Genus Ocyptamus
Synonyms and other taxonomic changes
the taxonomy adopted here follows that proposed in(1)(2), whereby several nearctic spp. formerly treated in Ocyptamus have been transferred to other genera (Hybobathus, Pelecinobaccha, Pseudoscaeva) to avoid paraphyly with regards to Eosalpingogaster and Toxomerus(1)(Mengual 2012)
Explanation of Names
Ocyptamus Macquart 1834
10 spp. in our area(2), 17 total [if defined broadly, ~300 spp. total](1)
9-14 mm
New World
Some tropical species have aquatic larvae (Rotheray et al. 2000)
Larvae prey on aphids, coccids, etc.
