Polycomus He & Ma, 2022

He, Zhi-Xin, Wu, Qian & Ma, Li-Bin, 2022, A new genus and two new species of Swordtail Crickets (Orthoptera: Trigonidiidae; Trigonidiinae) from China, Zootaxa 5124 (5), pp. 585-593 : 589

Genus Polycomus He & Ma , gen. nov.

Chinese name: 毛ṅDza

Type species: Polycomus exspiravit sp. nov., here designated.

Etymology. The 'polycomus' refers to the strongly pubescent body of the new.

Diagnosis. This genus has a distinct epiphallus ( Fig. 4D–F ). Epiphallic median lobe scimitar-like, and the apex curved outward. Epiphallic lateral lobe nearly shaped as a rectangular. The sclerotized portion of ectoparamere sickle-like, tapering and apically obtuse.

Remarks. The new genus is similar in appearance to Amusurgus Brunner von Wattenwyl, 1893 , but varies in male genitalia traits. The epiphallic lateral lobe of this new genus is slightly rectangular in shape and armed with a truncated tip, and the ectoparamere is sickle-shaped. Amusurgus , on the other hand, has a rod-like epiphallic lateral lobe and a truncated ectoparamere apex (Asian species, e.g., Amusurgus bispinosus He et al. 2010 , Amusurgus fulvus Brunner von Wattenwyl, 1893 , and Amusurgus caerulus Tan, 2022 ) or a finger-like epiphallic lateral lobe and median lobe (Australian species, e.g., Amusurgus kanyakis Otte & Alexander, 1983 , Amusurgus minmirri Otte & Alexander, 1983 , and Amusurgus nilarius Otte & Alexander, 1983 ).
