Panorpa horiensis Issiki, 1929a
Diagnosis: This is the only species of panorpid in Taiwan with a horn on the 6th abdominal tergite of males. The vertex is orange, and meso- and metanota are completely black. In the male genital bulb, the ventral parameres are short, blade-like, apically tapered with setae along the mesal surface. The aedeagus has a pair of flat, apically rounded dorsal lobes.
Distribution – Geographical: This species was originally described from Hori (Polisha)(= Puli, Puli Township, Nantou County , 23.9935°N, 120.9646°E), 10 May 1913, M. Maki, 3♂♂, 3♀♀ (depository ?); and Musha (= Musya = Mushi = Wushe, Ren-ai Township, Nantou County, 24.02655°N, 121.11753°E), 18 May 1919, J. Sonan, 1♂ (depository ?)(Issiki, 1929a). Yie (1951) recorded this species from Sankakuhō ( = Meifeng), 2300 m, May. Additional records are: Higasinōkō (= Tungnunkao = East Nenggao, 24.0226°N, 121.3055°E), 3 June 1943, S. Issiki, 1♂ (USNM); Hsinchu County, Shei-pa National Park, Wu-Lu East trail, 24°30.095’N, 121°07.439’E, 2043 m, 30 April 2010, A. & N. Penny, Tsou Mei-Hua, and Chi-Feng Lee, 1♂ (CAS).
Distribution – Temporal: Records indicate a late April to early June emergence.
Ecology: This species is found in forested areas at relatively high altitudes.
Biology: Nothing is known of immature stages or life cycle.
Notes: Issiki (1927) had originally indicated that the series of specimens collected at Polisha in 1913 was Panorpa concolor E.-P. Issiki & Cheng (1947) indicate that a ♀ allotype, collected by “M. Marki”[sic] was deposited in NTU.
