Vilga (Laevivilga) sanctipauli Dolling, 1977: 39 ; Packauskas, 2010: 224.

Holotype male, Brazil, São Paulo, Piracicaba , 22.i.1965, W.E. and C.A. Triplehorn ( OSUC) (examined by photograph).

Material examined. Brazil, Rio Grande do Sul: Porto Alegre, Jardim Botânico, 12.ii.2014, Costa & Lapischies col., rede de varredura, 2 ♀ ( MCNZ 182413 , MCNZ 182415 ) ; idem, 12.iii.2014, ♀ (MCNZ 182414); idem, 09.v.2016, Schmitz & Dutra col., ♀ (MCNZ 182416); idem, 09.v.2017, Costa col., ♂ (MCNZ 182418); Triunfo, Parque COPESUL, 12.xi.2007, C. Ohlveiler col., rede de varredura, ♀ (MCNZ 180302); Montenegro , 03.xi.1977, M. H. Gallileo col. ♀ ( MCNZ 10764 ) ; Salvador do Sul, 05.xii.1993, A. Specht. col., ♂ ( MCTP 2788 ) .

Diagnosis. Mandibular plates lacking ventral spines. Corium with few setae. Pro- and mesofemora with a single ventral spine. Spermathecal bulb rounded apically. Ejaculatory reservoir complex without thickenings. Vesica shorter than phallotheca.

Description. Color pattern ( Figs. 15–16 ). General color castaneous to reddish castaneous. Antennal segment IV darker than I –III. Rostral segment IV apically darker than remaining segments. Femora dark castaneous, with basal yellowish areas variable in extent, more frequent in hind femora. Tibiae mostly yellowish, with proximal and distal ends dark castaneous. Corium, in some specimens, with piceous apical spot near M and R veins. Connexivum segments with irregular piceous transverse stripes along anterior and posterior margins. Urosternites with two longitudinal darker areas variable in extent.

Head. Dorsal surface with small tubercles as described for V. (L.) antennata sp. nov. Mandibular plates and tylus equal in length, surpassing antennifers. Antennal segment II with less than half the width of segment I. Mandibular plates and tylus equal in length, surpassing antennifers. Bucculae smooth, at least half as long as first rostral segment. Ventral surface of head longitudinally sulcate. Remaining characters as described by Dolling (1977).

Thorax. Pronotum, scutellum and hemelytra less pubescent than V. (L.) antennata sp. nov. and V. (L.) brasiliensis . Pleura punctate. All thoracic sterna sulcate. Ostiole, in ventral view, located innerly to imaginary longitudinal line along outer margin of metacoxae. Remaining characters as described by Dolling (1977).

Abdomen. Urotergites II–VI irregularly punctate. Tergo-connexival suture ( Rueda 1992) on urotergites II–VI. Urosternite III with two sublateral depressions. Remaining characters as described by Dolling (1977).

Male genitalia ( Figs. 17–21 ). Pygophore globose ( Figs. 18 ). Posterolateral angles rounded ( Figs. 18–19 ). Ventral rim, in posterior view, convex in middle ( Fig. 17 ). Apex of paramere truncate ( Fig. 21 ); spine much shorter than half width of paramere at the same level. Ejaculatory reservoir complex without thickenings ( Fig. 20 ). Vesica shorter than phallotheca ( Fig. 20 ).

Male measurements (mm). Total length 7.2; antennal segments: I—0.8, II—0.9, III—1.2, IV—0.8; head length 1.3, width 1.1; interocular distance 0.7; interocellar distance 0.2; anteocular region 0.6; rostral segments: I—0.9, II—0.9, III—0.4, IV—0.6; pronotum length 1.4, width 2.6. Scutellum damaged by the pin.

Female genitalia ( Figs. 22–26 ). Plica located on apical third of urosternite VII, this urosternite with two median processes ( Fig. 26 ). Apex of laterotergite VIII attaining apex of urosternite VII ( Fig. 25 ). Internal margin of gonapophysis VIII a wide arch ( Fig. 24 ). Gonocoxite VIII with tiny tubercles and setae close to sutural and apical margins. Arms of gynatrium sclerite at an almost right angle ( Fig. 23 ). Ductus receptaculi short, curved, but nonspiralled ( Fig. 22 ). Apex of spermathecal bulb rounded ( Fig. 22 ).

Female measurements (mm). Total length 8.1; antennal segments: I—0.9, II—1.0, III—1.3, IV—0.7; head length 1.2; width 1.3; interocular distance 0.8; interocellar distance 0.2; anteocular region 0.7; rostral segments: I— 1.0, II—0.9, III—0.4, IV—0.6; pronotum length 1.5, width 2.8; scutellum length 0.9, width 1.0.

Distribution. BRAZIL, São Paulo: Piracicaba; Rio Grande do Sul (new record): Porto Alegre; Triunfo; Salvador do Sul.
