Genus Paracodilia gen. n. Figures 1-9

Type species.

Paracodilia geniculata sp. n.

Etymology.

The generic name refers to the similarity between the new genus and Codilia Nielson, 1982.

Diagnosis.

General color deep brown. Crown light brown with distal 1/4 orange, pronotum and mesonotum pitchy without spots; eyes piceous; forewing with distinct yellow mark on clavus, veins without spots (Figs 1, 2). Face fuscous (Figure 3).

Anterior margin of head obtusely angled. Crown midlength produced distally beyond eyes, approx. 1⁄3 of entire length; area between eyes as wide as eye width, surface rugulose, elevated above eyes; lateral margins slightly carinate, not surpassing anterior margin of eyes, slightly convergent basally. Medial length of pronotum distinctly longer than crown and quite shorter than mesonotum (Figure 1). Forewings typical of subfamily (Figure 2). Clypeus long and narrow, lateral margins slightly convex; clypellus broad, maximum width approx. equal to midlength, base inflated, lateral margins constricted medially (Figure 3).

Male genitalia.

Valve triangulate in ventral view. Pygofer narrow in lateral aspect, caudodorsal margin produced and tapered in lateral view, without triangular plates at base (Figure 4), caudoventral processes short, covered with short spines, adjacent to base of caudodorsal processes (Figure 5). Segment X elongate, lateral margins parallel in ventral view (Figure 4). Aedeagus moderately long and narrow, somewhat tubular, bent at midlength in lateral aspect, apex asymmetrically bifurcate; gonopore apical on ventral surface between bifurcations (Figs 6, 7); dorsal connective absent. Connective large, Y-shaped with stem broad, shorter than length of arms (Figure 6). Style very long, much longer than aedeagus, sinuate in lateral view, tapered to acute apex (Figs 6, 8). Subgenital plate narrow, lateral margin abruptly tapered distally with dense setae (Figure 9).

Remarks.

This new genus is similar to genus Codilia Nielson, 1982 externally, but has very different male genitalia. The aedeagus is distinctly curved at midlength in lateral view and apex asymmetrically bifurcate, but in Codilia the aedeagus is slightly curved with a large retrorse spine at the apex. Also in the new genus the subgenital plate is highly setose laterally in its apical half but sparsely setose in Codilia .
