Therefore, we illustrated and described female, male and developmental stages of a new species, C. The present study is a part of a project which has the main objective of increasing the knowledge of this poorly studied regional mite fauna, especially that of Laelapidae. They also described and illustrated two new laelapid species, Hypospis dactylifera and H. During the last two decades, many new species of Cosmolaelaps were identified and illustrated by several authors worldwide ( Karg, 1995 Fouly et al., 1997 Bei et al., 2003 Ma et al., 2004 Bai and Wang, 2005 Karg and Schrolemmer, 2009 Joharchi and Halliday, 2011 Joharchi et al., 2011, 2012).īased on literature and updated information, there is rare or no previous knowledge about classification of predatory mites in Saudi Arabia until came Fouly and Al-Rehiayani (2011) who surveyed and described 38 species of predaceous mites belonging to different classification categories. In 1993, Casanueva raised most of the groups considered as subgenera to the generic level and put them in the subfamily Hypoaspidinae. This genus has been treated in previous studies either as a genus or as a subgenus of Hypoaspis Canestrini, 1885 ( Xu and Liang, 1996 Faraji and Halliday, 2013). Genus Cosmolaelaps Berlese consists of a large group of free-living predators in soil ( Evans and Till, 1979 Karg, 1995 Ma et al., 2004 Karg and Schrolemmer, 2009 Fouly and Al-Rehiayani, 2011). Some species in this family ecologically diverse, including obligatory and facultative parasites of vertebrates and insect pathogens ( Evans and Till, 1966 Strong and Halliday, 1994 Lindquist et al., 2009). The laelapid family is considered one of the most important groups of soil predatory mites, where it usually feeds on soil arthropods and nematodes ( Walter and Campbell, 2003 Joharchi et al., 2012). Mesostigmatid mites represent an important component of the belowground food web, where they are generally considered to be predators feeding on small arthropods, worms and nematodes ( Al-Rehiayani and Fouly, 2005 Joharchi and Halliday, 2011). nov (Gamasida: Laelapidae) from Agro-Ecosystem in Saudi Arabia. A New Laelapid Mite Cosmolaelaps qassimensis sp. were extracted from a pure laboratory culture, which were maintained feeding on the acarid mite, Tyrophagous putrescentiae Schrank and kept at 26☑☌ and 70±5% RH. Immature stages and adult female and male of C. There were no significant differences between average number of mites collected in May, July, August and October, while it was rarely found (1.25 and 0.96 mites/ sample) in January and February, respectively. qassimensis was at its highest rate of occurrence (13.96 individuals/ sample) in September.
