Nothing is known about the biology of Myrmecina bandarensis.

Identification

Okido, Ogata, and Hosoishi (2020) - Similar to Myrmecina maryatiae and species of the macrops complex by its large eye and head shape. Myrmecina bandarensis differs by its sculptured head and long antennal scape.

Description

Worker

Okido, Ogata, and Hosoishi (2020) - TL 2.48-2.60, HL 0.59-0.61, HW 0.60-0.62, CI 101-103, SL 0.51-0.56, SI 85-90, PW 0.37-0.38, ML 0.64-0.69 (3 measured).

Head subrectangular, shorter than broad in full-face view; median portion of occipital margin slightly 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 blunt basal tooth. Dorsal surface of clypeus not concave; median portion of anterior margin slightly projected with a median process; lateral portion simple, lacking sharp ridge in front of antennal insertions. Anterior dorsal surface of labrum with paired denticles, fused with each other at base. Frontal carinae virtually absent, indistinguishable from rugae on dorsum of head. Eyes extremely large and convex, and located at anterior portion near the mid point of head in profile, varying in size with maximum diameter 0.14-0.16 mm and 7-8 ommatidia; malar space as long as diameter of eye in profile; distance between occipital margin and posterior margin of eye 1.5 times as long as diameter of eye. Antennal scape long, extending beyond posterolateral corner of head; antennal flange fully developed.

Dorsal outline of mesosoma slightly convex in profile. Pronotum without denticles; anterior portion not marginate; anterior ventrolateral portion more or less projected; anterior dorsolateral portion rounded. Furrow between pronotum and mesoepisternal projection broad. Eumetanotal spine present but small. Propodeal spine triangular, longer than broad at base, just reaching vertical posteriormost limit of propodeum in profile. Propodeal lobe low. Propodeal spiracle large, situated near base of propodeal spine, distance between posterior margin of spiracle and posterior margin of propodeum longer than diameter of spiracle. Petiole short, as long as high in profile, and slightly longer than broad in dorsal view; dorsal crest located at midlength in profile; subpetiolar process absent. Postpetiole as broad as petiole in dorsal view; dorsal outline flattened in profile; ventral outline slightly projected rectangularly.

Anterior margin of gaster not concave in dorsal view; first gastral sternum simple without median longitudinal ridge.

Head with straight rugae which are thick and longitudinal; ventrolateral portion smooth and shining. Clypeus smooth and shining. Mesosoma with straight rugae which are thick and longitudinal. Forecoxa smooth and shining. Petiole and postpetiole with a few rugae. First gastral segment smooth and shining. Head and mesosoma with relatively sparse and long pilosity on dorsum, hairs of pronotum as long as propodeal spine. Petiole without hairs on ventral surface. Postpetiole with 4 hairs on ventral surface. Body brown to reddish brown, mandibles, antennae, and legs yellowish brown.
