Prophora , new genus

DIAGNOSIS: Proleg stridulatum present (seen in holotype specimen only); frons with well-developed median sulcus, one pair of fronto-orbital setae in both sexes; one pair of interfrontals in male, 3 pairs in female; one pair of verticals in male, two pairs in female; basal flagellomere not sexually dimorphic in size; one pair of dorsocentrals, two pairs of scutellars present; sternites well developed in male, lost in female except for terminal two sternites (7 and 8); lacking wing-vein characters of Euphorida (i.e., chars. 19–24 in table 4, fig. 43).

TYPE SPECIES: P. dimorion , n. sp.

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.
