Pristiphora (Lygaeonematus) gerula ( KONOW 1904)

For references to this and following species see LACOURT, 1999 and TAEGER & BLANK, 2011.

Types: In KONO ẃs collection in DEI, Müncheberg, there are two syntypes (1 , 1 ). A male is labelled „Mecklenburg, Fr. W. Konow p. (printed), Klkh (= Kalkhorst bei Strelitz), 8.5.89 (handwriten); Coll. Konow (printed); Type (red label); Lygaeonematus gerulus Knw, Kalkh. 5.89 (written in Konow´s handwritting); O. Conde det. Lygaeonematus saxeseni Htg. (printed)“. The female bears labels „ Coll. Konow (printed); Type (red printed label); Pristiphora saxesenii Hartig. determ. Muche 1972 (handwritten); Lectotype; Pristiphora gerula (KONOw) , det. BeneŠ 1990“;. The female syntype is hereby designated as a lectotype of this specis .

Both specimens are pinned on minutia on the same kind of sheet; male in perfect condition, female with apical three segments of right antenna missing when examined in vii.1990.

Differential diagnosis: Very similar to P. (L.) jacutica , from which it can be separated by absent scopa of the sheath and oblique basal annuli of the lamnium in the female, and shape of penis valve in the male. From saxesenii it differs by dorsally black abdomen, yellow stigma, black mesepimeron, valvula 1 without ctenidia and prominent serrulae, and obsolescent annuli in apical part. From P. (L.) ezumatsuvora and P. (L.) harai it differs by at least partly pale underthorax and much shorter sheath, and from other species of the compressa –complex it can be safely distinguished on smooth and shining epipygium and shape of sheath.
