(Figs 13, 39, 81, 99, 113, 127, 178)
Diagnosis and comments. This species has an intermediate combination of characters between S. cooperi and the couple formed by S. polybioides and S. hasyva. The absence of scutellar “windows” and the striatopunctate, rather than just striate, propodeal sculpture puts it closer to S. cooperi, but the convex metanotum with a poorly developed crest, the lateral axillary panel not projecting posteriorly, the straight oblique propodeal striae, the narrower proportions of T1 and S1 (and the striate surface of this latter) put S. perdita closer to S. polybioides and S. hasyva. Stenonartonia perdita is peculiar in having the lateral lamella of the scutellum bumped up and with its border upturned.
Description. FEMALE. Similar to S. polybioides, but differing as follows: Color pattern. Antenna without dark markings; frontal mark more lanceolate; supraocular mark broader, fused with the postocellar mark and forming a continuous band with the supraocular and of the other side; humeral mark club-like; propodeum with a short postpiracular line and a submedial thick band or rear-pointing triangle briefly fused with the one of the other side; legs with no dark markings; T1 with anterior declivity yellow and with black anteromedial marking, transverse carina and some subapical suffusion; gradulus of T2 black at sides.
Measurements and proportions. Body length 12.2 mm. Wing length 12.4 mm. Clypeus 1.24 × wider than long and with its apical margin 1.1 × wider than the interantennal distance. T1 1.32 × longer than wide and 0.6 × as wide as T2. S1 1.37 × wider than its medial length and 1.15 × wider than its total length.
Structure. Clypeus with very slight apical depression and its apical margin very slightly concave; scutellum without anterolateral “window”; posterior metapleural border not marked; propodeum convex at side in dorsal view; apical propodeal lamella as developed as the valvula and slightly produced upwards; T1 with upper and lateral surfaces convex as in S. hasyva.
Tegumental sculpture. Clypeus covered with fine and shallow though evident sparse macropunctation; mesepisternum covered with abundant macropunctures nearly as in S. cooperi; metanotal punctation as in S. hasyva; metapleura and propodeal sides covered with a number of well marked fine and sparse macropunctures; propodeal striation as in S. hasyva in direction, but coarsely striatopunctate rather than just striate.
Pilosity as in S. hasyva.
MALE. unknown.
Type material. Holotype Ƥ, BRAZIL: Pará: Serra Norte, Fofoca, 16.ix.1985 (M. Zanuto) [MPEG]. Paratype: BRAZIL: Pará: Floresta Nacional Carajás (STA–col2TA), 4.ii.2010 (A.R. Lima) [1 Ƥ: UFMG].
Distribution. Brazil: Serra dos Carajás in eastern Amazonia.
Etymology. The name perdita means “lost”, refers to the specimens originate from a place separated from the known distribution of other species of Stenonartonia.
