Nothing is known about the biology of Monomorium schultzei.

Identification

Bolton (1987) - A member of the M. schultzei complex in the M. monomorium species group. M. schultzei is closest related to Monomorium excensurae and Monomorium bevisi. The last named is a larger and more densely hairy species, and it is also distinctly darker in colour. Differences between schultzei and excensurae are discussed under the latter name.

Description

Worker

Bolton (1987) - TL 2.0-2.2, HL 0.54-0.58, HW 0.42-0.46, CI 77-80, SL 0.42-0.46, SI 97-102, PW 0.25-0.30, AL 0.54-0.60 (10 measured).

Clypeal carinae sharply developed, close together and subparallel, at most only weakly divergent anteriorly. Area of clypeus between the carinae concave and the anterior c1ypeal margin between the apices of the carinae concave. Prominent median section of clypeus narrow, its anterior and lateral margins. separated by an angle which may be sharp, but without projecting denticles. Eyes relatively large, maximum diameter 0.24-0.27 x HW and with 7-8 ommatidia in the longest row. In full-face view the posterior margins of the eyes at the midlength of the sides of the head. Antennal scapes, when laid straight back from their insertions, just reaching the occipital margin. Sides of head behind eyes shallowly convex, the occipital margin broadly and shallowly concave. Major features of head very similar to that of excensurae, Fig. 61. Promesonotum in profile convex, its highest point in front of the promesonotal midlength and on a much higher level than the propodeum. Mesonotum sloping posteriorly and its outline almost flat. Metanotal groove very narrow and only feebly impressed, traversed by short and inconspicuous cross-ribs. Propodeal dorsum sloping posteriorly, the spiracle minute and pinhole-like. Petiole in profile with an elongate narrow peduncle which is subtended by a small lobiform anteroventral process. Node of petiole narrow and subconical, narrowly rounded above. Postpetiole smaller, lower and more broadly rounded than petiole. In general the shape of the petiole and postpetiole is similar to that seen in excensurae (Fig. 75) but the subpetiolar process is smaller and the node slightly narrower. Viewed from above the dorsal surfaces of both nodes are distinctly broader than long. All dorsal surfaces of head and body with standing hairs, the promesonotum with 5-6 pairs. Sculpture absent except for scattered minute hair-pits, the feeble metanotal cross-ribs and some meso- and metapleural vestiges. Colour predominantly yellow but the cephalic dorsum and gastral tergites duller and with a pale brownish yellow tint in some.
