Treatment

Canthysellus putkarot sp. nov.

( Figs 2 View Figs 1–4 , 6a–e View Figs 5–8 )

Type locality. Brazil, Pará State, FLONA Carajás, Parauapebas Municipality, Serra Norte, Buritizal 1, 06°04′51.89″S 50°08′02.27″W.

Type material. HOLOTYPE: J, ‘ Brazil : Pará State , FLONA Carajás , Parauapebas Municipality , North Sierra, Buritizal 1, low part, (stream) above puddles, 06°04’51,89”S 50°08’02,27”W, 29.IX.2007, Ferreira-Jr. N. & Alecrim V.P. leg.’ ( DZRJ 6061 ) GoogleMaps . PARATYPE: BRAZIL: PARÁ: ‘Brazil: Pará State, FLONA Carajás, Parauapebas Municipality, Buritizal 2, puddle with foliage, 06°04’56,90”S 50°08’04,93”W, 08.IX.2006, Ferreira-Jr.N.& Dumas L.L.leg.’ (1J / DZRJ 6062).

Diagnosis. Canthysellus putkarot sp. nov. can be distinguished from other species in the genus by the following characteristics: large size, 3.35–3.40 mm; pronotum and elytra smooth ( Fig. 2 View Figs 1–4 ); prosternal process completely covered by short setae; median lobe of aedeagus, in lateral aspect, elongate and thin with dorsobasal margin sharply narrowing before midlength ( Figs 6a, c View Figs 5–8 ).

Description of holotype. Body outline, in dorsal view oval ( Fig. 2 View Figs 1–4 ), as in C. kukrutkato sp. nov.

Color ( Fig. 2 View Figs 1–4 ). Head and pronotum light reddish-brown. Elytra blackish, each elytron with four light reddish-brown maculae: one laterally, a second on disc, both just anterior to midlength of elytron, and a third near suture, these three markings appearing as an arched and interrupted transverse band; finally, a fourth short transverse macula on distal third. Ventral surface light reddish-brown.

Head. Surface smooth and shiny. Antennae and palpi similar to those in C. kukrutkato sp. nov.

Thorax. Pronotum smooth and shiny, with transversal row of punctures bearing long and slender setae in anterior margin. Prosternum with dense, transverse tuft of four stiff setae at middle of discal surface ( Fig. 9 View Figs 9–10 ); line of setae continuous medially, not extending beyond lateral margins of prosternal process. Prosternal process and noterid platform completely covered by short and stout setae, distinctly spaced and evenly distributed. Elytron smooth and shiny, with three longitudinal rows of punctures bearing long and slender setae. Metatibia with series of 12 evenly spaced spiniform setae at posteroventral margin. Metatarsomere I with similar row of four setae on posteroventral margin.

Abdomen. Ventral surface as in C. kukrutkato sp. nov.

Aedeagus. Median lobe in lateral aspect elongate and thin, with ventral margin curved; dorsobasal margin sharply narrowing before midlength of median lobe and apex curved dorsally and rounded ( Figs 6a, c View Figs 5–8 ); a long carina occurs on left side arising basally and ceasing apically, constituting the major part of left side ( Figs 6a–c View Figs 5–8 ); in dorsal aspect, straight with apex slightly curved ( Fig. 6b View Figs 5–8 ). Left lateral lobe, in lateral aspect, slender with a dense tuft of setae at apex; setae distinctly extending beyond dorsal margin ( Fig. 6d View Figs 5–8 ). Right lateral lobe, in lateral aspect, broad and rounded ventrally ( Fig. 6e View Figs 5–8 ).

Variation. Due to the scarceness of specimens available, it is not possible to assess intraspecific variation.

Measurements. Holotype: TL = 3.35 mm; MW = 1.85 mm; HW = 0.95 mm; EW = 0.60 mm; PntB = 0.05 mm; AntVII = 0.05 mm. Paratype: TL = 3.40 mm; MW = 1.80 mm; HW = 1.00 mm; EW = 0.60 mm; PntB = 0.05 mm; AntVII = 0.05 mm.

Etymology. The specific name refers to ‘Putkarôt’, the name by which the Xikrin call themselves, in honor of the indigenous people present in the area of origin of the holotype. It is a noun in the nominative singular standing in apposition.

Geographic distribution. So far Canthysellus putkarot sp. nov. is known only from the Floresta Nacional de Carajás, Parauapebas Municipality in the Brazilian state of Pará.
