Synonyms and other taxonomic changes
Triatominae Jeannel, 1919
Explanation of Names
Type-genus: Triatoma Laporte, 1832.
Numbers
ca. 120 spp. in 14 genera and 5 tribes worldwide (all but 12 s. Asian spp. are restricted to the Americas)(1); 11 spp. in 2 genera north of Mexico (one Paratriatoma spp., others in Triatoma)
Size
5-45 mm (most spp. 20-28 mm)(1). In the US, individuals range from 13-33 mm.
Identification
The subfamily is characterized by hemelytra without a quadrate cell, antennal segments not subdivided, transverse constriction of pronotum at or before middle, rostrum more or less straight (not arcuate) and antenniferous tubercles projecting laterally from head.

The subfamily was revised in a exceptional monograph by Lent & Wygodzinsky (1979)(2). This is undoubtedly the most important work in the vast sea of Triatominae literature, particularly regarding identification of the group's taxa.
Range
mostly New World (from s. Argentina to central US) + 12 spp. in s. Asia and a single pantropical sp. (Triatoma rubrofasciata) in Africa(1)
Habitat
Sheltered habitats used by the hosts(1) ie caves, logs, nests, human habitations, etc.
Food
Blood of various tetrapods (mammals, birds, reptiles, and amphibians)(1).
Remarks
12 spp. in 3 genera (Triatoma, Rhodnius, Panstrongylus) are considered major vectors of Trypanosoma cruzi (the causative agent of Chagas Disease), but none of those occur in our area(1).
