Paramnemyne Heller, 1895: 10 Figs 12 , 88

Type species.

Paramnemyne arcana Heller, 1895 [by subsequent designation: Rheinheimer 2011: 78].

Gender.

Feminine.

Diagnosis.

Paramnemyne can be readily distinguished by the transverse carina near the posterior margin of the metaventrite, marking the end of the rostral channel (Fig. 12 ). The second antennal funicular article is several times longer than the first; the femora are not carinate, are ventrally toothed, and are unarmed at the apices; the mesopleura are small and non-ascending; and the eyes are completely separated with the greatest separation in the middle.

Phylogenetic relationships.

The unarmed femoral apices, small and non-ascending mesopleura, and piazurine type of mesoventrite suggest improper placement in the Lechriopini , however transferring the genus without observing the putative relatives of Paramnemyne , the South American genera Mnemyne (sec. Heller 1895: 11) and Paramnemynellus Hustache, 1932 (sec. Hustache 1932b: 207), would be remiss.

Host associations.

Unknown.

Described species.

Two species are known from the focal region and three additional species are known only from South America ( Wibmer and O’Brien 1986: 270).

Range.

Mexico, Guatemala, Costa Rica [ O’Brien and Wibmer 1984: 296], Panama; South America.
