Pycnoscelus undefined-F

Pycnoscelus sp. F Fig. 10 Material examined. China • 1 female; Yunnnan Prov., Mengla County, Menglun Town, Manbian Cun; 30 July 2009; Zong-Qing Wang leg. Measurements (mm). Body length: 17.4; pronotum length × width: 4.3 × 7.8; tegmen length: 2.5. Remarks. Pycnoscelus sp. F is currently represented by a single female specimen. This specimen is characterized by its strongly reduced tegmina (lobiform and lateral) and the complete absence of hind wings. Wing reduction is also observed in the females of P. micropterus Hanitsch, 1931, P. striatus (Kirby, 1903), P. femapterus Roth, 1998, and P. undulatus sp. nov. However, P. micropterus and P. striatus differ from Pycnoscelus sp. F by the tegmina reaching the abdominal terga, and the presence of hind wings. Furthermore, P. femapterus and P. undulatus sp. nov. can be distinguished from Pycnoscelus sp. F by the complete lack of both tegmina and wings. It is worth noting that no female specimens of P. puteus sp. nov. have been recorded, and both P. puteus sp. nov. and Pycnoscelus sp. F were collected from Menglun Town, Mengla County, Yunnan Province. It is plausible that Pycnoscelus sp. F represents the female form of P. puteus but it needs further study.
