Description. Measurements: male holotype with 42 body rings, circa 31 mm long, 2.4 mm wide.

Coloration almost completely decolorized because of alcohol, light stripe visible dorsally.

Head: each eye with circa 30 ocelli arranged in 5 or 6 vertical rows. Labrum with standard three irregular teeth and a single row of 10–12 stout marginal setae. Clypeus with two setiferous foveolae on each side. Antennal cavity absent. Antennae very long, protruding back to ring 7. Relative lengths of antennomeres: 1<2>3=4=5=6, antennomere 2 longest. Terminal antennomere with four large sensory cones located together inside a membranous area. Antennomere 5 latero-apically four or five rows, antennomere 6 with two or three rows of sensilla basiconica.

Gnathochilarium: lamellae linguales each with two standard setae located behind one another. Stipites each with three apical setae. Mentum basally subdivided by a prominent suture. Mandible not dissected.

Collum: smooth, laterally not protruding as far as ring 2.

Body rings: mostly smooth, with some irregular punctation on mesozona. Ozopores starting at ring 6, touching suture between mesozona and metazona. Ozopore on ring 6 located more ventrally than subsequent ozopores.

Telson: anal valves with weakly developed lips, with neither grooves, nor setae ( Fig. 23A View Figure 23 ). Preanal ring and subanal process well-rounded, not extending beyond anal valves.

Legs: coxae 1 and 2 elongated and fused with sternum, podomeres from prefemur to tarsus in both sexes each with 4–10 ventral/mesal setae. Length of midbody legs as long as body diameter in males. Each podomere with a single or pair of apical, ventral seta(e). Coxae 3 and beyond of cylindrical shape ( Fig. 23B View Figure 23 ). Tarsus with a stout dorsoapical setae and three pairs of setae; apical pair stout, others successively much smaller.

Male sexual characters: tarsal pads absent ( Fig. 23B View Figure 23 ). Coxae 3 and 4 each with a short, conical process. Process protruding posteriorly, but never overlapping adjacent coxa.

Anterior gonopod sternite elongated into a wide, triangular lobe with a well-round- ed tip ( Fig. 23C View Figure 23 ). Mesal process of coxite wide, long and well-rounded, shorter than sternite lobe ( Fig. 23C View Figure 23 ). Process of telopodite large and slender, retrorse part not located apically, but basally of process ( Fig. 23D View Figure 23 ). Retrorse projection slender, short with a well-rounded tip ( Fig. 23D View Figure 23 ). Posterior gonopods unique ( Figs 23E, F View Figure 23 ). Gonopod pair connected via a large, well-sclerotized sternite ( Fig. 23E View Figure 23 ). Telopodites positioned parallel to one another. Coxite and telopodite not separated from one another, but dividing suture well-visible ( Fig. 23E View Figure 23 ). Coxite wide, with a single groove and no appendage ( Fig. 23F View Figure 23 ). Telopodite completely elongated into a process, apically tapering ( Fig. 23F View Figure 23 ), very slender. Sperm canal running along mesal margin of telopodite, apically occupying whole width of joint ( Fig. 23F View Figure 23 ).

Etymology: pauliani , adjective, after the collector Dr. Renaud Paulian (1913– 2003), who collected numerous interesting millipedes on Madagascar.
