Schizoptera Fieber is a monophyletic and the largest genus of minute litter bugs (Hemiptera: Heteroptera: Dipsocoromorpha). Its current concept is supported by a recent molecular phylogeny and comprises nearly 90 described extant and two fossil species divided into four subgenera: Schizoptera (Cantharocoris), Schizoptera (Odontorhagus), Schizoptera (Schizoptera) and Schizoptera (Zygophleps). We here taxonomically revise the subgenus Schizoptera (Zygophleps), which so far contains Schizoptera unica McAtee & Malloch, 1925 from Guatemala and Schizoptera corallia Emsley, 1969 , Schizoptera simla Emsley, 1969 , and Schizoptera ultima Emsley, 1969 from Trinidad. The subgenus is diagnosed by the unique triangular shape of the posterior membranal cell. The following 36 species are here described: Schizoptera aculeata sp.n. , Schizoptera applanata sp.n. , Schizoptera bella sp.n. , Schizoptera biancae sp.n. , Schizoptera cassiae sp.n. , Schizoptera confusa sp.n. , Schizoptera costarriquenha sp.n. , Schizoptera cuspida sp.n. , Schizoptera ecuadoriana sp.n. , Schizoptera elegantissima sp.n. , Schizoptera emsleyi sp.n. , Schizoptera erosa sp.n. , Schizoptera erwini sp.n. , Schizoptera falcata sp.n. , Schizoptera familia sp.n. , Schizoptera furcata sp.n. , Schizoptera fuscodorsata sp.n. , Schizoptera hirsuta sp.n. , Schizoptera inaequalis sp.n. , Schizoptera inca sp.n. , Schizoptera kayi sp.n. , Schizoptera knyshovi sp.n. , Schizoptera magnifica sp.n. , Schizoptera mallochi sp.n. , Schizoptera mcateei sp.n. , Schizoptera orellanensis sp.n. , Schizoptera paraensis sp.n. , Schizoptera peruviana sp.n. , Schizoptera pichincha sp.n. , Schizoptera pinduca sp.n. , Schizoptera prima sp.n. , Schizoptera priva sp.n. , Schizoptera ramosa sp.n. , Schizoptera solitaria sp.n. , Schizoptera speira sp.n. , and Schizoptera stricta sp.n. The majority of species herein described were collected in Brazil, Costa Rica, and Ecuador, expanding the known distribution of the subgenus. We provide diagnoses, descriptions, photographs of habitus and subgenital plates, line drawings of diagnostic male genitalic features, and a distribution map. A key to species based on males is also presented. [ABSTRACT FROM AUTHOR]
