Notanisus Walker, 1837 

Synonymy. See Gibson (2003) or Noyes (2014). Graham (1969: 37) provided features in a key to differentiate both sexes of Pannoniella  from Notanisus  , but Bouček (1991: 204) synonymized Pannoniella  and Amarisca  under Notanisus  . Antsingia Risbec (1952)  was synonymized under Notanisus  by Rasplus in Bouček (1991), and Gibson (2003) synonymized Anacallocleonymus Yang (1996)  .

Recognition. Gibson (2003) provided keys to the tribes of Cleonyminae  and the five world genera of Cleonymini— Callocleonymus Masi  , Cleonymus Latreille  , Dasycleonymus Gibson  , Notanisus  and Zolotarewskya Risbec. He  stated that the petiole is at least subquadrate in Notanisus  , but this description is inexact for N. sexramosus  and N. clavatus Bouček  , in which the body of the petiole is distinct and quadrangular but transverse ( Figs 8 View Figure , 14 View Figure ) ( Bouček 1961, fig. 1). The key of Bouček and Rasplus (1991) readily differentiates Notanisus  from the two other genera of Cleonymini in the Palaearctic region, Callocleonymus  and Cleonymus  , though not all species of the genera in other regions. The presence of N. kansensis  in North America also makes correct keying of Notanisus  difficult using Bouček and Heydon (1997). Females will not key correctly through couplet 55 because of their very short postmarginal vein ( Figs 35, 36 View Figure ) and the absence of complete notauli ( Fig. 33 View Figure ). Macropterous females of N. sexramosus  have the postmarginal vein about 1.1× the length of the stigmal vein ( Fig. 7 View Figure ), but because of the absence of complete notauli will also key through the second half of couplet 55 to couplet 154. They will then key to couplet 170 where they will not key further because of the mixture of features listed in each half of the couplet. However, females of Notanisus  are distinguished easily from other keyed genera by the apical funicular being produced into at least a short projection below the base of the clava in combination with the clava either being tapered apically into a curved, somewhat finger-like projection ( Figs 6 View Figure , 19 View Figure , 27 View Figure , 43 View Figure ) or with a terminal, setose, spiniform projection ( Figs 31 View Figure , 59 View Figure , 68 View Figure , 83 View Figure ). If specimens are taken through the first half of couplet 55 to couplet 62, only one feature given, pronotum longer than mesoscutum, differentiates both sexes of Notanisus  from Cleonymus  . A second feature, bare versus setose eyes, differentiates only females of the two genera in North America (but not all world species), whereas the female feature given is valid only for brachypterous females of N. sexramosus  . Males of N. sexramosus  are distinguished by their ramose flagellum, the basal six funiculars being anelliform but each with an extremely long ramus ( Fig. 10 View Figure ). Males of N. kansensis  likely also have a ramose flagellum (but see further below).
