Leurolophus Tuthill

L eurolophus Tuthill, 1942: 92 . Type species: L eurolophus vittatus Tuthill , by original designation and monotypy

When adding L. inopinatus to the previously monotypic genus L eurolophus, Burckhardt (1989) noted some important di erences (head shape, presence of costal break and absence of cellular pattern on membrane in the forewing) to L. vittatus , the type species. Despite these di erences, L. inopinatus was assigned to L eurolophus mostly on the basis of the paramere shape, and the egg which lacks an apical ®lament. Burckhardt and Lauterer (1989) recorded two specimens from Dominican amber which they referred to Tainarys . The present improved material base suggests that head and forewing structure in the adults, and the position of the anus in the larvae de®ne L eurolophus and Tainarys (cf. keys). The paramere shape is only super®cially similar, and presence or absence of an apical pedicel in eggs occur in other groups in closely related species (e.g. Aphalara, Burckhardt and Lauterer, 1997 ).

Here we transfer L. inopinatus to Tainarys (see below), and the fossil species from Dominican amber to L eurolophus . The latter resembles L. vittatus in the head shape, whereas the paramere is lamellar and the male proctiger indistinctly 2-segmented resembling L. oriformae . As L. vittatus and L. oriformae , the amber species lacks a costal break, bears a cellular pattern on the forewing mebrane, and has stout legs.
