Introduction

The only species in this genus is quite distinctive with orange and black colouring on the body and clear cells along the costal and apical margins of the wings which are otherwise brown. The head is anteriorly prominent but not conically produced as in Dysoliarus. The ear-shaped lobes of the postocular carinae on the pronotum are less prominent than those found in species of Rhigedanus and Dysoliarus.

Diagnosis

Morphology. Head. Vertex not lowered in relation to hind margin of pronotum, forming a common plane; 2.0–2.2× longer than wide, produced before eyes by 1/4–1/3 of an eye length; apex broadly truncate; caudal border v-shaped; lateral carinae strongly elevated; median carina incomplete, 1/4–1/2 as long as vertex. Frons at least 2.3× longer than wide, position of maximum width distinctly ventrad or around centre of frontoclypeal suture; lateral carinae slightly s-shaped, slightly widening at level of antennae (Fig. 13E); strongly elevated, lateral margins foliaceous, concealing base of antennae; median carina absent. Frontoclypeal suture semicircular, median part reaching at least lower margin of antennal scape; postclypeus with well developed lateral carinae and median carina; anteclypeus with well developed median carina. Thorax. Pronotum with undulating carinae, the latter strongly elevated medially forming poorly defined earshaped lobes; hind margin right or obtusely angled. Forewing 3.0–3.5× longer than wide; costa with 15–24 tubercles; concavity at costal border present or absent; Sc+R+M forming long common stem; fork of Sc+R distinctly basad of fork of CuA1+CuA2; r–m1 distad of fork MA–MP; position of icu at CuP distad of or at same level as apex of clavus; nine apical cells. Hind leg: tibia with three large lateral spines (basal spine shorter than others); six apical teeth in row interrupted by a wide gap; 1st tarsomere with (7–)8 apical teeth and no platellae; 2nd tarsomere with 11–12 (15 in one specimen) apical teeth and 9–10 (13, one specimen) platellae. Male genitalia. Phallotheca fimbriate below midlength. (Löcker et.al. 2006)
