Caseya dorada ( Chamberlin 1941)

Placerna dorada Chamberlin 1941:10 .

Caseya dorada, Gardner & Shelley, 1989:234 .

The type locality for this species is 9 miles north of Placerville, El Dorado Co., California; Gardner and Shelley (1989) presented numerous records from Nevada, Sacremento, El Dorado, Placer, Amador and Calaveras Cos. Gardner and Shelley (1989) stated that C. dorada was both common and abundant throughout its range; dense populations were found near El Dorado living in loose shale covered with deciduous leaf litter. The species may occur syntopically with C. heteropa montana Gardner and Shelley 1989 , but is considerably smaller, 10–11 mm long, while heteropa montana is about 20 mm long. The overlap in the distribution of the two as shown by Gardner & Shelley occurs only in the far southwestern corner of El Dorado Co. The May record from Riverton given below is the latest in the year that this species has been collected. The records given by Gardner and Shelley (1989) are all from the period November to March, except for a single April collection.
