Based on the phylogeny of the three combined loci (mtSSU, LSUand RPB2), Lumbsch et al. (2014) provided an updated phylogeny of the lichenized family Graphidaceae and revealed a new genus Paratopeliopsis belonging to the tribe Thelotremateae. Later, Paratopeliopsis was formally introduced by Mercado-Diaz et al. (2014), with P. caraibica as the type species. Paratopeliopsis caraibica was found in the shaded understory of a Palo Colorado Forest in El Yunque National Forest, growing among mosses on the trunk of Cyrilla racemiflora (Mercado-Diaz et al. 2014). Paratopeliopsis resembles a miniature Topeliopsis but differs in the distinctly farinose thallus and the small brown ascospores, which are not closely related to Topeliopsis but belong to the tribe Thelotremateae (Lumbsch et al. 2014Mercado-Diaz et al. 2014). No other species have been introduced to this genus, which remains monotypic.

            Type species: Paratopeliopsis caraibica Mercado-Díaz, Lücking & Parnmen

Other accepted species: This genus is monotypic.
