Type Species

Decatelia lema Weise.

Diagnosis

Decatelia 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
• 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, finely margined, without lateral teeth
• the apex of the elytra without a tooth-like projection
• the elytra with 10 rows of punctures at base and 4 regular costae, humerus rounded without spine or tooth
• the antennae thickened at apex, with 9- or 10-antennomeres
• leg with apical tarsomere bearing 2 claws, mesotibia curved
• anterior margin of prosternumprosternum:
  contains two anterior coxal cavities
  not expanding toward mouth

Description

Body small; rounded in front; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
large.

Head: clypeusclypeus:
usually quadrangular, elongate; joined to the labrum
triangular, overlapping labrumlabrum:
triangular, joined to the clypeus and the oral orifice
.

Antenna: reaching humerus, filiform, with 9‑ or 10‑antennomeres; antennomere 2 longer than 1; 3 not significantly longer than 2; apical 5 antennomeres thicker and wider than preceding ones.

Pronotum: slightly wider than long, cylindrical; transverse sulcus present before base; lateral margin constricted before base.

Scutellum: transverse, quadrate.

Elytron: wider than 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
at humerus, almost parallel-sided; apex widely conjointly rounded; truncate at base; with 10 rows of punctures plus scutellar row; rows 5 to 8 in a longitudinal cavity with angular sides; rows before cavity confused or reduced to 2 or 3 rows.

Venter: abdominal sterna 1 and 2 separated by deep suture; prosternumprosternum:
contains two anterior coxal cavities
simple, truncate behind.

Leg: mesotibia curved; tarsal claws moderately divergent.
