( Figs 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. 20A ). Anterolateral margin of pronotum not punctured. Anterior margin of scutellum concolorous ( Fig. 20A ). 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. 20B ). Male ( Fig. 13 A–C). Pygophore with dorsal rim sinuous; median part almost straight ( Fig. 13A ). Paramere with anterior lobe truncate, reaching superior process of genital cup; posterior lobe triangular and laterally bent ( Fig. 13B ). Proctiger with widely separated tufts of short setae; posterior face ogival and flat ( Fig. 13B ). Ventral rim with expansions little developed, flat, and rounded ( Fig. 13C ). 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. 20G ). 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. 15A , 13A ).

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