SUMMARY
Hybobathus was a genus described by Enderlein (1938) for his species quadrilineatus. Thompson (pers. com.) consideres quadrilineatus as a member of the lineatus group sensu Hull (1949). Hybobathus species are distinguished by linear, vittate pattern upon the petiolate abdomen. They are light yellow flies with scutum yellow laterally, yellowish-green pollinose medially, with wing light greenish yellow and legs yellow.
O. amabilis is somewhat similar to Ocyptamus flavipennis Wiedemann, with narrower abdomen and fewer linear vittae. Hull (1943) placed this species in the lineatus group.
O. amabilis has second abdominal tergum slightly constricted in the middle, about twice as long as its greatest width or longer; sides of second tergum yellow on basal two-thirds. Third and fourth terga with sublateral vittae incomplete, though reaching through most of the tergum and curved or attenuate (Hull 1943).
