Hypoxys triangularis


Group H. triangularis 

( Figs. 9–11View FIGURE 9View FIGURE 10View 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,JView FIGURE 19) (except H. triangularis  ), except for a median large yellow spot on abdominal venter ( Fig. 19FView FIGURE 19); and typically, without any transversal dark stripe on ventral surface ( Fig. 19F,H,JView FIGURE 19). This group also doesn’t have the anterolateral margin of pronotum black ( Fig. 19E,G,IView 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,IView FIGURE 19). Males have the head of paramere usually with a single lobe elongated and anteriorly directed ( Fig. 9BView FIGURE 9). Females share the outer lateral angle of gonocoxites 8 varying from a small tooth to a large acute projection ( Figs. 9DView FIGURE 9, 10DView FIGURE 10, 11DView 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,IView FIGURE 19).

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

Abdomen. Connexivum with two barely excavated areas ( Fig. 19E,G,IView 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. 9AView FIGURE 9, 10AView FIGURE 10, 11AView FIGURE 11). Superior process of genital cup black, emarginated, and placed near base of proctiger. Base of paramere with a rounded protuberance ( Fig. 9BView FIGURE 9).

Female ( Figs. 9DView FIGURE 9, 10View FIGURE 10, D, 11DView 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.
