3. Caenohalictus cyanolucens sp. nov.

(Figs. 3D, 8–9, 26C, 29D–F, 31B)

Diagnosis. This species can be separated from other species by the combination of short maxillary palpomeres and obtuse epistomal angle with the mesoscutum and metapostnotum granulate. Another diagnostic feature is the bright metallic blue gena, which contrasts with the rest of the integument (Fig. 8A, 9A). The following features are relevant to species diagnosis: a deep, areolate mesepisternal sulcus and male flagellomeres 2–11 with anterior large patches of placodea sensillae (Fig. 3D).

Goldish green below the antennal sockets and dark turquoise above. Labrum: yellow. Mandible: black; amber apical spot occupying around 1/3 of its length. Maxillary palpomeres length: 0.5–1.0x MOD. Clypeus: punctate to sparsely punctate; coriaceous to areolate; yellow spot occupying around 1/2 of the clypeal area, with a dark edge separating it from the metallic area. Epistomal lobe: angle obtuse and not projected onto the clypeus. Supraclypeal area: coriaceous to areolate; punctate to sparsely punctate. Parocular area: yellow to white plumose, thick and long setae, on the clypeus a little thinner. Antennae: scape black with very weakly blue reflections, sometimes with a few yellow spots; flagellomeres black to yellow anteriorly, except on the last ones, that are dark brown anteriorly, can vary from F7–11 to F10–11, crenulate, F2 longer than each F3– F10, flagellomeres 2–11 with anterior large patches of sensilla placodea. Frons: areolate-rugulose; inconspicuous punctation, blending with the sculpture. Eye setae: 0.7–1.0x MOD. Gena: metallic blue to turquoise; rugose; slightly punctate; sparse, long and thick plumose setae. Mesosoma. Integument color: dark green on the pronotum, mesoscutum, scutellum and metanotum, sometimes with some dark blue tones except on the scutellum; dark blue on the median depression of metapostnotum, on the sides and ventrally of mesosoma. Mesoscutum: punctate to sparsely punctate; granulate-areolate to coriaceous. Scutellum: lineolate to coriaceous; sparsely punctated to very sparsely punctated. Mesepisternum: areolate-rugulose to lineolate. Metanotum: coriaceous; slightly and sparsely punctate. Metepisternum: areolate-rugulose to lineolate. Legs: coxa black with dark bluish green reflections, trochanter and femur black with green reflections, fore leg tibia dark brown to yellow, yellow elsewhere, middle leg tibia dark brown with yellow apex, yellow elsewhere, hind leg tibia black, yellow elsewhere; legs with white to yellow plumose setae. Metapostnotum: median depression occupying most of the dorsal area; striae areolate-rugose; granulate-areolate. Propodeum: with sparse, short and thick plumose setae; pit not carinate, not enclosed above, sometimes weakly. Metasoma. Terga: mostly black, with a few dark green tones, mostly anteriorly; marginal area dark brown. Sterna: S1 dark brown, with dark blue reflections, dark brown elsewhere. Genitalia. Gonobase: wider than long, as long as 2/3 the gonocoxite. Volsella: as long as 1/2 the gonapophysis, as wide as long. Gonapophysis: ventral prong present; dorsal flanges starting almost at the apex, as wide as 2x the gonapophysis length; dorsal outer tooth present; dorsal crest present; dorsal depressions and ridge absent. Gonocoxite: longitudinally striate. Gonostylus: VA long lobe, thicker at the base to the middle, and thinner from the middle to the apex, with small setae on its apex; VP small lobe merged with VA, directed upwards; MGL reniform to arcuated, concave; IGP with a basal setose lobule, with thick and small setae; OGP with 5–6 long branched setae on apex.

Etymology. Cyanolucens is compounded from the Greek cyanos (blue) and the Latin lucens (shining, gleaming), referring to the metallic blue shining gena, which contrasts with the predominantly green integument on the remainder of the body.

Variation. There are a few female specimens that have black integument and sometimes with the blue reflections being almost imperceptible.

Distribution. Brazil: Paraná, Rio Grande do Sul, Santa Catarina, São Paulo.
