Abstract
Neopanorpa van der Weele, 1909 is the second largest genus in Panorpidae, and over 170 Oriental species have been reported hitherto. In this paper, we describe two new species: Neopanorpa luojishana sp. nov. and Neopanorpa xingmini sp. nov. from Southwest China. We also report the first discovery of the male of Neopanorpa ocellaris (Navás, 1908) from Guangxi and Guizhou, China, a species recorded from Sikkim previously. Neopanorpa brevivalvae Chou & Wang, 1988 is synonymized with Neopanorpa lungtaushana Cheng, 1957. In addition, Neopanorpa furcula nom. nov. is proposed for Neopanorpa furcata Zhou, 2005, a junior homonym preoccupied by Neopanorpa furcata (Hardwicke, 1825). The biogeographical implications of some Neopanorpa species are discussed in brief.
Highlights
Panorpidae Latreille, 1805 are the largest extant mecopteran family with over 490 species distributed in the Holarctic and Oriental Regions (Penny & Byers 1979; Bicha 2018; Wang & Hua 2019)
The new species can be recognized by the following features: 1) vertex yellowish brown with a broad black stripe enclosing ocellar triangle and extending to occiput (Fig. 2C); 2) wings nearly lacking markings except distinctly reduced apical and pterostigmal bands (Figs 1, 2A–B); in males, 3) notal
European Journal of Taxonomy 543: 1–17 (2019) organ well-developed, slender stick-like and extending slightly beyond posterior border of T5 (Figs 1, 2A, D); 4) three postnotal organs on T4‒T6, respectively (Fig. 2D); 5) genital bulb distinctly elongated, over two times as long as wide (Fig. 2E–F); 6) gonostylus bearing a tuft of long stout setae on middle of ventral surface (Fig. 2F–G); and in females, 7) medigynium with long axis nearly two-thirds of total length, and greatly divergent apodemes (Fig. 2L)
Summary
Panorpidae Latreille, 1805 are the largest extant mecopteran family with over 490 species distributed in the Holarctic and Oriental Regions (Penny & Byers 1979; Bicha 2018; Wang & Hua 2019). Neopanorpa and Leptopanorpa resemble each other by their slender rostrum, relatively narrow wing base in both sexes, and a greatly developed notal organ in the males. These two genera can be differetiated from all the other genera in Panorpidae by the vein 1A ending proximal to the origination of Rs, and a single crossvein between 1A and 2A in the forewings (Issiki 1933; Cheng 1957a; Wang & Hua 2019). The sister-group relationship between a subset of Neopanorpa and Leptopanorpa was proposed by Willmann (1989) based on morphological comparisons, and corroborated by recent morphological (Ma et al 2012) and molecular phylogenetic analyses (Miao et al 2019). These results indicate that Neopanorpa is a paraphyletic group, forming a monophyletic clade together with Leptopanorpa, more detailed research into Neopanorpa is urgently needed (Miao et al 2019)
