— Forewing longer and narrower with a more angular apex, broadest in basal half.................. 3

2(1). Forewing membrane somewhat opaque, amber colored, with a restricted speckled pattern around the stem of vein R+M+Cu; cell m 1 large: vein Cula evenly convex anteriorly; costal break distinct. Head and thorax dark orange and fuzzy. Genal processes cone-shaped........ K. grandiceps Crawford

— Forewing (Fig. 104) membranous, weakly infuscate with a transverse brown banding pattern across the apical margin; cell m 1 smaller; vein Cula slightly sinuous; costal break indistinct. Genal processes (Fig. 107) lobe-shaped.................... K. wineriterae Burckhardt and Halbert, spec. nov.

3(1). Forewing more rhomboidal; costal margin relatively straight, apical margin more truncate, wing apex lying in anterior half of wing; setae along veins pale but long and conspicuous; surface spinules present throughout most cells. Paramere and aedeagus more slender. Larger species: head width> 0.9 mm, forewing length> 2.8 mm ....................................... K. arcuata Crawford

— Forewing weakly rhomboidal; costal margin more evenly curved, apical margin less truncated, wing apex lying at mid-point of wing; setae along veins shorter and less conspicuous, surface spinules restricted to apices of cells. Paramere and aedeagus relatively shorter and more robust. Smaller species: head width <0.9 mm, forewing length <2.6 mm ................... K. tenuipennis Tuthill
