Panorpa longiramina  Issiki & Cheng, 1947


Diagnosis: 
Males of this species have a genital bulb with very short, thick hypovalves that reach only 2/3 the length of the dististyles with a short medial cleft, leaving a long, broad 9th sternite.  The ventral parameres are divided into three setose branches: one angled medially from the base; one short medial branch with long apical setae; and a long, lateral branch that extends beyond the basal lobe of the dististyles.


Distribution – Geographical: 
Originally described from Taiheisan (= Ta-shu-lin, Takao Hsien = Dahan Mountain, Chunrih, Pingtung County, 22.4021°N, 120.7023°E), 9 May 1942, S. Issiki, 1♂, 1♀ (holotype, allotype – NTU); Musha (= Wushe, Ren-ai, Nantou County, 24.02655°N, 121.11753°E), 18 May – 15 June 1919, T. Okuni, J. Sonan, K. Miy., and M. Yosh., 1♂ (paratype – NTU); Arisan ( = Alishan, Alishan Township, Chiayi County, 23°26’09.72”N, 120°46’46.98”E), June 1914, M. Maki, 2♂♂ (paratypes – NTU); 29 April 1917, J. Sonan, 1♂ (paratype – NTU); 26 April 1931, T. Shiraki, 1♂ (paratype – NTU); Horishia ( = Puli, Puli Township, Nantou County, 23°59’56.52”N, 120°59’48.09”E), 10 May 1913, M. Maki, 5♂♂ (paratypes – NTU).  Yie (1951) recorded this species from Yü-shih (Miharashi)[perhaps Nantou County, Ren-ai Township, 24°02’52”N, 121°09’22”E), 1700 m; May and June.  Additional records include:  Taiheisan, (= Ta-shu-lin, Takao Hsien = Dahan Mountain, Chunrih, Pingtung County)(22.4021°N, 120.7023°E), 1900 m, 9 May 1942, S. Issiki, 2♂♂, 1♀ (USNM); Highway 31, km 36, Nantou County, 23°31.905’N, 120°53.802’E, 2140 m, A. & N. Penny, C.-F. Lee, and Ta-Hsiang Lee, 2♂♂ (CAS).

 

Distribution – Temporal:  Records exist for late April until June.


Ecology: 
This species appears to inhabit cool, moist, montane forests at rather high elevations.


Biology: 
The morphology and development of the immature stages is discussed by Yie (1951).


Notes: 
This species was named “longiramina” for the distinctive long branches of the male ventral parameres.
