Anochetus princeps

[4] Anochetus princeps I have already dealt with the synonymy of A. princeps (Brown, 1964), which is widespread in forested parts of soiutheastern Asia and the Greater Sunda Islands. Much of the material in MCZ comes from North Borneo: Tutu River; Mt. Poi, Sarawak, 5000 ft.; Mt Penrissen, 4000 ft.; Tobang; all collected by E. Mjöberg. I have also reviewed specimens from the Andaman Is.: Peel Islands, B. Osmaston; and Mt. Makiling, Lagunas Prov., Luzon (F. X. Williams, "low alt."), and new series from SE Celebes: Silea, 28 km W of Kendari, rotten wood in wet forest, W. L. Brown; 1-2 km E of Wolasi, 42 km S of Kendari, rotten wood in wet forest (Brown). At Silea, A. princeps was taken within 100 m of A. gladiator nests, aiso made in rotten wood on the forest floor. Male: With the sample from Mt. Penrissen, North Borneo (MCZ) there is a male mounted on the same pin with a worker, and almost certainly of the same species. TL 5.6, HL 1.00, HW including eyes 1.13, WL 2.20. Ocelli large (greatest diameter 0.14 mm); compound eyes large, very convex, taking up most of sides of head, but separated from lateral ocellus by a gap 0.20 mm long. Mandibles very small, subtriangular, their dorsal surfaces each bearing a conspicuous whitish, subcircular basin perhaps an evaporation basin for pheromones. Maxillary palpi apparently 4-merous, 2 basal segments wide. Sides of trunk strongly convex. Petiolar node forming a blunt cone, much like that of worker, but back-tilted. Terminaba rather ordinary. Pygidium with entire, narrowly-rounded free margin. Cerei prominent. Hypopygium tapered-linguiform, with convex ventral surface. Parameres rather narrow, tapered toward narrowly rounded apices, obtusely bent mesad and ventrad beyond midlength, with convex outer surfaces. Digitus and cuspis of volsella subequal in length; aedeagus without prominent lateral expansions or processes. Body generally covered with abundant, mostly decumbent, brown, short hair (or long pubescence), through which can be seen the moderately shining, densely punctulate integument. Color warm tan; vertex and scutum partly darker brown; lower meso- and metapleura, mouthparts, legs and terminalia pale, dull, yellowish. Wings (forewing L 4.8 mm) pale brownish, with «full» venation of tribe Ponerini. Hind wing with well-developed anal lobe and 10 submedian hamuli.Published as part of Brown, WL Jr.,, 1978, Contributions toward a reclassification of the Formicidae. Part VI.
