description: Hypoxys offuscatus (Breddin, 1907) comb. nov.
(Figs. 7 A–E; 19 A–B; 21)
Edessa offuscata Breddin, 1907: 332; Kirkaldy, 1909: 368 (catalog)
Edessa rimata Breddin, 1907: 338; Kirkaldy, 1909: 368 (catalog) syn. nov.
Lectotype male. Edessa offuscata. Brasil, Pebas (SDEI). Designated by Gaedike (1971:94). Examined.
Lectotype female. Edessa rimata. Peru, Iguapo (SDEI). Designated by Gaedike (1971:97, by use of “ Holotypus ”). Examined.
Material examined. PERU. Loreto: ♀ Iquitos, Amazon River, II–21–1927, H. Bassler (USNM); ♂ ♀ Confl. De los Rios Zamur e Yahuasyacu, II–80, J. Becker leg. Edessa rimata Breddin, 1907 Comp. w. TYPE Fernandes, JAM 1999, Edessa offuscata Breddin, 1907 Comp. w. TYPE Fernandes, JAM 1999. (RMNH).
Measurements. total length: 17.2–19.0; head length: 2.3; head width: 3.4–3.6; pronotal width: 11.0–11.3; abdominal width: 9.6–10.3; length of antennal segments. I: 0.9–1.0; II: 2.4; III: 1.3–1.4; IV: 5.7; V: 6.3; interocular distance: 1.6–1.7; scutellum length: 8.4–9.0; scutellum width: 6.2–6.6; pronotal length: 3.6–3.9.
Diagnosis. Anterolateral margin of pronotum with solid black stripe reaching all its extension. Cicatrices with dark brown punctures delimiting anterior sulci (Fig. 19A). Anterolateral margin with few dark punctures. Male (Fig. 7 A–C). Pygophore with dorsal rim widely excavated (Fig. 7A). Superior process of genital cup small, arrow-headshaped, adjacent to dorsal rim (Fig. 7B). Paramere elongated, shank triangular (cross section) due to a conspicuous carina on inner side ending before enlarged part; head of the paramere spatulate (Fig. 7B). Proctiger with laterodorsal tufts of setae widely separated by medial ridge; posterior face pentagonal, flat (Fig. 7B). Ventral rim with expansions rounded, wide, tumid, well-projected, clearly surpassing level of posterolateral angle in ventral view (Fig. 7C); base of each expansion with a conspicuous transverse carina. Female (Fig. 7D). Gonocoxites 8 with posterior margin sinuous, inner angle rounded projected posteriorly reaching gonocoxites 9; sutural border with elliptic, short excavation on posterior half. Gonapophyses 8 exposed.
Comments. Edessa offuscata and E. rimata were described by Breddin (1907). The author considered E. rimata related to E. trabecula and E. offuscata close to E. quadridens and E. boerneri. However, these similarities are based only on the external morphology of the species. Females of H. offuscatus have inner angles of gonocoxites 8 more protruding and sutural border less excavated (Fig. 7D) than H. boerneri (Fig. 2D); both species have posterior margin of gonocoxites 8 sinuous while H. quadriden s has posterior margin arched (Fig. 1D). Males of H. offuscatus and H. quadriden s are very similar and can be separated by subtle characteristics like paramere more robust and dorsal rim more excavated in H. offuscatus (Fig. 7B and 1B); more obvious distinctive characteristic is the expansion of ventral rim more developed and rounded in H. offuscatus (Fig. 7C) than in H. quadriden s (Fig. 1C).
Distribution (Fig. 21). PERU: Loreto.
