( Fig. 6 )

Material examined: Holotype: female, Manaus , AM, Brasil Reserva KM 41 - trilha EE Biotopo: B- SB Armadilha Suspensa 13-14. X. 2004 Silvia, R.B. Col. ( DCBU).

Diagnosis. Head in dorsal view with gena slightly concave; postgenal process laterally indistinct, forming a tooth that is horizontally oriented to the center of the head; antenna with 51 flagellomeres; propodeum with anterior transverse carina forming a smooth arc; metasoma with tergite I slightly longer than mesosoma.

Description. Female.

Head. Head in dorsal view with gena behind eyes slightly concave; posterior ocellus separated from eye by 1.3× its own maximum diameter; postgenal process present, but laterally indistinct, gena with ventroposterior angle modified to form a tooth narrow at base, and not appreciably tapered towards its apex; antenna with 51 flagellomeres, flagellomere I 1.2× as long as flagellomeres II and III combined.

Mesosoma. Mesoscutum smooth with sparse setiferous punctures; scutellum in profile anteriorly slightly convex, then abruptly and evenly declivous; propodeum with area basalis elongate, tapered posteriorly, about 1.9× as long as broad; propodeum with anterior transverse carina forming a smooth arc; pleural carina present; area lateralis about 1.5× as long as broad; mesosoma 3.15 mm; mesosoma about equal to length tergite I. Fore wing 7.95 mm long, hind wing 5.4 mm.

Metasoma. Tergite I 3.15 mm; metasoma with tergite I exceptionally slender, slightly longer than mesosoma from pronotal collar to posterior margin of propodeum. Ovipositor 6.0 mm. Hind tibia 2.4 mm.; visible part of the ovipositor 2.2-2.5× as long as posterior tibia.

Coloration ( Fig. 6 ). Head mostly dull yellow: apex of mandibles, frons, interocellar area and most of gena black; antenna mostly black, scape ventrally yellow, flagellomeres 32-40 white. Mesosoma half black, half yellow: pronotum anteriorly yellow, posteriorly mostly black; mesopleuron mostly yellow; epicnemium, surrounding area, and a big rounded spot at upper hind margin black; mesoscutum mostly black, with anterior, lateral and hind margins with yellow spots; scutellum and postscutellum yellow; most of metapleuron and metasterna black, hind margin yellow; propodeum with 2/3 anterior mostly black (with two rounded anterolateral yellow spots at spiracularis area), hind 1/3 yellow. Fore leg yellow. Mid legs: coxa yellow with a brown spot at outer side; trochanter with 2/3 basally brown, the rest and trochantellus yellow; femur mostly brown with distal apex yellow; tibia yellow infuscate; tarsomeres mostly brown, with distal apex yellow. Hind leg mostly brown: basally and distally yellow; trochanter mostly brown, distally yellow; trochantellus yellow; femur centrally orange, distally yellow, the rest brown; tibia brown with apex yellow; tarsomere similar to mid legs. Fore wing hyaline with a distal brownish spot, pterostigma brown. Metasoma with tergite I mostly black, anterolaterally (passing the level of spiracles) with yellow stripes and distally dull yellow; tergites II to VIII dull yellow; sterna I brown, rest of sterna mostly yellow. Ovipositor sheath brown.

Remarks. Grotea manausi sp. n. is most similar to G. surinamese sp. n. in color pattern and in several morphological features (e.g. postgenal process present and anterior transverse carina forming a smooth arc). However, the postgenal process is laterally indistinct in G. manausi and distinct in G. surinamese (Fig. 7). Grotea manausi differs from other black and yellow Grotea species from Chile and Colombia in having a fore wing hyaline with a distal brownish spot ( Fig.6 ).

Etymology. The name refers to the type locality: Manaus ( Brazil).
