Identities of lance flies (Diptera: Lonchaeidae) described by de Meijere, with notes on related species.

Abstract: The seven species of Lonchaeidae described by de Meijere from south-east Asia (all placed by him in the genus Lonchaea) are redescribed, compared with their relatives, and assigned to their proper genera: Lonchaea minuta, L. pugionata, Silba gibbosa, S. lucens, S. obscuripennis, S. setifera (all from Java), and S. cupraria (from Krakatau). Lectotypes are designated for all except cupraria which is known from the holotype only. L. minuta is a prior name for lambiana Bezzi (= longicornis Lamb). S. obscuripennis (= zopherosa McAlpine) is a junior synonym of S. atratula (Walker). Three new species, L. marshalli from Natal, L. hennigi from Formosa, and S. vanemdeni from Malaya, are described. Keys to the world species of the L. impressifrons and of the S. abstata groups of species are provided. The genitalia of 16 species are figured
