A. Maryanskanadachowska et Mm. Yang, KARYOTYPES AND MORPHOLOGY OF TESTES IN SOME SPECIES OF PACHYPSYLLINAEBECKER-MIGDISOVA (PSYLLOIDEA, SPONDYLIASPIDIDAE), Folia Biologica, 45(1-2), 1997, pp. 21-25
Karyotypes of four species of Pachypsyllinae were reinvestigated (Pach
ypsylla celtidismamma, P. celtidisvesiculum, P. venusta, Pachypsylla s
p. 2, and Tetragonocephala flava) in order to interpret contradiction
in the literature data. The morphology of testicular follicles for thr
ee species was described for the first time.
