Midoria Kato

Midoria Kato, 1931: 439 . Type species: Midoria capitata Kato, 1931 .

Diagnosis. Similar to Thlasia but smaller, with head less strongly produced and aedeagus shaft compressed, with one or two pairs of moderately long processes subapically on posteroventral surface.

Description. Body small, length about 6.0–8.0 mm, usually brown or light brown. Head foliaceous, anterior margin rimlike, slightly wider than or equal to greatest width of pronotum. Median length of vertex shorter than width between eyes. Pronotum broad, often with irregular patches or spots; scutellum nearly triangular. Forewing usually with brown tubercles or spots and with additional cross veins in corium beyond outer apical cell.

Male pygophore slightly longer than high, with long ventrolateral processes, ventral margin rather expanded. Aedeagus shaft compressed, with one or two pairs of moderately long processes subapically on posteroventral surface. Connective T-shaped in ventral view. Paramere elongated with recurved apex and slender anterior portion.

Notes. The identity of this genus is somewhat uncertain because the type material of the type species is apparently lost (see discussion below). Here we follow the definition of the genus proposed by Cai and Jiang (2000).

Size. Length (including tegmen): 6.0– 8.0 mm.

Distribution. Oriental Region.
