Hypoxys striatus sp. n.
(Figures: 2, 8F, 9F, 10C–D, 12)
Etymology. The specific epithet refers to the paramere posterior face striated.
Holotype. BRAZIL. Pará : 1 ♂ Óbidos, VIII.1978, A. C. Domingos Coll. ( MNRJ).
Paratypes (n=3). BRAZIL. Pará: 1 ♀ Óbidos , XII.1963, Dirings Coll. ( MZUSP) ; 1 ♀ e 1 ♂ Santarém, VI .1919, S. M. Klages Coll. ( CMNH) .
Measurements. Total length 14.3–14.8; total width 7.7–8.0; head length 1.4–1.5; head width 3.2–3,4; interocular distance: 1.6–1.8; length of antenomeres I: 0.9–1.0; II: 1.0–1.1; III: 1.5; IV: 3.1–3.2; V: 3.6; pronotum length 2.7– 3.0; pronotum width 8.9–9.2; scutellum length 6.5–6.7; scutellum width 5.0–5.3.
Diagnose. Antennomeres with increasing lengths progressively (I<II<III<IV<V). Anterolateral margin of pronotum not punctured ( Fig. 10C View FIGURE 10 ). Corium reddish brown ( Fig. 10C View FIGURE 10 ). Metasternal process with arms of anterior bifurcation receiving 2/3 of third rostral segment ( Fig. 10D View FIGURE 10 ). Pseudosutures of abdomen with adjacent dark green spot ( Fig. 10D View FIGURE 10 ). Male genitalia. Dorsal surface with spot restricted to coarse area of the pygophore ( Fig. 2A View FIGURE 2 ). Dorsal rim sinuous ( Fig. 2A View FIGURE 2 ); lateral expansions slightly globose and almost level with posterolateral angles ( Fig. 2C View FIGURE 2 ). Superior process of the genital cup subtriangular, small and swollen ( Fig. 2B View FIGURE 2 ). Paramere with head slightly concave; anterior and posterior lobe subtriangular; anterior lobe large with external face striated and reaching superior process of the genital cup; posterior lobe smaller than the anterior lobe and laterally directed ( Fig. 2D View FIGURE 2 ). Proctiger shallowly excavated laterally, excavation covered by long and dense setae; posterior face elliptical ( Fig. 2B View FIGURE 2 ). Inner wall with small swollen area contiguous to posterolateral angles ( Fig. 8F View FIGURE 8 , black arrow). Ventral rim in widely opened V-shaped with expansions hardly visible ( Fig. 2C View FIGURE 2 ). Female genitalia ( Fig. 2E View FIGURE 2 ). Valvifers VIII with distal margin slightly arched; outer and inner angles of the posterior margin rounded; mediolateral crest slightly swollen ( Fig. 9F View FIGURE 9 , black arrow); mesial borders with excavation narrow, deep and U-shaped. Valvulae IX clearly exposed.
Distribution ( Fig. 12 View FIGURE 12 ). BRAZIL: Pará.
Comments. The superior process of the genital cup of H. triangularis and H. striatus sp. n. are the smallest processes in the group, but in H. triangularis it is rounded and concave and in H. striatus sp. n. it is subtriangular and swollen. This species is the only one with expansions of the ventral rim hardly visible. The mesial borders of the valvifers VIII of H. curvatus sp. n., H. capito and H. subrastratus have the excavation forming a “U”. However, H. striatus sp. n. can be separated from the other two species by the more deeply excavated mesial borders.
