Panorpa taiheisanensis Issiki, 1929a
Diagnosis: This is one of the species in which males have narrow hypovalves with deep medial cleft. It differs from others in two respects: the thorax has a pale mid-dorsal stripe; and the male ventral parameres are long, unbranched, and do not bear long setae. These ventral parameres extend to the basal lobe of the dististyles. Female subgenital plate without apical notch; genital plate with narrow axial rod and flat plate without lateral arms.
Distribution – Geographical: Mt. Taiheisan ( = Taipingshan, Datong Township, Yilan County), 24°32’36.29”N, 121°30’40.88”E, 25 August 1923, T. Shiraki, 1♂, 1♀ (depository ?).
Distribution – Temporal: Known only from the type series collected on 25 August.
Ecology: This is an area of high, cool, moist, montane forests.
Biology: Nothing is known of immature stages or life cycle.
Notes: The name of this species is derived from the name “Taiheisan,” which is a mountain range now included in Taipingshan National Forest Recreation Area (http://www1.forest.gov.tw/RA_En_JP/0100001/RA_EN-01.htm).
Issiki and Cheng (1947) designated the ♀ as allotype, and the ♂ thus becomes, by default, the lectotype.
