Specimen Label

Nothing is known about the biology of Holcoponera extra.

Identification

This species has a fairly pointed petiolar node apex, but it doesn’t approach the extremely pointed condition of Holcoponera acuta. The node is more robust and subquadrate (lateral view) than in other species and is reminiscent of the condition in Gnamptogenys tortuolosa. This species could be closely related to Holcoponera striatula on account of the node shape (erect) and the lacking anterior peduncle. (Lattke 1995)

Description

Worker

Holotype (Paratypes) measurements: HL 1.20 (1.10-1.12); HW 1.00 (0.94-l.00); ML 0.34 (0.30-0.34); ED 0.16 (0.14-0.18); SL 1.26 (l.00-1.20); WL l.68 (1.44-1.50) mm; CI 0.83 (0.85-0.98); SI 1.26 (1.06-1.20); IO 0.16 (0.15-0.19) n = 4.

With head in frontal view: vertexal margin straight, laterally convex with eyes slightly behind midlength, and anterior clypeal margin convex; mandibles triangular with dorsal striae; scapes relatively thick in appearance and surpassing vertexal margin; vertex with 2-3 transverse costulae; anterior pronotal face with 5-7 transverse costulae, dorsally with anteriorly arching costulae; costulae on mesonotal concentric or longitudinal; costulate on metanotum and dorsal propodeal face transverse to longitudinal, sometimes arched; declivitous propodeal face with longitudinal costulae that diverge posteriorly, basally with 2-3 transverse costulae.

Petiolar node in lateral view subquadrate, with broad anterodorsal convexity and sharp posterior drop with overhanging apex; subpetiolar apex is an anteriorly projecting lobe; anterior postpetiolar face with transverse costulae that arch back and become longitudinal posteriorly; rest of dorsal gastric costulae longitudinal, divergent on posterior postpetiolar sternum; ventral stridulitrum present on fourth abdominal segment. Scapes with abdundant decumbent pilosity and no suberect or subdecumbent hairs; decumbent pilosity also present on coxae and legs, with no standing hairs; sparse suberect hairs on rest of body. Body dark brown, legs and antennae slightly lighter.
