First record of Coleopterophagus albini Haitlinger 1990 (Acari: Astigmata: Canestriniidae) from Estonia and Norway

Abstract

The genus Coleopterophagus contains nine species: C. megnini (Berlese) known from Czech Republic, Croatia, England, Holland, Hungary, Italy, Poland, Serbia (Syrmia), Turkey and Ukraine, C. albini Haitlinger from Austria, Czech Republic, Germany, Poland, Romania and Ukraine, C. baali Haitlinger from Iran, C. belzebubi Haitlinger from China, Japan and Taiwan, C. dionizyi Haitlinger from Syria, C. donaldi Haitlinger from Italy and Ukraine, C. maroni Haitlinger from Romania, Syria and Ukraine and C. rudolfi Haitlinger from China. All these species are associated only with hosts belonging to the Protaetia Burmeister (Coleoptera, Scarabaeidae, Cetoniinae) (Berlese 1882, Cooreman 1954, Haitlinger 1988, 1990, 2002, 2012, Khaustov and Eidelberg 2001, Trach 2006, Trach and Khaustov 2011). Now, C. albini is found for the first time in Estonia and Norway. In Europe, only C. megnini and C. albini were noted in middle Europe in Germany and Poland. Localities of C. albini in Estonia and Norway placed farthest on north of Europe for species of the genus Coleopterophagus and in general for canestriniid mites. Flower beetles were collected during 8 July 1998 in Norway and 10 July 2009 in Estonia. Mites collected from Protartia (Potosia) metallica were mounted on microscopic slides in Berlese’s medium. Mites are studied using microscope NIKON Eclipse 50i. The terminology of idiosomal and leg chaetotaxy follow Grandjean (1939), Griffiths et al. (1990) and Norton (1998). Measurements are given in micrometers (μm).
