Synonomys

Mimocthispa Pic (misspelling).

Type Species

Mimoecthispa irregularis Pic.

Diagnosis

Mimoecthispa can be distinguished by the following combination of characters:

• the lateral margins of the 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 the elytra without long, stiff spines
• the head without a frontal horn, fronsfrons:
  upper anterior portion of head capsule above the clypeus
  projecting, vertexvertex:
  occupies the area behind and between the eyes
  without medial sulcus
• the 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
  with a seta in each anterior angle
• the apex of the elytra without a tooth-like projection
• the elytra with 8 rows of punctures at base and 9 apically, with 3 weak costae
• the antennae thickened at apex, not clavate, with 8-antennomeres, antennomere 8 the largest
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth

Description

Oblong‑elongate, somewhat dilated apically, shining.

Head: vertexvertex:
occupies the area behind and between the eyes
micropunctate; medial sulcus absent; fronsfrons:
upper anterior portion of head capsule above the clypeus
with projection at base of antennaantenna:
3 to 11 segments, inserted in antennal pit in front of eyes
; clypeal margin evenly arcuate.

Antenna: with 8‑antennomeres, antennomeres 1 to 6 small; 7 elongate, as long as 4 to 6 combined; 8 largest, 3x length of 7, apex somewhat attenuate.

Pronotum: widest at base, narrowing anteriorly; disc impunctate; basal impression present, with scattered punctures; laterally with dense, large punctures.

Scutellum: triangular; micropunctate.

Elytron: lateral and apical margins dentate; flattened lamina present from exterior apical angle to suture; humerus pronounced; with 8 rows of punctures at base, expanded to 9 rows apically, additional row present between costae 2 and 3; tricostate, costa 3 as wide as a puncture row.
