Genus group Perugryllae Cadena-Castañeda & García García, 2020

Comments. This group was created to group the genera Perugryllus and Laureopsis . The Perugryllae Group is distinguished from the other groups of the subtribe by the following characteristics: tiny size (8–12 mm.); head as wide as pronotum, slightly wider than deep in frontal view; median lophi developed and bifurcated, never exceeding the lateral lophi; pseudepiphallic parameres in lateral view slim and with apex not obliquely truncate ( Cadena-Castañeda & García García 2020); tegmina of variable shape rounded and covering the abdomen or short and thick with reticulated venation; tympanum present or absent; stridulatory apparatus developed or not. These characters of the tegmina and tympana appear and disappear in the different taxa of Gryllidae and other families, varying even in closely related taxa ( Cadena-Castañeda et al. 2021b,c,d, Gorochov 2014, Randell 1964, Otte & Alexander 1983).

Laureopsis andinus n. sp. is the second known species of the genus and the fourth for the Perugryllae group. However, Laureopsis nauta Jaiswara, 2017 and L. andinus n. sp. are distinguished mainly by the feature of male genitalia. Also, we propose an identification key, including the new taxa recently described.
