KROKELLA Huber, 1993 View in CoL

( Figs 500–518 View FIGURE 500 View FIGURES 501–504 View FIGURES 505, 506 View FIGURES 507–510 View FIGURES 511, 512 View FIGURES 513–518 )

Krokella Huber, 1993: 349 View in CoL . Type species: Krokella fera Huber, 1993 View in CoL , by original designation.

Diagnosis. Body length 385–485 μm. Face without subantennal sulci ( Fig. 501 View FIGURES 501–504 , 513 View FIGURES 513–518 ); clava 3-segmented ( Figs 500 View FIGURE 500 , 504 View FIGURES 501–504 ); mandible a minute stub without teeth ( Figs 501 View FIGURES 501–504 , 513 View FIGURES 513–518 ); ocular apodeme apparently absent but ocular ridge with anterior margin greatly thickened ( Fig. 503b View FIGURES 501–504 ); frenum divided medially by longitudinal sulcus ( Figs 511 View FIGURES 511, 512 , 515 View FIGURES 513–518 ); fore wing with venation extending more than half wing length. Male with mandible enormous, crocodile-like ( Figs 508 View FIGURES 507–510 , 518 View FIGURES 513–518 ); flagellum 9-segmented ( Fig. 509 View FIGURES 507–510 ).

Discussion. Only two other Nearctic genera, Neostethynium and Stethynium , have the clava 3-segmented. Krokella differs from both by having the fore wing venation extending more than half the wing length. It is similar to Neostethynium based on the very similar male mandible, and to Stethynium based on the longitudinally divided frenum.
