Measurements. total length: 16.2–19.0; head length: 2.1–2.4; head width: 3.2–3.7; pronotal width: 10.0–11.6; abdominal width: 9.0–10.2; length of antennal segments. I: 0.8–1.0; II: 1.6–2.2; III: 1.1–1.7; IV: 4.1–5.6; V: 5.0–6.2; interocular distance: 1.4–1.7; scutellum length: 7.3–9.3; scutellum width: 5.7–6.8; pronotal length: 3.3–3.9. Diagnosis. Anterolateral margin of pronotum with solid black stripe reaching all or part of its extension with remaining part smoky black and narrow. Cicatrices of pronotum with concolorous punctures delimiting anterior sulci ( Fig. 18A ). Anterolateral margin not punctured. Male ( Fig. 1 A–C). Pygophore with dorsal rim sinuous and shallowly excavated ( Fig. 1A ). Superior process of genital cup elongate, elliptic with a ventral notch and adjacent to dorsal rim ( Fig. 1B ). Paramere elongate, spatulate, broad distally, anteriorly curved touching superior process of genital cup ( Fig. 1B ). Proctiger with dorsolateral tufts of setae separated by tumid ridge; posterior face subrectangular and slightly tumid ( Fig. 1B ). Ventral rim with expansion acuminate, flat, surpassing level of posterolateral angle in ventral view ( Fig. 1C ); base of each expansion with a small transverse carina. Female ( Fig. 1D ). Gonocoxites 8 posterior margin slightly sinuous, inner angle projecting over gonocoxites 9, sutural border slightly divergent distally. Gonapophyses 8 barely exposed. Comments. The type series of E. quadridens is formed by four specimens (all in Copenhagen, but part belonging to Kiel collection), three males and one female. Male without head presented in this paper ( Fig. 1F ) was photographed by Pieter van Doesburg as the lectotype of the species several years ago and we are confirming his selection. Breddin (1907) made it clear that he had not seen the type of E. quadridens , and postulated that the best candidate to be E. quadridens was E. jugalis . We confirm Breddin’s supposition considering E . jugalis junior synonym of H. quadriden s . The male of Hypoxys quadridens shares with H. offuscatus the paramere spatulate ( Fig. 7B ), but both species can be separated by the dorsal tumid ridge narrow of proctiger ( Fig. 1B ), and expansion of ventral rim of pygophore acuminated ( Fig. 1C ) in H. quadriden s (dorsal ridge not tumid and wide, and expansion of ventral rim rounded and tumid in H. offuscatus ). The female of H. quadriden s can be confused with H. trabeculus (see H. trabeculus comments for differences between these two species). A few female specimens of H. oxyacanthus with solid black stripe on posterior part of pronotum can be confused with H. quadriden s , but punctuation of pronotum is different ( Fig. 18A and 19K ) and gonocoxites 8 of H. quadriden s are more convex than in H. oxyacanthus .
