Woldaia Brown and Hodkinson, stat. rev.

Woldaia Brown and Hodkinson 1988: 49.

Type species: Woldaia nebulosa Brown and Hodkinson, 1988, by original designation and monotypy.

Diagnosis: Adult. Head, in lateral view, deflexed 45–70° from longitudinal axis of body (Fig. 1L); in dorsal view distinctly narrower than thorax moderately transverse. Vertex subrectangular; covered in imbricate microsculpture; passing smoothly into genae anteriorly; coronal suture fully developed; genae weakly produced ventrally but not enlarged into processes; frons small trapezoidal; median ocellus clearly visible in perpendicular view to vertex; compound eyes, in dorsal view, hemispherical, adpressed to head. Clypeus pear-shaped, large, flattened ventrally, visible in lateral view. Antenna 10-segmented, distinctly longer than head width; segments 3–5 with indistinct bifid setae; segment 3 longest, shorter than segments 4–6 together; segments 4, 6–9 bearing each a subapical rhinarium lacking marginal spines. Thorax relatively robust; dorsal outline, in lateral view, weakly curved. Pronotum, in dorsal view, weakly curved posteriad laterally; propleurites narrowly subrectangular, divided by perpendicular suture into larger epimeron and smaller episternum. Metapostnotum laterally compressed. Mesosternum as wide as head, forming transverse band more than three times as wide as long laterally; anterior margin weakly concave; pleurosternal suture not visible; basisternum indistinct; katepisternum small antero-laterally, not bent dorsad laterally; angle between arms of precoxale obtuse. Pro- and mesotibiae cylindrical. Metacoxa with blunt horn-shaped meracanthus. Metafemur with the three ventral sense organs in medial position; apex with a group of stout long setae.Metatibia as long as metafemur, slightly widened apically; bearing 9 or 10 irregularly spaced, apical, weakly sclerotized spurs that may be on raised processes, without posterior peg-like or thorn-like setae. Both metatarsal segments relatively short, subequal in length. Forewing ovate, widest in basal third; 2.3 times as long as wide, membranous; vein C + Sc evenly convex, broad, indistinctly delimited from cell; costal break lacking; pterostigma wide, entirely membranous; nodal line absent; veins R and M + Cu subequal; vein Rs weakly sinuous; vein M longer than M 1 + 2; vein Cu 1a 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 present in all cells. Hindwing slightly shorter than forewing; with one costal seta proximal to costal break and seven ungrouped 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 proximal portion strongly subdivided subapically; apex of distal portion differentiated from stem. Female subgenital plate bearing apical process.

Last instar immature. Antenna 10 segments; bearing sectasetae or lanceolate setae on antennal flagellum. Mid- and hindlegs without massive peg-like setae. Dorsal body surface bearing minute clavate setae. Precaudal abdominal tergites lacking densely spaced simple setae or sectasetae. Anus in terminal position; with additional pore fields developed.

Comments: Woldaia is monotypic, currently including only W. nebulosa Brown and Hodkinson 1988: 49, comb. rev. (from Diclidophlebia, Burckhardt and Mifsud 2003: 14). Its distribution and host plants are summarized in Table 3 and Supporting Information, File S3.
