Panorpa pectinata Issiki, 1929b
Diagnosis: This is one of the species with narrow hypovalves with deep medial cleft. The ventral parameres have a basal spur similar to Panorpa pallidimaculata, but with setae all along the medial margin of the main valve and a small apical bifurcation.
Distribution – Geographical: Mt. Arisan ( = Chiayi County, Alishan Township, Mt. Alishan), 2200 m, 30 August 1927, J. Sonan and K. Shibata, 2♂♂, 3♀♀ (depository ?); Mt. Guntaisan, 6500 ft. [1981 m], 11 July 1925, S. Issiki, 1♂ (depository ?).
Distribution – Temporal: July and August.
Ecology: This species is found in high, cool, moist, montane forests.
Biology: The morphology and development of the immature stages is discussed by Yie (1951).
Notes: The combination of basal spur and apically bifurcate vental paramere will separate this species from Panorpa pallidimaculata and all other species. The name “pectinata” probably refers to the comb-like appearance of setae along the mesal length of the ventral parameres.
