Diagnosis
Males of P. ophiiulus resemble those of P. strinatii Mauriès, 1974 and P. tocaiensis by having an internal branch shovel-shaped with horizontal plate (Fig. 102D), but differing by a large prefemoral process (Fig. 102B); solenomere rounded, with seminal apophysis thickened and visible apically (Fig. 102D).
Etymology
Name ‘ophiiulus’ is derived from the Greek words ‘ óphis ’ = ‘snake’, plus the suffix ‘ - ulus’. Although unspecified in the original description, the species name evidently refers to the popular Brazilian reference that millipedes resemble snakes (suborder Serpentes).

Descriptive notes
MEASUREMENTS. 59–63 body rings (2–3 apodous + telson). Males: body length 35–45 mm; maximum midbody diameter 2.4–2.5 mm. Females: body length 35–45 mm; maximum midbody diameter 2.3– 3.1 mm.
COLOR. Body color faded, but apparently prozonites brownish, metazonites with a posterior brown band; head, antennae, and legs lighter; collum brown brownish.
HEAD. Antennae short (Fig. 101A), just reaching back to end of ring 5 when extended dorsally; relative antennomere lengths 1<2<3>4=5=6>7. Mandibular cardo with ventral margin swollen. Ommatidial cluster well-developed, elliptical; ca 25 ommatidia in 5 rows.
BODY RINGS. Collum with lateral lobes broadly rounded, with ca 7 striae, slightly curved ectad (Fig. 101A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 171B).
FIRST LEG-PAIR OF MALES. Coxae (cx) elongated (as long as the sum of remaining podomere lengths), subtriangular, with the base slightly arched and expanded, densely setose (Fig. 102A); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along in its entire extension (Fig. 102B); remaining podomeres with setae along the mesal region.
SECOND LEG-PAIR OF MALES. Coxa (cx) large and subrectangular; penis (pn) located at proximal region, rounded, not extended basally (Fig. 102C); prefemur compressed dorsoventrally; remaining podomeres setose.
GONOPODS. Gonocoxa (gcx) subtriangular, basally expanded and progressively less wide, with the base slightly arched; antero-posteriorly strongly flattened, longitudinal thickened ridge with rows of papillae mesally (Fig. 102D–F). Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder absent. Telopodite (tp) almost as wide as gcx (Fig. 102D); solenomere (sl) with apicomesal process (amp) short; ectal process (ep) short, rounded, separating from amp by shallow notch; sa located at mesal portion, thickened apically. Internal branch (ib) shovel-shaped, with horizontal plate; setae restricted to the apical region of ib exceeding seminal region of sl (Fig. 102D–F).
VULVAE. As typical for the genus. Bursa subtriangular, glabrous (Figs 178F, 210D); internal valve subtriangular, with its sides having the same length; operculum slightly expanded apically; external valve large in oral view, subtriangular.
Distribution
Known from the central region of São Paulo State, Brazil (Fig. 185); occurring in the Cerrado biome (tropical savanna ecoregion) and in second-growth forests in the region.
