Proerginus Roewer, 1917 is a genus of the Neotropical family Cosmetidae from Haiti.

PlacementEdit

Originally placed in Cosmetidae Cosmetinae. Only the male of P. lineatus Roewer 1917 was described by monotypy with origin as "Haiti (Santo Domingo: Umgebung der Stadt)" [= Haiti/Dominican Republic, Santo Domingo: Surroundings of City)].

The genus is originally described with dorsal armature (small spines) on areas I and II, and stronger armature (large spines) on areas III & IV, none on free tergites, although type here tyoe described as rough granulate rows. Also notable are enlarged chelicerae (although female of P.lineatus is undescribed), robust hind legs (basal segments thicker than forelegs) and 6-segmented tarsus I with a 3-segmented thickened basitarsus.

Later Proerginus andinus Roewer, 1947 was added, from Peru (San Mateo) with similar dorsal armature. It is also listed for Ecuador.
