Tetraleurodes quercophyllae Dooley sp. nov.

Diagnosis. Puparium ( Figure 11 ): Habitus. Oval sclerotized and black with pupal case length and width vary from 699-1222μm long and 574-963μm wide; wax forms a marginal ring; usually solitary on upper or lower part of leaf. Slide mounted specimen-Lateral margin. Ovoid length and width vary from 730-1270μm long and 560-960μm wide. Dentate, not differentiated at thoracic or caudal tracheal openings, with 6 to 8 teeth per 100μm; submarginal, pale glandular areas vary from thimble-shaped to distorted, not U or V-shaped ( Figure 11 ). Dorsum. Longitudinal suture terminates close to the margin. Transverse suture terminates on or before the subdorsal fold. Cuticle rugose from submargin to subdorsum being smooth in the median region. Eyespot absent. Submedian abdominal depressions well defined from A 1 to A 7. Median tubercles well defined from A 2 to A 7. Vasiform orifice. Orifice and operculum subcordate; operculum with dorsum rugose completely obscuring the lingula. Posterior notch absent on both the vasiform orifice and operculum. Pores. Tubercle-like small pores present in a single irregular row in the transverse band between the dorsal fold and microtuberculate band ( Figure 11 ) averaging from 60-80 pores combined for both sides. Each pore about 57μm in diameter. Numerous pores each associated with a porette present on dorsum on the subdorsum to the submedian areas: cephalic from 0-1 submedian and 0 to 2 subdorsum pores; T 2 with 0-2 submedial and 0 to 3 subdorsal pores; T 3 with 1-3 subdorsum pores only; A 1 pores absent or with 1 submedial or 1 subdorsal pore present; A 2 with 0-1 submedial pore present; A 3 with 0-1 submedial pores present; A 4 with 0-1 subdorsal and 1-2 submedial pores present; A 5 with 1-2 submedial and 0-2 subdorsal pores present; A 6 with 0-1 submedial and from 1-2 subdorsal pores present; A 6 with 0-1 submedial and 1-2 subdorsal pores present; A 7 from 0-1 submedial and 0-2 subdorsal pores present; and A 8 1-3 submedial present and no subdorsum pores. Chaetotaxy. Submarginal, thoracic and abdominal setae present; cephalic setae 15 m long, T 2 setae 10-30μm long; T 3 setae 15 to 25μm long; A 1 setae absent; and A 8 setae 5 to 16μm long. Submarginal setae at irregular pattern with 6-8 setae on transverse ridge between tubercle-like pores and microtuberculate band.

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