Abstract: Cardiohypnus spatulatus (Vats & Chauhan, 1993) SDI comb. nov. Horistonotus spatulatus Vats & Chauhan, 1993: 37 (original description; published type locality: Chail, India; another locality- India: Jammu & Kashmir, Uttarakhand); Cate, 2007: 208 (considered as Erroneous Assignment; classified under Negastriinae incertae sedis; catalogue; “HP” as India: Himachal Pradesh; “KA” as India: Kashmir; “UP” as India: Uttaranchal, Uttar Pradesh). Type Locality. India: Chail, Solan District, Himachal Pradesh. Type Depository. Holotype, M (??); Allotype, F (??); 95 Paratypes, 42 M, 53 F (??). Distribution in India. Himachal Pradesh (Kinnaur District, Kullu District, Mandi District, Solan District), Jammu & Kashmir (Doda District), Uttarakhand (Champawat District, Pithoragarh District, Rudraprayag District). General Distribution. India. Remark. The type material for Horistonotus spatulatus is not deposited in FRID and may be housed in IARI; however, verification was not possible. As the presence of this species in Uttar Pradesh requires confirmation, this locality is not included here. Vats & Chauhan (1993: 37) described Horistonotus spatulatus with morphological characters and an aedeagus structure that do not support its placement in the American genus Horistonotus (Douglas 2017). Based on the original description and illustration of the aedeagus (Vats & Chauhan 1993: 37–38, Fig. 6), the species is herein transferred to the genus Cardiohypnus, and we propose Cardiohypnus spatulatus (Vats & Chauhan, 1993) comb. nov. Morphologically, this species is closely related to Cardiohypnus mirabilis (Candèze, 1860) and Cardiohypnus brancucci Dolin, 1992. C. spatulatus is considered endemic to India.
