In this group, I tentatively include a few closely related species which have a small or very small inner tympanum, long tegmina reaching or almost reaching the abdominal apex (all the specimens listed above are macropterous, but hind wings in male from Honduras somewhat less long than in other specimens, and in some specimens, these wings are torn off or removed after flight peri- od), 33–50 teeth in the stridulatory vein, and male genitalia practically identical to those of A. caraibeus .

Anurogryllus muticus and A. celerinictus are distinguished from each other by their acoustic behavior, but the morphological characters used for their separation ( Walker 1973) are significantly overlapping and do not give possibility for exact determination of my material; for example, my specimens from “San Jose” in Cuba probably belong to A. celerinictus , because they are rather large, and this species is also large and distributed from Southern Florida to Jamaica and Grand Cayman.

Anurogryllus fuscus from Peru and A. comptus from “Constancia” ( Walker 1869) are rather dark in colouration and insufficiently described, and the latter name is usually considered as a synonym of A. muticus . But they also may be subspecies of this species or closely related species; my specimens from Honduras, Paraguay and Fuerte de Momon in Peru are also rather dark, and some of them may belong to these subspecies or species. Anurogryllus patos (South Brazil) is similar to my males from Nicaragua, Colombia as well as the locality between Puente Itaya and San Juaquin in Peru in the male tegmen with long apical area (1.3–1.4 times as long as mirror), but this species differs from them in more transverse mirror (almost 1.2 times as wide as long; vs. 1–1.1 times as wide as long). My male from Rio de Janeiro has distinctly shorter apical area and less transverse mirror in the male tegmen than in A. patos , and differences of this male as well as A. patos from Argentinian A. clarazianus is also unclear.

Finally, A. bebeei from Trinidad I. and A. angustulus insufficiently described from the other Caribbean Islands are more or less similar to all my others specimens of this group having their body dorsally from light brown with brown spot between ocelli to brown with dark brown head dorsum, mirror in the male tegmen almost not transverse, and apical area of this tegmen less long than in A. patos . Moreover, the type material of A. muticus from Surinam is also insufficiently studied. Thus, division of this complex into species and subspecies is work for the future.
