1. N. josiahi species group

Diagnosis.

The Notomicrus josiahi group is diagnosed by the following combination of characters. Dorsal (outer) margin of protibia without notable robust seta at or near mid-length (Fig. 2a ). Body form elongate, strongly, but regularly attenuated posteriorly. Eyes large relative to head capsule. Elytra with notable contrasting dark and light colors (Figs 5 , 6 ); shiny and iridescent; microsculpture very fine. Prosternal process narrow (Fig. 3a ). Protibiae elongate, with penultimate dorsal seta only slightly longer than others on dorsal margin (Fig. 2a ); males with profemur lacking notable protuberance on posteroventral margin (Fig. 2a ), only weakly angulate at mid-length; protarsal claws very small, distinctly less than half the length of protarsomere V (Figs 2a , 8 , 9 ), not distinctly larger than female claws, anterior protarsal claw bifurcate, with small dorsal spur (Figs 8 , 9 ). The large eyes, elytral color pattern and coloration and characters of the protibiae, make this species group easily distinguishable from others. There are only two species known.
