Known only from the holotype worker.

Identification

Moffett (1985) - Distinguished from Myrmoteras morowali and Myrmoteras toro by the presence of distinct granulate sculpture on both the clypeus and frontal area (head and pronotum otherwise conspicuously rugose); declivity of propodeum entirely smooth; and color darker, with petiole strikingly lighter in color than trunk or gaster. Also distinguished from M. toro by its smaller size and dorsally flattened propodeum.

Description

Worker

Holotype: TL 4.5, HW 0.88, HL 0.88 (CI 100), ML 1.23 (MI 141), SL 0.96 (SI 109), EL 0.55, HFL 0.98 (TWI 21), WL 1.20. Frontal sulcus a narrow groove, and, like orbital grooves, somewhat wider and more conspicuous than in M. toro. Frontal area clearly defined. Both mandibles with 12 teeth and two denticles. Apical denticles both tiny, with little difference in size as in Myrmoteras toro. Mandibles dorsally without any trace of the feeble medial grooves found in Myrmoteras morowali.

Shape and conformation of trunk and petiole exactly as described for M. morowali, but with node of petiole narrower.

Sculpture on head similar to M. toro, but with rugae wider, 0.03 mm across; rugae longitudinal but diverging somewhat towards occiput. Clypeus and frontal area evenly granulate throughout, not rugose; granules ca. 0.01 mm wide. Back of head smooth except for a few rugae directly behind ocelli; feebly rugulose on occipital lobe as in M. toro. Fine longitudinal rugae on sides below eyes; smooth beneath head. Pronotum similar to M. toro, with rugae like those on head but more sinuous, mostly transverse caudad and mostly longitudinal farther back and on sides; mesothorax and propodeum rugose as described for M. toro, but with declivity entirely smooth. Pilosity very dense, as described for M. toro. Head and trunk orange red, petiole (as well as legs and antennae) contrasting yellowish orange, tarsi and mandibles orange yellow.

Type Material

Holotype. Worker deposited in Museum of Comparative Zoology from Indonesia: S.E. Sulawesi: rainforest 1-2 km east of Wolasi, 42 km south of Kendari, ca. 350 m, 13-14 July 1972 (W. L. Brown).

Etymology

The specific name is a noun in apposition after the type locality.
