Sagriva is a genus of dinidoridae bugs. It occurs in South and Southeast Asia. Originally described in 1850 from the species Sagriva vittata, no other species were known for over a century, making the genus monotypic for that time. A second species, S. banna, was described in 2017.[1][2]

Description

The genus can be recognised by: head with mandibular plates longer than clypeus and converging in front of it; an angular, transversely directed projection in front of each eye, the eyes subpedunculate; the antennae each with 4 segments and the pedicel and basiflagellum angular in cross section and all faces deeply furrowed between the edges; the pronotum subquadrate in shape with its anterior margin much broader than the head; the wings often reduced (brachypterous); and the lateral margins and posterolateral angles of pregenital abdominal segments without tubercles.[1]

As for the two species within Sagriva, S. vittata is larger (males 15.3–16.7 mm long, females 16.9–19.2 mm) and has a contrasting yellow, brown and black pattern. Sagriva banna is smaller (males 10.8-12.2 mm long, females 14.2–14.3 mm) and uniformly black.[1]

Ecology

Adults and nymphs of S. vittata have been collected from unidentified species of climbing Cucurbitaceae.[1]
