Tecmerium is characterized by the forewing with a short stripe extending obliquely from before middle of dorsum to the discal spot; the uncus keeled on ventral surface, the lateral arms of the gnathos fused with the tegumen, the distinct proximal flange, and the phallus dilated spherically at base in the male genitalia; the ovipositor divided into three membranous subdivisions posterior to the eighth segment, and the eighth sternum concave medially on the anterior margin in the female genitalia. These characters can help assign Tecmerium to Holcocerinae, although there are no distinct valid synapomorphies to define Tecmerium currently. Biology. Tecmerium anthophaga (Staudinger, 1871) was bred from the shoots of Lavandula stoechas L. ( Lamiaceae ) (Walsingham, 1901), and its host plants also included Rosmarinus sp. ( Lamiaceae ) and Thymelaea myrtifolia (Poir.) D.A. Webb (Thymelaeaceae) ( Robinson et al ., 2010 ); T. rosmarinellum (Walsingham, 1901) from Rosmarinus officinalis L. (Walsingham, 1901); T. spermophagia Walsingham, 1907 from seed-whorls of Phlomis purpurea L. ( Lamiaceae ) (Walsingham, 1907); T. polyphagum (Walsingham, 1908) from Artemisia canariensis (Besser) Less. , Allagopappus dichotomus (L.f.) Cass., Senecio kleinia (L.) Less., Sonchus gummifer Link (Compositae) , Pinus canariensis C. Sm. (Pinaceae) , Rubia fruticosa Aiton (Rubiaceae) , Cytisus proliferus L.f. ( Fabaceae ) and Rhus coriaria L. ( Anacardiaceae ) (Walsingham, 1908a). Tecmerium xylophagum (Walsingham, 1908) fed in the wood of a half-dead fig-tree (Walsingham, 1908b); T. florivora ( Meyrick, 1916 ) in the inflorescence of Mangifera indica L. ( Anacardiaceae ) ( Meyrick, 1916 ), and its host plants also included Arceuthobium oxycedri (DC.) M. Bieb. (Viscaceae) and Dendrophthoe glabrescens (Blakely) Barlow (Loranthaceae) ( Robinson et al ., 2010 ). Tecmerium catachlora ( Meyrick, 1916 ) did damage on the flowers of Leucas sp. and Leonurus sibiricus L. ( Lamiaceae ) ( Robinson et al ., 2010 ).
