Abstract

Cardiosciara Shah, Heller & Huang gen. nov., formerly included within Cratyna Winnertz, 1867, is described and distinguished based on clear morphological and genetic differences. Diagnostic features of the new genus include long maxillary palpi, a setose posterior pronotum, an undifferentiated tibial organ, bare posterior wing veins, and male genitalia with a distinctive tegmen that is deeply notched apically with a dark, often heart-shaped overlapping structure. Four new species are described: Cardiosciara amoris sp. nov., C. bicordis sp. nov., C. digna sp. nov., and C. ignota sp. nov. In addition, a previously published species, Cardiosciara salomonis (Mohrig & Mamaev) comb. nov., is transferred here. The distinct status of the new species is supported by both morphological characteristics and sequence data from cytochrome oxidase subunit I (COI) gene obtained through DNA barcode analysis. A checklist of all currently known species of Cardiosciara gen. nov. is provided.
