Comparative analysis of the male reproductive accessory glands of bat species from the five Brazilian Subfamilies of the family Phyllostomidae (Chiroptera)

This study aimed to morphologically characterize and compare the male reproductive accessory glands (RAGs) of bats belonging to the five Brazilian subfamilies of the family Phyllostomidae (Carollia perspicillata—Carollinae; Desmodus rotundus—Desmodontinae; Glossophaga soricina—Glossophaginae; Phyllostomus discolor—Phyllostominae and Platyrrhinus lineatus—Stenodermatinae). The study demonstrated that the RAGs of phyllostomid bats were comprised of a pair of extra‐abdominal bulbourethral glands and an intra‐abdominal complex, composed of paraurethral glands and a prostate with two (Desmodontinae and Stenodermatinae) or three (Carollinae, Glossophaginae and Phyllostominae) different regions, with the absence of the seminal vesicles; this pattern possibly evolved from a process of compaction of the prostatic regions from an ancestor with three regions.
