Kirejsthuk, A. G.: On the fauna of Nitidulidae (Insecta, Coleoptera) from Taiwan with some taxonomical notes

along the middle of each elytron); dorsum with a very faint shine, and underside moderately shining; body with strongly conspicuous fine golden hairs, more than 4-5 times as long as distance between their insertions and dorsum also with sparser and much longer hairs; pronotal and elytral sides with dense cilia, consisting of hairs about as long as tarsal claws; paramedial brushes of long hairs situated at anterior 1/3 (these hairs about twice as long as hairs in cilia) (Fig. 109). Head with distinct punctures, about as large as eye facets, interspaces between them a little narrower than a puncture diameter and rather smoothed. Pronotum and elytra with distinct punctures, slightly smaller than eye facets, interspaces between them somewhat broader than a puncture diameter, densely and cellularly microreticulated (on subsutural places in anterior part of elytra puncturation becoming shallower and less distinct). Prosternum with obsolete puncturation and smoothed sculpture, but its process with distinct and sparse small punctures, interspaces between them smooth. Metasternum with distinct and moderately dense punctures, somewhat smaller than eye facets in diameter, interspaces between them about 2 puncture diameters and rather smoothly microreticulated. Ventrites finely and very densely microgranulose. Antennái club (Fig. 110) comprising about 2/7 of total antennái length, slightly longer than wide, antennomere 3 nearly as long as antennomere 2 and slightly longer than antennomere 4. Pronotum with posterior edge rather oblique at posterior angles. Elytra about 4/5 as long as broad combined, their apices suboblique (their outer subapical angles more projecting posteriorly than inner subapical ones). Pygidium very widely rounded to subtruncate at apex. Mentum subquadrangular, more than 3 times as wide as long. Prosternum sharply carinate, but its process ( Fig. Ill) flattened and rather widened at very widely rounded to subtruncate posterior edge. Median plate of mesosternum (Fig. 112) about 2.5 times as wide as long, its posterior edge nearly straight. Metasternum subflattened in the middle. Hypopygidium rather deeply and regularly emarginate before median movable lobe and with a distinct narrow process bearing a brush of very short and dense setae at bottom of this emargination (Fig. 114). Apex of last abdominal segment: Fig. 113. Ventral plate and spiculum gastrale: Fig 115. Tegmen moderately sclerotized (Figs 116-118). Diagnosis - This new species differs from all other congeners in its suboblique elytral apices forming a widely opened suturai angle. It has many of characters similar to those in A. lobanovi sp. n. and A. oblongus, although it differs from them in the smaller body, wider and subcircular antennái club, wider prosternal process with subtruncate apex, longer median plate of the mesosternum and distinct male genital structures. Etymology - The Latin name of this new species means "foggy", "cloudy" and "misty". Figs 119-139.119-129.
