description: Camarotoscena Haupt, 1935
Camarotoscena Haupt 1935: 228.
Type species: Rhinocola speciosa Flor, 1861, by original designation.
Diagnosis: Adult. Head, in lateral view, deflexed 45–90° from longitudinal axis of body (Fig. 1C); in dorsal view, about as wide as thorax, moderately transverse. Vertex rhomboidal; covered in areolate-rugose microsculpture; passing smoothly into genae anteriorly; coronal suture fully developed; genae weakly produced ventrally but not enlarged into processes; frons elongate, parallel-sided to narrowly triangular (Fig. 3E); median ocellus not visible in perpendicular view to vertex; subgenae not differentiated into separate sclerites (Fig. 3E); compound eyes, in dorsal view, hemispherical, adpressed to head. Clypeus pear-shaped, moderate-sized, rounded ventrally, hardly visible in lateral view as it is hidden by genae. Antenna slightly longer than head width; flagellum with simple setae; segment 3 longest, as long as segments 4–5 together; segments 4, 6, 8, and 9 bearing each a subapical rhinarium lacking marginal spines. Thorax moderately slender; dorsal outline, in lateral view, weakly curved. Pronotum, in dorsal view, weakly curved posteriad laterally; propleurites subrectangular, divided by perpendicular suture into subequal epimeron and episternum. Metapostnotum with blunt tubercle. Mesosternum (Fig. 5B) narrower than head, forming transverse band more than three times as wide as long laterally; anterior margin weakly concave; pleurosternal suture hardly visible; basisternum triangular; katepisternum small antero-laterally, not bent dorsad laterally; angle of arms of precoxale obtuse. Pro- and mesotibiae cylindrical. Metacoxa with blunt, moderately long, horn-shaped meracanthus. Metafemur with the three ventral sense organs in the middle; apex with few stout long setae (Fig. 6O). Metatibia longer than metafemur, distinctly widened apically; bearing 9–12 slightly irregularly spaced apical sclerotized spurs and two to four peg-like setae adjacent to inner spurs (Fig. 7C). Both metatarsal segments relatively short, subequal in length. Forewing slightly subtrapezoidal; costal and anal margins subparallel or widening towards apex, 2.2–2.3 times as long as wide, membranous; vein C + Sc weakly, evenly convex, slender, distinctly delimited from cell; costal break developed, close to apex of vein R 1; pterostigma wide, entirely membranous; nodal line developed; veins R and M + Cu subequal; vein Rs relatively straight; vein M about as long as M 1 + 2; vein Cu 1a almost straight or weakly curved towards anal margin; veins M 1 + 2 and M 3 + 4 oblique to wing margin apically; anal break adjacent to apex of vein Cu 1b; surface spinules fine or coarse, spaced or dense, present in all cells. Hindwing slightly shorter than forewing; with one or two costal setae proximal to costal break and two clearly separated groups of two to four proximal and two to four distal setae, distal to costal break; vein R + M + Cu indistinctly trifurcating, base of vein Cu indistinct. Abdominal base with a sclerotized area on either side covered in spines. Aedeagus with simple proximal portion bearing many weak folds subapically; apex of distal portion not differentiated from stem. Female subgenital plate lacking apical process.
Last instar immature. Antenna seven segments; lacking sectasetae or lanceolate setae on antennal flagellum. Mid- and hindlegs without massive peg-like setae. Dorsal body surface lacking minute clavate setae. Precaudal abdominal tergites bearing densely spaced simple setae and sectasetae. Anus in ventral position; with additional pore fields developed.
Comments: Monophyletic with strong molecular support, morphologically supported by two homoplastic characters that we consider non-unique synapomorphies (Figs 10, 11; Supporting Information, File S4). The circumscription of the genus by Burckhardt and Mifsud (2003) is supported here. Included available species, distribution, and host plants are summarized in Table 3 and Supporting Information, File S3.
