Platyceroides (Platyceroides) marshalli Paulsen

Platyceroides marshalli Paulsen, 2015: 1 , original combination.

Type series. Holotype male ( OSAC) labeled: a) “ USA: OR: Jackson Co. / 7 km S of Gold Hill, Galls Creek / Rd; 42.367, -123.057; 566m / soil/litter under madrone branch / (~ 10 cm diam.); 3.VI.2015 / MJ Paulsen, C Marshall”; b) on red paper, “ Platyceroides / marshalli Paulsen / HOLOTYPE ”. See Paulsen (2015) for details on the rest of the type series.

Remarks. This species was described recently (see Paulsen 2015). The male genitalia of this species ( Fig. 12 F) bears some resemblance to that of P. agassii , which may indicate a relationship between the two species. Since publication, additional locality records have been added ( Fig. 28 ). Specimens have been collected in southern Jackson County, Oregon, along Interstate 5 not far from the California border (Michael Kippenhan, personal communication). It is likely that this species will also be found in Siskiyou County , California .
