Naddia tangi sp. nov.

( Fig. 2 View FIGURE 2 )

Type series. Holotype: 1 male, Coll. R. I. Sc. N. B. / South India / S. Coorg. Ammattl / 3100 ft. V-1951 / P. S. Nathan ( RBINS).

Diagnosis. Head and pronotum entirely covered with golden setae. Pronotum with sharp anterior angles. Pronotal hypomeron setose. Elytra red-orange. Tergites 3, 7 and 8 entirely covered with golden setae. Male sternite 7 with an arc-shaped cluster of setae in the middle.

Description. FL: 12.32 mm; WL: 24.22 mm. Head and pronotum black, densely covered with golden setae. Antennae dark brown, short and stout. Pronotum with sharp anterior angles. Pronotal hypomeron setose. Elytra red-orange. Tergites primarily dark brown. Tergite 3 entirely covered with golden setae, extending to paratergites. Tergites 4–6 each with a pair of lateral golden setal patches. Tergites 7–8 entirely covered with golden setae. Sternites 3-8 dark brown. Male sternite 7 with arc-shaped cluster of setae in middle and a shallow sub-triangular emargination at midpoint of posterior margin. Male sternite 8 with a moderately deep sub-triangular emargination at midpoint of posterior margin. Femora and tibiae dark brown. Tarsomeres 1–4 flat and strongly bilobed. Aedeagus slender. Median lobe of aedeagus parallel-sided in parameral view with a slight expansion near rounded apex. Paramere flat and strongly reduced, with six very short setae in central basal area. Apical lobe of median lobe straight in lateral view.

Comparison. This species can be distinguished from all other Naddia besides N. alexeyi sp. nov. by the sharp anterior angles of the pronotum. It can be distinguished from N. alexeyi sp. nov. by: head with golden setae, disc of pronotum without yellow oval setal patches, and a narrower median lobe of the aedeagus. The dorsal habitus of N. tangi sp. nov. resembles N. wielebnowskiae Schillhammer, 1996 , but differs from it by: pronotum with sharp anterior angles, pronotal hypomeron setose, golden setal patches present on tergites 3 and 7.

Distribution. Naddia tangi sp. nov. is known only from its type locality in southwestern India. As a winged species, it likely has a wider distribution.

Etymology. The species is named after Liang Tang, who shows passion for and makes great contributions to the taxonomy of rove beetles.
