Tribe Eodelphacini Emeljanov Description. Gonapophyses IX overall shape slightly sinuous, average length 1089.47–2244.07 µm, width 99.49– 88.99 µm, apical third of with 19–22 minutely lobed teeth (Fig. 7). Concave protuberance on inner margin adjacent to teeth; carination bordering apex (Fig. 7). Gonapophyses IX of Livatiella constellaris (Fig. 7A) exhibiting strong ridge sculpturing compared with Melanesia pacifica (Fig. 7B). Small pores or sensory structures covering gonapophyses IX. Notes. Eodelphacini has 26 species in 10 genera, distributed in Southeast Asia and the Indomalayan region. Plant associations are poorly known in the literature, with some exceptions Oryza sativa (Heong & Hardy 2009), and ferns (viz. Pteridum aquilinum (L.) Kuhn; Dennstaedtiaceae: Polypodiales; Chen & Hou 2012).
