Nothing is known about the biology of Holcoponera gentryi.
Identification
A member of the porcata subgroup (in the striatula species group). Quite easy to separate from all others considering just the presence of a metanotal groove and the mostly smooth and shining gaster. (Lattke 1995)

Description
Worker
Holotype measurements: HL 1.22; ML 0.32; HW 0.92; ED 0.22; SL 1.04; WL 1.64 mm; CI 0.75; SI 1.13; OI 0.24.
Head in frontal view elongate, anterior clypeal margin convex, posterior margin concave, eyes relatively flat, finely costulate throughout, though diverging at vertex, with a band of three transverse costulae next to the vertexal carinae; mandibles triangular, frontal surface rugulose. Scapes mostly smooth and shining except for sparse punctulae.
Pronotal dorsum with whorled costulate almost enclosing 3 brief longitudinal costuiae, rest of mesosomal dorsum with longitudinal costulae, metanotal groove deeper than pronotal suture. In lateral view the mesosoma has a convex pronotal profile that becomes an inclined and more or less straight slope that bends sharply at the propodeal declivity, which has a broadly concave profile. Node in lateral view tilted backwards, with oblique to longitudinal rugulae laterally and transverse costulae on the anterior and posterior faces, ventral process subquadrate, with anterior corner projecting more than posterior corner. Gastric tergite I mostly smooth and shining except for anterior face which has a small area of transverse costulae and the sternite with transverse striae; the rest of the gaster is smooth and shining. Color black.
Type Material
Holotype worker. Colombia, Valle, 2250 m, Insp. Pance, Reserva Natural Hato Viejo, J. B. Hillaire, leg. Deposited in Instituto de Zoologia Agricola.
Etymology
Named in honor of the late botanist Alwyn Gentry, he died in the line of duty in the Andes of Ecuador.
