Tribe Macropsini
Identification
From Hamilton 1983 (1):

"Members of the Macropsini are usually distinctive due to their greatly enlarged and obliquely striate pronota, although primitive genera of the tribe (e.g. Oncopsis) have less strongly developed pronota with transverse striae. Primitive Macropsini may resemble certain members of the Idiocerini (e.g. Idioceroides tettigoniformis Matsumura) but are distinguished by their emarginate genal lobes, trapezoidally-flattened hind tibiae and tegmina without an appendix as well as their much more strongly oblique antennal ledges which resemble those of the Agalliini and Megophthalmini.

The occipital apodemes of Macropsini (Fig. 7) are much less concave than those of Agalliini (Fig. 6) and Tartessini (Fig. 8), not bilobed, as in Eurymelini (Fig. 9) and Nioniini (Fig. l0), much shorter than those of Idiocerini (Figs. l, 5) and much larger than those of other tribes (Figs. 2-4, 11). Macropsini may be distinguished from Agalliini and Megophthalmini by the narrow and fully exposed prothoracic episterna and by their more or less trapezoidally-flattened hind tibiae with prominent, enlarged macrosetal bases. The distinctive shape of the hind tibiae demonstrate the monophyly of the tribe".
