Blastobasis pulchella (Dietz, 1910) - No Common Name

Superfamily: Gelechioidea Family: BlastobasidaeSubfamily: BlastobasinaeTribe: BlastobasiniP3 Number: 421770.00 MONA Number: 1167.00
Comments: Blastobasis is a taxonomically difficult genus, with several undescribed species in North America. There appears to be several poorly resolved species complexes within this and closely related genera. A comprehensive revision of the genus is needed.
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIFTechnical Description, Adults: Dietz (1910)                                                                                 
Adult Markings: The following is based in part on the description by Dietz (1910). The labial palp, antenna, head, and thorax vary from light tannish-brown to darker shades of brown. The forewing has a rather wide, silver white fascia at one-third that is straight. It is sharply defined posteriorly by heavy, dark brown shading that fades posteriorly before reaching a dark discal spot at about the middle of the wing. There are two additional spots at the end of cell at about three-fourths, but these are often completely obscured by a straight, dark brown fascia. The middle and apical regions are more or less suffused with brown and sprinkling with varying concentrations of white scales. The cilia are similar in color to the ground and there is often some fine darker mottling at the termen. The hindwing is pale gray and dusted with fuscous. The legs are brownish with white banding on the tarsi. Pigritia murtfeldtella is similar, but lacks the conspicuous dark spot at mid-wing and the dark fascia at three-fourths. This species also has poorly developed palps that are not visible when viewed from above. Some of the Holcocera species are also similar, but the whitish fascia at one-third typically doesn't reach the inner margin, and the dark fascia at three-fourths is missing (typically, pairs spots are present instead).
Wingspan: 8.5 mm (Dietz, 1910)
