.).
