A revision of the genus Ptochoryctis Meyrick, 1894 (Lepidoptera, Gelechioidea, Xyloryctidae) with the description of 12 new species

The genus Ptochoryctis Meyrick, 1894 is revised and reinstated in the Xyloryctidae (previously treated in Autostichidae) based on molecular and morphological evidence. A fuller description is provided of the morphology of all the species previously described in Ptochoryctis which are not combined elsewhere. The following new species of Ptochoryctis are described: Ptochoryctis blanchella sp. nov., P. caputanatis sp. nov., P. draconella sp. nov., P. flavalbella sp. nov., P. fuscilinea sp. nov., P. kitchingi sp. nov., P. marmorella sp. nov., P. minimella sp. nov., P. persicotincta sp. nov., P. ochraceella sp. nov., P. robinsoni sp. nov. and P. splendidella sp. nov.

Deloryctis Meyrick, 1934 is synonymised with Ptochoryctis. The following new combinations are established: Ptochoryctis corticivora (Meyrick, 1934), comb. nov. (which is consequently transferred from Depressariidae to Xyloryctidae), Metathrinca alma (Meyrick, 1908), comb. nov., M. inviolata (Meyrick, 1925), comb. nov., M. ochrograpta (Meyrick, 1923), comb. nov.; and M. perigramma (Meyrick, 1926), comb. no v.
