; see Goloboff, 1982, 1995); presumably, receptacles with thin, weak ducts may easily get broken during moults, producing minor differences in successive moults of the adult female. A conservative approach is followed here, considering as conspecific those females with general agreement in their morphology despite minor differences in spermathecal shape. Future work may well reveal that some of the species recognized here represent in fact more than one species.
