Diagnosis. Relatively large species. Sides of elytron enlarged toward apex with slightly sinuous sides. Integument lighter than other species.

Antennae longer, segment IX surpassing elytral apex. Pronotum with wide orange margins, black maculae not reaching anterior and posterior margins. Elytra with large humeral maculae with discal extension (sometimes reduced or absent),

transverse band orangish, elytral carinae rather soft. Legs with basal half and apex of femora orange, base of tibiae orange.

Description. Male ( Fig. 4, 6 , 11 ). Coronal suture bordered with orangish setae toward upper interocular space, followed by triangular orangish macula on vertex. Underside of mandibles brown with black apex. Antennae long, surpassing apex by more than two segments; segment VII the longest (XI excepted).Antennomeres III-VI subcylindrical, elongate; antennal sulcus distinct from antennomere III to VI, dorsally with two clear longitudinal carinae on dorsal side. Antennal formula based on scape: I = 1.0; II = 0.2; III = 1.3; IV = 1.2; V = 1.4; VI = 1.5; VII = 1.5; VIII= 1.4; IX = 1.4; X = 1.4; XI = 2.1.

Prothorax transverse (width/length = 1.8); sides rounded, especially at basal two-thirds, with discreet angle at second third of length. Pronotum with lateral black bands large, orange space be- Map B. Distribution map in French Guiana (from Guitet et al. 2013)of Deltosoma humeralis sp. nov. tween them slender, barely enlarge at center of disc, but more distinctly anteriorly and posteriorly. Prosternal process notched at apex. Central part of mesosternum orange, laterally brown. Remain- der of underside brownish, with moderately dense golden setae. Scutellum trapezoidal with rounded apex.

Elytra relatively elongate (length/humeral width = 2.3), enlarged towards apex (maximum width/ humeral width = 1.5); elytral carinae slightly depressed. Humeral macula large, connected to circular pre-sutural macula, slightly surpassing the two longitudinal carinae on their inner and outer limits. Transverse band clearly orangish, distinctly serrate, particularly on its posterior limit. Basal and apical third of femora orangish. Protibiae distinctly curved and enlarged at apex; mesotibiae moderately curved; metatibiae almost rectilinear.Aedeagus ( Fig. 11 ). Median lobe relatively elongate, notched at apex. Parameres with unique tubercle, its sides parallel, with long and parallel setae.

Female ( Fig. 5 ). Robust (Prothoracic width/length = 1.9; elytral width at humeri/length = 2.5). Antennae much shorter than in male, barely reaching distal fifth of elytra. Segments broader. Prothoracic shape more triangular, laterally less rounded.

Dimensions in mm (male/female): total length, 15.5-18.6/13.5-19.8; width at humeri, 4.9-5.9/4.4-6.4.

Phenology (graph 1). Species active in dry season (July – October), with 40% of data in August. Kolmorogov-Smirnov test shows a great similarity of repartition during the year with D. lacordairei (D= 0.07, p= 0.12). As for the previous species, some early outbreaks (March – April) can be awarded to emergence chambers.

Chorology (distribution Map B). Uncommon species largely distributed in French Guiana.

Etymology. The name refers to the developed humeral maculae of this species.
