description: Genus Paracatonidia gen. nov.
(Figs 1–13)
Type species. Paracatonidia webbeda sp. nov., here designated.
Description. Width of head with eyes less than two-thirds width of pronotum. Vertex with disc slightly depressed, median carina protuberant, obsolete apically, anterior margin carinate, subtruncate, lateral margins carinate and straight, diverging basad, posterior margin broadly concave (Fig. 3). Frons slightly convex in lateral view (Fig. 5), upper margin roundly concave, median carina percurrent, lateral margin carinate, sinuately diverging to below level of antennae then gradually incurved to suture (Fig. 4). Clypeus with median and lateral carinae distinct (Fig. 4). Rostrum slightly exceeding base of post-trochanter, with length of subapical segment equal to apical segment. Antenna subglobose, not sunk in a depression (Fig. 5). Ocelli separated from eyes (Fig. 5). Eyes excavate beneath (Fig. 5), not overlapping pronotum in dorsal view (Fig. 3). Pronotum with length in midline as long as length behind eyes, anterior margin of disc roundly convex, posterior margin subangulately excavate about 115 degrees; median carina distinct, lateral carinae diverging posteriorly, not reaching hind margin; lateral lobe with a longitudinal carina between eye and tegula (Fig. 3). Tegula with a longitudinal carina in middle (Fig. 3). Mesonotum with three carinae more or less obsolete (Fig. 3). Forewing with costal margin slightly convex; apical margin roundly convex; posterior margin angulately excavate (155 degrees) at apex of clavus; vein Sc+R forking slightly basad of Cu1 forking; vein Sc with several branches, directed towards anterior margin; veins R and M with two and five apical branches, respectively; vein Cu1 forking slightly distad of Sc+R fork, equal to level of union of claval veins, with Cu1b two-branched; clavus terminating at middle of forewing (Fig. 6). Hindwing with two, two and three branches of veins R, M and Cu1, respectively; vein A2 with blind branches (Fig. 7). Post-tibiae with one lateral spine.
Male genitalia. Anal style distinctly exceeding apical margin of anal segment (Fig. 8). Pygofer in lateral view with dorsal margin distinctly shorter than ventral margin (Fig. 9), medioventral process divided into two branches (Fig. 10). Genital style with a stout, ear-like process and a finger-like process rising from apical third and near base of dorsal margin, respectively (Fig. 11). Aedeagus with phallobase sheath-shaped, two dorsal, two lateral and one ventral lobe with anterior portions connected together, protruding anteriorly into body cavity (Figs 12–13). Suspensoria suspended phallobase with dorsolateral portions of pygofer. Genital lamina sclerotized (Fig. 12). Phallobasal conjunctival processes exceeding apical margin of phallobase, with apex broadly webbed like a duck foot (Figs 12–13). Sheath extremely developed, broad, twisted and membranous (Fig. 12). Connective relatively stout and short (Fig. 12).
Etymology. The genus name, which is masculine, is a combination of “para-” (similar to) and “ Catonidia ” (name of the related genus), and indicates the new genus is similar to the genus Catonidia Uhler.
Host plant. Unknown.
Distribution. Oriental region (southwestern China).
Diagnosis. The genus is readily distinguished from other known genera in the tribe Achilini by the tegula having a longitudinal carina in middle (Fig. 3), the medioventral process of the pygofer having two branches (Fig. 10), the phallobasal conjunctival process with apex broadly webbed duck-foot like (Figs 12–13), and the sheath extremely developed, broad, twisted and membranous (Fig. 12).
