Microcodides chlaena Gosse 1886
Microcodides chlaena (Gosse, 1886) This species was extremely common in the samples. It has previously been recorded in Europe (see e.g. Wulfert 1940; Berzins 1978), the former Soviet Union (Kutikova 1965; 1970) India (Sarma, 1988), Australia (Shiel & Koste 1979) and North and South America (Ha...
