TYPE SPECIES : P. dimorion , n. sp. FIG. 48. Prophora dimorion , n. gen., n. sp. , in Burmese amber. A, C–E. Holotype male, AMNH Bu8783; B. paratype female, JZC 242. A . Head and thorax, oblique frontal view (male). B . Head, frontal view (female). C . Head and thorax, oblique posterior view. D . Body, lateral view. E . Male terminalia, right lateral view. ETYMOLOGY: Pro - (“first, before”), and - phora , common suffix for generic names in the Phoridae . The name is feminine. COMMENTS: The possession of a sulcus on the frons and great reduction in female sternites (which occur in stem-group and many crowngroup Euphorida), but more generalized venation of the Sciadocerinae , makes the phylogenetic position of this genus apparently close to the basal fork of the two lineages.
