N: 1
(5) F: 3; {F: 3,00}
Rem.: After A. Scott (1909, p.53) the species is easily recognised by its very swollen one-pointed rostrum, and by the complete segmentation of the 4th and 5th thoracic segments.For Vervoort, this species would belong to the genus Aetideopsis. ? Probably Aetideopsis crassirostris
