Redescription. Coloration: Body mostly pale testaceous. Second segment of antennae brown and base narrowly testaceous; stripes and spots on anterior and posterior pronotal lobe, apex of discal tuberculous spines, apex of lateral expansions on posterior pronotal lobe, confluent spots on propleura, ventral surface of abdomen, intermediate spines on second segment of connexivum, suffusion on corium, tarsi (except apical portion of second segment and basal portion of third segment testaceous), apical portion, and a wide median annulation on tibiae, mid and hind femora (except base, apex, and a median suffusion testaceous), black ( Figs. 1 , 2 ). Most tubercles on body and apical spine on scutellum testaceous, very narrowly whitish apically; anterior femora with faint brownish suffusion basally; membrane of forewings brown with whitish confluent spots and fuscous suffusion basally; hindwings infumate, venation darker.

Structure: Body large and dorso-ventrally depressed. Body clothed with tubercles. Basal segment of antennae moderately thick with setigerous tubercles and apical spine, second segment somewhat compressed and much longer than basal one, apical 2/3 of third segment and fourth segment, setose; anteocular considerably shorter than postocular, head moderately elongate with a spine on antennal tubercles at upper margin of eyes, at lateral emargination of eyes, and a pair of spines on vertex; eyes subpedunculate, kidneyshaped in lateral view; ocelli small, protuberant, and narrowly separated ( Figs. 1 , 2 ); basal rostral segment with trapeziform tubercles (apical angles rounded), second segment subequal in length to third and fourth segments combined ( Fig. 2 ). Pronotum wider than long; collar processes short, with tubercles (apical angles rounded) laterally; discal tuberculous spines of anterior pronotal lobe erect and long; posterior pronotal lobe tuberculate and with long spines and significant lateral expansions; prosternum with spines at externo-apical angle ( Fig. 2 ); scutellum tuberculate and with erect spine apically; lower surface of anterior tibiae and femora with short dense denticles, femora with spines and tubercles. Connexival segments with a variable number of spines at external apical angle ( Fig. 1 ), abdomen with flattened area midventrally. Pygophore oblong, ventral surface clothed with rounded tubercles and short setae ( Figs. 3, 9, 10 ); paramere falculate, preapical portion with numerous long setae ( Figs. 7, 8 ); basal plate short, basal plate prolongation thin, curving, and sclerotized throughout ( Fig. 4 ); phallotheca sclerotized dorsally and laterally, membraneous ventrally, symmetrically arranged in its interior; struts long, divided into two principal portion, basal potion (strut A) situated ventrally, dorsal portion (strut B) whiplike, recurved and extending outside of the principal body of phallus ( Figs. 4–6 ).
