Diagnosis.

Scolia albumtenebris sp. nov. can be distinguished from other Scolia species by the following combination of characters. Females: posterior face of propodeum with scattered punctures (Fig. 5 A View Figure 5 ); body with black setae, metasoma and mesosoma with a mix of black and whitish-yellowish setae (Fig. 6 A View Figure 6 ). Males: posterior face with dense punctures on the sides and scattered punctures in middle (Fig. 5 B View Figure 5 ); head and tergites with black setae (except on the yellow spots), the remaining portion of the body with whitish-yellowish setae (Fig. 6 B View Figure 6 ); paramere forming 90 - degree angle inwards (Fig. 7 E, F View Figure 7 ).

Female description.

Length 16–17 mm (Figs 2 B View Figure 2 , 3 A, B View Figure 3 , 5 A View Figure 5 , 6 A View Figure 6 ).

Head. Clypeus rounded apically, punctate, discal region impunctate and smooth, subapically and lateral edges with dense and coarse punctures. Frons with sparse punctures, denser between the inter-antennal areas. Ocular sinus almost impunctate. Vertex with dense punctures. Edges of clypeus, frons and vertex with short sparse setae. Anterior ocellus with cleft and median fissure.

Mesosoma. Pronotum with fine, dense punctures. Mesoscutum, scutellum and metanotum with sparse punctures. Dorsal area and posterior face of propodeum with sparse punctures. Metasternal plate with tubercle. Mesopleuron with scattered punctures. Metapleuron with scattered punctures on both upper and lower plates. Pronotum, mesoscutum with long dense setae; rest of mesosoma with sparse short setae.

Metasoma. Terga with fine irregular punctures. S 2 with a single median tubercle. Sterna with fine and irregular punctures. T 1 – T 3 with short sparse setae, mostly abundant in the remaining tergites, long setae apically on tergites. Sterna with long dense setae.

Colouration. Integument black. T 2 – T 3 with a yellow spot on each side. Metanotum with a small yellow spot. Body with black setae, metasoma and mesosoma with a mix of black and whitish-yellowish setae. Wings dark brown with violaceous reflections.

Variations.

Without yellow spot on metanotum in one specimen ( Panamá, Soberanía, Camino Plantación ; 3. viii. 2001; D. Quintero, R. Cambra, A. Santos, L. De Gracia leg.) .

Male description.

Length 16–19 mm (Figs 2 C View Figure 2 , 4 A, B View Figure 4 , 5 B View Figure 5 , 6 B View Figure 6 , 7 E, F View Figure 7 ).

Head. Entirely covered with setae. Clypeus concave apically, punctate, discal region barely punctate. Frons with dense punctures, some denser between the inter-antennal area. Ocular sinus with fine, dense punctures. Vertex with sparse punctures. Margin of anterior ocellus with a median fissure. Edges of clypeus with long, sparse setae, frons, ocular sinus and vertex with short, sparse setae.

Mesosoma. Pronotum with dense punctures. Mesoscutum, scutellum and metanotum with sparse punctures. Dorsal area of propodeum with sparse punctures, posterior face with dense punctures on the margins and scattered punctures in the middle zone. Metasternal plate with tubercle. Mesopleuron with scattered punctures. Upper plate of metapleuron with sparse punctures, lower plate of metapleuron smooth. Scutellum, metanotum and propodeum with sparse short setae; rest of mesosoma with long dense setae.

Metasoma. Terga with fine irregular punctures. S 2 with a single median tubercle. S 1 – S 7 with fine and irregular punctures. T 1 – T 3 with short sparse setae, mostly abundant in the remaining tergites, long setae apically on tergites. S 1 – S 3 with long dense setae, mostly abundant and long in the remaining sternites.

Genitalia. Paramere strongly truncated, almost forming a right-angle inwards; in ventral view, bearing a row of setae, starting at inferior edge and extending along lateral edges with sparse long coarse setae; discal and apical region without setae; in dorsal view, with sparse coarse setae. Ventral view lamina volsellaris with sparse and long setae, longer apically, external edge with a dense group of sensory cones. Ventral view of cuspis volsellaris bearing sparse and long setae and with sensory cones apically on external edge.

Colouration. Integument black. T 2 – T 3 with a yellow spot on each side. Head, pronotum, mesoscutum, scutellum and tergites bearing black setae (except on the yellow markings on T 2 – T 3 and metanotum, which are whitish-yellow), the remaining portion of the body with whitish-yellow setae. Wings dark brown with violaceous reflections; costal margin of fore-wing darker.

Etymology.

The name refers to the distinctive white and dark mixed setae. From “ album ” (Latin for “ white ”) and “ tenebris ” (Latin for “ dark ”).

Distribution.

Panama ( Darién, Panamá, Panamá Oeste) (Fig. 9 View Figure 9 ).
