Nothing is known about the biology of Holcoponera nigrivitrea.

Identification

A member of the porcata subgroup (in the striatula species group). The closest species to Holcoponera nigrivitrea is Holcoponera brunnea, but its well impressed mesometanotal groove, angulate anterolateral pronotal area and depressed apical and basal mandibular margins permit easy separation. (Lattke 1995)

Description

Worker

Holotype (paratype) measurements: HL 1.10 (1.10); HW 0.86 (0.82); ML 0.86 (0.82); ED 0.14 (0.12); SL 0.82 (0.84); WL 1.40 (1.36) mm; CI 0.79 (0.79); SI 0.95 (1.02); OI 0.16 (0.15). Head elongate; fairly parallel sided in frontal view; posterior margin slightly concave; clypeal lamella widest medianly, giving it a bluntly pointed aspect; eyes moderately protuberant. Mandibles triangular and shallowly costulate; no trace of mesometanotal suture; pronotum anterolaterally convex; declivitous propodeal face longitudinally costulate; metacoxal tooth triangular; node posteriorly inclined, in lateral view with a broadly convex anterior margin and a bluntly pointed apex which slightly overhangs the posterior margin, in dorsal view with longitudinal costulae; subpetiolar process is an anteriorly projecting lobe; anterior face of postpetiole with 3 transverse costulae, costulation longitudinal on dorsal face; postpetiolar sternum with distinct costulation; scape with few standing hairs and moderate amount of decumbent pilosity. Body black; antennae, legs, metapleural gland area, and gastric apex brown. Coxae very dark brown.

Type Material

Holotype worker: Colombia, Valle: Reserva Forestal de Yotoco, 3°50'N 76°25'W, 42 km N E Cali, 1100-1500 m, 6-I-84, W.P. Mackay, leg. No. 7221. Deposited in Instituto de Zoologia Agricola. Paratype: One worker with same locality data as holotype, deposited in Los Angeles County Museum of Natural History.

Etymology

The species name is derived from the Latin adjectives for black, nigra, and for glassy, vitra, and alludes to the black and shining sculpture.
