description: 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, 14) (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) and the absence of complete notauli (Fig. 33). Macropterous females of N. sexramosus have the postmarginal vein about 1.1× the length of the stigmal vein (Fig. 7), 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, 19, 27, 43) or with a terminal, setose, spiniform projection (Figs 31, 59, 68, 83). 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). Males of N. kansensis likely also have a ramose flagellum (but see further below).
