Panorpa nokoensis  Issiki, 1929b


Diagnosis: 
Vertex of head and nota of thorax uniformly dark brown to black.  Male hpovalves narrow, with medial cleft reaching almost to base of 9th sternite; hypovalves do not reach apex of basistyles.  Ventral parameres branched at base, with medial branches obliquely angled to almost touch medially; lateral branches straight, extending beyond basal tooth of dististyles, with apical cluster of long setae.  Dorsal valves widely separated, evenly tapered to points, with dark mass at base of medial cleft between dorsal valves.  Basal lobe of dististyle without prominent teeth..


Distribution – Geographical: 
Nōkō ( = Nengkao, = Nenggao) (west side of Mt. Kiraishusan), 9000 ft. [2,743 m], 26 June 1927, S. Issiki, 3♂♂, 4♀♀ (depository ?).  Yie (1951) records this species from Miharashi ( = Yü-shih) [perhaps Nantou County, Ren-ai Township, 24°02’52”N, 121°09’22”E], 1700 m, June; and Ononu, June.


Distribution – Temporal: 
Known only from the type series collected in late June.


Ecology: 
This species inhabits quite high, moist, cool, montane forest.


Biology: 
Nothing is known of immature stages or life history.


Notes: 
This species is very similar to Panorpa longititilana.  However, Issiki (1929b) pointed out five differences between the two species: Panorpa longititilana has 1) a row of very fine hairs along the inner margin of the branches of the hypandrium [ = hypovalves], 2) apical branches of epiandrium [9th tergite] a little longer and narrower, 3) basal teeth along the inner edge of the dististyles more pronounced, 4) ventral valves longer, more curved; medial branch somewhat shorter, 5) the membranous portion of dorsal valves more prominent,  That being said, Issiki (1929b) suggested that these differences may only be subspecific variations.


A ♀ from the type series was designated allotype by Issiki & Cheng (1947), but no lectotype has ever been assigned.


The name “nokoensis” comes from the name “noko” the type locality.  This locality is part of a national trail system from the high central mountains near Puli to the east coast at Hualien (Kelly & Brown, 2007).
