446. Tessinosoma caelebs Verhoeff, 1911

Tessinosoma ligurinum Verhoeff, 1930 .

Distribution

CH, IT-ITA.

Habitat

Forest, e.g., Alnus, Castanea, Quercus, Corylus, Populus; from 193–800 m a.s.l.

Remarks

The lack of males from the northern part of the distribution area of this species was interpreted by Verhoeff (1921) as “klimatisch-geographisches Parthenogenese”. This seems to have been the first time that the phenomenon “geographical parthenogenesis” was recognized (see Enghoff 1994).
