The genus was earlier considered a synonym of Evarcha Simon, 1902[Prószyński, 1984, but has recently been revalidated based on both morphological and molecular evidence [Kanesharatnam, Benjamin, 2021]. Colopsus was recorded from India with the discovery of C. cinereus Kanesharatnam et Benjamin, 2021[Logunov, 2021a, which was originally described from Sri Lanka [Kanesharatnam, Benjamin, 2021]. While studying salticid specimens from Karnataka, we have found out that they are very similar both to Hyllus manu Caleb, Christudhas, Laltanpuii et Chitra, 2014 known from South India and to C. cinereus known from India and Sri Lanka. In order to establish the identity of the newly collected specimens and C. cinereus, the types of H. manu have been re-examined. Thus, the present paper aims: (1) to describe a new Colopsus species from Karnataka, India, (2) to provide new detailed digital images of H. manu, and (3) to synonymise the name C. cinereus with H. manu.
Materials and methodsSpecimens were hand-collected and preserved in 70% ethanol. Images of live specimens were captured either with an Olympus OM-D E-M1 Mark II camera with 60 mm Zuiko macro lens, or a OnePlus 6T mobile phone attached with SKYVIK 25 mm macro lens or Apexel Professional 12x/24x. Morphological examination was carried out under a Leica SAPO stereomicroscope and photomicrographs were taken with a Leica MC190 HD camera and processed with the Leica Application Suite (LAS) version 4.13. Left male palps were detached and examined in detail and photo-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 the known Indian Colopsus congeners are provided.
