Key to species of Engelimyia (males only)

1. Sternite 5 with median part at most slightly raised, in lateral view with a blunt angle between anterior and posterior halves and posterior half with a more or less triangular appearance ( Figs 5 , 35 ). Surstylus simple apically ( Figs 4 , 34 ). Pregonite with strongly curved, uninterrupted dorsal margin and simple tip ( Figs 7 , 37 ) .................................. 2

­ Sternite 5 with median part abruptly raised, in lateral view with a right angle between anterior and posterior halves and posterior half more rectangular or quadratic than triangular ( Figs 13 , 27 ). Surstylus apically bifid, either very clearly ( Fig. 12 ) or more concealed when the division is in the sagittal plane ( Fig. 26 ). Pregonite with gently curved dorsal margin and an apical or subapical notch ( Figs 15 , 29 ) ........................... 3

2. Cercus in lateral view with distinctly truncated apex ( Fig. 3 ). Surstylus almost triangular, anterior free margin at most slightly concave. Lateral stylus with large, curved pro­

jection at base, apical membranous structure with moderately constricted base, vesica triangular, phallic tube dorsally bulging but without distinct projection proximal to juxta ( Figs 8 , 39 ) .................................................................................................... bosqi ­ Cercus in lateral view with subapical dorsal hump and apico­dorsal sinuous outline ( Fig. 33 ). Surstylus with median restriction (i.e., anterior free margin strongly concave or sinuous), distal part rounded and distinctly set off ( Fig. 34 ). Lateral stylus with small flap­like projection at base, apical membranous structure with strongly constricted base, vesica almost quadratic, phallic tube dorsally with triangular projection proximal to juxta ( Figs. 38 , 42 ) ................................................................. qibos sp. nov.

3. Sternite 5 with its median projection recurving anteriorly ( Fig. 13 ). Cerci asymmetrical in posterior view, apico­median margin of right cercus slightly overlapping left cercus ( Fig. 10 ). Surstylus with apex bifid in the transverse plane, prongs almost aligned in lateral view but lateral (or outer) prong slightly shorter than median (or inner) prong ( Fig. 12 ). Juxtal apophyses long ( Figs 16, 17 , 40 ) ............................ inops

­ Sternite 5 with its median projection abruptly ending and not recurving ( Fig. 27 ). Cerci symmetrical in posterior view ( Fig. 24 ). Surstylus with large, saddle­like bifurcation apically, prongs distinctly visible in lateral view ( Fig. 26 ). Juxtal apophyses short ( Figs 30 , 41 ) ..................................................................................... psino sp. nov.
