Kinonia Ball, 1933 n. rec.

Kinonia Ball, 1933: 224 (Type: Kinonia elongata Ball, 1933 , by original designation).

Diagnosis. Head acutely produced in dorsal and lateral view. Ocelli on anterior margin of crown. Frontoclypeus straight in profile, clypeal sulcus prominent. Forewing rounded apically, usually not extended to apex of abdomen, branches of R not strongly reflexed, usually with three anteapical cells, inner anteapical cell open basally, appendix absent. Pygofer side with short tooth on apical half near ventral margin. Valve long, triangular. Style preapical angle distinct. Connective H-shaped. Aedeagus with shaft relatively short and broad in lateral and posterior view, hinged at the base.

Distribution. Mexico; USA.

Remarks. This genus only includes the type species, Kinonia elongata . Emeljanov (1962) treated it as a junior synonym of Stirellus but Oman et al. (1990) retained Kinonia as a valid genus. Although it is similar to Stirellus , as delimited here, in most respects, it differs in having the aedeagus relatively broad and hinged at the base of the shaft, a trait characteristic of most Chiasmini Distant. Thus, further analysis may show that this genus may be more appropriately placed in the latter tribe. Nevertheless, Kinonia agrees with the current definition of Stenometopiini in other respects and phylogenetic analysis of combined morphological and molecular data placed this genus as sister to Stirellus with strong branch support ( Zahniser & Dietrich, 2013). Kinonia was originally described from the southwestern USA. It is here recorded from Mexico for the first time.
