Trialeurodes pseudoblongifoliae Dooley sp. nov.

Diagnosis. Puparium ( Figure 15 ): Habitus. Oval to elongate with pupal case length and width vary from 838-1116μm in length and 584-741μm in width; bright yellow with a dorsal a Y-shape pattern. Dense dorsal transparent wax secretions are present causing significant problems when removing the wax during the mounting process. Found solitary usually on the upper leaf surface near margin. Slide mounted specimen –Lateral margin crenulate with 10 irregular crenulations per 100μm. Dorsum. Longitudinal and transverse sutures terminate at the submarginal papillae. Dorsal disk with abdominal segments slightly differentiated only from the median to the subdorsum and less defined in the cephalothorax. A 6 segment more than twice the width of A 7 medially. Submedian abdominal depressions faint. Submargin with total number of 102-105 cone-shaped papillae ( Figure 15 ) in a continuous row, each being 19-26μm in length, oriented toward but not reaching the margin. A 1 through A 6 with poorly defined median abdominal tubercles subequal in size ranging from 24-39μm in diameter. Subdorsum with irregular row of tubercles of various sizes: on the cephalothorax consisting of one row and from A 1 to A 8 in two irregular rows. Vasiform orifice. Orifice is cordate in shape 166. 23μm in length and 150.5μm in width; operculum shieldlike covering almost the entire lingula exposing only the tip. Venter. Legs unarmed with microsetae but lacking spines. Antennae terminate at the T 1 pair of legs. Pores. Each marginal papilla with a central, basal disc pore, some with two; also present at base between submarginal papillae. Chaetotaxy. Submedian setal pair present are on the cephalon each 23-26μm in length ( Figure 15 ), A 1 setae each 17.7μm in length, A 8 setae 15-19μm in length, and caudal setae each 10-13.4μm in length.

Nevada distribution. Red Rock Canyon: Sandstone Quarry.
