Abstract
A new jumping spider species, Colopsus arkavathi Caleb sp. n., is described from Karnataka, India. A new combination, C. manu (Caleb, Christudhas, Laltanpuii et Chitra, 2014) comb. n. (ex. Hyllus) is proposed; the latter species name is recognized as a senior synonym of C. cinereus Kanesharatnam et Benjamin, 2021 syn.n. A detailed description, illustrations, and a map showing the records of all theknown Indian Colopsus congeners are provided.
KEY WORDS: Aranei, description, Karnataka, Sri Lanka, taxonomy
General appearance of Colopsus arkavathi sp. n., male (1–3) and female (4–6). 1, 4 — dorsal view; 2, 5 — dorso-lateral view; 3, 6 — front view. |
Colopsus arkavathi Caleb sp. n.
DIAGNOSIS. The male of C. arkavathi sp.n. is most
similar to that of C. manu (see below), but can be easily
distinguished by the v-shaped white marking in the ocular
area and three yellowish white clypeal stripes (absent in C.
manu); the palpal tibia as long as wide (longer than wide in
C. manu); RTA with a broad base, protruding laterally and
benting at an obtuse angle with the tip directed apically in
ventral view (gently curved, relatively longer, thorn-like in
C. manu). The female can be distinguished by the broader,
laterally aligned copulatory ducts (cf. Figs 1–3, 15, 16 &
22–24 with Figs 17–21).
ETYMOLOGY. The specific epithet is a noun in apposition taken after the River Arkavathi originating in Nandi Hills. The river has been running dry and polluted due to urbanization and industrialization for almost half a century.
