Epuraea (Micruria) spiculata sp. n. (Figs 12-22) Description of male (holotype) - Length 4.0, width 1

.9, height 1.0 mm. Rather convex dorsally and slightly convex ventrally (Fig. 12); dorsum dark brownish, underside and appendages more or less lighter (appendages nearly reddish); dorsum and underside with a faint copper lustre; dorsum with conspicuous yellowish golden hairs, more or less longer than distance between their insertions; underside with sparser and less conspicuous hairs. Head and pronotum microgranulose (behind each tubercle a more or less expressed small puncture is disposed), finely and cellularly microreticulated. Elytral with punctures, somewhat smaller than eye facets in diameter; interspaces between them 4-5 times broader than a puncture diameter and with relief cellular microreticulation. Pygidium and ventites nearly as punctured and sculptured as elytra, but punctures smaller and sparser, interspaces between them less relief. Prosternum extremely finely and very sparsely punctured, very finely and very densely microreticulated. Middle of metasternum indistinctly punctured and with sclerites and interspaces densely microreticulated. Head about 6/7 as long as distance between eyes, shallowly concave behind antennái insertions; eyes moderately faceted. Exposed part of labral lobes about 2/5 as long as width of their combined base (Fig. 13). Antennae markedly shorter than head width, club (Fig. 14) subovoid, about 1 and 1/3 as long as wide, composing about 2/7 of total antennái length. Pronotum and elytra strongly vaulted, sides steeply sloping (elytra subvertical) and unexplanate, elytral apices transversely subtruncate; elytra about as long as wide combined. Pygidium rounded at apex, under which only a widely rounded apex of anal sclerite is narrowly exposed. Last labial palpomere (Fig. 15) subparallel-sided and about 1.5 times as long as wide. Mentum subquadrangular with somewhat arcuate sides, about twice as wide as long. Prosternai process (Fig. 16) strongly curved along coxae and its transverse apex approaching the rather excavate surface of mesosternum, its very widely rounded apex about 1.5 times as antennái club. Distance between mesocoxae subequal to and that between metacoxae about 3 times broader than that between mesocoxae. Mesosternum without any developed medial carina. Metasternum flattened and with a narrow median and depressed stripe in distal half, before its posterior edge which is arcuately emarginate between coxae. Epipleura somewhat wider than antennái club. All tibiae moderately wide, about as wide as antennái club, and with very short spurs; protibia (Fig. 17) with very prominent subapical process, which about half of most width of protibia and strongly curved ventrally; meso- (Fig. 18) and metatibiae with rows of short, rather stout and very sparse spines. Femora with gently outlined and convex both anterior and posterior edges, pro- and metafemora about twice as wide as corresponding tibiae, mesofemur somewhat narrower. Protarsus about 5/6 as wide as corresponding tibiae, meso- and metatarsi much narrower; claws strongly toothed at base. Ventral plate and spiculum gastrale: Fig. 19. Aedeagus moderately sclerotized (Figs 20-21). Female - Differs from male only in slightly narrower protibia and protarsus, smallewr ultimate antennomere, somewhat extended and narrowly subtruncate pygidial apex. Ovipositor (Fig. 22) with sclerites of usual configuration, comparatively short and weakly sclerotized. Variability - Length 3.0^4.0 mm. All females examined have head and pronotum punctured, but not microgranulose, with punctures, as large as eye facets in diameter, interspaces between them more or less narrower than a puncture diameter. The last labial palpomere in some paratypes is only slightly longer than wide.
