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

Head about 7/10 as long as distance between eyes, subdepressed and with slightly raised temples; eyes composed of moderately small facets. Frons and labrum: (Fig. 2). Antennae slightly shorter than head width, their club (Fig. 3) about 1.5 times as long as wide, composing about 1/4 total antennái length, antennomere 2 slightly shorter than antennomere 4 and slightly longer than antennomere 3. Pronotum weakly convex at disk and widely subexplanate at sides (as widely subexplanate as width of antennái club). Scutellum subtriangular with narrowly rounded apex. Elytra about 8/9 times as long as their combined width; widely subexplanate at edges (as widely subexplanate as pronotal sides), apices transversely truncate. Tergite VI mostly exposed from under elytral apices. Pygidium with sharply truncate apex. Antennái grooves steeply convergent behind mentum with distinct expressed inner edges, but without trace of outer edges. Mentum subhexogonal and about 2-5 times as wide as long. Last labial palpomere somewhat widened apically and slightly longer than wide (Fig. 4). Prosternai process slightly curved along coxae before its subcarinate apex with subsemicircular posterior edge, which slightly wider than antenna! club (Figs 5-6). Distance between mesocoxae about 1.5 times and that between metacoxae nearly twice as broad as that between procoxae. Metasternum subflattened, with a medial suture in distal half before its posterior edge, which is feebly angularly excised between metacoxae. Ventrite 1 considerably shorter than hypopygidium, the latter with rather projecting and widely rounded to subtruncate apex. Epipleura about 3 times as wide as antennái club. Legs rather narrow and long. Protibia (Fig. 7) somewhat curved before the middle and widened at apex, where it is 3/4 as wide as antennái club, its spurs very short. Mesotibia curved and widened at base, but in distal half subparallel-sided and about as wide as protibia at apex. Metatibia very narrow, parallel-sided and rather long (about as long as metafemur), about 1/2 as wide as antennái club. Both meso- (Fig. 8) and metatibiae (Fig. 9) with rows of rather short setae along outer edge and moderate spurs. Pro- and mesofemora more than 2.5 times, but metafemur nearly 4 times as wide as corresponding tibia; posterior edges of meso- and metafemora almost straight. Protarsus nearly as wide as corresponding tibia, mesotarsus somewhat narrower and metatarsus much narrower; tarsomere 5 much longer than 1-4 combined, claws narrow and very long. Aedeagus weakly sclerotized (Figs 10-11). Variability - Length 4.2, width 2.2 mm. The paratype differs from holotype in the much more conspicuous pubescence, protibiae and mesotibiae gently curved at base, metatibia somewhat shorter and somewhat less narrow. Diagnosis - Many characters of this new species are quite typical to members of the subgenus Epuraea s. str. However, some of characters are unusual or more characteristic to other subgenera. The subflattened body with depressed head and widely explanate pronotal and elytral sides of the new species make its position out of all known groups among not only the subgenus Epuraea, but among the tribe Epurainae as a whole. The last labial palpomere of it is rather short and widened apically, which is more characteristic of that in the subgenera Haptoncus MURRAY, 1864 and Haptoncurina JELÍNEK, 1978 than of the members of the subgenus Epuraea s. str. The pygidium with sharply truncate apex of the considered new species is also more characteristic of other subgenera than Epuraea s. str. Nevertheless, it should be rather regarded as a member of Epuraea s. str. than other subgenera because of its small eye facets. Etymology - The name of this new species is formed from the Latin "super" (over, above) and "latus" (wide, broad).
