Description. Male. Coloration: Dorsum black and yellow. Frons, vertex, juga, and lora shiny black. Clypeus black. Eyes reddish, posterior margins yellowish. Labium yellow, apex brown; buccula black. Antennal segments I– III uniformly black, antennal segment IV light brown apically, black basally. Pronotum and mesoscutum uniformly shiny black. Scutellum black, the apex brown. Clavus shiny black, yellowish to apex, narrowly yellowish brown along clavo-corial suture, the suture itself black. Corium dark brown to black, yellow basally and apically, the embolium yellow. Cuneus yellow, paracuneus brown. Membrane (including veins) brownish, with two whitish spots close to cuneus apex. Meso- and metapleuron shiny black. Evaporatorium brown. Coxae yellow, femora, tibiae, and first tarsal segments yellowish brown, last tarsal segment brown. Abdominal sternites and pleurites black with a posterior yellow stripe, the pygophore black.

Surface and vestiture: Frons and vertex narrowly and shallowly but densely punctate, almost glabrous. Antennal segments covered with semi-recumbent, short setae. Pronotum, mesoscutum and scutellum almost glabrous, punctate, the punctures relatively wide and deep. Hemelytra almost glabrous, obviously punctate, the punctures relatively wide and deep. Membrane glabrous.

Structure: Frons slightly swollen. Eyes removed from ventral margin of head by a distance subequal to 1/3 of eye height in lateral view. Cuneus translucent. Detailed measurements in table 1 .

Genitalia: Left paramere as in Fig. 5A . Right paramere as in Fig. 5B . Endosoma coiled, the secondary gonopore reduced, subapical, elongate-oval, slightly pointed basally ( Fig. 5D ). Apical process sclerotized, pointed apically, reaching beyond the secondary gonopore. Phallotheca as in Fig. 5C .

Female. Coloration: Yellowish, yellowish brown, orangish brown, and black. Frons, vertex, juga, lora, and clypeus orangish brown. Eyes reddish, posterior margins yellowish. Labium yellow, with apex black. Antennal segments I and II uniformly brown, antennal segments III and IV almost black. Pronotum yellowish brown, lighter medially, laterally and apically. Pronotal callosities black. Scutellum yellow, the tip slightly lighter. Clavus shiny yellow, punctures orangish brown. Corium yellow, the apex with a brown spot. Cuneus yellow, paracuneus brown. Membrane (including veins) brownish, paler apically. Legs yellowish brown, apex of last tarsal segment and claws darker.

Surface and vestiture: As in male, almost glabrous. Punctures slightly more reduced on scutellum.

Structure: As in male. Detailed measurements in table 1 .

Distribution. Argentina: Mendoza.

Host plant. Adesmia pinifolia Gill. ex Hook. & Arn. ( Fabaceae ) ( Fig. 6D ).

Etymology. The authors are delighted to dedicate this new species to Prof. Aleksander Herczek on the occasion of his 70 th birthday for his major contributions to plant bug taxonomy, particularly but not exclusively fossils.

Discussion. A. herczeki , n. sp. differs from A. manzanoensis , n. sp. by the dorsal coloration and the male genital structures. In A. herczeki , the secondary gonopore is elongate oval, slightly pointed basally. The apical process of endosoma is longer than in A. manzanoensis ( Figs 5E–F ), and its shape is slightly different.
