Specimen examined. Taiwan. Nantou County: Kao-Leng Dyi, 18 km W of Wushe, 24°4.605'N 101°7.583'E, 2074 m, from tree trunks at night, 18–19.iv.2002, leg. D.A. Anstine, Gy. Fábián & O. Merkl (1 3, HNHM).

Diagnosis. Recognized within Haematoloecha by the combination of the following characters: head black, anterior lobe of pronotum black, posterior lobe bright red; anterior lobe of pronotum much shorter than posterior lobe (about 1: 1.4); paramere apically pointed, with a broad triangular dorsal lobe. The species can readily be identified by its original description and illustrations ( Tachikawa 1968).

Distribution. Japan. Honshū; Shikoku; Oki Islands: Dōgo Is.; Izu-Shōtō Islands: Kōzu Is., Mikura Is. ( Hayashi 2002; Shimada & Ishikawa 2004; Hayashi et al. 2006). Taiwan! (see above). — New record for Taiwan.

Biology. The species seems to be rare, capture of only a few specimens have been reported so far. A female was collected from the inside of a fallen log infected by white-rot fungus on Dōgo Island in January 2004; the specimen was probably overwintering ( Shimada & Ishikawa 2004). The specimen examined by us was collected from tree trunks at night.

Taxonomy. This species is highly similar to H. fokiensis Distant, 1903 , described from Fujian Province of China, subsequently reported from several places in southern and southeastern China. They differs mainly in the following characters (character states of H. fokiensis in brackets): anterior lobe of pronotum black (red); anterior lobe of pronotum about 0.7 times as long as posterior lobe (0.85–0.9 times as long). The paramere is basically of the same structure, both sharing the broad dorsal lobe around its middle; the figures provided by Tachikawa (1968: 42, fig. 3) and Hsiao and Ren (1981: 433, fig. 1298) are correct but they show the respective parameres in a slightly different aspect.
