A New Genus of the Eutrombidiinae Thor, 1935 (Acari: Eutrombidiidae) Parasitic on an Endemic Beetle from the South of Spain

Alhamitrombium tetraseta n. g., n. sp. (Acari: Eutrombidiidae: Eutrombidiinae) is described from two larvae ectoparasitic on Trymosternus bolivari Mateu (Coleoptera: Carabidae) from Almería, Spain. The new genus is distinguished from Hexathrombium Cooreman, 1944 and Beronium Southcott, 1986 on the basis of details of the coxalae. A key to the genera of larval Hexathrombiini is presented.
