Grotea goianiense Herrera-Fl��rez sp. n. (Fig. 1) Material examined. Holotype: female, BRAZIL: Fazenda Aceiro Jatai, Goi��s, X-1962 Expedic��o Departamento Zoologia (DCBU). Diagnosis. Head in dorsal view with gena slightly concave; gena with ventroposterior angle modified to form a conspicuous sharp tooth; antenna with 49 flagellomeres. Propodeum with anterior transverse carina centrally indented. Description. Female. Head. Posterior ocellus separated from eye by 1.5�� its own maximum diameter; postgenal process present, laterally distinct (gena close to junction of occipital and hypostomal carinae with ventroposterior angle modified to form a conspicuous acute tooth); antenna with 49 flagellomeres, flagellomere I 0.9�� as long as flagellomeres II and III combined. Mesosoma. Mesosoma 3.25 mm; mesoscutum smooth with isolated inconspicuous punctures; scutellum in profile convex. Propodeum with pleural carina present; posterior transverse carina, centrally absent; lateral longitudinal carina absent; area spiracularis enclosed, posteriorly and laterally, though mesally not clearly separated from area externa; area lateralis not enclosed internally, rectangular, about 2.6�� as long as broad; with posterolateral corner at right angle close to lobe surrounding coxal insertion. Hind tibia 2.1 mm. Mesosoma 1.03�� as long as tergite I. Fore wing 7.5 mm long, hind wing 4.8 mm. Metasoma. Metasoma with tergite I slender (3.15 mm), slightly shorter than mesosoma (from pronotal collar to posterior margin of propodeum). Ovipositor 4.3 mm; visible part of the ovipositor 2.05�� as long as posterior tibia. Coloration (Figs 1). Head light yellow, apex of mandibles black; frons, interocellar area and part of upper part of gena brown; antenna mostly brown, scape and pedicel ventrally yellow. Mesosoma mostly orange: pronotum with anterior and posterior margins narrowly yellow; propodeum mostly yellow, with a small orange spot toward the posterior margin; mesopleuron with most of its anterodorsal part, a spot at the ventroposterior margin, and area delineated by the mesopleural suture (i.e. after that suture) yellow; mesoscutum with a median yellow spot on midline towards posterior margin; scutellum and dorsellum yellow; propodeum mostly orange, posterior margin yellow. Fore leg yellow. Mid legs mostly yellow with brown spots on trochanter (ventrally); femur and tibia partly brown on inner face; tarsomeres I-IV mostly brown, distally yellow; tarsomere V brown. Hind leg with coxa mostly yellow, centrally brown; trochanter mostly brown, distally yellow; trochantellus yellow; femur mostly (2/3) orange, distally (1/3) yellow; tibia mostly brown, distal dorsal apex yellow; tarsomeres mostly brown with some yellow spots at distal apex of tarsomeres I and II. Wings hyaline, pterostigma brown. Metasoma mostly brown: tergite I with a yellow stripe after spiracle level, not reaching the posterior apex; tergites I-V with triangular yellow spots on distal margin; tergites VI-VIII with yellow stripes distally; laterotergites IV-VIII partially yellow. Ovipositor sheath dark brown. Remarks. Grotea goianiense sp. n. most closely resembles G. paulista sp. n. and G. perplexa, but differs from G. paulista in the shape of the genal tooth which is sharp in G. goianiense and spatulate in G. paulista (Fig. 4). It differs from G. perplexa in the shape of the tooth which is sharp in G. goianiense and quadrate in G. perplexa , in the shape of the anterior transverse carina (centrally indented in G. goianiense and forming a smooth arc in G. perplexa (Fig. 22)). The color pattern between the three mentioned species (i.e. G. goianiense sp. n., G. paulista sp. n. and G. perplexa) is also clearly different. Etymology. The name refers to the type locality: Goi��s, state of Brazil.
