Smicromyrme athalia Pagden 1949: 219, ♂, ♀, holotype ♂.

Diagnosis. FEMALE. This species has the vertex with a patch of silvery setae; the scape and legs largely reddened; the mesonotum with anterolateral patches of dense white setae, the T2 disc with three horizontally aligned setal spots, the middle spot more yellow-tinted or obliterated; the apical margin of T2 with black setae only; the T2 felt line with silver to golden setae; T4 with lateral patches of silvery setae; and the pygidium elongate ovate with moderately-spaced striae and the apex smooth. Body length 4–6 mm. MALE. See Lelej (1996a).

Remarks. In the description by Pagden (1949) this species is mentioned as having anterolateral patches of white setae on the mesonotum. These patches vary in intensity (Figs 77, 78) but seem to be present in all the Thai specimens we observed. Differentiating them from M. bicristata (Chen, 1957), then, is now difficult, as the presence of these spots is the primary diagnostic feature of M. bicristata in the only key to species (Lelej 1996a). According to the description (Chen 1957), M. bicristata has the lateral and medial spots on the disc of T2 concolorous pale golden, while all the M. athalia specimens have the lateral spots silvery and the medial spot golden (Fig. 77) or obliterated (Fig. 78). Molecular studies or comparisons of the ♂ s will be needed to determine whether M. athalia and M. bicristata truly are distinct species.
Some individuals of M. athalia and M. puttasoki, sp. nov., tend to have the medial spot of T2 obliterated and replaced by black setae. This makes them the only Smicromyrmini specimens to have T2 marked with two lateral setal spots, the diagnostic feature for Trogaspidiini. To our knowledge, none of the Trogaspidiini have anterolateral white mesonotal spots like these two Mickelomyrme species. Also, the T2 spots are located at the extreme lateral margins of T2, while most Trogaspidiini have the spots more centrally oriented.
