Graziacrophyma brasiliensis sp. nov.

(Figs. 2, 6, 8)

Acrophyma bicallosa: Faúndez, 2009: 63, 64, figs. 12, 15.

Holotype: Malem Brazil, Nova Teutonia [Santa Catarina], 300–500 m, [27°11’S, 52°23’W], 11/1974, leg. Fritz Plaumann [USNM].

Paratypes: same data as the holotype [DARC] 3♂, [EGER] 4♂ 1♀, [HERC] 1♂, [NMNH] 1♂ .

Etymology: Brasiliensis, from the country of the type locality, Brazil.

General body shape ovate, with posterior half of abdomen narrower (Fig. 2).

Head: wider than long, finely striated transversely, with thick punctation. Anteclypeus broad, with same punctation design as on paraclypei. Paraclypei with apices rounded, semi-pointed. Eyes red, prominent. Ocelli red. First antennomere reaching anterior margin of head. Fourth antennamere longest, remaining segments subequal in size to each other. Last segment of rostrum darker than first three segments.

Thorax: Pronotum with stronger and denser punctures towards anterior margin, with a fine, longitudinal, medial, impunctate line surpassing posterior margins of cicatrices. Scutellum isosceles shaped, with apex rounded, strongly punctate, with a dark patch at base and a callus in each basal angle. Each clavus with three distinct rows of punctures. Hemelytra nearly hyaline, coria with deep punctures, membranes transparent with a brown patch medially. Mesosternal carina wider anteriorly, with reddish border. Ostiolar plate with strong punctures towards the center of the body.

Abdomen: Reddish brown dorsally, connexiva nearly concolorous with rest of body, with several small reddish punctures; sides rounded, slightly convex. Ventrally reddish brown with several impunctate areas irregularly dispersed. Male genitalia: Ventral surface of pygophore smooth. Posterior margin undulate, forming two lateral and two ventral lobes. Each lateral lobe has a rounded edge (Fig. 6). Each ventral lobe has a pair of small pointed, darkened processes. Parameres light brown, lanceolate, with curved, elevated apices. Female genitalia: first gonocoxae “D” shaped, striated longitudinally. Second gonocoxae very small. Each gonocoxite rounded. Paratergites 8 broad, unilobed, overall convex, with a concave portion in middle. Paraergites 9 triangular shaped, with concave margins (Fig. 8).´

Measurements: total length (males n= 10 in parenthesis; females n=1): 8.39 (7.95); head length (apex to base): 1.65 (1.60); head width: 1.70 (1.64); pronotum length: 1.35 (1.32); pronotum width: 4.21 (4.01); scutellum length: 1.84 (1.80); scutellum width: 1.52 (1.49). Antennae: I=0.43, II=0.97, III=0.83, IV=1.18, IV=1.12.

Comments: Graziacrophyma brasiliensis sp. nov. can be separated from G. bicallosa by characteristics of the head and the genitalia of both sexes. The new species has the apices of the paraclypei more pointed, the posterolateral margins of the pygophore are straight, and the lateral margins of the 7 th sternum and gonocoxae in females are more truncate. In G. bicallosa, the apex of the head is more truncate (paraclypei are less pointed), the posterolateral margins of the pygophore are more pointed, and the lateral margins of the 7 th sternum and gonocoxae in females are not as truncate. In addition, G. bicallosa seems to have a more northern distribution (described from Colombia, recorded from Panama) while the new species is distributed in southern Brazil (Santa Catarina).
