Frischianus curtipennis Frisch, sp. nov. (Figs 47, 257) Type specimens: Holotype ♀, Indonesia, Jambi, Kerinci: Mt Kerinci, 1900 m, 13.XI.1989, leg. Agosti, Burckhardt & Löbl (MHNG). Description: Habitus (Fig. 47). Similar to Frischianus subalpinus from which it differs as follows: Body color dark medium brown with posterior half of elytra blackish brown; tip of abdomen, antennae, palps, and legs light brown. Head and pronotum with denser, coarser punctation; elytral surface not rugulose with finer punctation notably coarser than punctation of head and pronotum. Eyes somewhat larger, 0.4 times as long as temples; longitudinal diameter comprising 6–7 ommatidia. Temples parallel, not widened posterior of eyes. Elytra slightly longer, sutural length 0.7 times as long as pronotal length, less narrowed across rounded humeri, and without clear depression in anterior half. Somewhat smaller; total body length 4.0 mm, forebody length 2.0 mm. Male unknown. Female: Gonocoxal plate slender, about 2.1 times as long as wide, with roundly subtriangularly extended basal margin without basal and subbasal ridge, subparallel, slightly concave lateral margins, and deeply, narrowly emarginate posterior margin (Fig. 257). Distribution: Frischianus curtipennis is native to the montane zone of Mt Kerinci, Indonesia’s highest mountain on Sumatra, where it is probably endemic due to its flightlessness. Etymology: The epithet curtipennis [adjective, Latin, composed of the adjective curtus (short) and the noun penna (wing)] refers to the reduced elytra and metathoracic wings of this new species. Remarks: The metathoracic wings were not examined to avoid damage of the single type specimen. They are expected to be reduced judging by the absence of the palisade fringe of abdominal tergite VII. Frischianus curtipennis is treated in the chapter of the F. laticollis lineage of the F. laticollis species group for purely practical reasons due to its similarity with F. subalpinus, to which it is compared. The long gonocoxal plate with a deep, narrow posterior emargination (Fig. 257) is more suggestive of the F. rufulus subgroup of the F. laticollis species group (cf. Figs 263–265). Frischianus curtipennis is not assigned to the F. laticollis lineage, but a species incertae sedis as long as male characters are unknown.
