Comment. The terminals here representing the genera of Metergininae are only a short summary of the real diversity of this group. As demonstrated above, there is a subgroup of Andean species in the genera Rhaucus , Rhaucoides and Rhauculus , which should be modified to accommodate them. A new combination in Rhaucoides is formally proposed below in this section. The other clade comprises species from Mexico, Central America and the Greater Antilles.

Diagnosis: Robust cosmetids with strong legs, may vary in length. DS alpha-type with large to moderate coda. Areas I–IV with paramedian ornamentation. Area V may bear a transversal yellow stripe. Femora III and IV with spines or large tubercles in a ventral portion (except for Poecilaemula Roewer, 1912 ). Inflated cheliceral hand in males, with basal triangular tubercle in movable hand. Pedipalpal tibiae widest at the middle and with a prolateral flap along the inner side. Macrosetae D2 shifted to distal (except in Rhaucus ). Stylar barbs present.

Type genus: Meterginus Pickard-Cambridge, 1905 .

Included genera (from the analysis): Arucillus Šilhavý, 1971 ; Erginulus Roewer, 1912 ; Meterginus Pickard-Cambridge, 1905 ; Poecilaemula Roewer, 1912 ; Rhaucoides Roewer, 1912 ; Rhauculus Roewer, 1928 ; Rhaucus Simon, 1879 ; and Trinimontius Šilhavý, 1970 . Other included genera (according to the present diagnosis): Cumbalia Roewer, 1963 and Rhauculanus Roewer, 1928 .

Combined distribution: From Mexico to Peru, including Central America, northern Andes and Greater Antilles ( Fig. 8 ).
