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
.
