Diagnosis.

Archembia differs from the close related genera Calamoclostes and Ecuadembia by having mandibles with incisive teeth concentrated in the apex, anterior edge of Sm diffuse; apical cerci longer than basal cerci, and medial position of LC1dp ( Szumik 2004).

Composition and distribution.

According to Szumik (2004) Archembia includes six species, one is known exclusively from Bolivia, Archembia boliviana Ross, 2001 and the other five originally described from Brazil, but recorded in other countries: Archembia kotzbaueri ( Navás, 1925), Archembia bahia Ross, 2001, Archembia batesi McLachlan, 1877 also present in Peru, Archembia dilata Ross, 2001 also present in Argentina, and Archembia paranae Ross, 2001, exclusively from Brazil (see Catalog). Here, one new species is described from Brazil. Almost all the species of the genus were described by Ross (1971, 2001), and many of them were not illustrated. In some cases, the criteria used for the creation of a new species were differences on coloration, and a few of these species are now designated junior synonyms ( A. peruviana Ross, 2001 and A. lacombea Ross, 1971; see Catalog) or transferred to another genus ( Archembia arida Ross, 2001 from Ecuador now Ecuadembia arida (Ross); see Szumik 2004).

Thanks to the observations on Ross’s collection at CAS as well as material deposited at INPA, MZUSP, MCZ, and USNM we have a better understanding of the distribution of this genus, with one species being present in the Amazon basin ( A. batesi ), four species present in the Atlantic Forest ( A. kotzbaueri , A. dilata , A. bahia , A. paranae ), and a new species described from the Cerrado and Pantanal ecoregion.

Distribution.

South America.

Relationships.

Several cladistic analyses suggest that Archembia is a well-supported genus ( Szumik 2004; Szumik et al. 2008, 2019). Archembia is one of the basal genera of Archembiidae . The genera Ecuadembia and Calamoclostes are the sister group of Archembia they share the type B vein origin, a large anal area, the straight 10Lp1 with a spatulate apex and the Ep fused to the 10Rp1 ( Szumik 2004; Szumik et al. 2019); the three genera conform the subfamily Archembiinae .
