Clitemnestra menkei (Pagliano) comb. n.

Larrisson menkei Pagliano, 1995: 385, ♂. Holotype: ♂, Australia: Northern Territory: Litchfield National Park (originally G. Pagliano personal collection, Torino, Italy, now CAS).

NOTE.

The holotype has typical gorytine characters ( Bohart and Menke 1976): nonemarginate mandible, an omalus, midcoxae adjacent to each other, two midtibial spurs, and a basomedian ridge on sternum I, whereas in Larrisson the mandible is emarginate, there is no omalus, the midcoxae are separated, only one midtibial spur is present, and sternum I is simple. The following characters lead to Clitemnestra : hindwing media diverging more than one midocellar width beyond cu-a, scutum without oblique posterolateral carina, posterior veinlet of submarginal cell II longer than 0.25 of posterior veinlet of submarginal cell I, frons broader at level of midocellus than below it, omalus a fine seam ending ventrally well before reaching midline, and frons with long median sulcus (unlike most Clitemnestra , sternum VIII is emarginate apically). Three other characters that differentiate menkei from Larrisson are: free margin of clypeal lobe not concave laterally, antennal socket well separated from frontoclypeal suture, and hindocellus nearly touching orbit.
