A new genus and species of Chamaemyiidae (Diptera: Lauxanioidea) from South America feeding on Ceroplastes wax scales (Hemiptera: Coccidae), and status of the genus Ortalidina as a chamaemyiid

摘要

A new genus and species of Chamaemyiidae (Diptera: Lauxanioidea) is described and illustrated, namely Chamaeleucopis, gen. nov. (type species Chamaeleucopis trevas, sp. nov.), a predator of Ceroplastes wax scales on guava from Brazil. In addition, thepreviously unrecognized genus Ortalidina Blanchard 1852 (type species Ortalidina cellularis Blanchard 1852), mainly from the Neotropics, is recognized as a chamaemyiid, and is the senior synonym of Toropamecia Cogan 1978, syn. nov. (type species Acrometopia punctata Coquillett 1902). The species Toropamecia grossa Cogan 1978, syn. nov., is synonymized under Ortalidina cellularis. All species therein become new combinations within Ortalidina, including (in their original combinations) Acrometopa australis Malloch 1933, comb, nov., Acrometopia maculata Coquillett 1902, comb, nov., Acrometopia punctata Coquillett, comb, nov., Toropamecia apaxa Cogan 1978, comb, nov., Toropamecia caribbea Cogan 1978, comb, nov., Toropamecia hendeli Cogan 1978, comb, nov.,Toropamecia hyalipennis Cogan 1978, comb, nov., Toropamecia jujuyensis Cogan 1978, comb, nov., Toropamecia longipennis Cogan 1978, comb, nov., Toropamecia macalpinei Cogan 1978, comb, nov., Toropamecia multipunctata Cogan 1978, comb, nov., Toropamecia nigripalpis Cogan 1978, comb, nov., Toropamecia reducta Cogan 1978, comb, nov., Toropamecia smithi Cogan 1978, comb, nov., Toropamecia veenota Cogan 1978, comb, nov., Trigonometopus reticulatus Johnson 1913, comb. nov. A habitus photo of the primary typefor each species of Ortalidina is provided.
