New species of Fannia Robineau-Desvoidy (Diptera: Fanniidae) from Colombia

Yesica Durango

Manuel A. Ramírez-Mora

Abstract: Fannia Robineau-Desvoidy is a genus of calyptrate Diptera that comprises 89 Neotropical species, of which only 23 occur in Colombia. Based on male characters (including terminalia), two new species from the Department of Antioquia (Fannia colazorrensis sp. nov. and Fannia laclara sp. nov.) are described. Illustrations of the male are presented.

The genus Fannia is the most representative of the Fannidae family of true flies with worldwide distribution. Some species are attracted to decomposing materials and live vertebrate animals, which makes them important in forensics, medical and veterinary fields. However, identifying Fannia species can be difficult due to the high similarity in the external morphology of females and limited descriptions and morphological keys. Herein, molecular markers could provide a complementary tool for species identification. However, molecular identification has still limited application since databases contain few data for neotropical species of Fannia. This study assessed the potential of two molecular markers, the COI‐3′ region and internal transcribed spacer 2 (ITS2), to differentiate 10 putative species of the genus Fannia from Colombia using distance‐based and tree‐based approaches. The partial ITS2 and/or COI‐3′ regions allowed molecular diagnosis of six species, while pairs of species Fannia colazorrensis + F. dodgei and F. laclara + F. aburrae are conflicting. Although these results might suggest that conflicting pair species are conspecific, consistent morphological differences between males do not support this hypothesis. The lack of differentiation at the nuclear and mitochondrial molecular markers for the conflicting species may be due to incomplete evolutionary lineage separation, hybridization, or introgression events. In addition, sexual selection on male morphological traits before species‐specific differences in molecular markers emerge may partially explain the results. Our study provides a valuable dataset to identify and confirm some Fannia species molecularly. Further, they could be used to associate females and immature stages with their conspecifics as a baseline to deep into their biology, ecology, distribution and potential applications in forensic and medico‐veterinary entomology.
