Neotropical Region: Colombia.

Nomenclature

 *  sculpturata. Leptanilloides sculpturata Brandão, Diniz, Agosti & Delabie, 1999: 30, figs. 7, 8, 17, 24 (w.) COLOMBIA.

Worker
(MZUSP paratype) (in mm): HL 0.29, HW 0.17, SL 0.09, WL 0.48, CI 58, SI 48.

The combination of the postpetiole as long as the petiole, the coarse foveolate sculpture and the minute mandibular teeth distinguishes this species from all other Leptanilloides. Other relevant characters include: head with parallel sides in full-face view, head sculpture coarse with up to 25 deep foveolae covering a straight transverse line at head midlength; inner margins of the frontal carinae do not touch; flange over the metapleural gland opening pointed posteriorly; petiole, in lateral view, as long as postpetiole; postpetiole nearly as high than the fourth abdominal segment.

Type Material
Holotype worker deposited at NMNH. Colombia: Venecia (near Medellin) # 56–6029, v.1956, Stanley E. Flanders leg. ‘associated with R. fuhrmanni on healthy coffee trees’. Three paratype workers (same series as holotype), deposited one each at, and MZUSP.

Etymology
Sculpturata, a noun in apposition, meaning carved in Latin, referring to the conspicuous deep foveolae that almost cover the head of this species.
