<paragraph box="[118,1122,877,1543]" pageId="20" pageNumber="21" type="mainText">Head distinctly longer than wide (CI 93-95). Posterior head margin concave. Anterior clypeal margin medially impressed. Frontal carinae strongly developed, strongly diverging posteriorly, and ending at corners of posterior head margin. Antennal scrobes developed, but shallow, narrow, and without defined posterior and ventral margins. Antennal scapes comparatively short to moderately long, not reaching posterior head margin (SI 79-85). Eyes short to moderately sized (OI 20-21). Mesosomal outline in profile flat to weakly convex, moderately marginate from lateral to dorsal mesosoma; promesonotal suture and metanotal groove absent; mesosoma comparatively stout and high (LMI 37-39). Propodeal spines long to very long, spinose, and acute (PSLI 38-42); propodeal lobes well-developed and comparatively long, elongate-triangular, and acute. Petiolar node in profile rectangular nodiform with sharply defined angles, between 1.0 to 1.1 times higher than long (LPeI 93-98), anterior and posterior faces approximately parallel, anterodorsal and posterodorsal margins approximately at same height, dorsum straight; node in dorsal view around 1.3 to 1.4 times longer than wide (DPeI 72-76). Postpetiole in profile globular to subglobular, approximately 1.1 times higher than long (LPpI 87-95); in dorsal view 1.0 to 1.1 times wider than long (DPpI 102-112). Postpetiole in profile appearing less voluminous than petiolar node, in dorsal view approximately 1.3 to 1.4 times wider than petiolar node (PPI 135-143). Mandibles distinctly longitudinally rugose; clypeus always with a very well-developed and pronounced longitudinal median ruga and few much weaker, and often broken lateral rugae/rugulae; cephalic dorsum between frontal carinae with seven to ten longitudinal rugae, most rugae running unbroken from posterior head margin to posterior clypeus, rugae only very rarely with cross-meshes; lateral and ventral head usually longitudinally rugose, sometimes partly reticulate-rugose. Mesosoma laterally and dorsally distinctly longitudinally rugose. Forecoxae usually completely unsculptured, smooth, and shiny, sometimes with partial superficial sculpture. Waist segments longitudinally rugose. Ground sculpture generally faint to absent everywhere on body. First gastral tergite unsculptured, smooth, and shining. All dorsal surfaces of head, mesosoma, waist segments, and gaster with abundant, long, and fine standing hairs. Anterior edges of antennal scapes with suberect to erect standing hairs. Body colour uniformly bright orange to orange-brown.</paragraph>
