DIAGNOSIS: Male protarsomere-2 with 0—2 (mostly commonly 1) sclerotized teeth on the sex comb; inner lobe of ventral epandrial lobe with fine, irregular furrows. Acrostichal setulae in 6 rows.
1. Male testes bright yellow or orange to commonly red.
2. Ventral epandrial lobe with an inner lobe closely adpressed to surstylus.
3. Males with sex combs on protarsomeres ta 1 and ta 2 (rarely absent on ta 2). 4. Aedeagus with pair of lateral valves.
5. Male protarsomere ta 2 with 2 or fewer teeth.
6. Facial carina narrow, shallow, and short, without flattened edge.
7. Base of inner lobe of ventral epandrial lobe with fine, irregular furrows. 8. Spermatheca with well developed apical indentation extending into end of sleeve. 9. Male protarsomere ta 2 with 0 or 1 tooth (sometimes tooth is very small). 10. Base of inner lobe of ventral epandrial lobe with dense microtrichia.
11. Testes coiled (vs. ellipsoid or folded just once).
12. Male protarsomere ta 1 with numerous (7–18) teeth.
13. Tooth on male ta 2 minute.
14. Male frons with fine, silvery shagreenation.
15. Spermathecal capsule squat, width>1.5× the height.
16. Male protarsomere ta 1 signficantly shorter than ta 2.
17. Aedeagal valves with micropapillae.
18. Acrostichal setulae in 8 rows (vs. 6).
