Head longer than wide (CI 93 - 96); posterior
head margin weakly concave. Anterior clypeal margin usually entire and
convex, sometimes with very small median notch only visible under
higher magnifications. Frontal carinae strongly developed, approaching
or ending at posterior head margin. Antennal scrobes well developed,
moderately shallow, and with clearly defined margins all around.
Antennal scapes relatively short, not reaching posterior head margin
(SI 73 - 77). Eyes large (OI 27 - 31). Mesosomal outline in profile
weakly convex, moderately marginate from lateral to dorsal mesosoma;
promesonotal suture and metanotal groove absent; mesosoma
comparatively stout and high (LMI 41 - 44). Propodeal spines usually
long to very long (PSLI 30 - 38), elongate-triangular to spinose, and
acute, rarely spines reduced, short, elongate-triangular, and acute
(PSLI 20 - 21); propodeal lobes short, triangular to
elongate-triangular, and acute. Petiolar node in profile rectangular
nodiform, approximately as high as long to weakly higher than long
(LPeI 89 - 100), anterior and posterior faces approximately parallel,
anterodorsal and posterodorsal margins situated at about the same
height, anterodorsal and posterodorsal angles well- developed and
rectangular, petiolar dorsum flat; node in dorsal view around 1.1 to
1.2 times longer than wide (DPeI 81 - 89). Postpetiole in profile
globular to subglobular, approximately 1.1 to 1.2 times higher than
long (LPpI 80 - 91); in dorsal view around 1.2 to 1.3 times wider than
long (DPpI 120 - 130). Postpetiole in profile appearing less voluminous
than petiolar node, in dorsal view approximately 1.3 to 1.4 times wider
than petiolar node (PPI 129 - 142). Mandibles unsculptured, smooth, and
shining; clypeus longitudinally rugulose, usually with three distinct
rugulae, median rugula better developed than remainder, rugulae often
with cross-meshes; cephalic dorsum between frontal carinae irregularly
longitudinally rugose to reticulate rugose, posteriorly towards
posterior head margin well reticulate-rugose, anteriorly towards
posterior clypeal margin more regularly longitudinally rugose (usually
with five to eight longitudinal rugae); scrobal area mostly
unsculptured; lateral and ventral head longitudinally rugose to
reticulate-rugose. Mesosoma laterally irregularly rugose, dorsally
distinctly longitudinally rugose. Forecoxae unsculptured, smooth, and
shining. Both waist segments laterally weakly, irregularly
rugulose/rugose, dorsally mostly unsculp- tured, smooth, and shining.
Postpetiole and gaster unsculptured, smooth, and shining. Ground
sculpture generally faint to absent everywhere on body. Whole body with
abundant, long, and fine standing hairs; first gastral tergite without
appressed pubescence. Anterior edges of antennal scapes with suberect
to erect hairs. Body colouration relatively variable, ranging from
bicoloured with head, mesosoma, legs, and waist segments yellowish to
bright orange contrasting with very dark brown to black gaster to whole
body uniformly brown.
