Two new species of Scymnini (Coleoptera: Coccinellidae) from Karnataka, India.

Poorani J - Biodivers Data J (2015)

Bottom Line: As a result, many economically important species remain poorly characterized, or worse, unnamed.These species are externally similar to other known species and often misidentified.Horniolussororius sp. n. and Scymnus (Pullus) rajeshwariae sp. n. (Coleoptera: Coccinellidae) are described here and illustrated with notes on their biology and related species.

ABSTRACT

Background: The Scymnini (Coleoptera: Coccinellidae) of the Indian region is rich and highly speciose, with nearly 90 described species and scores of undescribed species (Poorani 2002). There is a dire need to systematically revise the genera and species of this tribe from the Indian region. Due to paucity of representative collections covering the entire region and lack of access to types, it is difficult to identify most of the Scymnini of the Indian region to species. As a result, many economically important species remain poorly characterized, or worse, unnamed.

New information: Two economically important and unique species of Scymnini (Coccinellidae) belonging to Horniolus Weise (1900) and Scymnus (Pullus) Mulsant (1846) from the Southern Indian state of Karnataka that have remained unnamed for long are treated in this paper. These species are externally similar to other known species and often misidentified. Horniolussororius sp. n. and Scymnus (Pullus) rajeshwariae sp. n. (Coleoptera: Coccinellidae) are described here and illustrated with notes on their biology and related species.

Figure 1522416: Male genitalia: Penis apex

Mentions: Length: 2.20-2.65 mm; width: 1.65–1.80 mm. Male: Body (Fig. 3) elongate oval, moderately convex. Head and pronotum testaceous to dark brown, elytra dark brown with four yellowish spots – first pair transverse, roughly quadrate, located before middle in anterior half, second pair smaller, transverse, located around 4/5th of elytra, both spots occasionally larger, almost touching lateral margins of elytra; head with elongate silvery white hairs, pronotum with yellowish white to brownish pubescence, elytra with a mixture of dark brown and yellowish white hairs, those on elytral spots paler, those on rest of elytra predominantly brown to black. Ventral side more or less uniform reddish brown, pro-, meso- and metasternites darker reddish brown, tarsi of legs slightly lighter, yellowish brown. Head with clypeal margin carinate, punctures separated by 2-3 diameters, denser and separated by less than their own diameter near eye margins. Pronotum densely punctate on posterior and lateral margins, slightly more widely spaced on disc, separated by 3-5 diameters. Elytral punctures denser and slightly larger than those on pronotum, separated by 2-5 diameters on disc, punctures on lateral sides and apices more closely spaced. Prosternal process with an inverted Y-shaped carina. Abdominal postcoxal line (Fig. 4a) complete and semicircular, area enclosed by postcoxal line sparsely punctate with few punctures along anterior margins. Ventrite 5 truncate, ventrite 6 barely emarginate. Tarsi trimerous. Male genitalia (Fig. 4b, c, d, e) with tegmen in ventral view (Fig. 4b, c) with penis guide shorter than parameres, apically very slightly asymmetrical, broadest at base, progressively narrowed to apex, apical one-fifth triangular; parameres longer than penis guide, apices with elongate hairs. Penis capsule (Fig. 4d) with a prominent inner arm, outer arm lacking; apex of penis (Fig. 4e) strongly flattened or spatulate, densely spotted. Female: Similar to male. Ventrite 6 apically weakly arcuate. Genitalia with spermatheca (Fig. 4f) with spermatheca tubular, long and intricately coiled, sperm duct elongate and progressively broader.
