Click beetles of Taiwan collected by the expeditions of HNHM (Coleoptera: Elateridae) 69Podeonius csorbai sp. n.(Figs 23–24)Material examined – Holotype female: Taiwan: Ilan County, Mingchyh Forest RecreationArea, 1200 m, at light, 5.IV.2002, GY. FÁBIÁN &O.MERKL (HNHM). – 1 Paratype female:Nantou County, Kao-Leng Dyi, 18 km W of Wushe, 24°4.605’N, 121°7.583’E, 2074 m,from tree trunks at night, 18–19.IV.2002, D. A. ANSTINE, GY. FÁBIÁN & O. MERKL (CPG).Description – Female. Moderately shiny; entirely black except for antennae and legs, basalmargin of pronotum, elytra and central disk of scutellum reddish (holotype) or only antenna, legsand scutellum lighter (paratype); covered with long, dense, recumbent, fulvous vestiture (Fig. 23).Frons convex, flat only at anterior margin, the latter well defined (paratype) to obsolete(holotype), in the middle nearly touching the inferior part of clypeus; puncture very close andumbilicate on all the surface. Antennae (Fig. 24) exceeding by about one antennomere the apicesof posterior angles of pronotum, feebly serrate from fourth antennomere; second antennomereas long as broad; third a little longer than second and nearly twice longer than broad;second and third, taken together as long as fourth; fourth to tenth triangular, fourth longer thanfollowing and twice longer than broad, the remaining antennomeres shorter; last antennomerea little longer than penultimate, subellipsoidal. Pronotum 1.1 times broader than long, widest atposterior angles, strongly convex, abruptly sloping at sides and base, here with a trace of short,midlongitudinal furrow in the declivity; sides regularly and rather strongly narrowing from baseto apex; hind angles elongate, acute, not divergent at apex, bicarinate; inner carina more prominentand directed inside; outer carina shallow and subparallel to lateral margins; punctures coarseand dense on all the surface, on the disk punctures umbilicate with shortest and slightlyshagreened interspaces; gradually coarser at sides, with shortest, more shagreened interspaces tocontiguous and subrugose at lateral extremity. Scutellum tongue-shaped, moderately convex,roughly punctured. Elytra as broad as pronotum at base, 2.8–2.9 times longer than the latter; sidessubparallel in the first half then gradually tapering towards apex; striae well marked and punctured;interstriae with rugose surface. Third tarsomere with long lamella beneath. Prosternal processbriefly and nearly vertically bent in the basal part, then running horizontally and emarginateat apex. Size. Length 8.4 (holotype)–8,7 mm; width 2.3 (holotype)–2.5 mm.Male unknown.Etymology – This species is dedicated to Dr. GÁBOR CSORBA (HNHM), mammalogist,studying taxonomy and biogeography of Chiroptera, collector of valuable beetle materialsfrom various Southeast Asian countries, including Taiwan.Comparative remarks – It is separated from the known species of Taiwanby the elongate general outline, the coarse and dense punctation of pronotumgiving a dull appearance to the surface.Annls hist.-nat.
