Type Species

Drescheria reinecki Weise.

Diagnosis

Drescheria can be distinguished by the following combination of characters:

• lateral margin of pronotumpronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  and elytra without long, stiff spines
• head with frontal horn which is as long as wide between antennae
• antennae thickening apically, antennomere 1 without spine-like process
• pronotum pronotum:
  occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
  with lateral margin straight for basal ½, expanding and rounding anteriorly
• elytra with 8 rows of punctures plus scutellar row, tricostate
