Panorpa concolor Esben-Petersen, 1915
Diagnosis: This species is still only known from the type series of ♀♀. Consequently, it is somewhat difficult to define this species. The wings have no dark markings, except a faint darkening of the pterostigma.
Distribution – Geographical: Tainan County, Anping, 22°59’31.92”, 120°09’55.52”E, 1907, Wileman, 2♀♀ (BMNH).
Distribution – Temporal: None available.
Ecology: Unknown.
Biology: Unknown.
Notes: This is a puzzling species. First, the type series apparently was collected at sea level, but in Taiwan the species of Panorpa with almost no wing markings are found at high elevations. Issiki (1927) described a series of 3♂♂, 3♀♀ of this species from Hori (= Puli), which he later (Issiki, 1929b) used for the original description of Panorpa horiensis. There have been no further records for this species in the literature. The most distinctive feature of Panorpa horiensis is the anal horn of the male, but without a male of Panorpa concolor, it is impossible to make comparisons.
The name refers to the lack of dark markings in the wings.
