Material examined.

Holotype - female. ( DCBU 51038) "Manaus, AM, Brasil, Reserva Km 41, trilha, 24-25-XI-2004, S03°05'07", W60°02'4.92", Armadilha Malaise suspensa, R.B.Q. Silva col."

Description of holotype.

Body length: 4.5 mm. Fore wing length: 3.2 mm

Head. Antenna with 34 segments, whitish setose, length of third segment equal to fourth, length of third, fourth and penultimate segments 3.0, 3.0 and 1.5 times their width, respectively. Maxillary palp with 5 segments and its length 0.5 times height of head. Length of eye in dorsal view 2.1 times temple. OOL: diameter of ocellus: POL = 25:12.5:15. Head completely smooth, with long whitish setae on lateral parts of face, length of malar space 1.5 times basal width of mandible.

Mesosoma. Whitish setose, length of mesosoma 2.0 times its height. Propleuron sparsely punctate. Pronotum smooth, but apical and dorsal sides finely punctate. Mesopleuron smooth, with precoxal sulcus smooth. Mesonotum smooth, with notauli smooth, crenulate anteriorly with apical third joining. Scutellum smooth. Propodeum smooth with large propodeal areola medially.

Fore wing. Infuscate, hyaline apically, length of pterostigma: R1 = 40:70, 1-CU1:2-CU1 = 2:13.

Hind wing. Hyaline, vein CUb present as a very short stub. Vein 1M normal.

Legs. All legs smooth, length of femur, tibia and basitarsus of hind leg 5.0, 10.0, 6.0 times their width, respectively. Length of hind spur 0.5 times length of hind basitarsus.

Metasoma. All terga completely smooth, T1 1.2 times as long as its apical width. Length of ovipositor about 1.4 times fore wing.

Colour. Black, except pedicellus and base of scape dark brown; mandibles, maxillary and labial palps yellowish; fore and mid legs dark brown, hind leg dark brown with femur orange brownish and tibial spurs yellowish. Tegula brownish. Metasoma ventrally yellowish, ovipositor sheath dark brown.

Diagnosis.

This species is closely related to Plesiocoelus bassiformis  but it differs by the anteriorly crenulate notauli, the completely smooth precoxal sulcus, the larger propodeal areola (covering most of the length of the propodeum) and the longer ovipositor sheath (about 1.4 times fore wing).

Etymology.

This species is named after the large propodeal areola.

Biology.

Unknown.

Distribution.

Only known from the type locality in Brazil.
