Panorpa deceptor Esben-Petersen, 1913
Diagnosis: This species has two distinct bands across the wings: an apical band broken by several small clear spots, and a pterostigmal band with posterior fork. Basal to these two bands is a basal band that is interrupted medially, with an elongated spot between basal and pterostigmal band. The meso- and metanota have a broad, pale, medial stripe. The male bears very short, narrow hypovalves that are only about half the length of the basistyles and medially divided almost to the base of the 9th sternite. The ventral parameres are unbranched and very long, extending almost to the end of the dististyles. Female genital plate elongate with elongate central stalk and posterior acute arms of plate.
Distribution – Geographical: This species was originally described (Esben-Petersen, 1913) from Taihorin ( = Talin = Dalin, Chiayi County), 7 November 1911, H. Sauter, 10♂♂, 19♀♀ (DEI); Taihorinsho ( = Talin), 7 September and 7 November, H. Sauter, 1♂, 6♀♀ (DEI); Kosempo (= Chiasien = Chaihsien = seems to be Ch"ia"hsien = Jiaxian, Kaohsiung County, 23.1151°N, 120.6381°E), 7 July 1911, H. Sauter, 1♂ (DEI); Sokutsu ( = Hsiaolin), May 1912, H. Sauter, 2♂♂, 1♀ (DEI); Anping, H. Sauter, 3♀♀ (DEI). In 1921 Esben-Petersen added further records: 1909, H. Sauter, 1♀ (RMNH); Taihorin, H. Sauter, 7♂♂, 7♀♀ (ZMHB); H. Sauter, 4♂♂, 4♀♀ (IRSNB). Issiki & Cheng (1947) record this species from Taihorin, May 1918, 1♀ (NTU). Additional records include: Taihorin, 7 September, 1♀ (USNM); Arisan (= Alishan), 2-23 October 1918, J. Sonan & M. Yoshino, 1? (USNM); Taipei County, Shihlin District, Yangmingshan National Park, 25°09’2-.62”N, 121°32’49.91”E, 1725 ft. [526 m], 18 November 1977, G. Hevel, 1? (USNM); same locality, except December 1965, E.M. Bravi, 1♀ (USNM).
Distribution – Temporal: Emergence dates are during May, July, September, October, November, and December. Records indicate that this is a species found both at high elevations and low elevations. I suspect that adults emerge late in the year at higher elevations and then at progressively lower elevations as the season gets cooler. The May record may indicate a second generation in the spring.
Ecology: The record from Alishan would indicate that this species can be found in cool, mixed forests. However, because it seems to be distributed widely over the island at quite different elevations, its habitat requirements may be less rigorous than with other species..
Biology: Nothing is known of immature stages or life cycle.
Notes: The heavily pigmented wings and very long male ventral parameres make this species unmistakeable. This species was probably named “deceptor” because of the superficial resemblance of the wings to those of Neopanorpa formosana.
