AI Article Synopsis
- Metadelphis tkachi n. sp. is a newly identified species found in the gall-bladder of the bat Molossus molossus in the eastern Amazon region of Brazil.
- Key features that set this species apart include lobed tandem testes and elongated clusters of vitelline follicles that start at the seminal receptacle.
- The study also provides new morphological information on a related species, Metadelphis lenti, revealing variations within the species using advanced microscopy techniques.
Article Abstract
Metadelphis tkachi n. sp. is described based on material from the gall-bladder of Molossus molossus (Pallas) (Chiroptera: Molossidae) in the Brazilian eastern Amazon. The main differentiating characters of the new species include lobed, tandem testes and elongated clusters of vitelline follicles commencing at the level of the seminal receptacle. The new species can be distinguished from Metadelphis lenti (Santos & Gibson, 1998) and Metadelphis apharyngotrema (Marshall & Miller, 1979) by the shape and position of the testes; from Metadelphis evandroi Travassos, 1944 by having tandem, lobed testes and shorter clusters of vitelline follicles; from Metadelphis compactus Travassos, 1955 by having tandem testes and more elongated clusters of vitelline follicles, and from Metadelphis alverangai Travassos, 1955 by having smaller testes and body, and vitellarium with large follicles. New morphological data are reported for M. lenti based on light and scanning electron microscopy; intraspecific variation was observed.
