Pheidole carinata  HNS  new species

Types INBio.

Etymology L carinata  HNS  , keeled or ridged, referring to the ridge-like mesonotal convexity in the major.

Diagnosis A large brown member of the flavens  HNS  group whose major is distinguished by its square head shape in frontal view, angulate profde of the mesonotal convexity, and rugoreticulate mesosomal dorsum. The minor is very distinctive in the completely rugoreticulate condition of the posterior half of the head, promesonotal dorsum, and mesopleuron.

Similar to quadriceps  HNS  of Colombia but differs in the major by its much shorter propodeal spine, less extensive sculpturing on the head, the rugoreticulum of the mesosoma, which is completely lacking in quadriceps  HNS  , and in color, and in the minor by the mesosomal rugoreticulation, which is absent in the quadriceps  HNS  minor, and also in color. See also the less similar kuna  HNS  , obtusopilosa  HNS  , rectisentis  HNS  , scabriventris  HNS  , and termitobia  HNS  .

measurements (mm) Holotype major: HW 1.14, HL 1.14, SL 0.62, EL 0.14, PW 0.54. Paratype minor: HW 0.54, HL 0.66, SL 60, EL 0.06, PW 0.38.

Color Major: head bicolorous, with head anterior to eyes yellow and remainder of head light brown (the holotype may be a callow); body light brown; tarsi and funiculi yellow; rest of legs light brown.

Minor: body dark brown; tarsi and funiculi dark yellow; rest of appendages medium brown.
