Aleuropleurocelus nevadensis Dooley sp. nov.

Diagnosis. Puparium ( Figure 7 ): Habitus. Black in color; oval to rotund with pupal case length and width vary from 554-704μm long and 409-602μm wide; usually solitary on upper or lower surface of the leaf without noticeable wax formation. Slide mounted-Lateral margin. Deflexed margin ( Figure 7 ) oriented towards median appearing as two separate dentate margins that are separated by a 28-37μm distance. The physical margin is tuberculate with irregularly-shaped structures. True lateral margin is dentate forming a fold-like inner concentric ring with the teeth pointing toward the margin and with a basal row of rectangular-elongated, divided submarginal gland at the base of the teeth ( Figure 7 ). Dorsum. Entire dorsum is patterned with multiple rows and clusters of various sized granules from the cephalon to the caudal areas and from the subdorsum (deflexed inner margin) to the submedian area. Median area weakly sculptured. Longitudinal molting suture terminates at margin and is 298μm long. The suture has a single row of granules on each side ( Figure 7 ) extending from the transverse suture to 2/3 the distance toward the anterior margin giving a zippered appearance. The transverse suture extends out close to the inner margin and curves upwards terminating at the true inner margin at the level of the T 2 suture. A pair of narrowly transverse eyespots each with a thickened lower margin ( Figure 7 ). Venter. Antennae extending posteriorly to the T 1 pair of legs. Thoracic cuticle with a moderate spinulose band present transversing the basal areas of the legs while a broad spinulose area occurs lateral to the mouth parts ( Figure 7 ); abdominal cuticle weakly granulated from the margin to the submargin and smoother toward the median. Vasiform orifice. Widely cordate, 55.6μm long and 68.4μm wide, with a moderate to broad lateral and posterior margin; anterior margin not defined. Operculum 26.3μm long and 35.5μm wide; completely covers the lingula and most of the vasiform orifice. Caudal protuberance absent or greatly reduced. Caudal setae widely separated ( Figure 7 ). Pores. Scarce, on cephalon, thorax and abdomen (submedian to subdorsum). Chaetotaxy. Thoracic and A 1 setae absent; A 8 pair of setae present (38.5- 48.6μm long), each arising from a tubercle base on the anterior-lateral margin of the vasiform orifice. Caudal setae pair is broken off or missing.

Nevada distribution. Red Rock Canyon NCA: Pine Creek Canyon; Sandstone Quarry.

Nevada hosts. Ericaceae : Arctostaphylos sp. ; Fagaceae : Quercus sp. and Q. turbinella ; Hydrophyllaceae : Eriodictyon sp.

Etymology: The name is the Latin adjective describing Nevada as the origin of the species collected.

Comments. The broadly oval-shaped puparium with a greatly reduced or lacking a caudal protuberance ( Figure 7 ) and widely-separated caudal setae differentiates this species from A. ceanothi and A. nigrans which have a boat-shaped puparium with a pronounced caudal protuberance and the caudal setae set close together. It is most similar in shape to Aleuropleurocelus abnormis Quaintance not known to occur in Nevada but differs from the latter by lacking a wide, curving sclerotized area along the anterior margin. The puparium length and width ranges were taken from 30 puparia measured. The measurements for the individual structures were taken from the Holotype.
