Arimoto (2017) - A member of the Leptogenys modiglianii species group. In full-face view, head distinctly longer than wide (CI: 77–78). Mandible distinctly curved throughout. Clypeus without lateral lobe; apex of median extension strongly projecting. In profile, petiole higher than long (LPI: 115–117), highest just anterior to posterodorsal angle; anterior and dorsal faces of node forming continuous curve; dorsal face distinctly sloping anteriad. Gastral segment II extensively covered with scalloped depressions. Body covered with understory layer of short, dense and recumbent pubescence.

In full face view, head distinctly longer than wide. Mandible distinctly curved throughout, with subapical tooth near apical tooth. Eye prominent, measuring one-fourth to one-third of head lateral margin length. Antennal scape longer than width of head, surpassing posterior margin of head by less than one-fifth of its length; antennomere III ca. 2.2 times as long as wide. Clypeus without lateral lobe; median extension moderately long, with apex strongly projecting. In dorsal view, pronotum longer than wide. Metanotal groove distinctly impressed. In profile, propodeal dorsum broadly convex. Petiole in profile higher than long, with fan-shaped node, highest just anterior to posterodorsal angle of node; anterior and dorsal faces of node forming continuous curve; dorsal face distinctly sloping anteriad; posterior face almost straight.
Head weakly areolate-rugose, longitudinally striate anteriorly; vertex weakly and transversally striate. Mandible longitudinally striate. Prosternum weakly rugose. Gastral segments I–II extensively covered with scalloped depressions that are irregular in size and close to each other; generally depressions on segment I larger than those on segment II.
Body black-gray; clypeus, mandible, antenna, legs, and ventral half of petiole dark-red. Body covered with understory layer of short, dense and recumbent pubescence. Scalloped depressions on gastral segments I–II bearing hairs.

Holotype. Worker (FI93-34), Sitiung, Dharmasraya, West Sumatra, Indonesia, I 1993, Fuminori Itô leg. Kagawa University Collection. Paratype. 2 workers, 1 queen, same colony as the holotype [1 worker: BLKU; 1 worker, 1 queen: SKY Collection].
From the Latin curvus, meaning curved, referring to the curved mandible.
