Waynokiops , new genus

( Figs. 1–13 )

Type species. Waynokiops dentatogriphus , new species.

Description. Nymph. Head: Frontal suture angle acute ( Fig. 1 ). Mandibles with incisors cleft to base. Maxillary palp elongate and setose. Labial palp segment 3 with apicolateral corner produced. Thorax: Tarsal claw length subequal to length of respective tarus. Abdomen: Segments 1–7 expanded laterally; anterior terga with protrusions on posterior margins. Gills 1–7 bilamellate and somewhat rounded. Median filament with lateral setal fringes continuous throughout length. Cerci with medial setal fringe continuous throughout length.

Adults. Unknown.

Etymology. The new genus name refers to Lake Waynoka ( U.S.A., Ohio, Brown County), one of the locales (but not the type locale) from which the species has been collected. The suffix “– iops ” is from Greek, meaning small fish, a reference to the small minnow mayflies (family Baetidae ).
