Pterygodermatites(Pterygodermatites)mexicanan. sp. (Nematoda: Rictulariidae), a parasite ofBalantiopteryx plicata(Chiroptera) in Mexico

Abstract

A new species of nematode, Pterygodermatites (Pterygodermatites) mexicana n. sp., is described based on specimens recovered from the intestine of the gray sac-winged bat, Balantiopteryx plicata (Chiroptera, Emballonuridae), from the Biosphere Reserve “Sierra de Huautla” in the state of Morelos, Mexico. This is the second species in the genus described from bats in the New World, since most of the rictaluriids reported in these hosts belong to the closely related genus Rictularia Froelich, 1802. However, members of Rictularia possess only a single oesophageal tooth at the base of the buccal capsule, whereas in the current nematodes three conspicuous oesophageal teeth are present. They are therefore included in Pterygodermatites Wedl, 1861. The new species is characterized by the presence of 23 small denticles on the periphery of the buccal capsule and by the presence of 40 and 66 pairs of cuticular processes in males and females, respectively. Additionally, males possess 3–4 ventral precloacal fan-like processes, and the cuticular processes of females are divided into 40 pairs of comb-like and 26 pairs of spine-like processes; the vulva opens on the level of approximately pair 40. The dorsally directed stoma and the 40 prevulvar cuticular processes makes it difficult to place the species in any of the subgenera present in the New World, yet characters correspond with the diagnosis of Pterygodermatites (Pterygodermatites) in the Mediterranean region and North Africa.

Checklist of Helminths of Bats from Mexico and Central America

“…This number represents 58% of the species of helminths recorded in Mexico. In addition, the diversity of helminths in Morelos includes 4 species that were described by our team (Peralta-Rodríguez et al, 2012;Caspeta-Mandujano et al, 2013Jiménez et al, 2014), which represents 8% of the diversity of helminths reported in chiropterans in Mexico. In comparison, the total number of bat species surveyed for helminths in Mexico includes 19 species, which roughly represents 14% of the total diversity of chiropterans present in this country.…”

“…Studies on helminth parasites from bats were continued by Caballero (1939;1940a,b;1942a,b;1943a,b,c), Caballero and Zerecero (1951), García (1995); Pérez-Ponce de León et al (1996), Guzmán-Cornejo et al (2003), Falcón-Ordaz et al (2006), Clarke (2008), Eslava (2005), Peralta-Rodríguez et al (2012), Caspeta-Mandujano et al (2013, and Jiménez et al (2014). Since 2008 the team of the Laboratorio de Parasitología of the Universidad Autónoma del Estado de Morelos has monitored helminths from bats in the State of Morelos (Martínez, 2009;Peralta, 2009Peralta, , 2012Tapia, 2011;Ojeda, 2013;Galindo, 2014;Juárez, 2015;Ramírez, 2015 and Juárez, pers.…”

Helminth parasites of some rodents (Cricetidae, Heteromyidae, and Sciuridae) from Zacatecas, Mexico

“…As a consequence of this dramatic shift, mammals in Mexico have become much more endangered (López-Ortega, Ballesteros-Barrera, Acosta, & Cervantes-Reza, 2012;Martínez-Meyer, Sosa-Escalante, & Álvarez, 2014), along with the helminth parasites these species harbor. Despite the efforts made to expand our knowledge on the biodiversity and natural history of mammals distributed in Mexico (Sánchez-Cordero et al, 2014), only 24% of the species richness has been examined for helminth parasites, and few studies have been conducted in north-central Mexico (e.g., Caspeta-Mandujano, Jiménez, Peralta-Rodríguez, & Guerrero, 2013;Guzmán-Cornejo, García-Prieto, Acosta-Gutiérrez, Falcón-Ordaz, & León-Paniagua, 2012;Jiménez-Ruiz, Rosas-Valdez, & Gardner, 2013;Jiménez-Ruiz, Peralta-Rodríguez, Caspeta-Mandujano, & Ramírez-Díaz, 2014;.…”

Helmintos del murciélago Macrotus waterhousii (Chiroptera: Phyllostomidae) en dos refugios de selva baja caducifolia en el municipio de Huetamo, Michoacán, México

“…Los primeros estudios helmintológicos realizados en murciélagos en México fueron llevados a cabo por Chitwood (1938) y Stunkard (1938), en varias especies que habitaban en cuevas de Yucatán. Sin embargo, el estudio de este grupo de parásitos en el país presenta muy poco avance y ha tenido como enfoque principal la taxonomía (Caballero, 1939(Caballero, , 1940Caballero y Zerecero, 1951;Caspeta-Mandujano et al, 2013, 2015Clarke, 2008;Espericueta, 2012;Falcón-Ordaz et al, 2006;García, 1995;Guzmán-Cornejo et al, 2003;Jiménez et al, 2014). Así, hasta el 2017 solo se cuenta con el registro helmintológico para 23 especies de murciélagos (Caspeta-Mandujano et al, 2017;García-Prieto et al, 2012).…”
