Desmiphora (Desmiphora) cirrosa Erichson, 1847

Desmiphora cirrosa Erichson, 1847: 147.

Desmiphora similis Breuning, 1943: 46.

Desmiphora cucullata Thomson, 1868: 104. Syn. nov.

In 1847, Erichson described Desmiphora cirrosa based on a female from Peru, collected by Tshudi. Subsequently, in 1868, Thomson described Desmiphora cucullata from a female collected in South Brazil (Oberthür Collection), and mentioned that it may be only a variation of D. cirrosa. Additionally, some of the differences pointed out by him do not exist when comparing the holotypes (see photographs of both type specimens at Bezark 2019) (for instance, the general color). Comparing photographs of both holotypes, it is possible to see that, apparently, D. cucullata does not have the tuft of setae on the dorsobasal area of the elytra, as well as the tuft of setae on dorsodistal third area of the elytra. It appears that only the tufts near apex are present. However, Thomson did not mention them, or the presence of the tufts on the distal area, which are, evidently, present.

Based on examination of the two type specimens and a large series of specimens in the ACMT (Mexico; Tamaulipas to Quintana Roo, Costa Rica, Bolivia, and Paraguay), LGBC (Mexico; Chiapas, Costa Rica, Panama, Ecuador, and Paraguay) and MZSP, the synonymy is confirmed. The recently collected material shows some variation in the spotting of the basal antennal segments and some differences in the preapical elytral markings, and all specimens have the extensive tufting and uniform coloration; they all appear to be the same species.
