by monotypy.
Redescription.
Body oval, convex (
Figs. 1, 2
). Eyes finely faceted and glabrous, emarginate near antennal insertions (
Fig. 3
). Antennal insertions visible. Antennae short, composed of eleven antennomeres; scape twice as long as wide; with slight lateral lobe; pedicel quadrangular; antennomeres 3–8 slender, 9–10 longer; 11 conical (
Fig. 4
). Clypeus with apical margin arcuate and lateral margins rounded, short and projected (
Fig. 3
). Labrum rectangular in shape (
Fig. 5
). Mandible asymmetrical, large and robust, strongly sclerotized; with incisor teeth, apical and subapical, with pointed median molar (
Fig. 6
). Maxillae sclerotized; palpomere 4 securiform with sides that diverge strongly (
Fig. 7
). Labium having anterior margin of ligula densely covered with small spines, having ventral median portion of ligula with several long bristles; each labial palp with basal articles shorter, and the last narrower in the distal region. Mentum

cordiform, with rounded apical projections; prementum truncate, with long bristles in median region between palps (

). Pronotum transverse; prosternal carinae convergent and finishing together at base of prosternum; prosternal process with nearly parallel sides (

very shallow V-shaped anterior border, with anterior arms nearly straight apically (
Fig. 10
). Wings with reduced alar venation; first and second anal veins and Ea, Eb and P evident (
Fig. 11
). Elytra oval with raised humeral callosity and with lateral margin not flattened (
Figs. 1, 2
); epipleuron with strong excavation to receive apex of medium and posterior femur (
Fig. 12
). Femur robust and deeply excavated to receive tibia. Anterior tibia thin and strongly excavated to receive tarsus (
Fig. 13
). Second tarsomere triangular in ventral view; tarsal claw appendiculate (
Fig. 14
). Abdomen with 278 incomplete post-coxal lines on the first visible sternite; seven visible segments present in the male, six in the female (
Figs. 15, 16
). Male genitalia: Median lobe asymmetrical, parameres longer than median lobe. Sipho strongly sclerotized, curved. Female genitalia: Spermatheca alantoid; infundibulum present; coxites wide with slender bristles, without stylus.

Type Material.

lectotype
and
paratype

) were studied, and are located at the

Remarks.
The genus
Tiphysa
was included in the tribe
Hyperaspini
(
¼
Hyperaspidini
) by
Duverger (1989)
because of the rounded spermatheca and absence of infundibulum, but it was a mistake. We transferred here
Tiphysa
to Brachiacanthini, together with
Brachiacantha
Chevrolat
in
Dejean, 1837,
Hinda
Mulsant, 1850
and
Cyra
Mulsant, 1850
.
Tiphysa
together with the other genera of Brachiacanthini, has integument glabrous; eyes emarginate near antennal insertions; eleven antennomeres; 4° maxillary palpomere securiform; 2° tarsomere triangular; six abdominal segments visible on female and seven in male; spermatheca alantoid and infundibulum present. It differs from
Brachiacantha
by presence of a sharp spine on
Figs. 21–22.

anterior tibia; and from
Hinda
by the strongly serrated anterior border of tibia (Almeida and Milléo 1999) and from
Cyra
by the thin unornamented tibia without ornamentation (
Milléo
et al.
1997
).
Tiphysa
is similar to
Thalassa
Mulsant, 1850
of the tribe
Hyperaspidini
, in both color and size, but differs from
Thalassa
in the more rounded body; the absence of emargination of the eyes; shape of anterior tibia; male and female with six abdominal segments; spermatheca globular and absence of infundibulum.
