Structure of some epidermal glands in the myrmecophilous beetle Adranes taylori (Coleoptera: Pselaphidae) [Insects]

Six morphologically distinct types of epidermal gland cells and their distribution are described from the pterothorax and abdomen of Adranes taylori. Four types are intimately associated with various groups of trichomes possessed by this beetle. All six types of gland cells are variations of class 3 gland cells. Types 1 and 2 resemble in morphology the sex pherome secreting gland cells of male Harpobittacus. Types 3a + b and 4a + b are similar to cells 2a + b in the defense glands of Eleodes and the cells comprising the pygidial glands of Bledius. Cell types 5 and 6 were not investigated in detail. However, type 6 is presumed to have a lubricating function due to its distribution.
