Type. Rhene haldanei Gajbe, 2004 : Holotype ♀ (NZC-ZSI) from INDIA, Madhya Pradesh, Jabalpur, Tilwaraghat , 07.08.1998, leg. P. Gajbe.

Comments. Rhene haldanei Gajbe, 2004 was described based on a holotype female from Jabalpur, Madhya Pradesh. Detailed examination of the holotype revealed it to be identical to Bianor angulosus in both general colour pattern and genital morphology. The abdominal pattern with a pair of white spots in the posterior half and median chevron shaped markings; epigyne with a well-developed central pocket and fossae; copulatory openings leading to funnel-shaped inlets; copulatory ducts long with clearly visible first loop and spermathecae elongated (cf. Figs 65–70 with figs 7, 11 in Zabka (1985) and figs 53, 55, 61 in Logunov (2001)). Thus, the species R. haldanei is to be treated as a member of Bianor and a junior synonym of B. angulosus .

Distribution. India (Assam, Bihar, Himachal Pradesh, Karnataka, Odisha, Punjab, West Bengal (Caleb, 2019), Kerala ( Babu et al., 2021), Madhya Pradesh (present study)), Sri Lanka, Bhutan, Bangladesh, China, Taiwan, Myanmar, Vietnam, Thailand, Malaysia, Indonesia ( WSC, 2022) ( Fig. 72 ).
