H. balteatus
(

A–D)
Diagnosis.
Pronotum with posterior stripe smoky brown to black in which punctures are black, sometimes punctures on dark small spots (
Fig. 17A
); punctures of the pronotal disc smaller and lighter than those from posterior part. Anterolateral margin of pronotum yellow. Anterior half of scutellum with punctures large, sparse, on dark spots (
Fig. 17A
). Connexivum uniformly green, without dark spots, (
Fig. 17A
). Meso and metapleuron with a pair of faded brown to black rounded spots on base of each coxae (
Fig. 17B
). Apex of pseudosutures of abdomen with black to brown rounded spots (
Fig. 17B
), sometimes these spots are faded due to preservation problems.

FIGURE 21.
Distributional map of the species of
H. quadriden
s
group.
This group can be easily identified inside
Hypoxys
by the smoky brown stripe on posterior part of pronotum always present and associated with punctures clearly darker than those from pronotal disc. In
H. quadriden
s
group this stripe is always solid black and in
H. triangularis
group it is typically absent, except in
H. triangularis
. Punctures on the anterior part of scutellum clearly larger than those on the posterior part and placed in dark spots separates
H. balteatus
group from
H. triangularis
and
H. oxyacanthus
group. Also,
H. balteatus
group never has transversal dark stripes on intersegmental areas of ventral surface, which is enough to separate from
H. quadriden
s
group that always have these stripes.
This group is composed by
H. balteatus
and about 15 new species (description in preparation).
