Morphology

Soldier

Head dark reddish brown; the anterior half of the mandibles black, the posterior half concolorous with the head; the middle of the labrum also concolorous with the head; thorax and abdomen brown, the ventral surface paler, legs pale yellow. Head densely covered with short pubescence, among which a few long hairs are scattered; thorax and abdomen with long and short hairs interspersed. Head slightly rectangular, flattened-cylindrical and stout, the sides nearly parallel, the posterior part slightly narrower, the posterior margin slightly arcuate and projecting. Labrum small, the anterior end bluntly rounded, the anterior margin and the sides colourless and transparent. Mandibles stout, flattened and broad at the base, each of the left and right mandibles with a large triangular inner-margin tooth at the middle. Antennae with 14 segments, segment 2 shorter than or equal in length to segment 3, segment 3 equal to or longer than segment 4. Postmentum elongated, slightly narrowed behind the middle. Pronotum very narrow, the anterior lobe erect and semicircular, the posterior lobe trapezoidal, the posterior margin slightly concave inwards.

Alate

Head, thorax and abdomen brown; anteclypeus white, postclypeus brown, labrum, mandibles, antennae, legs and wings yellowish brown. Body densely covered with fine hairs, the wing surface smooth and hairless. Head oval, short and broad; compound eyes medium-sized, ocelli elliptical, the distance between ocellus and compound eye about equal to the length of the ocellus. Postclypeus very highly arched, longitudinal length less than half the width, anterior margin straight, posterior margin wedge-shaped and extending backwards; anteclypeus equal in length to the postclypeus. Fontanelle a large round pit, situated at the centre of the vertex. Antennae with 15 segments, segments 2, 3 and 4 about equal in length. The middle part of the anterior margin of the pronotum nearly straight, the lateral ends slightly projecting forwards, the centre slightly concave. Radius sector of the forewing close to the anterior margin and extending to near the wing apex, without distinct branches; media arising independently at the humeral suture, situated between the radius sector and the cubitus, dividing after the middle into several branches that reach the wing apex; cubitus with about ten branches. Media of the hindwing arising fused with the radius sector at the humeral suture, likewise between the two, the remaining venation as in the forewing.
