Diagnosis. Coloration uniformly dark with blue metallic bright. Eyes contiguous to anterior margin of pronotum. Rostrum reaching hind coxae. Exocorium fossa of male with elevated edges. Description. Male ( Fig. 1a ). Measurements ( Table 1 ).

Small size (3 to 4.1 mm), uniformly dark-brownish with metallic bright blue. Dorsal surface slightly punctuated on pronotum, with scattered erect pubescence, denser in head, pronotum, and lateral margins of hemelytra. Head lightly twice wider than longer; front declivous; vertex contiguous to collar; rostrum yellowish; antennal segments black, antennal I and II cylindrical, other antennals slender; antennal I shorter than length of vertex between eyes; antennal I, II, and III with dense adpressed vestiture, equal or shorter than width, and antennal IV with erect hairs longer than width of segment; relative lengths of antennal segments from shortest to longest: I<III<II<IV. Pronotum uniformly shining dark blue; posterior margin straight. Legs yellowish to dark with hind femurs larger in their 1/3 basal, with three or four long erect setae in apex; tibiae covered with dense pubescence as long or longer than width of segment. Hemelytra: uniformly dark blue, and covered with scattered pilosity; membrane dark with cubital vein hairy; cuneus as long or slightly longer than wide with apex rounded,cuneal cleft profound. Underside uniformly dark and shining with dense pilosity.

Pachymeroceroides novabadensis new species

Diagnosis. Head, pronotum, scutellum shining black. Hemelytra predominantly shining red, with clavus black and membrane dark; fossa’s edge of exocorium not prominent. Eyes slightly beyond anterior margin of pronotum. Rostrum reaching base of hind coxae.

Description. Male. Measurements ( Table 1 ).

Small species (nearly 4.0 mm), body oblong oval, predominantly shining black with red areas. Dorsal surface covered with golden-yellowish pilosity of adpressed hairs. Head broader than longer and produced anteriorly; front rounded faintly angled between antennal insertion; rostrum yellowish, and slightly beyond lateral margin of pronotum; antennal segments I, II, and III cylindrical, covered with dense adpressed pilosity equal or slightly longer than diameter of segments; antennal segments I and II black, and III whitish; segment IV slender with erect setae longer than diameter of segment; antennal segment I as long as vertex between eyes; relative lengths of antennal segments from shortest to longest: I<III<IV<II. Pronotum uniformly shining black, and covered with adpressed pilosity; posterior margin slightly convex; calli well delimited, surface shining, with concavity between them. Legs yellowish with dark spots at anterior extremity of femora and tibiae; posterior femur wider in their 1/3 basal, with three or four long setae at apex; tibiae with common adpressed pilosity shorter than diameter of segment. Hemelytra predominantly shining red, covered by dense pilosity with region near cuneal fracture broader; clavus black; embolium delimited only in its third basal; cuneus nearly twice longer than wide with profound fracture; corium clearly convex in the posterior region; membrane dark with cubital vein prominent and covered with short pilosity. Male deep fossa internally covered by a dense, short, and adpressed pilosity. ( Fig. 1 c) Underside uniformly shining black, covered by dense yellowish pilosity.

Genitalia. Left paramere ( Fig.2 h) curved with dorsal setae in the region of sensorial lobe; basal region sharpen and the apex forked with two sharp lobes; Right paramere falciform, with anterior portion becoming sharp to apex ( Fig. 2 g).

Pygophore ( Fig 2 l) with posterior margin supporting two distinct areas of spine projections: one area with two different kinds of spines: one straight and the other sinuous; other region with apical region formed by a spine projection and a rounded projection.

Female. ( Fig.1 b) Measurements ( Table 1 ).

Females similar to males in general morphology and color, distinguishing by the fossa in male’s hemelytra exocorium.

Genitalia. Posterior gonapophyses ( Fig.2 j) narrow with apex wider with surface formed by acute teeth. Anterior gonapophyses ( Fig.2 k) sclerotized, slightly angulated; inner surface with rounded, shallow, and scattered teeth.

Geographic distribution. Brazil: Minas Gerais State. This species was found in a region of Atlantic Forest near the municipality of Lambari city, in the south of the State.

Host Plant. Unknown.

Etymology. The specific name was given in reference to the State Park of Nova Baden, Minas Gerais State, Brazil, where the specimens were collected.

Material examined. Holotype: male: Lambari, Nova Baden, BR, Parque Estadual N. Baden, 27/ 02-01/ 03/2008, Grupo Entomofauna. Paratypes: 3 males and 10 females same data of holotype. Deposited in the Regional Museum of Entomology, Federal University of Viçosa, Minas Gerais State, Brazil ( UFVB).
