Cryptic species are two or more organisms that are classified as single nominal species because they are at least superficially similar morphologically or are very difficult to distinguish. Neodexiopsis Malloch, 1920 is a genus of predaceous muscids occurring mainly in South America. Currently, the genus includes over 100 valid species. Neodexiopsis paulistensis Albuquerque, 1956 is distinguished from its congeners by the golden-yellow colour of the frontal vitta, frons, parafacial, gena, and d...
Cryptic species are two or more organisms that are classified as single nominal species because they are at least superficially similar morphologically or are very difficult to distinguish. Neodexiopsis Malloch, 1920 is a genus of predaceous muscids occurring mainly in South America. Currently, the genus includes over 100 valid species. Neodexiopsis paulistensis Albuquerque, 1956 is distinguished from its congeners by the golden-yellow colour of the frontal vitta, frons, parafacial, gena, and distal part of the 5th abdominal segment. We found a large series of female and male specimens with similar external colouration from several locations in Argentina, which we initially identified as N. paulistensis. However, we noted that several male specimens differed in the head colouration and the general shape of the abdomen. Through combined classical morphological studies, scanning electron microscopy images, and COI sequence analysis, we characterise two cryptic Neodexiopsis species, N. paulistensis and a new species, Neodexiopsis deltalar sp. n. We also present a more detailed description of the male and female terminalia of N. paulistensis, notes on its habitat, new records, and a discussion on the structures of the male terminalia.
