A new flesh fly species (Diptera: Sarcophagidae) parasitic on leptodactylid frogs

Abstract

Here we describe a new species of sarcophagid fly reared from larvae found feeding on three species of leptodactylid frogs collected in subtropical Corrientes Province in northeastern Argentina. Our species description is based on adult male and female external morphology and genitalia. Adult males and females of the new species were associated with certainty because all specimens studied were reared from single clutches of larvae on each of three infested frogs. Thus, adult males and females reared from each clutch were siblings that emerged almost simultaneously. The paper provides line drawings, high-resolution photographs, and SEM images to aid in identifying Lepidodexia (Notochaeta) adelina sp. nov. and to distinguish the new species from its closely related congeners. We include brief notes on the host species and on larval feeding behavior of L. (N.) adelina. This is the first and only species in the genus Lepidodexia reported to parasitize leptodactylid frogs. Further, our observations reported here are the first to fully document a completed life cycle by sarcophagid fly larvae on three different species of leptodactylid frogs and the only well-documented case of myiasis of an amphibian in Argentina.

Museomics and protein-encoding ultraconserved elements illuminate the evolution of life history and phallic morphology of flesh flies (Diptera: Sarcophagidae)

“…Evolution of sarcophagid life histories and male terminalia traits Since I was interested in the evolutionary trajectory of life histories and male terminalia in the subfamily Sarcophaginae, I inferred ancestral character states using the dated phylogeny. Biological data were compiled mostly from the literature (3,4,72,(162)(163)(164)(165)(166)(73)(74)(75)(76)(77)(78)(79)(80)(81)5,(82)(83)(84)(85)(86)(87)(88)(89)(90)(91)6,(92)(93)(94)(95)(96)(97)(98)(99)(100)(101)9,(102)(103)(104)(105)(106)(107)(108)(109)…”

Intraocular nematode and other parasites associated with Physalaemus albonotatus (Anura: Leptodactylidae) from Corrientes, Argentina

“…stenocotyle (Cohn, 1902) (metacercariae) (Hamann and González 2009). Mulieri et al (2018) reported the presence of an ectoparasitethe larvae of the sarcophagid fly, Lepidodexia (Notochaeta) adelina Mulieri, Schaefer, Duré and González, 2018-in this species. We report three novel parasites in a Physalaemus albonotatus collected in Corrientes (Argentina)-viz., a nematode larva of the order Rhabditida in the eye, and cystacanths and cosmocercids in the mesentery and the large intestine, respectively. On the morning of 06 December 2017, one of authors (EFS) captured a female P. albonotatus (Figure 1 A, B) in the 8-ha compound of the Centro de Ecología Aplicada del Litoral (CECOAL); this fi eld station in the suburbs of the city of Corrientes (27°29'33.89" S, 58°45'33.63" W) is operated by the Consejo Nacional de Investigaciones Científi cas y Técnicas (CONICET) of Argentina.…”
