Group H. triangularis

( Figs. 9–11 View FIGURE 9 View FIGURE 10 View FIGURE 11 A–E; 19 E–J; 22)

Diagnosis. This group compared with H. quadriden s group is characterized by absence of features. Species belonging to H. triangularis group can be identified by the general and uniform green color ( Fig. 19H,J View FIGURE 19 ) (except H. triangularis ), except for a median large yellow spot on abdominal venter ( Fig. 19F View FIGURE 19 ); and typically, without any transversal dark stripe on ventral surface ( Fig. 19F,H,J View FIGURE 19 ). This group also doesn’t have the anterolateral margin of pronotum black ( Fig. 19E,G,I View FIGURE 19 ). Doesn’t have a transversal dark stripe on pronotum, except H. triangularis , that is a striking characteristic of the rest of the species groups of Hypoxys. Connexivum without black spots ( Fig. 19E,G,I View FIGURE 19 ). Males have the head of paramere usually with a single lobe elongated and anteriorly directed ( Fig. 9B View FIGURE 9 ). Females share the outer lateral angle of gonocoxites 8 varying from a small tooth to a large acute projection ( Figs. 9D View FIGURE 9 , 10D View FIGURE 10 , 11D View FIGURE 11 ).

Head. Mandibular plates with apices concolorous; lateral margin without spot. Antennae yellow with setae more densely distributed in antennomeres III, IV and V; third antennomere longer than second ( Fig. 19E,G,I View FIGURE 19 ).

Thorax. Apex of humeral angle with margin brown. Scutellum with punctures black; anterior margin without a yellow stripe ( Fig. 19G View FIGURE 19 ). Propleura with punctures concolorous concentrated on posterior half. Evaporatorium concolorous to slightly whitish. Metasternal process ( Fig. 9E View FIGURE 9 ) with anterior bifurcation receiving fourth and most of third rostral segment.

Abdomen. Connexivum with two barely excavated areas ( Fig. 19E,G,I View FIGURE 19 ). One trichobothrium positioned in line with spiracles and the other located laterad of this line.

Male. Pygophore with distal part of dorsal surface coarse and reddish brown ( Figs. 9A View FIGURE 9 , 10A View FIGURE 10 , 11A View FIGURE 11 ). Superior process of genital cup black, emarginated, and placed near base of proctiger. Base of paramere with a rounded protuberance ( Fig. 9B View FIGURE 9 ).

Female ( Figs. 9D View FIGURE 9 , 10 View FIGURE 10 , D, 11D View FIGURE 11 ). Gonocoxites 8 convex. Gonocoxites 9 with distal margin straight to slightly concave. Laterotergites 9 with outer lateral margin sinuous, well projected beyond sclerite uniting laterotergites 8; almost reaching level of laterotergites 8.

This group of species includes: H. triangularis , H. capito , H. subrastratus , and several new species.
