Hylobothynus obesus Ohaus, 1910

( Figs. 45 – 47 )

Hylobothynus obesus Ohaus, 1910: 678 .

Diagnosis. Endrödi (1985) differentiated Hylobothynus obesus using the basal margin of the pronotum strongly bordered, which is not bordered at its base in H. columbianus . Furthermore, the pygidium of H. obesus is sparsely punctate on the lateral angles, whereas it is more punctate in H. columbianus . The parameres of H. obesus are shorter and wider ( Figs. 46–47 ) than those of H. columbianus ( Figs. 41–42 ).
