Aleuroparadoxus arctostaphyli Russell 1947

Diagnosis. Puparium ( Figure 4 ): Habitus. Light dark brown to black in color; elliptical to subcircular in shape; with waxy glassy rods extending from submarginal and dorsal papillae. Slide mounted specimen – Lateral margin. Thoracic tracheal pore area indicated by 2-4 wide marginal teeth and submarginal ridges; abdominal tracheal pore area less distinct. Dorsum. Submarginal papillae 32-56μm (usually 40-50 m) long and 16-18μm wide, not contiguous, the majority separated from each other by a distance of about 1/5 the width of a papilla apart. Tracheal folds present terminating at the dentate margin; submarginal row of noncontiguous flat elongate papillae present with 2 to 3 pairs of cephalic subdorsal modified papillae and 0 to one central subdorsal pair on prothorax; each papillae ranged from 20 to 64μm. Four pairs of scattered reniform papillae present on the cephalon. Vasiform orifice. Rather broad posteriorly, 68-88μm long and 60-80μm wide. Operculum 64-80μm long and 56-72μm wide. Venter. Antennae terminate at the T 1 position, abruptly tapered, short finger-like at apex. Each anterior leg with 1-3 poorly to well developed, blunt spines present along the anterior margin of the coxa just mesad of the rugose band; middle and posterior legs each with a seta apparently about 20μm long located in the rugose band. Pores. Thoracic tracheal pore absent. Chaetotaxy. Each cephalic, A 1 and A 8 abdominal setae range from 24 to 32μm long; caudal setae from 10 to 30μm; ventral abdominal setae from 35 to 40μm long.

Nevada distribution. Red Rock Canyon NCA: Sandstone Quarry.

Nevada hosts. Rhamnaceae : Ceanothus sp.

Nevada materials studied (2 puparia). Collected at Red Rock Canyon NCA: Sandstone Quarry on 12- ix-2003 deposited in the USNM collection.

Comments. This is a new state record for Nevada and the only species of this genus known to occur in Nevada. It is also a new host for this species collected on Ceanothus sp.
