Pseudonannolene curtipes Jeekel 2004: 89 Diagnosis Males of P. curtipes resemble those of P. microzoporus , P. caatinga , and P. leopoldoi by having gonopod with subtriangular internal branch, and solenomere with ectal and apicomesal processes ( Fig. 65D ). Pseudonannolene curtipes can be distinguished from those species by having internal branch deeply notched separating from gonocoxa ( Fig. 65D–F ), and a circle-shaped penis ( Fig. 65C ). Etymology Named after the Latin adjective ‘ curtus ’ = ‘shortened’, and the masculine noun ‘ pes ’ = ‘foot’. Unspecified in the original description, but likely to be related either with short coxae of the first leg pair of males or the size of midbody legs.

Descriptive notes MEASUREMENTS . 61 body rings (2 apodous + telson). Males: body length 52–55 mm ; maximum midbody diameter 3–3.5 mm . Females: body length 50–55 mm ; maximum midbody diameter 3.3–3.5 mm . COLOR . Body color brownish grey; head, collum, antennae and legs darker brown; prozonites greyish anteriorly; metazonites with a medial brown band and a posterior reddish band. HEAD . Antennae long ( Fig. 64A ), 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 narrow. Ommatidial cluster well-developed, elliptical; ca 35 ommatidia in 5 rows. BODY RINGS . Collum with lateral lobes rounded, with ca 12 striae, slightly curved ectad ( Fig. 64A ). Very faintly constricted between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae slightly above ozopore in anterior body rings. Anterior sterna in midbody rings subrectangular, without transverse striae ( Fig. 168A ). FIRST LEG-PAIR OF MALES . Coxae ( cx ) short (less than half of remaining podomere lengths), subtriangular, with the base arched, densely setose ( Fig. 65A ); prefemoral process ( prf ) as wide as half of prefemur, subcylindrical, densely setose up to its median region ( Fig. 65B ); remaining podomeres with setae along the mesal region. SECOND LEG-PAIR OF MALES . Coxa ( cx ) broken in paratypes , but large and rounded; penis ( pn ) located at proximal region, circle-shaped ( Fig. 65C ); prefemur compressed dorsoventrally; remaining podomeres setose. GONOPODS . Gonocoxa ( gcx ) elongated, almost twice as long as telopodite, with the base arched; flattened antero-posteriorly ( Fig. 65D–F ); with rows of papillae mesally. Seminal groove ( sg ) curved; arising medially on mesal cavity and terminating apically on the seminal apophysis ( sa ). Shoulder ( sh ) subtriangular. Telopodite ( tp ) almost as wide as gcx ( Fig. 65D ); solenomere ( sl ) with apicomesal process ( amp ) subtriangular; ectal process ( ep ) long, subtriangular, separated from amp by deep notch; sa located at mesal portion, slightly visible apically. Internal branch ( ib ) subtriangular, narrow, slightly curved ectad at midlength, surrounding base of tp as a shield; separated from gcx after deep constriction mesally; with torsion of 180° in the distal portion and a short, rounded projection, directed ectad; ib with setae along its entire margin slightly exceeding apically seminal region of sl ( Fig. 65D–F ). VULVAE . Not examined. Distribution Known only from the type locality Sítio d’Abadia, Goiás State , Brazil ( Fig. 182 ).
