Abstract
Panorpa Linnaeus, 1758 is the largest genus in the scorpionfly family Panorpidae. In this paper, a taxonomic review of the Panorpa wormaldi group is provided, with two new species described from China: Panorpa fengyanga Wang & Suzuki, sp. nov. from Zhejiang, and Panorpa zhuohengi Wang & Suzuki, sp. nov. from Guangdong. The male of Panorpa implicata Cheng, 1957 is discovered and described for the first time. A distributional map and keys to species are also provided for this group. Species number in this group is updated from 17 to 19. In addition, their biogeographical and evolutionary implications are briefly discussed.
Highlights
Members of the family Panorpidae Latreille, 1802 are commonly calledscorpionfliesdue to their males’ enlarged and recurved genitalia, which give a resemblance to the scorpion’s stinger
We present a taxonomical revision of the P. wormaldi group, with two new species described from Guangdong and Zhejiang, China
The Panorpa wormaldi group sensu Issiki, 1933 Figs 1–6. Diagnosis This group of species was originally recognized by the following characters: 1) rostrum relatively short and stout; 2) wings held roof-like over abdomen at repose; in males, 3) gonostyli (= dististyli) very short, approximately half as long as gonocoxites; 4) parameres often furcated and bearing long stout spines; 5) aedeagus with lateral processes greatly elongated; and in females, 6) medigynium with a greatly sclerotized dorsal plate, greatly elongated posterior arms and axis, and poorly developed main plate
Summary
Members of the family Panorpidae Latreille, 1802 are commonly calledscorpionfliesdue to their males’ enlarged and recurved genitalia, which give a resemblance to the scorpion’s stinger. Panorpa Linnaeus, 1758 is the largest genus in this family, with approximately 260 species distributed among Europe, Asia and North America This genus is considered a paraphyletic group and probably deserves further split (Wang & Hua 2021). The Panorpa wormaldi group was firstly introduced by Issiki (1933) for six species from Japan (Honshu and Kyushu) and China (Taiwan). Members of this group are mainly characterized by: wings held rooflike over abdomen at repose, male gonostyli (= dististylus) very short, approximately half as long as gonocoxites, and female medigynium with a greatly sclerotized dorsal plate, greatly elongated posterior arms and axis, and poorly developed main plate. Twelve similar species were described from China
