Key to the Mecyclothorax Species   of Lanai

1. Head with two supraorbital setae each side; pronotum with lateral seta each side; elytral striae 1 and 2 evident at apex, though stria 2 may be shallower than sutural stria................................................... 2

19. Head with single posterior supraorbital seta each side; pronotum glabrous; sutural striae continuous, deep to elytral apex, but stria 2 obsolete, difficult to trace apically ( M. vitreus   group)....... Mecyclothorax flavipes   , new species

2(1). Discal elytral intervals with transverse-mesh microsculpture, sculpticell breadth 2–4 3 length; elytral stria 2 broad apically, nearly as deep as sutural stria at elytral apex; standardized body length 4.0– 4.5 mm ( M. ovipennis   group)........................................ M. mundanus (Sharp)  

29. Discal elytral intervals covered with well-developed isodiametric microsculpture, the sculpticells distinctly raised, producing a leathery appearance; elytral stria 2 traceable to apex, but distinctly shallower than sutural stria; standardized body length 4.5–5.3 mm ( M. palustris   group)....................................................... M. filipes (Sharp)
