Subgenus Sivabezzia Remm, 1974

Type species

Bezzia campanai Clastrier, 1962 ; by original designation.

Diagnosis

Fore femur with 2–4 ventral spines. Male flagellomere 10 elongate, longer than 11–13. Gonocoxite massive; gonostylus well developed, simple; aedeagus composed of small lamella and long median process, which is bent dorsally and directed posteriorly. Female with 2 large seminal capsules, more or less similar in size, both with long necks that are narrowed proximally.

Remarks

Females of B. melanoflava Clastrier, 1958 and B. pachypyga Remm, 1974 are very similar, with only slight differences in the shapes of their seminal capsules. In B. melanoflava they are broadest near the middle portion, whereas in B. pachypyga the widest part is near the proximal portion.
