Metalimnobia (Metalimnobia) quadrinotata ( Meigen, 1818)

Species was previously unknown from the Korean Peninsula.

Diagnostic features. Yellowish brown species. Body length of male 8.4–12.7 mm, that of female 11.9–12.0 mm. Wing length of male 11.0– 15.3 mm, that of female 12.1–13.0 mm. Mesonotal prescutum obscure yellow with four distinct longitudinal dark brown stripes. Median stripes long, slightly wider frontally. Area, separating medial stripes, usually distinctly darker than ground color of prescutum, grayish brown, just frontally yellowish. Single specimen from South Korea has area, that separates median stripes, almost as light as ground color of sclerite, obscure yellow, what is common in specimens from Eastern Palearctic. Some, darker colored specimens from North Korea have this area nearly as brown as stripes themselves. Abdominal tergites I and II reddish brown, remaining tergites brown with blurred yellow lateral spots. Tergites VI–VIII in darker specimens lack yellow lateral spots, but have narrowly lightened posterior margins. Ninth tergite reddish brown. Proximal sternites yellow, distal sternites brown with grayish yellow posterior margins. Paramere of male genitalia bare apically, very apex with straight margin ( Fig. 10 ). Cercus of ovipositor ( Fig. 14 ) straight and narrow.

Elevation range. Altitudes from 200 m to 1900 m in North Korea.

Period of activity. Adults are flying from mid-June through beginning of October.

Habitat. Adults are met among old deciduous trees, where larvae develop under bark and in mushrooms.

General distribution. Species is widely spread in Eastern and Western Palearctic.
