( Figs 13View FIGURE 13 A–D; 20 A–B; 23)

Edessa brachyacantha Breddin, 1904a: 140  ; Bergroth, 1908: 178; Kirkaldy, 1909: 155 (catalog)

Lectotype male. Bolivia ( SDEI). Designated by Gaedike (1971: 81). Examined. 

Material examined. BOLIVIA. La Paz: ♂ Yungas, 1000 m. From Rolle. EPVanDuzee collection, Edessa brachyacantha Breddin, 1904 Fernandes, J. A. M. 1999 Comp.  HOMOTYPE ( USMN)  ; Santa Cruz: ♂ Sarampiuni, San Carlos , 1000 m., 17–9–1950, leg. W. Forster. Edessa brachyacantha Br. Comp.  w. TYPE P. H. v. Doesburg Jr. det 1978 ( ZSM)  .

Measurements. total length: 15.3–18.1; head length: 1.9–2.2; head width: 3.0–3.6; pronotal width: 9.7–12.3; abdominal width: 8.0–10.3; length of antennal segments. I: 0.7–1.0; II: 1.6–2.0; III: 1.1–1.6; IV: 3.3–4.8; V: 4.3–5.0; interocular distance: 1.4–1.7; scutellum length: 7.1–8.6; scutellum width: 5.2–6.7; pronotal length: 3.3–4.0.

Diagnosis. Anterolateral margin of pronotum without solid black stripe. Pronotum with small, elongated, lateral black spots including posterolateral angles. Connexivum green without spots ( Fig. 20AView FIGURE 20). Anterolateral margin of pronotum not punctured. Anterior margin of scutellum concolorous ( Fig. 20AView FIGURE 20). Black spot of costal margin reaching approximately 1/3 of corial extension. Dorsal surface of abdomen yellow to olive green with brown longitudinal stripe. Ventrally end of pseudosutures with rounded dark spots ( Fig. 20BView FIGURE 20). Male ( Fig. 13View FIGURE 13 A–C). Pygophore with dorsal rim sinuous; median part almost straight ( Fig. 13AView FIGURE 13). Paramere with anterior lobe truncate, reaching superior process of genital cup; posterior lobe triangular and laterally bent ( Fig. 13BView FIGURE 13). Proctiger with widely separated tufts of short setae; posterior face ogival and flat ( Fig. 13BView FIGURE 13). Ventral rim with expansions little developed, flat, and rounded ( Fig. 13CView FIGURE 13). Female unknown.

Comments. Breddin (1904a) related Edessa brachyacantha  to E. pachyacantha  . Here, the species E. pachyacantha  is considered a junior synonym of H. tragelaphus  . Both species are very different; H. tragelaphus  has humeral angles developed and globose ( Fig. 20GView FIGURE 20). Hypoxys brachyacanthus  is similar to H. leptacanthus  in size and spots on pronotum, but H. leptacanthus  has dorsal rim of the pygophore projected beyond posterolateral angles (not projected in H. brachyacanthus  ) ( Figs. 15AView FIGURE 15, 13AView FIGURE 13).

Distribution ( Fig. 23View FIGURE 23). BOLIVIA: La Paz, Santa Cruz.
