Specimen Labels

Little is known about the biology of Myrmoteras mjoebergi; a specimen of this ant was collected from a rainforest.


Moffett (1985) - Head smooth, lacking sculpture. Distinguished from Myrmoteras iriodum by its shorter mandibles (MI < 130), four-segmented maxillary palps, low, rounded petiolar node, and greatly reduced pilosity.

  • mjoebergi. Myrmoteras mjoebergi Wheeler, W.M., in Creighton, 1930a: 188, fig. 2; pl. 11, fig. 1 (w.) BORNEO. Combination in M. (Myrmoteras): Moffett, 1985b: 25.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Moffett (1985) - Syntypes (three measured): TL 5.6 to 6.0, HW 1.02 to 1.08, HL 1.12 to 1.18 (CI 91 to 92), ML 1.26 to 1.31 (MI 111 to 112), SL 1.21 to 1.27 (SI 116 to 119), EL 0.66 to 0.71, HFL 1.43 to 1.55 (TWI 17 to 18), WL 1.60 to 1.70 mm. Frontal sulcus absent (slightest trace between antennae in some lights). Palpal segmentation consistently 4,3. Mandibles with 10 to 12 teeth (usually 10) and one to two preapical denticles (usually two); apical pair with larger (most distal) denticle thinner and generally coming to a sharper point than in other species in the binghami group.

Pronotum higher and more rounded than in other species in the subgenus; propodeum also convex, slightly flattened dorsad in one specimen. Metanotal groove not visible as a conspicuously impressed notch in profile. Propodeum evenly and feebly convex in profile. Node of petiole low, rounded; anterior face more precipitous. Ventral margin of petiole feebly convex or feebly concave beneath node.

Head and trunk smooth, lacking punctures or other traces of sculpture outside of poorly defined longitudinal rugae on sides of mesothorax. Hairs short and sparse, rising about 0.10 mm, with 8 to 12 rising above dorsal margin of trunk in profile. Metathoracic tubercle hairs one or none; node of petiole with ca. five to seven hairs. Head and trunk uniform orange red, petiole orange, gaster yellow brown; legs, antennae, and mandibles strongly contrasting orange yellow.

Type Material

Moffett (1985) - Borneo: Mt. Tobangs (top) (Bukit Tabong? [Sarawak]) 1,700 m, 3 worker paratypes. (E. Mjoberg, Museum of Comparative Zoology [examined]).
