Psyllobora bicongregata Boheman, 1858:203 , Crotch, 1874:141; Weise, 1926:11; Blackwelder, 1945: 455 as synonym of P. picta ; Mader, 1957: 24; Gordon, 1987:17 as synonym of P. picta ( González, 2008:95; 2013:52, 2014:530; Serra et al., 2013:237.

Psyllobora pavida Weise, 1904:195 ; Blackwelder, 1945: 455; Mader, 1957:24.

Male genitalia: Tegmen 3.6 times longer than wide on average, phallobase subrectangular, as long as wide and with rounded bor- der. Terminal strut short, 1/3 of phallobase length. In dorsal view, penis guide with gently sinuous sides, with a sinuosity at 3/5 of length and almost parallel sides, reduced to 4/5 of basal width at 5/6 of length, then tapering sharply in triangle in apical 1/6 to end in mamilliform projection in apical 1/12; in lateral view with yellowish ventral semicircular projections very wide, twice width of paramere, in 1/3 distal apex curving to parameres. Parameres in dorsal view narrow and slightly curved, 1/6 shorter than basal lobe, distal half with long pubescence, which exceeds paramere by over half its length ( Figs. 49–51). Penis wide, about 1/6 of maximum length, basal half semicircular, then gently curving to 2/3 length with straight distal 1/3. Apex occupying 1/6 of length and slightly wider than penis tube, separated from it by almost perpendicular union, with ejaculatory duct “S” shaped and sclerosed spine on inner apex; penis capsule, inner branch hook-shaped, outer branch twice as wide as internal, basal margin convex, sometimes somewhat emarginate to center ( Fig. 48).

Female: Similar to male. Spermatheca “C” shaped, about eight times longer than wide, lateral nodulus quite short, ramus 1/6 of total length, seminal duct short, infundibulum irregularly anchor shaped, half size of spermathecal ( Fig. 52). Coxites paddle-shaped, with very wide apex and evident stylus.

Variation: Length 1.9–2.7 mm. Dorsal color varies from light brown to yellowish ivory, spots brown with darkened borders, outer spots usually homogeneously dark brown, sometimes some of discal spots dark brown. Head spots varying in size and color. Pronotal spots varying in size, sometimes joined on same side, some specimens with small spots on border of pronotum. Elytral spots quite variable, always separate from suture, usually spots 1–3 and spots 5–7 joined, other spots sometimes lightly touching. Supernumerary spots usually between spots 5, 7 and suture, sometimes very light in color, apical spot usually distinct, very light in color, sometimes blurry. Spot 6 often separated into two small longitudinal spots. Ventral surface light brown, usually with darker brown metaventrite ( Figs. 40, 44–47). In one case, we observed only spots 1, 2 and 4 and an entirely clear ventral surface, perhaps an immature specimen.

Geographical distribution: Argentina (from Neuquén north), Uruguay, Paraguay and southern Brazil (Paraná) ( Fig. 53 ).

Discussion

The taxon P. bicongregata was long maintained in synonymy with P. picta . However, their morphological characteristics, especially the male genitalia, allow the species to be clearly distinguished (see species key). The presence of P. bicongregata in Chile is discarded, since specimens previously assigned to this taxon actually represent the new species described here, P. pauline sp. nov. and P. lueri sp. nov.
