diagnosis
Diagnosis. This genus has a distinct epiphallus (Fig. 4 D – 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.
discussion
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).
