Virgin Islands (St. John [type locality, as 'St. Jean'], Jost Van Dyke, St. Croix, Tortola, Guana, Beef, Virgin Gorda, St. John, Beef, Great Camanoe)
This species (along with A. brevifrons and A. impressa) was moved to Bulldolonia Gnezdilov, 2012 by the author of the genus.This species is very similar to A. brevifrons, which was described from Puerto Rico but subsequently attributed to the Virgin Islands.Acanalonia depressa and A. brevifrons are possibly the same species.Fennah (1949: 60) noted :
"Two males taken by the writer on Jost Van Dyke (Feb. 18, 1944). These specimens differ from Melichar's description and figure only in the profile of the head. According to Dr. Paul Oman, material from St. Thomas and St. Croix differs from the Puerto Rican A. brevifrons Muir in being smaller, and having the vertex more sharply declivous, the portion of the head in front of the lateral frontal carinae shorter, the costal margin of the tegmina more strongly curved and the anterior portion of the apical margin more broadly rounded. The male genitalia of the specimen before the writer are very close to those of A. impressa Metc[alf]. and Bruner. The species is evidently polytypic and the taxonomic relationship of its members might be most appropriately expressed by regarding brevifrons and impressa as geographical subspecies."
