Diagnosis and comments. This species is closest to S. polybioides , but has a slightly narrower clypeus, more convex propodeum and T1, better defined metanotal crenate band and teeth ridge, F9 less convex ventrally and F11 less flattened.
Description. FEMALE. Differing from S. polybioides in: Color pattern. Supraocular marking elongate, fused with the postocellar marking. Sublateral propodeal marking triangular around an anterior light spot. Mid legs without dark areas and those on hind leg reduced. T1 with a thin black band over the transverse carina.
Measurements and proportions. Body length 12.5 mm. Wing length 12.7 mm. Clypeus 1.2 × wider than high and with its apical margin 1.3 × wider than the interantennal distance. T1 1.34 × longer than broad. S1 1.3 × wider than its medial length and 1.06 × broader than its total length.
Structure. Parategula digitiform and curved, almost right angled. Metanotal ridge more defined. Propodeum more convex, especially in dorsal view. Apical propodeal lamella as developed as de valvula. Surface of the anterior declivity of T1 definitely convex.
Tegumental sculpture. Metanotum rather coarsely macropunctate than striatopunctate and with a better defined and more regularly thick crenate anterior band. Mesepisternum covered with coarser macropunctures. Propodeal striae slightly more transverse, especially in posterior view. S1 with a series of concentric U-shaped striae.
Pilosity. A little thinner overall.
MALE. Differing from the female in: Color pattern. Discussed under variation.
Measurements and proportions. Body length 11.5 mm. Wing length 12.7 mm. Clypeus 1.19 × wider than high and with its apical margin 1.17 × wider than the interantennal distance.
Structure, tegumental sculpture and pilosity. General body shape not much more delicate and head just a bit proportionally smaller than in the female. Clypeus covered with sparse and evident superficial macropunctures. Antennal apex as in S. polybioides , but F9 les concave and F11 sub cylindrical. Mid femur as in S. polybioides . Lateral propodeal surface covered with sparse thin macropunctures.
Variation. The paratypes may differ from the description as follows. Darkening of the scape reduced in the male. Postocellar marking absent. Supraocular marking shorter. Sublateral propodeal marking reduced to a short postspiracular line. Black markings on T1 reduced (with band over carina absent in the male).
Type material. Holotype Ƥ, BRAZIL: Rondônia: Vilhena, 15.x.1986 (C. Elias) [ DZUP]. Paratypes: GUY- ANA: Mazaruni, 25.viii.1937 (O.W. Richards & Smart) [1 Ƥ: MCNV]; BRAZIL: Amazonas: Estrada Manaus-Balbina, Am 240, km 12, Pousada Água Viva, 16.x.2004 (M.L. Oliveira & S.T.P.

Distribution. Guyana and Brazilian Amazonia.
Biology. The holotype seems to have the axillary fossa openings closed by mites. Etymology. Hasyva is a Guarani adjective meaning difficult or painful, indicating my initial difficulties in separating this species from Stenonartonia polybioides .
