Pseudonannolene bovei bovei [by implication] – Brölemann 1929: 16.
Diagnosis
Males of P. bovei resemble those of P. anapophysis, P. caulleryi, P. inops, and P. xavieri by having a triangular solenomere, with an ectal process directed horizontally (Fig. 52E), but differing by the short coxae on the first leg-pair not projected apically (Fig. 52A); and a subtriangular internal branch (Fig. 52E).
Etymology
Patronym honoring the Italian explorer Giacomo Bove (Silvestri 1895a).
Material examined
Syntypes
ARGENTINA • 1 ♂ [gonopods, second leg-pair, and gnathochilarium missing; other possible syntypes not found]; Misiones, San Ignacio, Giabibbirri; [-27.256834, -55.540414]; 30 m. a.s.l.; 1884; G. Bove leg.; MCSN.
Descriptive notes
Gonopod description adapted from Silvestri (1895a: 776) to supplement original description and to introduce gonopod terminology; remaining male sexual characters described based on examined syntype and non-sexual described as female.
MEASUREMENTS. 50 body rings (1 apodous + telson). Males: body length ca 50 mm; maximum midbody diameter 3 mm.
COLOR. Body color faded because of long preservation in ethanol, but prozonites appearing brownish, metazonites with a brown posterior band; head, collum, antennae, and legs lighter brown.
HEAD. Antennae short (Fig. 51A), just reaching back to end of ring 5 when extended dorsally; relative antennomere lengths 1<2<3>4>5<6>7. Ommatidial cluster well-developed, covered partially by anterior region of collum; ca 25 ommatidia in 4 rows.
BODY RINGS. Collum with lateral lobes broadly subrectangular, with ca 4 striae, slightly curved ectad posteriorly (Fig. 51A). Very faintly constriction between prozonite and metazonite; prozonites smooth; metazonites laterally with transverse striae below ozopore. Anterior sterna in midbody rings subrectangular, without transverse striae (Fig. 176B).
FIRST LEG-PAIR OF MALES. Coxae (cx) short, subtriangular, with the base arched, densely setose mainly on distal region (Fig. 52A); prefemoral process (prf) short (less than half the length of the prefemur) and slightly constricted basally, subcylindrical, densely setose up to its median region (Fig. 52B).
SECOND LEG-PAIR OF MALES. Not examined.
GONOPODS. Gonocoxa (gcx) elongated, almost twice as long as telopodite, subrectangular; antero-posteriorly flattened; with rows of papillae mesally. Seminal groove (sg) terminating apically on the seminal apophysis (sa). Shoulder (sh) rounded. Telopodite (tp) as wide as half of gcx; solenomere (sl) with apicomesal process (amp) subtriangular; ectal process (ep) subtriangular, elongated and perpendicular to amp. Internal branch (ib) subtriangular, surrounding tp basally as a shield; ib with setae along its entire margin exceeding apically the seminal region of sl (Fig. 52E).
VULVAE. Not examined.
Distribution
Known only from the type locality of Misiones, Argentina (Fig. 181).
