Nothing is known about the biology of Myrmecina celebensis.
Identification
Okido, Ogata, and Hosoishi (2020) - Myrmecina celebensis can be distinguished from other Myrmecina species in southeast asia that are not in a Myrmecina complex by its anterior clypeal margin without processes and a propodeal spine longer than broad at base.

Description
Worker
Holotype. TL 2.18, HL 0.53, HW 0.48, CI 91, SL 0.42, SI 87, PW 0.33, ML 0.56. Paratype. TL 2.31, HL 0.54, HW 0.50, CI 93, SL 0.40, SI 81, PW 0.34, ML 0.59 (1 measured).
Head subrectangular, longer than broad in full-face view; median portion of occipital margin concave; occipital corners rounded, not projected posteriorly. Masticatory margin of mandible bent at midlength (third small tooth or sixth tooth); apical tooth strong, third tooth robust, followed by 5 small teeth and a basal tooth. Dorsal surface of clypeus not concave; median portion of anterior margin feebly projected without a median process; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with paired small denticles, close to each other. Frontal carinae virtually absent, indistinguishable from rugae on dorsum of head. Eyes small circularly and moderately convex, varying in size with maximum diameter 0.05-0.06 mm and 6-9 ommatidia; malar space twice as long as diameter of eye or longer in profile; distance between occipital margin and posterior margin of eye four times as long as diameter of eye or longer. Antennal scape short, not reaching posterolateral corner of head; antennal flange weakly developed.
Dorsal outline of mesosoma more or less flattened in profile. Pronotum without denticles; anterior portion marginate; anterior ventrolateral portion not angulate. Furrow between pronotum and mesoepisternal projection relatively broad. Eumetanotal spine present. Propodeal spine triangular, longer than broad at base, extending over vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle large, situated near base of propodeal spine, apart from margin by its diameter. Petiole short, slightly longer than high in profile, longer than broad in dorsal view; dorsal crest located at midlength in profile; subpetiolar process variously developed from weakly raised median longitudinal ridge to distinct projection. Postpetiole broader than petiole, 1.5 times as broad as its length except for helcium in dorsal view; anterolateral portion rounded; dorsal outline flattened in profile; ventral outline projected rectangularly with two tops.
Anterior margin of gaster not concave.
Head with thin and weakly waved rugae; ventrolateral portion with longitudinal or oblique rugae weakly. Clypeus smooth and shining. Mesosoma with thin and longitudinal rugae. Forecoxa smooth and shining. Petiole and postpetiole with longitudinal rugae. First gastral tergum punctured distinctly dorsally. First gastral sternum rugulose at anterior and lateral portion. Head with dense and short pilosity on dorsum. Mesosoma with dense and short pilosity on dorsum, hairs of pronotum shorter than propodeal spine. Petiole and postpetiole without hairs on ventral surface. Head and mesosoma black to dark reddish brown, petiole and postpetiole reddish brown, mandibles, antennae and legs yellowish brown.
