Material examined

Holotype, female ( ICAR / NBAIR /P4911), INDIA: Karnataka: Mandya, 12.521°N, 76.895°E, ca 740 m, YPT, in finger millet ( Eleusine coracana : Poaceae ) field, 29 May 2016; Paratypes: one male ( ICAR / NBAIR /P4989), Andaman and Nicobar Islands: Little Andaman, Hut Bay, 10.587°N, 92.562°E, ca 40 m, SN, 26 March 2016; one male ( ICAR / NBAIR /P4990), Karnataka: Mandya, 12.521°N, 76.895°E, ca 740 m, YPT, 19 March 2016.

Etymology

The specific name ‘peludo’ in Spanish means hairy, referring to the densely setose metapleuron. The name is treated as an adjective.

Diagnosis

Hadronotus peludo sp. n. is similar to H. westeberhardae sp. n. but differs from it in the following character states: In H. peludo setae on metapleuron are sparse and longitudinal costae on T2 are unevenly distributed, while in H. westeberhardae setae on metapleuron are dense and T2 with evenly distributed longitudinal costae.
