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

emarginate before median movable lobe. Apex of last abdominal segment: Fig. 90. Ventral plate and spiculum gastrale: Fig 83. Tegmen well sclerotized (Figs 84-86). Diagnosis - The shape of sclerites of the last abdominal segment of this new species is somewhat similar to that of A. lewisi REITTER, 1873, but its male genitalia are similar to those in A. japonicus and A. opacus (MOTSCHULSKY, 1863). However, in contrast to all of them the new species has widely rounded elytral apices. It differs from the former in the somewhat smaller and more robust body, oblique posterior edge of pronotum at posterior angles, markedly finer puncturation of dorsum, wider antennái club, shorter last labial palpomere, sharply carinate prosternum, not flattened and narrower prosternai process, much shorter and wider median plate of mesosternum, shallower excision of posterior edge of hypopygidium and significantly shorter movable median lobe. This new species differs from both A. japonicus and A. opacus in the finer and denser puncturation, shorter cilia along pronotal and elytral sides, longer antennomere 4 (in A. japonicus and A. opacus it is only about half as long as antennomere 3), markedly shorter median plate of mesosternum and lack of median process at the bottom of apical excision of hypopygidium. The short cilia along the pronotal and elytral sides are quite unique among species of Amphicrossus with paramedial brushes of long hairs on the male elytra. Etymology - The name of this new species is devoted to A. MURRAY, who published one of the best monographs on the systematics of the family Nitidulidae (MURRAY 1864) with description of many genera and species. Amphicrossus opinatus sp. n. (Figs 91-100) Specimens examined - (In addition to the holotype from Taiwan, see above.)."Laos, Louangnamtha pr., 21°09'N, 101°19'E, Nantha, Muang Sing, 5-31.V.1997, 900-1200 m, Vit Kubán" (4 paratypes, NMB, ZISP); "Tarn Dao, 20-26.6.1990, N. Vietnam, A. Olexa" (4 paratypes, NMB, ZISP). Description of male ( holotype) - This new species is rather similar to A. angusticlavis sp. n., so some characters shared by both species are omitted in the below description.Length 6.0, width 3.8, height 1.9 mm. Moderately convex dorsally and slightly ventrally; dorsum subunicolorous (chestnut) reddish brown; underside and appendages lighter to bright reddish with darkened antennái club; dorsum with a faint shine, and underside moderately shining; body with moderately conspicuous fine golden yellowish hairs, about 3-4 times as long as distance between their insertions (on underside pubescence somewhat shorter) and dorsum also with sparser and much longer reddish hairs (darker than shorter ones); pronotal and elytral sides with dense cilia, consisting of hairs about as long as tarsal
