Dipetalogaster, a genus of Triatominae, the kissing bugs, has only a single species, Dipetalogaster maxima (often misspelled as "maximus", e.g.[1]), which is found in the Mexican state of Baja California Sur.

Originally the blood-sucking Dipetalogaster lived in crevices in rocks where it typically fed on lizards,[1] but following human growth in its range it now also commonly feeds on humans and domestic animals.

[2] Dipetalogaster is routinely infected by the Chagas disease parasite Trypanosoma cruzi.

[5] The bite of Dipetalogaster is essentially painless because of the very thin mouthpart apparatus (about 0.02 mm or 0.8 thou, far less than a typical hypodermic needle) and the anaesthetic effect of its saliva.

[5] At up to 5 cm (2.0 in) in length, Dipetalogaster is the largest species of the subfamily, but otherwise it resembles the better-known Rhodnius prolixus.
