The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • vafella. Pheidole vafella Wheeler, W.M. 1925a: 15 (s.w.) BOLIVIA. See also: Wilson, 2003: 243.

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


From Wilson (2003): The major and minor are from different localities, as noted in the figure caption. One or more majors from the type locality may be in the Royal Museum of Stockholm and were not seen by me, hence the association of the two castes I have made here is based on Wheeler’s judgment and what does appear to correspond between them in habitus, sculpturing, and pilosity.

P. vafella is somewhat similar to Pheidole crozieri and Pheidole williamsi, differing as follows.

Major: scapes just reach occipital lobes, head heart-shaped in full-face view; propodeal spines reduced to a right angle in side view; propodeal dorsum transversely carinulate; densely covered with short, erect to suberect hairs.

Minor: propodeal spine reduced to denticle; petiolar node low.

MEASUREMENTS (mm) Syntype major (Mojo, Bolivia): HW 1.04, HL 1.08, SL 0.80, EL 0.16, PW 0.56. Syntype minor (Yanalomas, Bolivia): HW 0.56, HL 0.68, SL 0.84, EL 0.14, PW 0.40.

COLOR Major: concolorous dark yellow.

Minor: concolorous brownish yellow.
