Synonomys

None.

Type Species

Spaethaspis lloydi Hincks.

Diagnosis

Spaethaspis 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; mouthparts not projecting forward, interantennal carina not distinct
• 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, sides almost parallel
• the apex of the elytra without a tooth-like projection
• the elytra without costae, rounded, posterior margin smooth
• the antennae with 11-antennomeres, filiform, antennomeres 1 and 2 elongate

Description

Body elongate; 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
rectangular with sides almost parallel.

Head: vertexvertex:
occupies the area behind and between the eyes
finely and sparsely punctate, deeply impressed; interocular space broad, flat; interantennal carina absent; clypeusclypeus:
usually quadrangular, elongate; joined to the labrum
very short, nearly 4x as wide as long; maxillary palp with palpomere 4 subequal in length to 3.

Antenna: with 11-antennomeres; basal two antennomeres glabrous; remaining antennomeres feebly pubescent; antennomere 2 ½ length of 1 or 3; 4 subequal in length to 3.

Pronotum: transverse; anterior margin deeply emarginate in middle; lateral margin straight for basal 2/3s, then slightly converging towards apex; anterior angle broadly rounded; basal margin prominent and more or less truncate adjacent to scutellumscutellum:
sclerotized portion of the mesonotum, visible between elytral bases; usually more or less triangular, pentagonal, or quadrate
, slightly oblique on either side to angulate posterior angle; posterior angle with shallow depression; sparsely, finely punctate on disc, strongly, distinctly punctate at sides.

Scutellum: broadly triangular.

Elytron: moderately wide, almost 2x as long as wide; transverse impression behind humerus; lateral margin expanded, somewhat concave with polished margin, slightly widened behind, broadly rounded at apex; with 10 rows of fine punctures plus scutellar row; intervals wide.

Venter: prosternumprosternum:
contains two anterior coxal cavities
broad, strongly expanded behind with deep longitudinal grooves, middle groove longest and widest; abdominal sternites flat, very finely punctate, apical segment more or less truncate, without apical emargination.

Leg: tarsal claws with large basal tooth.

Distribution

Ecuador, Peru.
