Justification of synonymy

Having studied the original descriptions, closely examined the type species of P. ambuatinga and P. saguassu and topotypes from caves in the Arcos-Pains-Doresópolis speleological unit, the species P. saguassu and P. canastra are here treated as junior synonyms of P. ambuatinga , according to the similarities in gonopod structure (telopodite and internal branch) and first leg-pair of males. Regarding the species P. canastra , the males described correspond to immatures due to the prefemoral process of first leg-pair being still incipient, short and with few and scattered setae ( Gallo & Bichuette 2020: 37, fig. 3d–e), and the gonopod not fully developed, mainly the internal branch and gonocoxa ( Gallo & Bichuette 2020: 37, fig. 6a–d) (see previous sections for more details on gonopod morphology and ontogeny in Pseudonannolene ).

Diagnosis

Resembling P. lundi and P. spelaea by having head, trunk, and legs depigmented ( Fig. 46 View Fig ). Males of P. ambuatinga differ from P. lundi by having a subtriangular solenomere ( Fig. 47D View Fig ) instead of a square-shaped square-shaped solenomere, and from P. spelaea by having seminal apophysis evident and by the number of ommatidia (ca 25) ( Fig. 46A View Fig ).

Etymology

A combination of words of the Brazilian Indian language Tupi-Guarani, ‘ ambus ’ = ‘millipede’, and ‘ tinga ’ = ‘white’, referring to the body depigmentation of the species ( Iniesta & Ferreira 2013b).

Descriptive notes

MEASUREMENTS. 58–60 body rings (1–2 apodous + telson). Males: body length 35–42.5 mm; maximum midbody diameter 1.8–1.9 mm. Females: body length 36–41 mm; maximum midbody diameter 2–3.1 mm.

COLOR. Living specimens depigmented. Color when stored in 70% ethanol: uniform pale brownish whitish, slightly darker posteriorly on prozonites; head, collum, antennae, and legs light brown.

HEAD. Antennae short ( Fig. 46A View Fig ), 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 23 ommatidia in 4 rows.

BODY RINGS. Collum with lateral lobes broadly rounded, with ca 10 striae ( Fig. 46A View Fig ). 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. 167B 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, densely setose ( Fig. 47A View Fig ); prefemoral process (prf) as wide as half of prefemur, subcylindrical, densely setose along in its entire extension ( Fig. 47B 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, rounded, not extended basally ( Fig. 47C View Fig ); prefemur compressed dorsoventrally; remaining podomeres setose, with long setae mesally.

GONOPODS. Gonocoxa (gcx) elongated, but less than twice the length of the telopodite, with the base slightly arched; slightly flattened antero-posteriorly ( Fig. 47D–F View Fig ); with rows of papillae mesally. Seminal groove (sg) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis (sa). Shoulder (sh) inconspicuous. Telopodite (tp) less than half as wide as gcx ( Fig. 47D View Fig ); solenomere (sl) with apicomesal process (amp) subtriangular; ectal process absent; sa located at medial portion, 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. 47D–F View Fig ).

VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 177C View Fig ); internal valve subtriangular; operculum narrow, not curved medially; external valve wide, subtriangular.

Distribution

A troglomorphic species known only from caves in the Karst region of Pains and surrounding municipalities (Arcos-Pains-Doresópolis speleological unit), state of Minas Gerais, Brazil ( Fig. 180 View Fig ). This karst, which comprises the highest density of caves known for South America, harbors many other undescribed and described cave-dwelling species ( Álvares & Ferreira 2002; Parizotto et al. 2017; Gallão & Bichuette 2018; Pellegrini et al. 2020).

Comments

Although the examination of the type material of the junior synonym P. canastra deposited at the Laboratório de Estudos Subterrâneos (LES/UFSCar) was not possible during this study, the original description and figures provided by Gallo & Bichuette (2020) are highly detailed.
