New Philopotamidae (Insecta, Trichoptera) from Ecuador: seven new species and updated country checklist

Abstract:

Seven new species in the caddisfly family Philopotamidae are diagnosed, described, and illustrated from Ecuador, three in the subfamily Chimarrinae: Chimarrhodella spinosasp.nov.,Chimarra(Otarrha)buglassp.nov.,Chimarra(Chimarra)buenaventura sp. nov., and four in the subfamily Philopotaminae: Sumacodella grijalvai sp. nov., Wormaldia nilssoni sp. nov., Wormaldia insolita sp. nov., and Wormaldia milpe sp. nov. The species are rare and endemic to the country. In addition, an updated distributional checklist of the 60 species of philopotamids now known from the country is presented. Thirty-eight, or 64%, of these species are endemic. Finally, the Chao 2 estimator, based on 126 localities, suggests that the expected number of philopotamid species is 60 (SD 9), which implies that almost all the species present in the country are known.
