138 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
tugose behind, the rugae appear more as elongate punctures. Gaster microscopically 
punctate. 
Hair yellow, erect, abundant throughout, very long on mandibles and gaster, 
short and suberect on antennae, a little longer on legs. Pubescence very fine and 
whitish, very close lying, longer and more abundant on postpetiole and sides of 
gaster forming a thin covering at middle of posterior border of postpetiole, on the 
gaster the pubescence is bright golden red, long, dense and adpressed, hiding the 
sculpture. 
Head slightly broader than long, sides convex, occipital border concave, angles 
rounded. Mandibles fully their width at base, longer than head, parallel, external 
border convex, inner border furnished with four large, sharp, erect teeth at apex, 
behind these the teeth becoming shorter and broader to base, where they are 
obsolete. Scapes extend to occipital border; first and third segments of funiculus 
equal in length, second one and one-half times longer, Thorax fully twice as long 
as broad ; pronotum almost twice as broad as long, sides and front strongly convex, 
dorsum flat; mesonotum as long as pronotum, about one-fourth broader than long, 
strongly convex in all directions, excision deep and narrow; epinotum one and 
one-half times longer than broad, bluntly rounded in front, dorsum convex; in 
profile pronotum evenly convex from apex to base, mesonotum slightly higher 
than pronotum and epinotum, highest in front, evenly convex from apex to’ base, 
epinotum twice as long as declivity into which it is rounded. Node very slightly 
broader than long, broadest behind middle, one-fourth broader behind than in 
front, anterior and posterior borders straight, sides convex; in profile slightly 
higher than long, anterior face vertical, feebly convex, posterior face straight, both 
faces rounded into the convex dorsum, ventral spine triangular, sharp pointed. 
Postpetiole one and one-half times broader than long, broadest at posterior third, 
constriction deep and wide. First segment of gaster broader than long. Legs robust. 
Female. Length 15-15-5 mm. 
Colour and pilosity as on the worker, sculpture similar but much coarser. 
Head one-eighth broader than long, occipital border and sides feebly convex, 
angles broadly rounded. Mandibles slightly longer than head, external and inner 
borders feebly convex, inner border furnished with nine large, broad, sharp, erect 
teeth in front of middle; behind these the teeth are smaller and directed forward 
(backward in worker). Scapes barely reach occipital border. Thorax fully twice 
as long as broad; pronotum three times broader than long; mesonotum broader 
than long, broadly convex in front, mayrian furrows feebly indicated, parapsidal 
furrows weakly impressed; scutellum almost twice as broad as long, strongly 
convex; epinotum one and one-half times broader than long. Node one-fourth 
broader than long, broadest behind middle, anterior and posterior borders straight, 
sides strongly convex; in profile higher than long, anterior and posterior faces 
straight, vertical, rounded into the feebly convex dorsum, ventral spine triangular, 
short and sharp. Postpetiole one-third broader than long, strongly convex. First 
segment of gaster slightly broader than long, slightly broader behind than in front. 
Legs robust. Wings hyaline. 
Male, Length 11-5-12-5 mm. 
Colour as on the worker. Hair and pubescence longer and more abundant 
throughout. Sculpture more punctate-rugose, the bottom of punctures densely and 
finely punctate. 
Head as long as broad, occipital border short, straight or feebly convex, sides 
strongly convex. Mandibles short, triangular, the angle on inner border forming 
a sharp tooth. Scape twice as long as first segment of funiculus, second segment 
three times longer than scape. Thorax twice as long as broad. Pronotum very
