Description of genitalia and associate structures.
Male genitalia (
Figs. 68
─72): median lobe of aedeagus (
Figs. 68, 69
) arcuate, slender, about 3 times as long as wide, largest width near basal fifth, sides subparallel in the basal 4/5 and then gradually converging to rounded anterior margin, asetose; apodemes about as long as median lobe; internal sac with mictrotrichiae but without large sclerites. Tegmen (
Fig. 70, 71
) apex of manubrium (or apodeme) bisinuate. Sternite IX (
Fig. 72
) with spiculum gastrale broad, evenly curved.
Female genitalia (
Figs. 73
─76) Sternite VIII (
Fig. 76
) Y-shaped, apodeme about as long as apical lobe, apodeme apex expanded and globose. Coxites short (
Fig. 74
), about 0.2 times as long as wide; styli cylindrical, setose, elongate, about 1.9 times as long as wide, articulated preapically; spermatheca (
Fig. 75
) with capsule well sclerotized, sickle-shaped, apex unciform, branches of similar size, gland lobe (ramus) about 2 times as long as duct lobe (collum), approximate from each other by distance about as equal as length of gland lobe, gland of spermatheca rounded. Bursa copulatrix without sclerites.

Remarks.
Heilipus gibbus
sp. nov.
is very similar to
H. catagraphus
in appearance. Both share a similar pattern of coloration (
Figs. 1, 2, 7
─10 and 35, 36, 41, 42) and may be confused.
Heilipus gibbus
has been misidentified in collections and literature as
H. catagraphus
,
most likely due to color resemblance. However, the two species can be easily distinguished by the following characteristics (characters of
H. catagraphus
given parenthetically). Base of rostrum strongly gibbous (
Figs. 4
,
12
) (dorsum of rostrum regularly curved from apex to base, not gibbous) (
Figs. 38
,
44
); it is noteworthy that a humped rostrum is not mentioned in the original description of
H. catagraphus
and in any other original description of the
Heilipus
species which occurs in
Brazil
. Tooth of profemur with inner edge rounded (
Figs. 5
,
13
) (inner edge straight,
Figs. 39
,
45
). Basal 2/3 of pronotal disk concave (
Figs. 1, 7
,
9
) (2/3 of pronotal disk flattened,
Figs. 35
,
41
).
Heilipus rufipes
(
Figs. 56, 57
,
62, 63
) is easily distinguished from
H. catagraphus
(
Figs. 35, 36
,
41, 42
) and
H. gibbus
(
Figs. 1, 2, 7,8
,
9, 10
) by the elytral color pattern, formed by an irregular and interrupted band of white scales on each elytral side and isolated patches of similar scales on disc. Other striking differences are the pronotum with rounded tubercles (
Figs. 56
,
62
), the legs evenly dark reddish-brown (
Figs. 56, 57
,
62, 63
), the sternite VIII Y-shaped, with a long strut (
Fig.76
), and different spermatheca with unciform apex (
Fig. 75
).

The stridulatory apparatus in
H. gibbus
sp. nov.
is very similar to that described for
H. odoratus
