Stenopelmatus, Burmeister, 1838

Cadena-Castañeda, Oscar J., Rodríguez, William David & Navarrete-Heredia, José L., 2019, Orthoptera (Ensifera & Caelifera) collected using carrion traps in a Quercus forest in Jalisco, Mexico, with description of a new genus and a new species (Trigonidiidae: Nemobiinae), Zootaxa 4550 (3), pp. 401-415 : 406

Stenopelmatus sp. 1

( Fig. 3C )

Commonly known as "boyish" or Jerusalen Crickets ( Weissman, 2005), are peculiar Orthoptera with fossorial habits, eyes narrowed, abdomen inflated and separated from the thorax by a small pedicel ( Cadena-Castañeda & Torres, 2013) are the closest group to rolling leaf crickets or gryllacridines ( Song et al., 2015; Vandergast et al., 2018). To date there are 20 valid pecies of Stenopelmatus Burmeister ; discontinuously distributed from Canada to Costa Rica ( Burmeister, 1838; Gorochov & Cadena-Castañeda, 2016; Cigliano et al. 2018). For Mexico there are registered S. lycosoides Walker , S. calcaratus Griffini and S. lessonae Griffini (no precise location); S. guatemalae Brunner von Wattenwyl (Chiapas, but also registered to Guatemala and Nicaragua). S. histrio Saussure and S. minor Saussure , (Veracruz); S. nietei Saussure , (Veracruz, Hidalgo, Tamaulipas and Coahuila); S. longispinus Brunner von Wattenwyl (Sinaloa) ; S. talpa Burmeister , (initially without precise locality but recently recorded by Gorochov & Cadena-Castañeda, 2016, for the states of Oaxaca, State of Mexico and Veracruz) and S. fuscus Haldeman , which is registered for the northeast Mexican territory. However, the photographs of S. fuscus found in reports in which the species is reported, such as those of Berumen et al. (2006) and Barrientos-Lozano et al. (2013) do not confirm? to the original description and most likely were erroneously identified, like the previous two publications, the record for this species in Mexico is doubtful ( Weissman, 2001; Gorochov & Cadena-Castañeda, 2016; Cigliano et al., 2018).

These individuals were collected from May to December. Females were trapped the most in carrion traps. The morphospecies studied here is very similar to S. minor Saussure by its small size and black color, according to Weissman (2001). Numerous species await description by Dr. David Weissman, commenting only that only on the east coast of the United States there may be about 50 undescribed species morphologically similar. Species of Stenopelmatus live under the sand or soil (lowland species and semi-desert areas) but almost nothing is known about the species that inhabit the mountains, some individuals of this morphospecies were seen in galleries or decaying logs, are omnivorous habits and subjected to stress can become cannibalistic. At the request of Dr. David Weissman this species is not described.
