Description
Worker major.--Length 8-9 mm. Mandibles, front of head, scapes and gaster black; occiput, thorax and node brown, funiculi and all legs yellow. Mandibles finely striate near apex, shining at base, remainder of body very finely and densely reticulate with scattered small shallow punctures. Hair yellow, long and erect, rather scattered on thorax and gaster, very short and sub-erect on antennae and legs. Pubescence very fine and adpressed throughout. Head a fraction broader than long, occipital border feebly, sides strongly convex, angles rounded. Mandibles with five or six large sharp teeth. Clypeus flat convex above, strongly projecting in front, anterior border straight, fully half the width of clypeus, angles sharp. Frontal area triangular, small and shallow. Frontal ridges one-fourth longer than broad behind, a faint longitudinal groove in middle. Scapes extend beyond occipital border by almost one-fourth their length, first and third segments of funiculus equal in length, one-sixth longer than second, apical very slightly longer than preceding segment. Eyes large, rather flatly convex. Thorax almost twice as long as broad, promesonotal suture sharply and deeply impressed, meso-epinotal suture feebly impressed. Pronotum one and three-quarter times broader than long, strongly convex in front and on side. Mesonotum very slightly broader than long, convex in all directions. Epinotum slightly longer than broad, convex transversely; in profile evenly longitudinally, sutures sharply defined, epinotal declivity barely as long as dorsum into which it is broadly rounded. Node twice as broad as long, oval, sharply pointed above; in profile barely twice as high as long, anterior and posterior faces convex, sharp pointed on top. Gaster one-fifth longer than broad. First segment three times broader than long, strongly convex in front. Legs long and stout.
Worker media.-Length 6.5-7 mm. Mandibles and gaster black, head and scapes brown, thorax, funiculi and node reddish yellow, legs yellow. Sculpture and pilosity as in worker major. Head as long as broad, occipital border and sides convex, angles broadly rounded. Mandibles with six large sharp teeth, decreasing in size towards base. Clypeus convex above, projecting and sharply convex in front, bluntly pointed. Frontal area large and shallow, triangular. Scapes extend beyond occipital border by one-third their length, funiculus as in major worker. Eyes more convex, placed far back, almost their diameter from occipital border. Thorax twice as long as broad, strongly constricted at meso-epinotal junction; in profile like major worker, but epinotal declivity shorter. Node and gaster similar. Legs more slender.
Worker minor. Length 4.5-5 mm. Color, sculpture and pilosity as in worker media. Head one-sixth longer than broad, strongly convex behind eyes, feebly convex in front. Scapes extend beyond occipital border by almost half their length. Thorax fully twice as long as broad; in profile pronotum feebly convex. Mesonotum high and convex in front, forming a straight edge with epinotum behind, declivity short, strongly rounded into dorsum. Node one-forth broader than long, oval, top edge sharp, transversely convex; in profile higher than long, bluntly point above. Gaster and legs as in worker media.
Habitat.-Reevesby Island. A small nest was found in a dead limb of the "Native juniper" or "boobialla" (Myoporum insulare R. Br.).
