Habitus as in Figs. 109–110 ; body length of holotype 5.2 mm , of paratypes 5.1–6.3 mm (JJ), 5.1–7.1 mm ( ♀♀ ). Body dark brown to black; head, pronotum and elytra brown, usually with feeble metallic bronze reflections which are sometimes more evident, head and pronotum darker; labrum and palpi reddish; antennae reddish at base, usually darkened starting from antennomere V or VI; mandibles dark brown to black; legs dark brown. Frons weakly convex, with confuse punctures and relatively long silvery pubescence; clypeus not divided from frons, with finer and more spaced punctures and shorter pubescence. Antennomere I one fourth longer than antennomere II and nearly twice as wide; antennomere II 2.5 times longer than wide, feebly bent; antennomere III one third longer than antennomere II; antennomeres IV and V slightly shorter than antennomere III and longer than antennomere VI; antennomeres VII–X feebly widened, antennomere VII slightly longer than the following ones; antennomeres VI–X 1.6–1.7 times longer than wide; antennomere XI nearly 2.5 times longer than wide. Pronotum 1.6–1.7 ( JJ ), 1.7–1.8 ( ♀♀ ) times wider than long (2.4 × 1.4 mm in holotype ), at base nearly as wide as or little wider than at distal border ; sides regularly arched and margined throughout, widest in middle; surface densely punctate, sometimes with longitudinal not punctured short stripe on disc; surface between punctures smooth and shiny, narrower than diameter of punctures; pubescence moderately long, fine, silvery, in large part recumbent. Scutellum wider than long, rounded distally ( Fig. 14 ), pubescent. Hypomeron punctured throughout, with moderately long pubescence; prosternum with moderately long pubescence; mesepimera bare, not punctured; metanepisterna five times longer than wide, with short pubescence. Elytra oblong, 1.3 times longer than wide at humeri (3.6 × 2.7 mm in holotype ), feebly impressed dorsally in basal fifth; sides subparallel in basal half (J) or feebly widened toward rear till three fourths of their length ( ♀ ), then regularly curved to elytral apices, which are in right angle; humeri weakly prominent; punctation slightly finer than on pronotum, irregular, finer on apical slope; pubescence shorter than on pronotum, fine, suberect. Epipleura gradually tapering toward rear, reaching elytral apices. Legs moderately long; femora with very small median tooth, sometimes unarmed, moderately swollen; tibiae nearly straight, sometimes protibiae feebly bent; pro– and mesotarsomere I feebly widened in J. Claws bifid, starting from their midlength, with short internal tooth. Abdomen dorsally poorly sclerotized, with exception of last visible segment. Aedeagus as in Figs. 8–9 . Spermatheca as in Fig. 12 ; coxites ( Fig. 13 ) moderately sclerotized in their distal portion, spiculum ventrale moderately long and thin, vagina without any sclerotization. Variability. Some examined specimens ( Socotra : Gabbach di-Net and Sharet Halma vill.) show a shorter and more recumbent dorsal pubescence and shorter antennomeres, although other characteristics (genitalia included) perfectly match with those of specimens from other localities. Differential diagnosis. Colasposoma ( Falsonerissus ) grande insulare subsp. nov. is characterized by shorter antennomeres VII–XI (twice longer than wide in C. ( F. ) grande grande ), stronger punctation of the pronotum, elytral sides subparallel in the proximal half (feebly widened toward rear in the basal half in C. ( F. ) grande grande ) and apex of aedeagus more elongated ( Figs. 8–9, 15–16 ). Etymology. The name underlines the differentiation of the population of Socotra from the nominal form in Yemen mainland.
