Sculpture of orbital furrow: foveate. Inner orbits in frontal view: almost parallel to each other. Central keel on frons: present, extending 0.1× the length of frontal depression. Malar sulcus: with shallow rectangular depressions. Shape of frontal depression: ovoid. L: W of frontal depression: 26.3: 24.4. Width of frontal depression: 0.7× IOS. Sculpture of frontal depression: transversely carinate; space between carinae medially smooth, laterally weakly foveolate. Submedian carina of frontal depression: restricted to dorsal 1/3. AOD in dorsal view: 5.5× OOL. Sculpture of frons sans frontal depression: polygonal cells with rugose sculpture, setose. Sculpture of vertex: polygonal cells, setose. Hyperoccipital carina: present. Sculpture of gena: polygonal cells.

Mesosoma. L: W of mesoscutum: 25.1: 38.9. Sculpture of mesoscutum: anteriorly with polygonal cells and posteriorly interspersed with longitudinal carinae; densely setose. Scutoscutellar sulcus: foveate. L: W of mesoscutellum: 14.0: 28.0. Sculpture of mesoscutellum: longitudinally carinate interspersed with polygonal cells, densely setose laterally. Posterior mesoscutellar sulcus: foveate. Sculpture of metascutellum: foveate, projecting posteromedially. Posterior margin of metascutellum: weakly concave. Sculpture of metanotal trough: foveate. Lateral propodeal area: laterally wide, narrowing centrad. Sculpture of lateral propodeal area: with depressions. Posterior propodeal projection: short, pointed posteriorly. Pronotal cervical sulcus: with depressions. Sculpture of lateral pronotal area: dorsally foveate, medially transversely carinate with depressions between carinae, ventrally weakly reticulate. Prespecular sulcus: with transverse foveae. Sculpture of speculum: transversely carinate. Femoral depression: dorsally transversely carinate and ventrally with uneven foveae. Episternal sulcus: foveate. Postacetabular sulcus: foveate. Mesepimeral sulcus: foveate ventrally. Sculpture of posterior mesepimeral area: with intricate sculpture. Mesopleural carina: indicated ventrally. Mesopleural pit: present. Metapleural sulcus: with large depressions. Sculpture of dorsal metapleural area: foveate, sparsely setose. Sculpture of ventral metapleural area: with a transverse carina and rugose sculpture, very sparsely setose. Paracoxal sulcus: with large depressions. L: W of fore wing: 100.2: 47.3. Ratio of length of m: st: pm: 3.0: 8.3: 2.3. Shape of submarginalis: straight and adjacent to anterior margin of wing in basal 3/5, then dips before reaching marginalis.

Metasoma. L: W of metasoma: 52.7: 43.9, 1.2× as long as wide. Anterior margin of T1: medially and laterally with a weak projection. Basal foveae on T1: present. Sculpture of T1: longitudinally costate, space between costae weakly rugose; posteromedially smooth. Sculpture of T2: anteromedially with elongate cells with smooth areas; sublaterally and laterally with longitudinal costae on anterior margin, extending half length of tergite; remainder of tergite with even reticulations; basal foveae absent. Length of T2: 5.3× length of T3. Sculpture of T3–T4: anteriorly finely punctate, medially rugose and posteriorly smooth. Setation of metasoma: laterally and posteriorly densely setose.

Material examined

Holotype, female ( ICAR / NBAIR / P4829 ), INDIA: Karnataka: Bengaluru, Jarakabande Kaval , 13.124°N, 77.548°E, ca 920 m, MT, 23 January 2015.

Etymology

The specific name ‘stupa’ refers to the arched submedian carina of the frontal depression which resembles the hemispherical stupas or reliquaries containing the remains of Buddhist monks and nuns or artefacts associated with them. The name is treated as an adjective.

Diagnosis

Hadronotus stupa sp. n. is similar to H. taraka sp. n. but differs from it in the following character states: In H. stupa central keel is short, at most 0.1× length of frontal depression and mesoscutum and mesoscutellum with longitudinal carinae, while in H. taraka central keel is half the length of frontal depression and mesoscutum and mesoscutellum are without longitudinal carinae.
