Neopanorpa sauteri (Esben-Petersen, 1912)
Diagnosis: Vertex dark medially and orange laterally near compound eyes. Meso- and metanota with broad pale areas laterally and narrow dark brown line medially. Forewing with apical band, usually with tapered basal spur; pterostigmal band caudally branched with thin diagonal line to anterior margin from basal branch; basal band interrupted in middle and posterior spot often connected to base of diagonal line at anterior margin between the two bands. Usually two spots basal of basal band: one in middle of wing and one at apex of 1A along wing margin. Male with extremely long nodal organ from 3rd to almost touch tip of recurved genital bulb.
Distribution – Geographical: This species was originally described from Koshun, August 1909, H. Sauter, 1♂ (DEI). Other records (from Esben-Petersen, 1921) include: Chip-Chip, 1909, H. Sauter, 5♂♂, 5♀♀ (Leiden) and Kankau, 1909, H. Sauter, 1♂ (Berlin). Issiki and Cheng (1947) and Yie (1951) record this species from Raisha, 900 m, May and November. Additional records are from: Pingtung County, Manzhou Township, Lide, 27 Feb. – 13 March 2010, M.L. Jeng, 1♂, flight intercept trap (CAS); Nanrenshan, 22°05’08”N, 120°51’21”E, <500 m, 27 Feb. – 14 March 2010, M.L. Jeng, 1♀, flight intercept trap (CAS); Nanrenshan, 22°05’08”N, 120°51’21”E, <500 m, 27 March – 5 April 2010, 1♀, flight incept trap (CAS). Additional specimens are: Syussuiha, 26 March 1944, S. Issiki, 2♂♂ (USNM); Taito-Syussuiha, 26 March 1944, S. Issiki, 1♀ (USNM).
Distribution – Temporal: The ♂ type from Koshun was collected in August, 1909. The ♀ specimen indicated in Issiki & Cheng (1947) was collected on 18 May 1947. The records from Pingtung County indicate an early season emergence at relatively low elevation at the extreme southern end of Taiwan, but may emerge later in other parts of the island.
Ecology: The collector of the recent specimens, M.L. Jeng, indicates that “The final section of the trail where the scorpionflies were collected is under a primary forest, shady and moist.”
Biology: Yie (1951) indicates that there are 18.0 eggs per egg cluster. The morphology and development of the immature stages is discussed.
Notes: This is one of a group of four related species of Neopanorpa from Taiwan with pale areas at the base of the wings and males having hypovalves with a circular opening at the medial base of elongate, triangular hypovalves .
This is also one of four known species of Neopanorpa in which the male has an extremely long notal organ. The others are: N. tibetensis Hua & Chou, 1999, (from Xizang, China); N. choui Cheng, 1949 (from Sichuan, China), and an undescribed species from southern Thailand. In an interesting example of parallel evolution, there are also two species of Panorpa from Japan that have an extremely long notal organ in males: P. leucoptera Uhler, 1858 and P. takenouchii Miyake, 1908.
