Many setae on abdomen and head margin longer and conspicuously thicker than other short slender setae. Notch at apex of lobes short and barely perceptible, inner apical edges of lobes not divergent.... lapollai sp. nov.

Each anal lobe with about 30–35 dorsal setae. Anal ring situated about midway between base of anal lobes and base of notch between anal lobes.... iwokramae sp. nov.

– Second antennal segment 168–185 M m long, terminal segment bulbous, about 50 M m long. Dorsal and ventral inner edges of anal lobes clearly defined, each anal lobe with about 50 dorsal setae. Anal ring situated near base of anal lobes.. trinidadensis (Beardsley)
