Description. Body length/width: males 1.3–1.6/ 0.8–0.9 mm (holotype 1.5/ 0.9 mm); females 1.4–1.6/0.8–1.0 mm.

Male (holotype). Black, lustrous, maxillar palpi yellow, antennae yellow with apex of antennomere XI darkened ( Fig. 31 ). Legs with coxae and femora black (except yellow apices of pro- and mesofemora), trochanters brownish, tibiae and tarsi yellow.

Head ( Fig. 13 ) small. Anterior part of head smooth. Antennal calli small, trigonate-oval, shining and roundabout well delimited by impressions. Frontal lines nearly straight, deeply incised. Vertex smooth with several fine and scattered punctures above frontal lines, near the upper margin of each eye with two or three pores bearing pale seta. Ratio of distances between inner and outer margins of eyes 1:2.3. Antennae short, thin, 0.5 times as long as body, proportions of antennomeres are 8:5:6:4:7:6:8:8:9:8:11 (1 = 0.01 mm).All antennomeres bearing long setae apically.

Pronotum 1.60 times as wide as long, widest in middle, moderately convex. Anterior margin nearly straight, lateral margins moderately rounded, anteriorly convergent. Anterior and posterior margins finely bordered, lateral margins narrowly and sharply bordered. Anterior angles shortly and obliquely truncate but not edged posteriorly, posterior corners rounded, with setigerous pore. Surface densely covered with large punctures but smaller than on elytra.

Scutellum small, almost semicircular. Elytra glabrous, oval, 0.65 times as long as body, 1.10 times as long as wide. Surface with 11 regular striae of large punctures, well visible also on apex, scutellar row exceeding mid of elytra, distance between punctures ca. twice longer than their diameter; interstices plain and smooth. Humeral calli small but well developed.

Prosternal process as wide as antennomere II, longitudinally sulcated, with posterior part somewhat broadened, densely punctured. Metaventrite and abdomen covered with fine scattered punctures bearing fine grey setae. Ventrite I as long as following ones combined. Apical ventrite with two small triangular incisions on posterior margin.

Protarsomere I slightly dilated, with rounded sides, subtriangular, as wide as protarsomere III, length ratios of protarsomeres I–IV equal to 4-3-4-6. Metatibiae straight, with dorsal side slightly convex, in apical third more or less even and on both sides provided with row of fine setae, terminated with short simple spur inserted in middle of apex. Metatarsomere I shorter than half of metatibia length, metatarsomere III bilobed. Length ratios of metatarsomeres I–IV equal to 7-4-4-6.

Aedeagus narrowed in middle part, moderately bent in lateral view, ventrally with large spoon-shaped impression ( Fig. 3 ).

Female. Protarsomere I narrower than in male, with sides straight, narrower than protarsomere III. Apical ventrite evenly rounded. Spermatheca ( Fig. 17 ): nodulus elongate, posteriorly narrowed, cornu thin, in first third bent in angle ca 45°.

Differential diagnosis. See description of the genus.

Etymology. Named after its patria, Socotra Island.

Distribution. Yemen: Socotra Island
