Diagnosis. Puparium ( Figure 13 View Figure 13 ): Habitus. Puparium minute, bright yellow from ovoid to elongate posteriorly; from 770-750μm in length and 500-550μm in width. Slide mounted specimen – Lateral margin. With narrow crenulations, 20 or more per 100μm. Dorsum. Transverse molting suture extends to the margin and slightly anterior to the position of its midpoint with the longitudinal suture. Submarginal papillae numbering 64-74 and arranged in an irregular single line; papillae apically pointed and oriented towards the margin; papillae separated normally by a distance apart the width of a papillae. Venter. Legs unarmed (lacking spine). Vasiform orifice. Elongate cordate with a slight inverted tooth at posterior end; operculum covering all but the lateral lobes of the lingula. Pores. Marginal discoidal pore associated with each papilla for the most part. Submedian disc pores usually with 1 pair per segment except for A 2 and A 8 segments each having from 2 to 6 pores. Chaetotaxy. Cephalic, A 1 and A 8 setal pairs present; C 1 and A 1 setal pairs unusually large in one specimen and short in second specimen. See Russell (1948: 76-77) for complete description.

Nevada distribution. Red Rock Canyon NCA: Along scenic route roadside between Calico Hills Trailhead and Sandstone Quarry; Willow Springs.

Nevada hosts. Hydrophyllaceae : Eriodictyon crassifolium ; Solanaceae : Datura sp. (in Clark County, Nevada 2009).

Nevada materials studied (2 of 3 puparia deposited in the USNM at Beltsville, MD): Red Rock Canyon NCA, Nevada along scenic route roadside between Calico Hills Trailhead and Sandstone Quarry: 36 o 08.763N and 115 o 25.844W GoogleMaps ; and at Willow Springs : 36 o 07.735N and 115 o 28.413W GoogleMaps .

Comments. This is a new distribution record of this species occurring in Nevada and a new host record for its occurrence on Datura . The length of C 1 and A 1 setal pairs are variable in this species. The puparia are easily overlooked usually found on the underside of the leaf.
