Notes on Suphis intermedius Régimbart, 1903

( Figs 2 View FIGURES 1–5 , 15 View FIGURES 12–15 , 19–23 View FIGURES 19–25 )

We take the opportunity to report new locality data extending the distribution of this species, and to illustrate its male genitalia for the first time, with the purpose of comparing them with those of S. fluviatilis (see differential diagnosis above). Type material examined. BRAZIL: Mato Grosso State. 15 syntypes, labelled “ MNHN / EC10415 About MNHN ” to “ MNHN / EC10429 About MNHN ” [typed, white labels]: “Brésil / Prov. Matto-Grosso / P. Germain / 1886” [typed, white label], “intermedius Reg ” [handwritten, white label], “ MUSEUM PARIS / 1952 / coll. R. OBERTHÜR” [typed, white label], “ SYNTYPE ” [typed, red label], “SYNTYPE / Suphis / intermedius Régimbart , / 1903” [typed, white label]. 1 syntype labelled “ MNHN / EC10413 About MNHN ” [typed, white label]: same data as above except that the label “ MUSEUM PARIS / 1952 / coll. R. OBERTHÜR” is replaced by “ MUSEUM PARIS / COLL. MAURICE REGIMBART / 1908” [typed, light blue label]. 1 syntype labelled “ MNHN / EC10414 About MNHN ” [typed, white label]: same data as above except without the label “intermedius Reg ”. Additional material examined. BRAZIL: Mato Grosso State. 2 ♁♁ (habitus and male genitalia in Figs 15 View FIGURES 12–15 , 19–21 View FIGURES 19–25 ), 1 ♀ and 36 exs, Corumbá, Col. Zimmermann ( ZSM) . PARAGUAY: Canindeyú Department. 2 ♀♀ (habitus in Fig. 22 View FIGURES 19–25 ), Reserva Natural del Bosque Mbaracayú , 14.XII.2003, Col. Di Iorio ( LEBA) .

Diagnosis. TL = 2.8–3.25 mm. [mean = 3.00 mm]. Background color brownish-red, elytra marmorated ( Figs 2 View FIGURES 1–5 , 19, 21, 22 View FIGURES 19–25 ); dorsal surface with macro- and micropunctation ( Fig. 23 View FIGURES 19–25 ); pronotum with 16 spots, with central spots smaller, subcircular and well defined ( Figs 2 View FIGURES 1–5 , 19, 21, 22 View FIGURES 19–25 ); lateral margins of metacoxal processes divergent posteriorly ( Fig. 20 View FIGURES 19–25 ); male genitalia as in Fig. 15 View FIGURES 12–15 : left lateral lobe bearing a single tuft of setae ( Fig. 15b View FIGURES 12–15 ), median lobe in lateral view ( Figs 15d, f View FIGURES 12–15 ) with apex rounded, in dorsal view ( Fig. 15e View FIGURES 12–15 ) with base comprised of perpendicular lateral notches.

Male genitalia ( Fig. 15 View FIGURES 12–15 ). Aedeagus asymmetrical; right lateral wall of segment IX rhomboid-like ( Fig. 15a View FIGURES 12–15 ), posterior margin with notch, ventral lobe more projected backwards, apex of left lateral wall of segment IX (only part of this structure could be observed) pointed; left lateral lobe in lateral view ( Fig. 15b View FIGURES 12–15 ) relatively elongate, slender, slightly curved, with single tuft of hair-like setae on distal third, longer at apex; right lateral lobe in lateral view ( Fig. 15c View FIGURES 12–15 ) relatively short, robust, with deep longitudinal groove on dorsal side, creating an inward fold, left lateral flange reduced ventrally, apex with setae of different lengths; median lobe ( Figs 15d–f View FIGURES 12–15 ) longer than lateral lobes, in lateral view robust, width nearly uniform along its length, apex rounded; slightly curved dorsally at about mid length, ventrally with deep longitudinal groove subtended by lateral flanges, left lateral flange slightly enlarged, expanded ventrally, converging with right side at or near apex; in dorsal aspect, slightly curved to the left side; base large, comprised of perpendicular lateral notches.

Distribution. So far, the species was known only from Brazil ( Grosso 1993). Here we add the first record from Paraguay.
