FIGURE 1. Fistulatus quadrispinosus sp. nov. A, Male, dorsal view; B, head, dorso-anterior view; C, face; D, male, lateral view; E–F, male pygofer, lateral and caudal view; G, valve, subgenital plates and style, ventral view; H–J, aedeagus, ventral, lateral and dorsal view (apex amplification); K, 2nd abdominal tergite, dorsal view; L–M, male 1st sternal apodeme, dorso-anterior and anterior view; N, male 2nd sternal apodemes, dorsal view; O, fore femur, anterior view.

Male genitalia. Pygofer lobe with dorsal and ventral margins extended into spinelike processes caudally, directed medially. Valve nearly pentagonal. Subgenital plate without macrosetae, distally prolonged and narrowed. Style apical process rostriform. Connective Y-shaped with stem very short, branches converging apically.

Aedeagus with dorsal apodeme well developed; shaft long and tubular, strongly curved dorsad with dorsal margin sinuate in lateral view, dorsal surface with medial subapical flange and pair of short slender processes slightly distad of midlength curved laterally and tapered to apex and shorter pair of acute processes at apex; gonopore large, apical on posterior surface.

Material examined. Holotype: male, China, Zhejiang Province, Qingliangfeng Mountains, Longtangshan Country, 5.viii.2011, Coll. Lu Lin ( NWAFU).

Etymology. The specific epithet “ quadrispinosus ” is derived from this species having four aedeagal processes.

Remarks. This species resembles F. luteolus based on the characters of the pygofer, but can be differentiated from the latter by the aedeagus having a pair of narrow processe in the middle. Also the species is similar to F. bidentatus , but the latter lacks ventral processes of the pygofer and the shape of the aedeagal processes is also different.
