Mid, hind coxae touching basally, slightly separated distally, hind coxae large, elongate, more or less parallel-sided, no distinct armament visible; hind femur almost regularly elliptical, 4.4 mm long, 1.9 mm wide (length to abdominal segment width ca. 1:2.3), other leg segments incomplete. Wings damaged, incompletely known. Forewing length 13.9 mm, maximum width 4.4 mm or slightly more, length/width> 3.1; membrane possibly lightly infuscate behind R+M; pterostigma dark; R+M shorter than 1-M; maximum length of cell 2r shorter than 3r; 2r-rs slightly longer than Rs between 2r-m, 2r-rs, joining cell 3rm slightly before its middle; 2r-m straight, joins Rs distal to 2m-cu joining M, well distal 2mcu; 1-M almost straight, sub-parallel to 1m-cu; 3r-m incompletely preserved, its form obscure; cell 2mcu with M apparently subequal to 1m-cu; 2m-cu incompletely preserved, apparently slightly curved toward base; cu-a interstitial; anal cells not preserved.
