Nomenclature

 *  brevicornis. Typhlatta brevicornis Mayr, 1879: 669 (w.) INDIA. [Typhlatta brevicornis Smith, F. 1873: ix. Nomen nudum, attributed to Mayr.] Imai, Brown, et al. 1984: 8 (k.). Combination in Aenictus: Dalla Torre, 1893: 7. See also: Wilson, 1964a: 451.

Worker
Wilson (1964) - Lectotype (herein designated from a syntype in the collection of the Naturhistorisches Museum, Vienna). HW 0.53 mm, HL 0.60 mm, SL 0.35 mm, Sl 66. Antenna 10-segmented. Mandible very narrow, bearing 3 large teeth; in closure, leaving a gap between its posterior border and the anterior clypeal border. Anterior clypeal border flat in the center, entire, armed with 7 well-developed teeth. Parafrontal ridge absent. Occiput convex, lacking collar. Propodeal faces seen in side view straight, approaching one another at an angle of about 100°; but their junction evenly rounded. Subpetiolar process a flat, forward-directed lobe surmounted by a subtriangular flange whose apex is posteriorly directed. Pilosity extremely abundant overall, more than in any other Indo-Australian member of the genus; length of the longest pronotal hairs about 0.20 mm.

Head shining. Mesopleuron, metapleuron, and propodeum microreticulate, opaque; remainder shining. Pedicel microreticulate overall; dorsa feebly shining, remainder opaque. Brownish yellow; head and alitrunk a shade darker than the rest.

Paratype: HW 0.51 mm, HL 0.60 mm, SL 0.35 mm, Sl 69. Very similar to the lectotype, but differing greatly in the shape of the subpetiolar process: this structure is much smaller, and the ventral flange is directed anteriorly (fig. 53). This difference between the 2 syntypes examined induced me to designate a lectotype, on the chance that 2 species are represented in the original Mayr series.
