Cerapanorpa Gao, Ma & Hua, 2016, an endemic genus of Panorpidae in central China’s mountain regions, currently comprises 21 described species. Recently, the short-horned scorpionfly C. brevicornis (Hua & Li, 2007) was confirmed to contain two valid species by phylogeographic and morphological data. Individuals from the highlands of the eastern Bashan Mountains were suggested as a good species, separated from the original short-horned C. brevicornis.
Cerapanorpa alpina sp. nov. was described from the alpine zone of the eastern Bashan Mountains in central China. The new species differs from its congeners by the following combination of characters: male bearing an extra-short anal horn on posterior margin of tergum VI; paramere elongate, extending beyond the median tooth of gonostylus and curved laterally at basal half; female medigynium slightly constricted medially without dorsal basal plate. The species number of Cerapanorpa is raised to 22.

The single-horned scorpionfly genus Cerapanorpa Gao, Ma & Hua, 2016 was erected with Panorpa obtusa Cheng, 1949 as the type species (
The genus Cerapanorpa currently consists of 21 described species, which are endemic to the montane archipelagos of central China’s mountains (
Adult scorpionflies were caught with collecting nets from the eastern Bashan Mountains in central China (Fig.
Male: Frons, vertex, occiput and postgena brownish-black (Fig.
Adults of Cerapanorpa alpina sp. nov. A, B. Male and female habitus in dorsal views; C, D. male head in frontal and posterior views; E. male dorsum of head and thorax; F. male abdomen in lateral view. Abbreviations: ah, anal horn; ms, mesonotum; mt, metanotum; no, notal organ; pr, pronotum. Abdominal segments are indicated by Roman numerals. Scale bars: A, B = 5 mm; C, D = 0.5 mm; E, F = 1 mm.
Male genitalia: Genital bulb elliptical, yellowish-brown (Fig.
Genitalia of Cerapanorpa alpina sp. nov. A, B. Male genital bulb in ventral and dorsal views; C, E. aedeagus in ventral and lateral views; D. female terminalia in ventral view; F, G. medigynium in ventral and dorsal views. Abbreviations: ax, axis; ce, cercus; dp, dorsal process; dv, dorsal valve; ep, epandrium; gcx, gonocoxite; gs, gonostylus; hv, hypovalve; lp, lateral process; mp, main plate; pa, posterior arm; pm, paramere; sgp, subgenital plate; vbp, ventral basal plate; vv, ventral valve. Scale bars: A, B, D = 0.5 mm; C, E–G = 0.2 mm.
Female: Head, thorax and abdomen similar to those of males in colouration and pattern (Figs. 2B and 4B). Head length 3.85–4.26 mm. Forewing length 14.59–16.22 mm, width 3.54–3.96 mm. Hindwing length 13.28–14.85 mm, width 3.10–3.45 mm.
Female genitalia: Subgenital plate nearly trapezoidal, shallowly emarginate terminally, with long bristles on lateral distal part (Fig.
The new species can be distinguished from its congeners by the following combination of characters: postgena brownish-black; male tergum VI with an extra-short anal horn on posterior margin; paramere exceeding beyond the median tooth of gonostylus and curved laterally in basal half; female subgenital plate nearly trapezoidal; medigynium lacking dorsal basal plate.
The specific epithet ‘alpina’ is derived from the Latin adjective ‘alpinus’, referring to the high elevation habitats in the eastern Bashan Mountains.
China (Chongqing, Shaanxi and Hubei provinces).
The new species was found exclusively in the eastern Bashan Mountains with an altitude of above 1800 m and was especially rich on the alpine shrub meadows of mountaintops (Fig.
The new species is closely allied to C. brevicornis (Hua & Li, 2007), but differs from the latter by the following characters: postgena brownish-black (cf. yellowish-brown); male paramere elongate, exceeding beyond the median tooth of gonostylus and curved laterally in basal half (cf. shorter and not curved in basal half); female subgenital plate nearly trapezoidal (cf. elliptical); main plate of female medigynium slightly constricted medially (cf. narrower at base and gradually broadened towards the apex).
Cerapanorpa alpina sp. nov. and C. brevicornis (Hua & Li, 2007) share a most recent common ancestor (
Cerapanorpa alpina sp. nov. is endemic to the alpine zone of the EBMs, an important climate refugium and a centre of endemism for montane species (
