Grotea paulista Herrera-Flórez sp. n..

(Figs 2–5)

Material examined. Holotype: female, BRASIL., SP-Pq. Est. de Intervales Base Barra Gde-Trilha da Anta , Armadilha Malaise Ponto T 10-13-XII.2000 M.T. Tavares e eq. Col. ( DCBU).

Diagnosis. Head in dorsal view with gena flat, not concave; genal tooth spatulate ( Fig.4 ); propodeum with anterior transverse carina centrally indented.

Description. Female.

Head. Head in dorsal view with gena behind eyes flat, not concave; occipital carina slightly raised; posterior ocellus separated from eye by 1.3× its own maximum diameter; postgenal process present, laterally distinct (gena with ventroposterior angle modified to form a conspicuous spatulate or ellipsoid tooth) ( Fig.4 ); antenna with 49 flagellomeres; flagellomere I 1.1× as long as flagellomeres II and III combined.

Mesosoma. Mesosoma 3.4 mm; mesoscutum smooth with sparse setiferous punctures; scutellum in profile strongly convex; propodeum with area basalis about 3.4× as long as broad; anterior transverse carina indented centrally, thus not forming a smooth arc from side to side; pleural carina present ( Fig.3 ); posterior transverse carina, centrally absent; lateral longitudinal carina anteriorly absent; area spiracularis enclosed, posteriorly and laterally, though mesally not separated from area externa; area lateralis rectangular and enclosed, about 2.5× as long as broad, with posterolateral corner at right angle close to lobe surrounding coxal insertion. Fore wing 7.8 mm long, hind wing 5.1 mm. Mesosoma equal to length of tergite I.

Metasoma. Tergite I 3.3 mm; metasoma with tergite I exceptionally slender, about as long as mesosoma from pronotal collar to posterior margin of propodeum. Ovipositor 3.4 mm, hind tibia 2.3 mm.; visible part of ovipositor 1.5× as long as posterior tibia.

Coloration (Fig. 2). Head mostly yellow: apex of mandibles, frons, interocellar area and most of upper part of gena black; a median orange spot on the gena; ocelli yellow; antenna mostly black, scape yellow ventrally. Mesosoma mostly orange: pronotum anteriorly and a small spot posteriorly, scutellum and dorsellum yellow. Fore coxa, trochanter and trochantellus yellow; femur mostly yellow, outer side brown; tibia mostly yellow, brown in a dorsal ring on the base, and in part of the ventral face; tarsus infuscate (dark yellow or brown). Mid coxa mostly yellow with two brown weak stripes; trochanter mostly brown (the rest yellow); trochantellus yellow; femur mostly yellow, outer face (side) brown; midtibia similar in color to foretibia; tarsomere 1 mostly brown (the rest yellow); tarsomeres 2-4 mostly yellow with weak brown spots; tarsomere 5 brown. Hind coxa mostly brown, basally (on the dorsal side) and distally yellow; trochanter mostly dark brown, dorsal side distally yellow; trochantellus yellow; femur mostly dark orange, distally yellow; tibia mostly brown, dorsal side distally yellow; tarsi brown. Wings hyaline with pterostigma black. Metasoma mostly black, tergite I, yellow midway from the posterior margin and with a yellow triangular spot at the posterior margin; tergite II-V with similar triangular yellow spots; tergites VI-VII with yellow posterior strips and laterotergites VI-VIII partly yellow. Ovipositor sheaths black.

Remarks. Grotea paulista sp. n. most closely resembles G. goianiense sp. n. and G. perplexa . The species can be separated as follows: genal tooth spatulate in G. paulista ( Fig. 4 ) and sharp in G. goianiense and gena forming a conspicuous tooth in G. paulista ( Fig. 4 ) but is inconspicuous in G. perplexa . As well, the anterior transverse carina is centrally indented in G. paulista and forms a smooth arc in G. perplexa ( Fig. 22 ). The color pattern between the three mentioned species (i.e. G. paulista sp. n., G. goianiense sp. n., and G. perplexa ) is also clearly different.

Etymology. The name refers to the type locality: São Paulo, state of Brazil.
