Panorpa pallidimaculata Issiki, 1929b
Diagnosis: This is one of the species with thin hypovalves and deep medial cleft between them. Hypovalves extend only about 2/3 length of basistyles. Ventral parameres with short basal spur, rather than elongate branch; valves extend to apex of basistyles, becoming broader at apex, with long apical setae. Medial cleft between dorsal valves with dark base.
Distribution – Geographical: Originally described from Mt. Tattaka ( = Sungkang), 7000 ft. [2133 m], 20 July 1925, S. Issiki, 1♂ (depository ?); and east side of Mt. Guntaisan, 7000 ft. [2133 m], 11 July 1925, S. Issiki, 3♂♂ (depository ?).
Distribution – Temporal: Adults have only been collected in mid – July.
Ecology: The type localities appear to be high, cool, moist, montane forests.
Biology: Nothing is known of immature stages or life cycle.
Notes: Females of this species are still unknown. At this time ♀♀ cannot be identified without association with males. The feature that distinguishes this species is the basal spur of the ventral parameres of ♂♂.
The name “pallidimaculata” probably refers to the faint markings on the otherwise colorless wings.
