Type species: Jacobsonina simplex Hebard, 1929 . Roth 1993: 282 ; Wang et al. 2009: 751 ; Wu et al. 2014: 275 . Generic diagnosis (Mainly after Roth (1993) , Wang et al . (2009) and Wu et al. (2014)) . Sexual dimorphism indistinct. Body small, usually yellowish brown. Interocellar distance slightly wider than the distance between the eyes, narrower than the distance between antennal sockets. Pronotum subelliptical, equal in length to width, disc usually with symmetrical spots and stripes. Tegmina and wings fully developed, both extending beyond the end of abdomen. Anteroventral margin of front femur Type B 3 . Tarsal claws symmetrical and unspecialized. Abdominal terga of male unspecialized, or only the seventh or first tergum specialized, with a glandular area. Supra-anal plate symmetrical, paraprocts dissimilar. Male subgenital plate asymmetrical, without styli. Accessory sclerites complicated. FIGURE 1. Maximum likelihood (ML) tree based on COI sequences.
