( Figs 170–175 )

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

Diagnosis. Face without subantennal sulcus ventral to each torulus and toruli abutting transverse trabecula ( Fig. 170a ); mandibles in female minute, with a wide gap between them when closed, mandibles in male massive, with a long ventrally serrate dorsal tooth, strongly overlapping when closed ( Fig. 171 ); funicle 5- or 6-segmented, with clava 3-segmented; frenum longitudinally divided by median sulcus and paramedial plates about as wide as long ( Fig. 174 ); fore wing with venation greater than half wing length ( Fig. 172 ); ovipositor distinctly exserted beyond apex of gaster. Male flagellum 9-segmented, with junction between apical two segments wide ( Fig. 173 ).

Remarks. Krokella belongs to the Anagrus group of genera. It is one of two genera in the group with venation greater than half the wing length; the other is Neopolynemoidea . Krokella differs in having the fore wing wide, with a somewhat truncated apex ( Fig. 172 ).
