A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 131 
Apical half of mandibles coarsely striate, basal half finely reticulate. Head longi- 
tudinally striate, very finely and densely reticulate between the striae. Pronotum 
longitudinally arched striate-rugose, the striae widely separated, the spaces densely 
reticulate. Mesonotum more finely and closely striate longitudinally, reticulate 
between the striae. Epinotum coarsely striate-rugose and reticulate longitudinally 
on top; declivity transversely rugose. Node irregularly, almost circularly rugose. 
Postpetiole and gaster very finely and densely reticulate. 
Hair yellow, short and erect, long and more abundant on mandibles and apical 
segments of gaster, short and suberect on legs. None on antennae. Pubescence 
yellowish, very fine and adpressed, abundant throughout; on dorsum of first 
segment of gaster it is more abundant but not hiding the sculpture, golden yellow 
on the three apical segments, long and abundant, hiding the sculpture. 
Head very slightly broader than long, occipital border feebly concave, angles 
broadly rounded. Mandibles as long as head, external border feebly concave; 
apical half of inner border furnished with three large, sharp, erect teeth and five 
smaller; teeth on basal half short, broad and directed backward. Clypeus deeply 
excised in front. Scapes extend beyond occipital border by barely their thickness; 
second segment of funiculus one-sixth longer than first, third equal to first, 
remainder subequal. Thorax twice as long as broad, pronotum twice as broad as 
long, strongly convex in all directions. Mesonotum one-fourth broader than long, 
sides strongly convex, feebly convex in front and behind. Epinotum one-fifth 
longer than broad, flattened laterally above, sides and front feebly convex; in 
profile strongly convex from apex of pronotum to apex of epinotal declivity, sutures 
sharply impressed, mesonotum higher than pronotum and epinotum. Node one- 
fifth broader than long, convex in all directions; in profile anterior and posterior 
faces straight, vertical, dorsum feebly convex, borders rounded. Ventral spine 
erect, short and sharp. Postpetiole fully one-third broader than long, strongly 
convex in all directions, constriction wide but shallow. First segment of gaster 
slightly broader than long, broadest behind, sides strongly convex. Legs robust. 
Female. Length 14-15 mm. 
Colour, sculpture and pilosity similar to that of the worker. Larger and more 
robust. Wings hyaline with a yellow tinge. 
Male. Length 12:5 mm. (according to Emery). 
I have not seen the male, but for the sake of completeness give a translation of 
Emery’s description as follows: 
“The male differs similarly from that of M. pilosula by the broader petiole and 
by the colour of the mandibles, antennae and legs. Length 124 mm.” 
Habitat —South Australia: Tepper (? type locality) ; Wilpena Pound (H. Hale) ; 
Port Lincoln (J. Clark). 
Western Australia: Mundaring (J. Clark) ; Emu Rock (H. Reynolds). 
Victoria: Lake Hattah (J. E. Dixon). 
Federal Capital Territory: Canberra (G. F. Hill). 
The male and female were described from an unknown locality 
in South Australia. The worker, therefore, has been deseribed 
from examples collected at Port Lincoln. In his descriptions of 
the male and female Emery compared them with M. pilosula, but 
they have no connection with that species; beyond size and colour 
there is little resemblance. This species is widely distributed in 
the warm mallee districts and it is surprising to find it at Canberra.
