Diagnosis. Adult males differ from all other species of the genus by the following combination of characters: prefemoral process longer than wide, oval; secondary process spatulate, arising from the basal inner margin of the prefemoral process (Fig. 39) and curving upward at approximately 45°; color of body rings dark red to black (Figs 35−37).  
 Description. Male (Holotype, INPA 396). Coloration (preserved in 70% ethanol): head and antennae dark reddish; labrum lighter than the head; 7 th antennomere yellowish; body and paranota tips dark red, nearly black (Figs 35−37); legs reddish brown, lighter than paranota (Fig. 36); telson dark reddish (Fig. 37). Head: with several thin setae; incisura lateralis suboval. Antennae: almost reaching the 5 th body ring; 5 th, 6 th and 7 th antennomere with a grouping of basiconic sensilla in small clusters on the distal and external margin. Body rings: cuticle with several small tubercles scattered across the metazonites; some larger tubercles along the posterior edge region of the metazonites, distributed in two nearly horizontal rows; large tubercles barely noticeable on the last segments (Fig. 37). Sternites with several thin elongate setae; sternite of sixth segment with two pairs of small, acute projections, becoming more conspicuous along the post-gonopodal sternites. Paranota: anterior border rounded; posterior border sub-rectangular (Fig. 35−37); metazonites 6, 8, 11, and 14 with small “tooth” on the posterior border (Fig. 36). Ozopore arrangement: 5, 7, 9, 10, 12, 13, 15–19 (following the typical polydesmidan pore formula); ozopores surrounded by peritremata, positioned medially on paranota; peritremata suboval, projected laterally(Fig. 36). Legs without modifications, except for a conspicuous dorsal lobe on the prefemur. Telson:triangular (Fig. 37); epiproct with (3+3) macrosetae on the dorsal side supported by small projections; two pairs (2+2) of spinnerets, superior pair more closely positioned to each other as compared to the inferior one; paraprocts each with two macrosetae; hypoproct triangular with one pair of macrosetae supported by small triangular projections. Gonopod aperture transversely oval, as typical for the genus, small, with a lateral pair of sclerotized triangular slit to accommodate the gonopods (Fig. 8).   
Total length: 55.30. Total width: 8.13. Antennomere lengths (1−7): 0.68; 1.77; 1.53; 1.38; 1.29; 1.61; 0.31. Podomere lengths (1−7): 0.49; 0.89; 2.34; 0.80; 0.82; 1.44; tarsal claw 0.26. Gonopod aperture: length 0.85, width 1.88. Telson length: 1.07. Gonopod: length 1.65, width 1.74. Gonocoxae: length 0.67, width 1.46. Telopodite: length 1.60, width 0.77. Gonopods: gonocoxae subequal to the length of the telopodite, globose, projected on the ectal side (Fig. 40); with a small spiniform process; two macrosetae present on the dorsal side and two additional macrosetae present on the terminal portion of the ectal side. Prefemoral region ventrally positioned and setose, approximately 1/2 the length of the solenomere (Figs 38, 39). Prefemoral and acropodite regions separated by a cingulum basally (C; Figs 38−40). Prefemoral process (PfP; Fig. 38): longer than wide; longer than the solenomere; containing a thin (Fig. 38) and spatulate (Fig. 39) secondary process on the inner margin of its basal portion. Solenomere falciform, carrying the seminal groove to apical point (S; Figs 38−40).  
Female. Unknown.  
Type material. Holotype: male from Crique Alama (2°13’40.6”N; 54°27’58.1”W), Maripasoula, French Guiana, 08.iii.2015, alt. 595m, V. Vedel leg. (INPA 396).  
Distribution. Known only from Maripasoula, French Guiana (Fig. 53).  
Etymology. The specific epithet is a patronym in honor of Dr. Julián Bueno Villegas for his friendship and outstanding contributions to our knowledge of millipedes.
