This individual was identified as gloverii by examining the antennas. On gloverii sensory hairs on antennal pectinations are somewhat appressed and do 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 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.
