Disholandricus lasius

(Ashmead, 1896)

Disholandricus lasius is a cynipid gall wasp that induces galls on oak . Formerly classified in the Andricus, this species was reassigned to Disholandricus based on phylogenetic and morphological studies. Like other members of the Cynipidae , the manipulates host plant tissue to form a protective structure that houses and nourishes its developing larvae. The species exhibits the complex typical of oak gall wasps, involving both sexual and that alternate between different plant structures or host species.

Taxonomic history

This was originally described by Ashmead in 1896 as Callirhytis lasius, later transferred to Andricus, and subsequently moved to Disholandricus following molecular phylogenetic studies that reorganized the Cynipini tribe. The Disholandricus was erected to accommodate species previously placed in Andricus that form a distinct clade based on genetic and morphological data.
