Description of genitalia and associate structures. Male genitalia ( Figs. 68 View FIGURES 68 – 72 ─72): median lobe of aedeagus ( Figs. 68, 69 View FIGURES 68 – 72 ) 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 View FIGURES 68 – 72 ) apex of manubrium (or apodeme) bisinuate. Sternite IX ( Fig. 72 View FIGURES 68 – 72 ) with spiculum gastrale broad, evenly curved.

Female genitalia ( Figs. 73 View FIGURES 73 – 76 ─76) Sternite VIII ( Fig. 76 View FIGURES 73 – 76 ) Y-shaped, apodeme about as long as apical lobe, apodeme apex expanded and globose. Coxites short ( Fig. 74 View FIGURES 73 – 76 ), 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 View FIGURES 73 – 76 ) 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 View FIGURES 1 – 8 ─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 View FIGURES 1 – 8 , 12 View FIGURES 9 – 14 ) (dorsum of rostrum regularly curved from apex to base, not gibbous) ( Figs. 38 View FIGURES 35 – 40 , 44 View FIGURES 41 – 46 ); 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 View FIGURES 1 – 8 , 13 View FIGURES 9 – 14 ) (inner edge straight, Figs. 39 View FIGURES 35 – 40 , 45 View FIGURES 41 – 46 ). Basal 2/3 of pronotal disk concave ( Figs. 1, 7 View FIGURES 1 – 8 , 9 View FIGURES 9 – 14 ) (2/3 of pronotal disk flattened, Figs. 35 View FIGURES 35 – 40 , 41 View FIGURES 41 – 46 ).

Heilipus rufipes ( Figs. 56, 57 View FIGURES 56 – 61 , 62, 63 View FIGURES 62 – 67 ) is easily distinguished from H. catagraphus ( Figs. 35, 36 View FIGURES 35 – 40 , 41, 42 View FIGURES 41 – 46 ) and H. gibbus ( Figs. 1, 2, 7,8 View FIGURES 1 – 8 , 9, 10 View FIGURES 9 – 14 ) 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 View FIGURES 56 – 61 , 62 View FIGURES 62 – 67 ), the legs evenly dark reddish-brown ( Figs. 56, 57 View FIGURES 56 – 61 , 62, 63 View FIGURES 62 – 67 ), the sternite VIII Y-shaped, with a long strut ( Fig.76 View FIGURES 73 – 76 ), and different spermatheca with unciform apex ( Fig. 75 View FIGURES 73 – 76 ).
