Key to genera of Neotropical Agapophytinae

1. Antennal scape bulbous, distinctly thicker than pedicel and flagellum, with numerous strong erect macrosetae (Fig. 47); scutellum usually with two pairs of macrosetae.............................................................. 2.

- Antennal scape similar in width to remaining segments, rarely thicker, macrosetae setae variable; scutellum usually with one pair of macrosetae..................................................................................... 3.

2. Prosternum with setae medially; genal setae white with tuft of erect black setae below eye; wing hyaline, mottled or dark infuscate with distinct fenestrations; male with single row of postocular macrosetae dorsally, absent on occiput; palpi slender Pachyrrhiza Philippi.

- Prosternum without setae; genal setae uniformly dark; wing smoky infuscate, darker anteriorly; male with elongate macrosetae scattered on postocular ridge and on occiput; palpi thickened (Figs 45–47)........................ Pachylopella gen. n.

3. Antennae longer than head, scape longer than flagellum; lower frons and face distinctly rounded and bulbous-like, parafacial setae present; palpi thickened.................................................... Sigalopella Irwin & Winterton.

- Antennae shorter than head (Fig. 33A, B), or if similar to head length, then scape not longer than flagellum (Fig. 33C, D); lower frons and face flat or at most slightly rounded, parafacial setae absent; palpi slender................................ 4.

4. Body yellow-orange to grey pubescent (e.g., Figs 5, 14, 31, 36); wing hyaline to pale infuscate, sometimes mottled or fenestrate (Fig. 13A, B)............................................................................ Entesia Oldroyd.

- Body predominantly black (sometimes with orange ventrally on thorax), wing uniformly dark infuscate, darker anteriorly (Figs 13C; 38–40)...................................................................... Melanothereva Malloch.
