Glaucopterum Wagner, 1963

Type species: Glaucopterum kareli Wagner, 1963 .

Glaucopterum Wagner, 1963: 8 ; Wagner, 1975: 373; Putshkov, 1975: 1 037, 1977: 373; Kerzhner, 1984: 41, 1997: 246; Schuh, 1995: 320.

Diagnosis. Moderate size, macropterous, elongate oval or ovate; general coloration varying from almost completely pale to dark brown, some species with dark speckles on dorsum (as in G. majus and G. zygophylli ); surface distributed silvery or brown, reclining and weakly widen setae; head declivitous, width longer than high; posterior margin of vertex straight; antennae not sexually dimorphic; labium not exceeding abdomen; tibial spines pale without clear dark spots at bases; length of tarsal segment II almost equal to that of segment III, tarsal segment I short; claws relatively large, slightly curving, pulvilli small, adnate to basal half of ventral claw surface at least; parempodia setiform. Male genitalia: vesica S-shaped or L-shaped, well sclerotized, with one or two apical spines; left paramere boat-shaped; right paramere lanceolate or truncate apically; phallotheca more or less curving, attenuated apically.

Host plants. Atraphaxis spp. (Josifor, 1993) ; Elaeagnus spp. , Lyceum spp., Nitratia spp., Zygophyllum spp. (Kerzhner, 1984) .

Remarks. Some species of Glaucopterum (as in G. atraphaxius ) are similar to Europiella spp. in the shape of right paramere, their right parameres truncate apically. But Europiella spp. is smaller in size and have tibial spines dark with clear dark spots at bases. Easily confused with species of Eurycolpus in coloration, but lateral margins of pronotum always concave in Eurycolpus .
