Gonapophyses IX linear to slightly curvilinear, average length 770.50–1977.16 µm, width 61.26– 142.98 µm; 13–17 prominent, widely spaced teeth, extending 2/3 of gonapophyses, variable in shape, ranging from rhomboid, and semi-rectangular to peg-shaped ( Figs 17 , 18 ); average height of teeth 9.40–18.16 µm; width 18.88– 19.59 µm; average space between teeth 18.05–20.83 µm; apex porrect to slightly curved in ventral view; surface variable; and apex serrate (except Purohita muiri ; Fig. 18A ).

Tropidocephalini currently includes 179 species in 35 genera, with most taxa restricted to bamboo ( Poaceae : Bambusoideae ) ( Bartlett 2010b ), except for some species of Tropidocephala on other grasses, for example T. andropogonis Horvath on Bothriochloa ischaemum (L.) Keng and Chrysopogon gryllus (L.) Trin. and T. tuberipennis (Mulsant & Rey) on Imperata cylindrica (L.) P. Beauv. all on grasses in the Panicoideae ( Holzinger et al . 2003 ) . New World Columbisoga (3 species), Macrocorupha gynerii Muir and Malaxa occidentalis Muir were reported on Gynerium Willd. ex P. Beauv. 1812 not Bonpl. 1813 ( Poaceae : Panicoideae : Gynerieae ), which is physiognomically but not phylogenetically, similar to bamboo. New World Tropidocephalini are restricted to Central and South America ( Bartlett 2010b ); however, taxa from the Old World are distributed in Australia , China , India , Indomalaya, and the Philippines ( Donaldson 1991 , Chen 2003 , Qin & Zhang 2010 ).
