Diagnosis

Resembling P. ambuatinga and P. spelaea by having head, trunk, and legs depigmented ( Fig. 85 View Fig ). Males of P. lundi differ from P. ambuatinga by square-shaped solenomere ( Fig. 86D View Fig ), and from P. spelaea by having an evident seminal apophysis and a greater number of ommatidia (ca 25) ( Fig. 85A View Fig ).

Etymology

Patronym honoring the Danish naturalist Peter Wilhelm Lund, who is considered the founder of speleology as a science in Brazil. The name also refers to the caving Brazilian group “Espeleo Grupo Peter Lund”, for their contributions to our knowledge of the caves of the region where the species occurs ( Iniesta & Ferreira 2015).

Descriptive notes

MEASUREMENTS. 62–68 body rings (1–2 apodous + telson). Males: body length 49.5 mm; maximum midbody diameter 2.7–2.8 mm. Females: body length 61.9 mm; maximum midbody diameter 2.8–3 mm.

COLOR. Living specimens depigmented. Color when stored in 70% ethanol: uniform pale brownish white, faint dark shadows posteriorly on prozonites; head, collum, antennae, and legs brownish.

HEAD. Antennae long ( Fig. 85A View Fig ), just reaching back to end of ring 6 when extended dorsally; antennomeres elongated; relative antennomere lengths 1<2<3>4>5≈6>7. Mandibular cardo with ventral margin swollen. Ommatidial cluster well-developed, elliptical; ca 30 ommatidia in 5 rows.

BODY RINGS. Collum with lateral lobes rounded, with ca 10 striae, slightly curved ectad ( Fig. 85A View Fig ). Very faint constriction between prozonites and metazonites; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, with shallow transverse striae ( Fig. 170A View Fig ).

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. 86A View Fig ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along its entire extension ( Fig. 86B View Fig ); remaining podomeres with setae along the mesal region.

SECOND LEG-PAIR OF MALES. Coxa (cx) large and subrectangular; penis (pn) located at proximal region, large and rounded, not extended basally ( Fig. 86C View Fig ); prefemur compressed dorsoventrally; remaining podomeres setose.

GONOPODS. Gonocoxa (gcx) rounded, basally expanded and progressively less wide, with the base arched; flattened antero-posteriorly ( Figs 86D–F View Fig , 212B); with rows of papillae mesally. 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. 86D View Fig ); solenomere (sl) with apicomesal process (amp) short, rounded; ectal process (ep) rounded, separated from amp by shallow notch; sa located at mesal portion, slightly visible apically. Internal branch (ib) shovel-shaped and rounded apically, with horizontal plate; setae restricted to the apical region of ib exceeding seminal region of sl ( Fig. 86D–F View Fig ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 177O View Fig ); internal valve subtriangular, strongly inclined towards the mesal region; operculum narrow, constricted medially; external valve wide, subtriangular.

Distribution

A troglomorphic species known only from the type locality Lapa Sem Fim cave, Luislândia, state of Minas Gerais, Brazil ( Fig. 184 View Fig ). The Lapa Sem Fim cave corresponds to the largest cave in the Brazilian state, with at least 15 km of an intricate system of conduits and only two known entrances located in the extremities of the only intermittent drainage.
