Diagnosis. Relatively large species (size close to

D. humeralis ). Antennae longer than D.

lacordairei but shorter than D. humeralis Map C. Distribution map in French Guiana (from Guitet (antennomere X surpassing elytral apex). Elytra et al. 2013) of Deltosoma fernandezi sp. nov.

clearly enlarged towards apex and with sinuous sides, apex flattened and edges raised. Deep black integument with dark blue reflections. Longitudinal stripe across pronotum thinner, humeral maculae very narrowed, with no discal extension. Transverse band whitish, with limits more regular. Legs completely black, except base of femora.

Description. Male ( Fig. 7, 9 , 12 ). Head completely black, with golden setae on clypeus. Coronal suture bordered with few golden setae. Underside of mandibles black. Palpi dark-brown with lighter apex. Mentum, submentum and most part of gula dark-brown. Antennae surpass elytral apex by two segments, totally black. Dorsal sulcus on segments III to VI discreet, softly carinate. Antennomere III longest. Antennomere VIII shortened. Antennal formula based on scape: I = 1.0; II = 0.2; III = 1.4; IV = 1.1; V = 1.2; VI = 1.3; VII = 1.3; VIII= 1.2; IX= 1.3; X= 1.2; XI= 1.6. Antennomere XI curved at distal third.

Prothorax transverse (width/length = 1.7), nearly black. Pronotum bordered with orangish. Sagittal stripe orangish and interrupted before middle; posterior half with small carinae covered with whitish setae; sexual punctation deep on lateral parts of disc; sexual setation orange on lateral margins. Scutellum subquadrate, apex rounded, brown, with yellowish setae on basal half.

Elytra moderately elongate (length/humeral width = 2.5), distinctly enlarged toward apex (maximum width/humeral width = 1.8), with sinuous sides; color deep black with dark-blue reflections; humeral macula very thin, limited to the border; depressed carinae discreet; transverse band whitish, its limits regular, especially on anterior side; apex slightly elevated.

Legs black except trochanters orangish; protibiae moderately curved, enlarged at apex; mesotibiae moderately curved; metatibiae slightly curved. Underside most dark-brown, with denser golden setation, especially on sides. Prosternal process trun-cate with dense golden setae at apex; mesosternal process widely notched.

Aedeagus ( Fig. 12 ). Median lobe short and large, apex rounded. Parameres with rectangular unique tubercle, apex truncate with divergent setae of diverse length.

Female ( Fig. 8 ). Robust (Prothoracic width/length = 1.9). Antennomeres broader and shorter, barely reaching elytral last fifth. Prothorax slightly more triangular, less rounded on lateral sides.

Dimensions in mm (male/female): total length, 16.5-19.1/16.8-21.4; width at humeri, 4.9-5.3/5.0-6.3

Phenology (graph1). Species active during the rainy season (December – July), with 36% of data during March. Kolmorogov-Smirnov test shows a great difference of repartition during year compared to the two previous species (D= 0.78, p= 0.0001).

Chorology (distribution Map C). Rare species mostly found in high hills or mountain areas.

Etymology. This species is dedicated to Serge Fernandez, specialist of Riodinidae (Lepidoptera) , for his contribution to the knowledge of Neotropical Cerambycidae .
