Solenopsis weyrauchi

Nothing is known about the biology of .

Identification
A member of the Solenopsis saevissima species-group.

Distribution
Pitts et. al. (2018) - Solenopsis weyrauchi was previously known only from several widely spaced locations at high elevations in the Peruvian Andes. The holotype is from Cajamarca, Peru. As the new locality data suggest and as Trager (1991) predicted, the range of S. weyrauchi likely extends throughout the Andes, at least from Peru to Bolivia, but perhaps as far northward as Columbia and southward as Argentina and Chile.

Distribution based on Regional Taxon Lists

Description
Pitts et. al. (2018) - Head ovate to subrectangular. Head sculpture with small piligerous foveolae, ~0.01 mm in diameter. Median frontal streak present, sometimes consisting of 2 elongate darkened spots. Median ocellus in largest major workers absent. Mandibular costulae usually well developed throughout entire length, sometimes obsolescent near base. Mesonotum with 30 or more setae. Promesonotal suture in largest major workers gently curved medially, never projecting upward. Mesonotum weakly convex in lateral view. Propodeum sculpture glabrous posteroventral to spiracle. Postpetiole shape as high as or higher than broad. Postpetiole sculpture in posterior view with lower 0.50–0.75 transversely rugose, upper surface shiny with some piligerous foveolae present. Color of head, mesonotum and T1 maculation red yellow. Remainder of gaster black brown. Propodeum and dorsum of petiolar nodes yellow brown. Sometimes rear portion of head, frons around median streak, and pronotum yellow brown. T1 maculations with 2 small anterolateral spots.
