Remarks. Ameroseius furcatuswas originally described from Germany, where it was collected in a tussock of grass with roots ( Karg 1971a). Karg included this species to an identification key, without adequate morphological description. The species was only very briefly diagnosed by him, and based only on two accompanying illustrations, the epistome and dorsal shield. These illustrations were partly confusing because Karg drew the epistome as a flat structure having smooth anterior margin, and the dorsal shield bearing only 24 pairs of setae. The examination of the type material of A. furcatusshowed that the epistome is elongate and marginally serrate, and the dorsal shield possesses the normal 29 pairs of setae. Distinctive features of A. furcatusfemales include the peculiar presence of a pair of small rounded platelets between pseudo-metasternal platelets, short and rounded hyaline appendage on distal apex of movable cheliceral digit, and the insertion of JV3 on (ventri)anal shield, but they were neglected by Karg (1971a). I believe that the inconsistent original description of Ameroseius furcatus, especially the absence of comments on specific ventral features and a misinterpretation of the dorsal chaetotaxy ( Karg 1971a), led to description of the same species under the name Ameroseius pseudofurcatus. The latter has been thoroughly described and illustrated by Livshits and Mitrofanov (1975)from specimens from the Nikita Botanical Gardens, Crimea, from leaf litter under common hazel. I have not examined type specimens of that species, but I have a slide with numerous specimens (ten females, four males) from a mite collection of the Nikita Botanical Gardens, National Scientific Center, Yalta, Crimea (received from Alex Khaustov), collected in the type locality, and labelled as follows: Ameroseius pseudofurcatus, dub pushistyi, podstilka, gnbs( gosudarsennyi nikitskii botanicheskii sad), 9. 1. 1973 (leaf litter under downy oak, Quercus pubescens, State Nikita Botanical Gardens). From previously published descriptions ( Karg 1971a, Livshits and Mitrofanov 1975), observations of the primary type of A. furcatus, and examination of conspecific material from Germany, Crimea and Slovakia I have concluded that the both above mentioned species are identical and should be considered as synonymous.
