Description
Description. Female. (Fig. 33B) N=8: Body length 25.26-29.89 (27.22); forewing length 17.65-20.82 (19.07); hindwing length 14.11-16.07 (14.77); pronotum length 6.69-7.85 (7.38); prozone length 2.17-2.62 (2.45); pronotum width 2.73-3.04 (2.92); pronotum narrow width 2.14-2.34 (2.25); head width 5.48-6.14 (5.92); head vertex to clypeus 2.12-2.39 (2.29); frons width 2.02-2.18 (2.10); frons height 0.73-0.88 (0.79); prothoracic femur length 6.97-8.17 (7.73); mesothoracic femur length 7.92-9.92 (9.15); mesothoracic tibia length 6.16-8.28 (7.38); mesothoracic tarsus length 6.16-7.53 (6.92); metathoracic femur length 8.38-10.01 (9.26); metathoracic tibia length 9.35-11.50 (10.46); metathoracic tarsus length 9.90-10.94 (10.42); pronotal elongation measure 0.32-0.34 (0.33); pronotal shape measure 0.37-0.42 (0.40); head shape measure 0.37-0.40 (0.39); frons shape measure 0.35-0.40 (0.38); anteroventral femoral spine count 14-16 (15); anteroventral tibial spine count 9-10 (9); posteroventral tibial spine count 8. Head (Fig. 45H): Juxta-ocular protuberances pronounced, the apex in the middle; the vertex between the parietal sutures is straight or slightly concave; vertex higher than the dorsal margin of the eyes. Frontal suture with a curved carina forming a continuous arc. Antennae pale proximally and fading to black or dark brown distally. Varying levels of black markings across the anterior surface of head, variable within the species; the vertex and juxta-ocular protuberances dark brown; two black spots medial to the parietal sutures. Terminus of palpi are darkened. Pronotum (Fig. 50D): Slightly elongate with a somewhat defined supra-coxal bulge; dorsal surface mostly smooth, but a few very small tubercles are present; prozone with parallel or divergent lateral margins prior to a rounded anterior margin; metazone with concave lateral margins with a medial bulge, exhibiting sparse small denticles in the posterior two thirds; posterior margin of the metazone rounded irregularly with a slight medial emargination. Supra-coxal sulcus strongly defined. The lateral margins of the pronotum slightly expanded to form a small ledge. Colored with black and pale markings that vary across specimens. Prothoracic Legs: Black and pale banding on posterior surface of femur with less than 10 tubercles; anterior (inner) surface with a proximal black stripe as well as a distal black stripe medially; ventral surface with a black mark distally and a black mark just medial to second most proximal posteroventral spine. Posterior prothoracic femoral genicular spine slightly smaller than posteroventral spines, originating just distal to the beginning of the genicular lobe. Prothoracic posteroventral tibial spines with the first and second most proximal and fifth through seventh shorter than the proximal third, fourth and terminal spines; the anteroventral spines longest at distal end and shortening proximally. Posterior surface of the prothoracic tibiae smooth with few black marks; anterior surface pale with black marks on dorsal margin, the ventral surface pale. Prothoracic coxae smooth with varying black markings on the posterior and ventral surface, the anterior surface with two black markings of varying size, one in the proximal half and one in the distal half. Meso- and Metathoracic Legs: Mesotarsi with first segment as long as the remaining segments combined. Metatarsi with first segment slightly longer than remaining segments combined. Wings: Fully developed, longer than the abdomen. Forewings mottled with contrasting regions of light and dark brown; the costal region alternating regularly from pale to dark its entire length; the costal region widened, the widest part being in the middle of the wing. The forewings have not been observed to be asymmetrically colored. Abdomen: Broad and smooth, widening from first segment until the beginning of the distal half (segments 4-5) when the lateral margins narrow gradually to the terminus, the middle being the broadest region. Tergites without posterolateral tergal projections. Cerci cylindrical, long and setose, tapering to a point. Supra-anal plate as long as wide, rounded.
