  • laticrista. Pheidole (Elasmopheidole) laticrista Santschi, 1916e: 375, 2 figs. (s.w.q.) ARGENTINA. See also: Wilson, 2003: 134.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


From Wilson (2003): Major: frontal lobes greatly expanded anteriorly, so that their edges project beyond the lateral head margins in full-face view, and their flat anterior margins just reach the anterior clypeal border; in side view the frontal lobes project downward over the clypeus like thin horns; pronotum greatly enlarged, in dorsal-oblique view 4X higher than the mesonotal convexity, and seen fromabove more than 2X as wide as the mesonotum; head bicolored (see color below).

Minor: nearly identical to minor of Pheidole cavifrons (q.v.) except for large eye, as illustrated.

MEASUREMENTS (mm) Lectotype major: HW 0.94, HL 1.28, SL 0.22, EL 0.12, PW 0.66. Paralectotype minor: HW 0.50, HL 0.56, SL 0.38, EL 0.08, PW 0.34.

COLOR Major: body medium yellow except for anterior dorsal surface of head, which is medium brown.

Minor: concolorous yellow.
