Four new species of heteromorphic Dendrolaelaps males (Acarina: Rhodacaridae) in bark-beetle galleries in Poland.

Wisniewski, J.

Acarologia Vol 21 No. 2 pp. 149-162;


In 1974-75, heteromorphic males apparently of 4 different species of Dendrolaelaps were found in the galleries of bark-beetles in conifers near Poznan, Poland; these males were different from those of the 6 species of Dendrolaelaps known to have heteromorphic males, which are briefly described. It was concluded that these 4 species were new to science, and they are described, from the males only, as D. cornutohirschmanni sp.n., from under the bark of Picea abies; D. krantzi sp.n., from galleries made by Tomicus piniperda (L.) (Myelophilus piniperda) and Hylurgops palliatus (Gylh.) under the bark of Pinus sylvestris; D. lindquisti sp.n. from galleries made by Dryocoetes autographus (Ratz.) in Picea abies; and Dendrolaelaps hunteri sp.n. from galleries made by Pityokteines vorontzowi (Jacobs.) in Abies alba. The first 3 species were found in the Zielonka Forest near Poznan, and the fourth in the Swietokrzyski National Park.
