continued dorsally as a ridge continuing up to dorsal margin of frons
and midline of occiput; frons separated by distinct suture from occiput;
lower margin of front protuberance excavated and concave, filled with
thin scales tightly affixed to frons and hard to remove by brushing.
- Palpi with second segment about one and one-half times longer
than third; third segment oriented outwardly, giving apex of palpi a
downward curved appearance.
- Basal abdominal hair pencils and Stobbe's glands absent.
- Male eighth sternum u-shaped, without cephalad-lateral apodemes
and without an internal row of long hairs; eighth tergite a square to
rectangular, solid sclerite with a broad cephalad base.
- Male genitalia with lateral socii-like structures present
at the base of the uncus, each socus with a broad base and a projecting,
elongate triangular process; anal tube with a dorsal sclerotized plate.
- Juxta of male genitalia a heavily sclerotized, trapezoidal
- Male clasper very large consisting of a large, ovate plate
with a hook on its lower margin.
- Shape of aedeagus a small swelling at the base tapering to
a very long tail.
