Zanthojoppa CAMERON, 1901

T y p e s p e c i e s: Zanthojoppa trilineata CAMERON, 1901 .

According to HEINRICH (1975) this genus can be differentiated from Hoplismenus GRAVENHORST by three features: (1) The scutellum is distinctly narrowed to apex in both sexes; (2) the thyridium is shorter than in Hoplismenus and distinctly separated from the basal margin of 2 nd tergite so that the gastrocoelus is elongate and only slightly impressed; and (3) the body including the metasoma is slenderer than in Hoplismenus . In addition, the apical margin of the hypoypgium of ♁ – at least in the European species – is not elongate medially, but moderately rounded.

This genus otherwise shows the features described for Hoplismenus above. The separation of both genera is accepted here, but for a definite taxonomical analysis of these genera, further studies of the Palaearctic and Oriental faunas as well as additional molecular data will be necessary.
