E-mail. jimmypaul88@gmail.com Abstract The monotypic velvet ant-mimicking spider genus Coenoptychus Simon, 1885 is revised. The paper provides the first de- tailed morphological and genitalic description, with the first description and illustrations of the male of the type species, Coenoptychus pulcher Simon, 1885, and a redescription of its female. Two new combinations are proposed: Coenoptychus mutillicus (Haddad, 2004) comb. nov. and Coenoptychus tropicalis (Haddad, 2004) comb. nov.; both species were previ- ously included in Graptartia Simon, 1896. The distribution records of the genus are updated. Key words: mimicry, Parambikulam Tiger Reserve, redescription, taxonomy, transfer, wasp mimicking Introduction Coenoptychus Simon, 1885 is a monotypic spider genus originally described based on an unspecified number of female specimen(s) collected from Ramnad (now known as Ramanathapuram) in the Tamil Nadu State of southern India (Gravely 1931). The genus is known from Sri Lanka too (Karsch 1892; Gravely 1931; Green 1912; Deeleman-Reinhold 2001). Together with Graptartia Simon, 1896 (Haddad 2004), Coenoptychus are unique among castianeirines in their resemblance of mutillid wasps (Karsch 1892; Green 1912; Berland 1932; Deeleman- Reinhold 2001). Despite several records, the genus and its type species, Coenoptychus pulcher Simon, 1885, are poorly described and illustrated (Simon 1885; Karsch 1892; Green 1912; Gravely 1931; Majumder & Tikader 1991; Deeleman-Reinhold 2001). Although the male of C. pulcher is known (Green 1912), its palp has never been illustrated, leaving the identity of males of this species, as well as the genus, obscure. In this paper, we redescribe C. pulcher based on fresh materials collected from the Kerala state of southern India, and propose the transfer of G. mutillica Haddad, 2004 and G. tropicalis Haddad, 2004 to Coenoptychus. Additionally, the current distribution of the genus is mapped. Material and methods The specimens were preserved in 70% ethanol and studied under a LEICA S8AP0 stereomicroscope. All measurements are in millimetres (mm). Lengths of palp and leg segments are given as: total (femur, patella, tibia, metatarsus, tarsus), except metatarsus absent from the palp. Spine positions follow the format of Bosselaers & Jocqué (2000). The images of preserved specimens were taken with a Leica DMC 2900 digital camera attached to a Leica M205 A stereomicroscope, with the software package Leica Application Suite (LAS, version 4.5.0) for stacking images taken at different focal planes. Field photos were taken with Canon EOS 6D with Canon MP-E 65mm Macro photo lens. The specimens are deposited in a reference collection housed at the Division of Arachnology, Department of Zoology, Sacred Heart College, Thevara, Cochin, Kerala, India (ADSH).
