Type material ( 17 ex. ): CENTRAL CHILE : Región Los Lagos : Chiloé prov. : NHMW (coll. Franz ); 1 ♂ ( holotype ); Chiloé Island , Chepu ; 20.II.1990 ; T . Cekalovic. – NHMW (coll. Franz ); 5 ♂ (4 without label of locality) and 11 ♀ (10 without label of locality) ( paratypes ); same data; T . Cekalovic . Comments: We have examined the types of this species and found that all the specimens ( holotype and paratypes ) belong without doubt to Achilia larvata ( Reitter, 1885 ) , one of the species we recently revised ( Sabella et al ., 2017 ). Therefore we here place Achilia validicorniformis Franz, 1996 as a junior synonym of A. larvata ( Reitter, 1885 ) ( syn. nov. ).
