Type-species:
Cerambyx octoguttatus
Germar, 1821
(original designation).
Redescription.
Frons short, transverse. Antennal tubercles well-elevated, separated by coronal suture and a deep longitudinally sulcus on each side of suture. Superior lobes of eyes well-separated, distance between them at least twice the width of the upper lobe. Tuberculate between upper lobes (
Fig. 1
), sometimes the tubercle is barely elevated and divided by a suture; gula with transverse sulcus (
Fig. 3
). Antennae filiform, inner face of scape, pedicel, and at least antennomere III–IV with long erect hairs.
Prothorax with two lateral projections, an antemedian tubercle and one medially (sometimes reduced to an acute spine). Surface of prothorax, in both sexes, with deep, thick punctures (as
Fig. 1
), except
S. falli
(
Fig. 7
) and
S. ulkei
(Fig. 15), which have fine and shallow punctures or grooved with shallow rugosities. Pronotum with a transverse sulcus at anterior margin; a central elevation and two visible anterolateral tubercles. Mesosternal process lacking tubercle.
Elytra at least three times as long as broad, apices variable: unarmed, with an internal spine or with both margins spined. Apices of tibiae and femora spined or slightly projected.
Remarks.
In the tribe
Eburiini Blanchard, 1845
the presence of tubercle between the upper ocular lobes and the gula with a transverse sulcus is exclusive of the genera
Susuacanga
and
Styliceps
Lacordaire, 1869
.
Susuacanga
differs from
Styliceps
by the pronotal surface with thick, deep punctures, or finely rugose, by the anterior margin of pronotum with no more than one transverse sulcus, and by the mesosternal process without a tubercle. In
Styliceps
the pronotal surface is very rugose (
Fig. 2
), the anterior margin of pronotum has two transverse sulcus (
Fig. 2
) and the mesosternal process has a tubercle. Besides the characteristics shared with
Styliceps
,
Susuacanga
differs from
Eburia
by its deeply punctured pronotal surface which is never present in
Eburia
.
