Psyche 
[Vol. 90 
scapes very short. Sculpture composed of distinct punctures, fine 
and densely arranged on cephalic dorsum, with smooth to finely 
shagreened interspaces. 
Worker, holotype and six paratypes from type nest series: TL 
6.0-6.3, HL 1.27-1.31, HW 0.98-1.04 (Cl 76-82), ML 0.76-0.78 
(MI 75-83), SL 0.74-0.77 (SI 75-80), EL 0.22-0.25, WL 2.01-2.09 
mm. 
Head with gently convex subparallel sides, straight to feebly con- 
vex occipital border, and broadly rounded posterior angles. Grea- 
test head width slightly behind midlength. Eyes oval, only feebly 
convex, their greatest diameter greather than maximum width of 
scape; about 12-15 fine facets in rows across the short axis; eye 
separated from anterior corner of head by about 2/3 its own length 
or slightly more. Frontal sulcus extends slightly beyond midlength 
of head. Median clypeal process obsolete, represented only by a 
weak convexity between the frontal lobes with two or three minute 
piligerous tubercles. Form of mandibles shown in Figs. 2, 3. Scapes 
reaching roughly to about 3/4 the distance between their insertions 
and the occipital border; segment I of funiculus distinctly longer 
than II; II through X increasing rather uniformly in size, so that no 
club is formed. 
Trunk as seen from side forming gentle, subequal promesonotal 
and propodeal convexities, separated by the impressed metanotal 
groove. Petiolar node slightly higher than long seen from the side 
(without subpetiolar process) and very slightly longer than broad 
seen from above. Postpetiolar segment seen from above about 4/5 
as long as broad, slightly shorter than the succeeding segment. 
Dorsum of head densely sown with fine, uneven-sized punctures, 
close together, but interspaces mostly smooth and shining; region 
posteromesad of compound eyes with densest punctation. Sides and 
underside of head smooth and shining and with scattered coarse 
punctures. Mandibles, gastric apex, scapes and legs smooth and 
shining. 
Trunk, petiole, and first two gastric segments with numerous 
coarse, mostly elongate piligerous punctures. Between punctures the 
integument is mostly smooth to shagreened on the dorsum, becom- 
ing striolate and subopaque on sides and rear of trunk and petiolar 
node, and to some extent on mesonotum and propodeal dorsum. 
Pilosity of fine, tapered, erect hairs, moderate in length and gen- 
erally distributed. Head with abundant, mesally directed decumbent
