)
Female. Body length
2.5–3.2 mm
; fore wing length 2.7–3.0 mm
Head
. Smooth and polished, with scattered setae (
Fig. 5
); 1.21–1.27x wider than mesoscutum. Face 1.73– 1.83x broader than long, polished. Clypeus about 2.4x broader than long. Malar space 0.43–0.50x eye height in frontal view. In lateral view, eyes 1.4–1.6x longer than temple. Ocelli small, its maximum width 0.40–0.53x ocellocular distance. Antenna about 1.2x longer than fore wing, 29–32 segmented; first flagellomere about 2.8–3.2x longer than wide.
Mesosoma
. 1.7–1.8x longer than high. Mesonotum 1.26–1.28x longer than width of mesoscutum. Pronotum dorsally crenulated anteriorly and rugose posteriorly, polished and without setae laterally. Mesonotum smooth and polished; scattered setae around mid-pit and laterally at lateral lobes of mesoscutum; notauli present on anterior 0.27–0.35 of the mesoscutum; mid pit long and shallow, 0.63–0.67x the length of mesoscutum; scutellum 1.1x as long as wide, smooth and polished; scutellar sulcus 0.24–0.33x as long as wide, with one median carina and sometimes a pair of weak lateral carina. Mesoscutellar trough strongly costate proximally, distally smooth and bare; metanotum strongly crenulate. Mesopleuron bare on central portion; sternaulus present and crenulated. Epicnemial carina present, incomplete ventrally. Metapleuron weakly rugose, with setae at ventral half. Propodeum smooth and polished; well defined pentagonal areola with distinct cross-bridge and two pairs of transverse lateral carinae (

); median carina short. Hind coxa 1.25–1.31x longer than wide, 0.8–0.9x as long as metasomal TI. Hind basitarsus 0.35–0.41x longer than hind tibia. Hind tarsal claws with tiny basal lobe.
Wings
(
Fig. 41
). Fore wing. Stigma about 3.6x longer than broad; vein r arising from middle of stigma. Vein r 0.55–0.60x longer than vein 3RSa. Vein 2RS straight, about 0.9x longer than 3RSa. Vein 3RSa 0.45–0.48
x 3
RSb and about 1.8x as long as vein r-m. 1Cub 1.6–1.8
x 1
CUa. Vein (RS+M)b short and spectral. Vein 1-1AC spectral, 0.18–0.28x longer than vein 2-1A. Hind wing. Vein M+CU 1.7–1.8x longer than 1M. Vein cu-a 0.58–0.68x as long as 1M. Vein r-m 0.45–0.58x as long as 1M.
Metasoma
. TI 0.84–0.93x as long as apical width; striated medially, otherwise smooth and polished; dorsal carinae complete (reaching apical margin) or nearly so, converging but not meeting posteriorly; dorsope deep and large. TII smooth and polished; remainder metasomal terga very weakly sclerotized. TII 2.3x longer than TIII. Hypopygium short. Ovipositor short and straight, 0.63–0.66x as long as hind tibia; ovipositor sheaths 0.85–0.98x longer than ovipositor.
Color
. Head, propleuron, mesoscutum centrally, prescutellar sulcus, scutellum, and mesopleuron ventrally orange. Antenna, pronotum, remainder mesonotum, and metanotum black. Propodeum, metapleuron, metasomal terga I–III, and most of legs yellowish. Mandibles, palpi, tegula, fore and mid coxa, first metasomal terga light yellow. Mandible apex, mesopleuron centrally, all fifth tarsomeres, apical 1/3 of hind tibia and hind tarsi, remainder metasomal terga and ovipositor sheaths brown.
Male. Similar to female. Body length 2.5–3.0 mm; antenna relatively longer with 27–31 segments. TI slender and TII slightly shorter as compared with TIII.
Biology.
Unknown
Comments.
This new species resembles
A. masoni
in the straight and relatively long ovipositor, and the simple tarsal claws.
Andesipolis atlanticus
sp. n.
and
A. masoni
are distinctly different in the color of propodeum, which is yellow in
A. atlanticus
sp. n.
and brown in
A. masoni
,
as well as the sculpturing of petiole, which is smooth in
A. atlanticus
sp. n.
and mostly rugose in
A. masoni
.
It can be distinguished from the other known species by the regular and well-defined areola on a smooth and polished propodeum.
Distribution.
Found in the Atlantic Forest domain, in high altitude (over
1,500 m
high, but one specimen was captured at
987 m
) mountains of
Rio de Janeiro
and
São Paulo
States. The southernmost distribution is at a medium altitude (
600–900 m
) in the mountains of
Santa Catarina
State.
