Abstract
The Cimicidae (Hemiptera) are known to be blood ectoparasites primarily on birds and bats. Three species of the subfamily Haematosiphoninae are known from Argentina: Acanthocrios furnarii, Ornithocoris toledoi, and Psitticimex uritui; all feed on diverse avian hosts. The chromosome number and male meiosis of A. furnarii, and P. uritui from new Argentinean samples are analyzed and compared with previous data. The sample of A. furnarii described by Ueshima (1966) with 2n = 32 + XY (male), strikingly differs from the present results (2n = 10 + XY, male). The diploid number of P. uritui agree with the previously reported by Ueshima (1966), 2n = 28 + X 1 X 2 Y (male). Taxonomical implications about the identity of A. furnarii are discussed and the mechanisms of the karyotype evolution of species belonging to Haematosiphoninae are proposed.
