None.

Type Species

Sternostenoides daguerrei Monrós & Viana.

Diagnosis

Sternostenoides can be distinguished by the following combination of characters:

  • body slender parallel-sided
  • 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
  • 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, without two blunt teeth on anterior margin
  • the apex of the elytra without a tooth-like projection
  • the elytra with 8 rows of punctures for entire length and 3 regular costae, humerus rounded without spine or tooth
  • the antennae thickened at apex, with 10-antennomeres
  • leg with apical tarsomere bearing 2 claws, mesofemora with tooth
  • anterior margin of prosternumprosternum:
    contains two anterior coxal cavities
    not expanding forward partly covering mouth

Description

Body elongate, subcylindrical.

Head: medial sulcus faint; fronsfrons:
upper anterior portion of head capsule above the clypeus

Antenna: with 10‑antennomeres; antennomeres 1 and 2 similar, wider than the next three; 3 to 5 lengthened; 6 shorter and wider than 5; 8 to 10 thicker than rest, forming a poorly defined club.

Pronotum: narrower than elytra, cylindrical; parallel-sided, slightly elongate; irregularly punctate.

Scutellum: quadrangular.

Elytron: lateral and apical margins finely dentate; apex conjointly rounded; with 8 rows of punctures plus scutellar row; tricostate, united on apical 1/5.

Leg: mesotibia strongly curved; mesofemur with short spine.

Venter: prosternumprosternum:
contains two anterior coxal cavities
with short median plate on anterior margin.
