Tribe Saccharosydnini Vilbaste

Description. Gonapophyses IX triangular (in dorsal view), average length 795.52–1119.49 µm, width 68.51–70.41 µm; 15–23 rhomboid teeth (Fig. 16), extending three quarters of inner lateral margin; apex variable ( Saccharosydne saccharivora [Fig. 16A] with apex blunt and imbricated with four small teeth; S. procerus apex conical with four ventral teeth).

Notes. Saccharosydnini currently includes 11 species in four genera, most New World except S. procerus (distributed in Japan, Taiwan, China, Korea and apparently Viet Nam; Fennah 1978, Bartlett 2014, Rossi-Batiz 2014). Plant associations are monocots, nearly all Poaceae (Rossi-Batiz 2014) . Saccharosydne saccharivora is a well-known sugarcane pest (e.g., Arocha et al. 2005), originally described on sugarcane in Grenada (Westwood 1833), but subsequently found on other grasses, such as Andropogon glomeratus (Walter) Britton, Sterns & Poggenb. and Andropogon bicornis L. (Metcalfe 1969).
