Platyceroides (Platyceroides) potax Paulsen

Platyceroides potax Paulsen, 2014: 1 , original combination.

Type series. Holotype male ( CDFA) labeled: a) “ USA: CA: Butte Co. / Coutolene [sic] Park ; Paradise / 1-JUN- 2006 ; R. Penrose / Ex: EtOH trap in forested area”; b) on red paper, “ Platyceroides / potax Paulsen / HOLOTYPE ”. See Paulsen (2014) for details on the rest of the type series.

Remarks. This species was described recently (see Paulsen 2014, 2015). The flagellum of the male genitalia ( Fig. 12 E) is provided for comparison with P. barrae . Since its description, additional locality records have been added ( Fig. 28 ). The first females of P. potax have been examined from Pulga, Butte County, and Challenge, Yuba County, California. They have shagreened pronota, unlike the nearby P. barrae , and lack the thickened clypeus of female P. latus . Also, numerous males have subsequently been collected at traps containing 70% ethanol in Magalia, Butte County (Brady Richards, personal communication).
