Strumigenys hindenburgi

The only biological information known about this species is the specimen label data from a P. Ward collection: tropical moist forest, sifted litter (leaf mold, rotten wood).

Identification
Bolton (2000) - A member of the hindenburgi complex in the Strumigenys hindenburgi-group. Closely related to Strumigenys cosmostela but always lacking coarse sculpture on the pronotum, hindenburgi is also separated by its longer and more slender hind femora (see above) and very obviously expanded upper scrobe margins.

Distribution based on Regional Taxon Lists
Neotropical Region: Argentina, Brazil, Paraguay.

Castes
Ergatoid queens have replaced winged queens completely (Silva & Brandao 2014)

Nomenclature

 *  hindenburgi. Strumigenys hindenburgi Forel, 1915c: 357 (w.) ARGENTINA. Brown, 1961a: 63 (q.). See also: Bolton, 2000: 520.

Worker
Bolton (2000) - TL 2.5-3.0, HL 0.63-0.70, HW 0.52-0.62, CI 82-88, ML 0.37-0.40, MI 57-61, SL 0.34-0.40, SI 65-70, PW 0.32-0.35, AL 0.63-0.70 (8 measured).

With characters of hindenburgi-complex. Head and promesonotum very densely reticulate-punctate. Walls of punctures on head may be aligned in places and appear as minute irregular rugulae; on pronotum a few feeble rugulae may occur. With head in full-face view upper scrobe margins expanded and lamellate, at maximum about as wide as maximum width of scape. Apicoscrobal hair flagellate. Preocular carina in profile directed obliquely downward toward eye. Disc of postpetiole with feeble rugulose sculpture. Basigastral costulae fine and dense, longer than postpetiole disc. Flagellate hairs on first gastral tergite long fine and abundant, too numerous to count easily; similar but shorter hairs abundant on first sternite.

Type Material
