<paragraph box="[118,1122,912,1581]" pageId="58" pageNumber="59" type="mainText">Head weakly longer than wide (CI 97-98); posterior head margin moderately concave. Anterior clypeal margin medially impressed. Frontal carinae strongly developed, diverging posteriorly, and ending at corners of posterior head margin. Antennal scrobes developed, moderately deep, but narrow and without defined posterior and ventral margins. Antennal scapes short to moderate, not reaching posterior head margin (SI 78-83). Eyes small to moderate (OI 21-24). 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 38-41). Propodeal spines extremely long, spinose, and acute (PSLI 60-65); propodeal lobes well-developed, triangular to elongate-triangular, and acute. Petiolar node in profile rectangular nodiform but comparatively high, approximately 1.2 to 1.3 times higher than long (LPeI 79-83), anterior and posterior faces approximately parallel, posterodorsal margin situated higher than anterodorsal, dorsum convex; node in dorsal view approximately 1.2 times longer than wide (DPeI 82-86). Postpetiole in profile subglobular and anteroposteriorly compressed, approximately 1.2 to 1.3 times higher than long (LPpI 77-81); in dorsal view around 1.1 times wider than long (DPpI 104-112). Postpetiole in profile higher and less voluminous than petiolar node, in dorsal view approximately 1.3 to 1.4 times wider than petiolar node (PPI 127-138). Mandibles distinctly longitudinally rugose; clypeus longitudinally rugulose, with one to six rugulae, median rugula always present, remaining rugulae variably developed; cephalic dorsum between frontal carinae with six to nine longitudinal rugae, most rugae running unbroken from posterior head margin to anterior clypeus, few rugae interrupted and none with cross-meshes; scrobal area mostly unsculptured; lateral and ventral head longitudinally rugose, very rarely with cross-meshes. Mesosoma laterally and dorsally distinctly longitudinally rugose. Forecoxae unsculptured, smooth, and shining, with weak, superficial ground sculpture. Waist segments strongly and very regularly longitudinally rugose, rugae absent from anterior face, but running unbroken from one side to other through posterior face. Base of first gastral tergite distinctly costulate, remainder of gaster unsculptured, smooth and shining. Ground sculpture generally faint to absent everywhere on body. All dorsal surfaces of head, mesosoma, waist segments, and gaster with abundant, long, and fine standing hairs; first gastral tergite without appressed pubescence. Anterior edges of antennal scapes suberect to erect hairs. Body uniform dark brown to black in colour.</paragraph>

Both are described as new and distinct species here, but it is possible that they are conspecific. Their general appearance is very much alike, and differentiating between the two requires measuring a few key characters.
