Trogoptera guianaca Schaus, 1928

( Figs. 23 , 30 )

Type locality. Brazil: Amazonas ; Venezuela: Merida ; French Guiana [ USNM syntype, French Guiana, examined, French Guiana specimen designated here as lectotype]

The specimens from Trinidad that we have examined, closely match a male syntype of T. guianaca from French Guiana, and thus we assign the specimens from Trinidad to this species. As noted earlier, there is a strong similarity between the Mimallonidae fauna of French Guiana and that of Trinidad.

Considering the fact that T. guianaca was described from an unspecified number of specimens from Brazil, Venezuela, and French Guiana, there is uncertainty surrounding the identity of this species. Therefore, we designate a lectotype for T. guianaca using a syntype in the USNM from French Guiana with the following labels: Trogoptera guianaca type Schaus/ Genitalia Slide By C.H. # 23 USNM 86051/ ♂ genitalia slide, 24 Mch.’28 C.H. #23/ Avril [April]/ Guyane Françse [ French Guiana], Nouveau Chantier, Collection Le Moult/ Dognin Collection/ [Lecto] Type No. 33568 U.S. M.N./ USNM-Mimal: 1045/ LECTOTYPE ♂ Trogoptera guianaca Schaus designated by St Laurent and Cock, 2017 [red handwritten label]. This designation enables us to more accurately identify the specimens from Trinidad that we attribute to T. guianaca , and more importantly, offers stability as to the identity of the species T. guianaca .

The few specimens are from diverse habitats in Trinidad: suburban (Curepe), lowland forest (Inniss Field), and high forest (Morne Bleu Textel Installation).
