A reassessment of the Neotropical genus Pseudonannolene Silvestri, 1895: cladistic analysis, biogeography, and taxonomic review (Spirostreptida: Pseudonannolenidae) Iniesta, Luiz Felipe Moretti Bouzan, Rodrigo Salvador Brescovit, Antonio Domingos European Journal of Taxonomy 2023 2023-04-27 867 1 1 312 105b90de-558b-45a7-95f8-44b42dc7d431 Iniesta & Bouzan & Brescovit, 2023 Iniesta & Bouzan & Brescovit 2023 [580,910,1025,1052] Diplopoda Pseudonannolenidae Pseudonannolene Animalia Spirostreptida 105 106 Arthropoda species insularis sp. nov.   Figs 155– 156, 164N, 166R, 174D, 179H, 191    Diagnosis Males of  P. insularis sp. nov.resemble those of  P. halophila,  P. maritima,  P. patagonica, and  P. sebastianusby having large and subrectangular coxae on the first leg-pair ( Fig. 156A) and suboval penis ( Fig. 156C), but differing by having the internal branch with horizontal plate; solenomere with apicomesal process and seminal apophysis elongated ( Fig. 156D).    Etymology The species epithet is derived from the Latin adjective ‘  insularis’; in reference to the insular distribution of the species.    Material examined    Holotype BRAZIL• ♂; São Paulo, Ubatuba, Ilha Prumirim; [ -23.385245, -44.944144];  75 ma.s.l.;  2–10 Sep. 1994; C.F.

Males: body length 71.8 mm; maximum midbody diameter 4.9 mm. Females: body length 70.4–79.5 mm; maximum midbody diameter 3.9–5.4 mm.  COLOR. Body color brownish grey; head, antennae, and collum darker; prozonites anteriorly greyish; metazonites with a medial band darker and a posterior lighter; legs brownish.  HEAD. Antennae short ( Fig. 164N), 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 30 ommatidia in 4 rows.  BODY RINGS. Collum with lateral lobes rounded, with ca 10 striae, curved ectad posteriorly ( Fig. 155A). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae up to ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae ( Fig. 174D).  FIRST LEG-PAIR OF MALES. Coxae ( cx) elongated (as long as the sum of remaining podomere lengths), subrectangular, with the base slightly arched, sparsely setose ( Fig. 156A); prefemoral process ( prf) as long as half of prefemur, subcylindrical, densely setose along the entire ventral region ( Fig. 156B); remaining podomeres with setae along the mesal region.  SECOND LEG-PAIR OF MALES. Coxa ( cx) as long as the sum of remaining podomere lengths, subrectangular; penis ( pn) located at proximal region, rounded, extended basally ( Fig. 156C); prefemur compressed dorsoventrally; remaining podomeres setose.  GONOPODS. Gonocoxa ( gcx) elongated, almost twice as long as telopodite, expanded medially, with the base not arched; antero-posteriorly strongly flattened ( Fig. 156D–F); with rows of papillae mesally. Seminal groove ( sg) curved; slightly protruded on squamous region of sl, arising medially on mesal cavity and terminating apically on the seminal apophysis ( sa). Shoulder ( sh) inconspicuous. Telopodite ( tp) almost as wide as gcx( Fig. 156D); solenomere ( sl) with squamous region expanded laterally and folded apically; apicomesal process ( amp) elongated, subtriangular; ectal process absent; salocated at mesal portion, elongated, thickened apically on squamous region. Internal branch ( ib) shovel-shaped and rounded apically, with large horizontal plate, rounded; setae restricted to the apical region of ibexceeding seminal region of sl( Fig. 156D–F).  VULVAE. As typical for the genus. Bursa subtriangular, glabrous ( Fig. 179H); internal valve subtriangular, slightly rounded; operculum narrow; external valve subtriangular, covering operculum basally.    Distribution Known only from the typelocality Ilha Prumirim, Ubatuba, São Paulo State, Brazil( Fig. 191). 4101310280 1994-09-02 1994-09-10 1994-09-02 IBSP C.
