Diagnosis.

Embolyntha can be distinguished from other Archembiidae by Sm with anterior margin membranous, 10Lp1 simple and starting at inner caudal angle of 10L, 10Lp1 leaf-like with many longitudinal carinae ( Szumik 2004).

Composition and distribution.

Embolyntha has two species ( Szumik 2004): Embolyntha brasiliensis (Gray, 1832) from Brazil (without any specific location) and Embolyntha guyana (Ross, 2001) from Guyana and Brazil (see Catalog for details). In addition, one new species from Brazil is described below.

Distribution.

South America.

Relationships.

Argocercembia was synonymized with Embolyntha by Szumik (2004) because of the minimal differences between them. Both taxa appeared grouped together by sharing 10Lp1 shape, a small medial bladder in males, and LC1dp in a medial position, both forming a well-supported group. In the higher classification of the Order ( Szumik et al. 2008: 927), the genus remains monophyletic and as sister group of the monotypic genus Ochrembia . Finally, these groups remain supported in a more recent study ( Szumik et al. 2019: 9) where new evidence from ultrastructure traits on leg chaetotaxy as well as the chordotonal organ were included.
