Cryptothelea gloverii
Shreveport, Caddo Parish, Louisiana, USA
May 16, 2015
This individual was identified as gloverii by examining the antennas. On gloverii sensory hairs on antennal pectinations are somewhat appressed and their length does not exceed the diameter of the pectinations. On nigrita, the length of these hairs are 1.5 to 2 times greater than the diameter of the pectinations. See Bagworm Moths of the Western Hemisphere by Donald R. Davis, (http://www.biodiversitylibrary.org/page/7892046#page/6/mode/2up). See diagrams of their antennas on page 217: fig 368 (nigrita) and fig 369(gloverii). See text for gloverii on page 59; for nigrita on page 56. There is a key to the genus on page 51.

That's what we needed
Jeff, the criterion you discovered should solve our problem of separating nigrita from gloveri on photos - all that's needed is sufficiently high resolution. Maybe you can persuade an editor to add the information you provide to the species pages (or become an editor yourself and do it). Thanks!
