Tricholita Grote

Two undescribed species of Tricholita Grote came to our attention during this revision because of their similarity to Lasionycta . Tricholita can be distinguished from most Lasionycta by the white scales in the reniform spot. In the male genitalia of Tricholita the valve lacks a corona but has an adherent patch of long setae near the apex on the inner dorsal surface, the valve lacks the postsaccular flap characteristic of most Lasionycta , Psammopolia , and Lacinipolia , and the surface of the vesica lacks the band of cornuti that borders the wrinkled folding surface of the vesica in Lasionycta , Eriopygodes , and Lacinipolia , or covers the entire wrinkled surface in Psammopolia and Lasionhada . In the female genitalia the sclerotized surface of the ductus bursae does not extend onto the corpus bursae as in Lasionycta , Psammopolia , and Lacinipolia where it forms a sclerotized trough-like plate in the junction of the corpus bursae and ductus bursae. We take this opportunity to describe these species.
