  • diligens. Pheidole diligens Santschi, 1923d: 50 (s.w.) BRAZIL. [Junior secondary homonym of diligens Smith, above.] Replacement name: blumenauensis Kempf, 1964e: 64.
  • blumenauensis. Pheidole blumenauensis Kempf, 1964e: 64. Replacement name for Pheidole diligens Santschi, 1923d: 50. [Junior secondary homonym of Atta diligens Smith, F. 1858b: 168.] See also: Wilson, 2003: 171.

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


From Wilson (2003): A small, reddish brown member of the diligens group, whose major has a moderately prominent mesonotal convexity, which is part of a bilobed promesonotal outline as seen in dorsal-oblique view; short, nearly equilaterally triangular propodeal spines; overall mostly smooth and shiny body surface with sculpturing on the head composed exclusively of longitudinal carinulae confined to the anterior half; and abundant, medium-length, erect pilosity.

Close to Pheidole rochai and Pheidole vafra, but differing variously in head shape, eye size, sculpturing, and color. See also the less similar Pheidole lemur, Pheidole perryorum, Pheidole pubiventris, Pheidole seeldrayersi and Pheidole variegata (= Pheidole pubiventris), as illustrated.

Minor: virtually identical to that of Pheidole rochai, as illustrated (q.v.).

MEASUREMENTS (mm) Lectotype major: HW 0.96, HL 1.00, SL 0.78, EL 0.20, PW 0.54. Paralectotype minor: HW 0.52, HL 0.64, SL 0.78, EL 0.16, PW 0.38.

COLOR Major: concolorous reddish brown.

Minor: body light brown, appendages brownish yellow.
