Diagnosis. Roeweria can be distinguished from most other genera of Pachylinae by the penis with ventral plate cordiform or hexagonal (rectangular or pyriform in most other genera) and stylus with two lateral apical projections ( Figs. 5 , 6 , 8 ). The shape of the external apophysis of coxa IV is unique among Pachylinae , as it is unbranched, long and curved downwards, following the orientation of the external margin of trochanter IV. Femur IV is straight ( Fig. 7 A–D) or slightly arched dorsad ( Fig. 3 E). Other characters can be used in combination to distinguish this genus from other Pachylinae genera: ocularium and area III with a large pair of apophyses ( Figs. 1 , 2 , 4 , 7 ); most tubercles of dorsal scutum surrounded by yellow patches ( Fig. 7 ); female free tergites I–III with one central pair of high and acuminated tubercles ( Fig. 2 ); area III with blunt armature; coxa IV with internal apophysis; trochanter IV longer than wide ( Figs. 1 A,C, 4, 7); long and smooth stylus of penis ( Figs. 5 , 6 , 8 ).
