( Figs. 1–3 View Figs ).
Description
Total length 13.1. Body elongate, oval and depressed. Dorsal coloration ochraceous with piceous coarse punctation ( Fig. 1 View Figs ). Head length 2, width 2.1. Jugae long, pointed anteriorly and distinctly exceeding the apex of clypeus, dorsal surface concave with lateral margins raised; eyes carmine-red, oval, interocular distance 1.3; ocelli pale-red, interocellar distance 0.7, distance between the ocelli two times the distance from ocellus to eye. Head with punctures forming a curved line extending from base of head to base of jugae, and surrounding the ocellus. Head with scarce erect setae, more evident on jugae, antenniferous tubercles and margin of bucculae. Antenniferous tubercles stout, with lateral and ventral short piceous projections; insertions of antennae visible from above; length of antennal segments: 0.9; 1.7; 1.4; 1.9. First segment widened toward apex, exceeding apex of jugae; second and third cylindrical, fourth fusiform; antennae pale brown, first segment darker distally; setose, two basal segments with blackish brown setigerous tubercles. Rostrum reaching the metasternum. Rostral segments length: 0.7; 0.3 + 1.3; 1.2; 1.2. Bucculae rounded, covering most of rostral segment I in lateral view ( Fig. 2 View Figs ). Pronotal length (at midline) 2.3, width 5, sub-trapezoidal; anterior angles flat and produced forward into a long tooth reaching the middle of eyes ( Fig. 2 View Figs ), lateral margins reflected and conspicuously notched on anterior half, posterior margin adjacent to scutellum straight with an apparent longitudinal medial pale brown line that extends on scutellum. Pronotum with abundant dark coarse and shallow small punctures; almost glabrous with very short setae emerging from dark punctures. Scutellar length 4.6, width (at base) 3.1, long and flat, with apex slightly acute. Scutellum with abundant dark coarse punctures, and shallow small punctures restricted to basal half; glabrous. Hemelytra surpassing abdomen, glabrous; membrane testaceous, with simple veins. Pleura ochraceous, coarsely punctated; acetabular area and metapleura with less evident punctures; spout peritreme ochraceous and elongate, located anteriorly to the ostiole. Legs ochraceous, femora and tibiae with blackish brown setigerous tubercles, larger (toothlike) on apical ventral half of femora (anterior legs missing). Tibiae with longer and abundant setae distally. Abdominal width 5.2. Protuberance of the third abdominal segment stout, obtuse, directed forwardly at middle, not reaching the hind border of metasternum; abdominal sternites brown, anterior margin of segments III to VII dark brown, paler dorsally, segment VII and genital segments irregularly pigmented dark brown; spiracles concolor, located slightly before the middle of each segment. Abdomen with semierect setae.
Genitalia. Gonocoxites 8 subtriangular, longer than wide, disc uniformly convex; posterior margins subrectilinear, posterolateral angles obtuse. Laterotergites 8 triangular, longer than wide; posterior margins subrectilinear; spiracles placed posterior to posterolateral angle of gonocoxites 8. Gonocoxites 9 exposed, triangular.
Laterotergites 9 elongate and rounded apically, with the lateral basal region depressed; mesial margins not juxtaposed; apices not surpassing the band connecting laterotergites 8. Segment X visible ( Fig. 3 View Figs ).
Type material
Holotype female, Argentina, Misiones, Iguazú National Park, Macuco Trail , 25 ◦ 40 ' 40.8 '' S 54 ◦ 26 ' 55.9 '' W, 29-X-2012, light trap ( MLP). GoogleMaps
Etymology
The specific name singularis means “alone”, in reference to the unique specimen found of this species.
Remarks
Among the nine species of Adoxoplatys , four species presented an elongate, subparallel sided body: A. brasiliensis , A. giaii , A. willineri and A. singularis . These species can be separated by the morphology of the anterior pronotal angles; in A. brasiliensis the anterior pronotal angles are anteriorly directed and sickle shaped, in A. willineri ( Fig. 6 View Figs ) the anterior pronotal angles are small and directed laterally; and in A.giaii and A. singularis the anterior pronotal angles are produced forward, but in A. giaii it is straight and placed well alongside the eyes ( Fig. 5 View Figs ), while in A. singularis it is triangular, shorter and remote from the eyes. These two species also differs in the shape of the posterior margins of the gonocoxites 8, in A. singularis are subrectilinear while in A. giaii are slightly concave ( Fig. 4 View Figs ).
A. singularis is the third species of the genus Adoxoplatys known from Argentina, A. giaii and A. gallardoi are also known from Misiones Province, and presumably also inhabitants of the Paranaense forest. A. gallardoi has an oval shortest body and the jugae are as long as the clypeus ( Fig. 7 View Figs ).
