Nothing is known about the biology of Myrmoteras morowali.
Identification
Moffett (1985) - Distinguished from closely related Myrmoteras wolasi and Myrmoteras toro by the finely granulate sculpture dorsally on head and pronotum; very smooth and shining frontal area; granulate clypeus; presence of transverse rugae across declivity of propodeum, which is smooth only near base; and light yellow color, with the petiole concolorous with trunk and gaster.

Description
Worker
Holotype (HW 0.80) and four paratypes: TL 4.2 to 4.5, HW 0.80 to 0.82, HL 0.83 to 0.85 (CI 96 to 97), ML 1.13 to 1.19 (MI 140 to 144), SL 0.87 to 0.90 (SI 108 to 112), EL 0.49 to 0.50, HFL 0.87 to 0.93 (TWI 22 to 23), WL 1.15 to 1.20 mm. Frontal sulcus a very narrow, well-defined groove. Frontal area very clearly defined. Mandibles with 11 to 12 teeth (usually 11) and two to four preapical denticles (usually three). Smallest apical denticle tiny, closely applied to the larger denticle, which is small and sharp. Mandibles with feeble but conspicuous medial grooves extending longitudinally for most of the length of the shafts (absent in Myrmoteras wolasi).
Trunk very similar to Myrmoteras toro, except propodeum dorsally flattened and with posterior slope of petiole relatively straight, curving only at base and summit. Metanotal groove conspicuously impressed but narrower than in M. toro.
Finely and regularly granulate dorsally on head and clypeus, also granulate (but more feebly) on back of head, including occipital lobe; granules ca. 0.01 mm across. Frontal area smooth and translucent, and thus standing out prominently. Sides of head below eyes longitudinally granulorugose; ventral surface of head smooth. Pronotum granulate, granules formed into broad longitudinal rugae, particularly dorsad; mesonotum densely longitudinally rugose, with traces of granulate sculpture, pleura of mesothorax with similar, but less dense rugae, granulate sculpture absent; propodeum with longitudinal granulate rugae, declivity transversely rugose except near base. Pilosity dense, with 30 to 36 hairs breaking dorsal margin of trunk in profile. Hairs short, rising to 0.06 to 0.08 mm on head and 0.10 mm on trunk and gaster. Two or three hairs at or near each metathoracic tubercle; node of petiole with four to eight hairs. Color exceptionally light, uniform yellow or orange yellow, mandibles somewhat lighter.
Queen
TL 4.5, HW 0.80, HL 0.83 (CI 97), ML 1.13 (MI 137), SL 0.86 (SI 107), EL 0.48, HFL 0.90 (TWI 22), WL 1.21 mm. Dorsum of trunk granulate, with the mesonotum and scutellum longitudinally granulo-rugose; mesepisternum much smoother; propodeum with strong narrow transverse rugae 0.02 to 0.03 mm apart, smooth low on declivity. Uniform yellowish orange.
Type Material
Holotype. Worker deposited in The Natural History Museum from Indonesia: Central Sulawesi: near Morowali, Ranu river area, 27.i.-20.iv.l980, B.M. 1980-280 (M. J. D. Brendell).
Paratypes. One dealate queen and four worker paratypes with same locality data and collection number (BMNH and Museum of Comparative Zoology).
Etymology
Name is a noun in apposition after the type locality.
