title: Table 1 in Revealing two centuries of confusion: new insights on nomenclature and systematic position of Argyrogena fasciolata (Shaw, 1802) (auctt.), with description of a new species from India (Reptilia: Squamata: Colubridae)

description: Table 1. Comparison of available characters for the type specimen of C. faciolatus Shaw with other Lycodon species from South and East India. Species from India formerly allocated to the genera Dryocalamus and Dinodon are ignored. Data sourced from Russell (1796), Shaw (1802), Whitaker and Captain (2004), Mukherjee and Bhupathy (2007), Purkayastha (2013), Ganesh and Vogel (2018), Vogel and David (2019), Ganesh et al. (2020, in part), and Kalki et al. (2020). We did not include the character “Supraocular-prefrontal-contact” as used by Ganesh and Vogel (2018) for delimiting Lycodon anamallensis from L. aulicus because it is a consequence of the condition “Preocular-frontal-contact”.
