Etymology.

The species name is a noun in apposition derived from the typical dance of the Carnival of Pernambuco state.

Diagnosis.

Cyrtogrammomma frevo sp. nov. can be recognized by the presence of a pattern of lateral stripes and central dots on the dorsal face of the abdomen (Figs 10A, 12A). Furthermore, it differs from C. monticola by having the PMS shorter (Fig. 11A, B) and from C. raveni by having a few cuspules (fewer than five) concentrated in the anterior half of the labium (see Mori and Bertani 2020, fig. 338). Males differ from C. monticola by the presence of a “spoon-shaped” tip on the embolus (Fig. 10H-L). Females can be distinguished by the spermathecae receptacle with short ducts (Fig. 12D).
