Abstract: | The alienicolae of Patchiella reaumuri (Kaltenbach), which is heteroecious between Tilia x vulgaris Hayne and roots of Arum species, are here described from material reared on Arum maculatum L. and A. italicum Mill. in 1977. The sexupara morph is also described for the first time from specimens obtained in the same culture. Key couplets are offered whereby this morph can be separated from sexuparae of other British Pemphiginae. |
