Delabie, J.H.C., Mariano, C.S.F., Serrão, J.E., & Pompolo, S.G. 2004 The karyotype of the aberrant obligate ant-attended mealybug, Neochavesia caldasiae (Coccoidea: Pseudococcidae: Rhizoecinae) . Caldasia 26(1): 185-190

Notes: Information is given about the structure of the karyotype of the ant-attended mealybug Neochavesia caldasiae that maintains an obligate association with ants of the genus Acropyga. Seven pairs of holocentric chromosomes (2 = 14) constitute it, with one pair larger that the other six. This number is discussed according the to information available about the Pseudococcidae karyotype evolution, focusing the Rhizoecinae.
