Gnatheulia Razowski 1997

Gnatheulia Razowski, 1997 Gnatheulia Razowski 1997: 82; Brown 2005: 352. Type species. Gnatheulia gnathocera Razowski, 1997. Remarks and Diagnosis. Razowski (1997) described Gnatheulia for the single species G. gnathocera, known only from the holotype male collected in Cajamarca Province, Peru. It has remained the only species in the genus, and the holotype the only known specimen.According to Razowski (1997), the “…shapes of the uncus, gnathos, and valva are probable autapomorphies of this monotypic genus.” The most conspicuous features of the male genitalia are the paired lateral processes of the gnathos, which are nearly three times as long as the apically-joined median plate; the lobe-like swelling at the base of the costa of the valva; and the slightly rounded-upturned apical one-fifth of the valva. Distribution and biology. The discovery of a new species from Argentina, described below, significantly expands the range of the genus from Peru to Argentina. The life history remains unknown.
