Subgenus Eupeucestes Hebard, 1927

Type species (in original binomen): Locusta crassifolia Haan, 1843 [= C. (E.) citrifolium (Linnaeus, 1758) View in CoL ], by original designation.

Brief diagnosis. Upper rostral tubercle approximately as wide as lower one ( Fig. 106 View Figs 106–117 ); pronotum with lateral lobes as in Cnemidophyllum View in CoL s. str. but with high dorsolateral keels (these keels almost as high as in Fig. 113 View Figs 106–117 ); middle and hind tibiae with slightly widened proximal portions ( Figs 99, 100 View Figs 83–105 ); male abdominal apex with moderately long and more or less bilobed posteromedian process on last tergite; female abdominal apex practically as in Cnemidophyllum View in CoL s. str. ( Fig. 133 View Figs 126–144 ).

Composition (in original binomens). Only one species – Gryllus (Tettigonia) citrifolius Linnaeus, 1758 [= Locusta crassifolia Haan, 1843 , Peucestes cristatissimus Brunner-Wattenwyl, 1878 View in CoL and Peucestes lutescens Piza, 1950 View in CoL , all synonymized by Emsley (1970)] (described from “Indies” (Emsley’s neotype from West India: Trinidad), “Java” (probably erroneous label), French Guiana and southeast Brazil, respectively; distributed from Central America and Trinidad to Argentina and Paraguay).

It is necessary to note that Peucestes striolatus Brunner-Wattenwyl, 1878 View in CoL was considered by Emsley (1970) as an additional synonym of C. (E.) citrifolium View in CoL (his opinion was probably based on the note by Karny (1920) about possible synonymy of P. striolatus View in CoL with L. crassifolia ), but in OSF, P. striolatus View in CoL is placed in the subgenus Steirodon (Peucestes) View in CoL without any explanation.
