Monatractides angulatus (Walter, 1928)

Records from the study area: West Bengal, Punjab—“ Atractides angulata “ Walter (1928); “ Torrenticola angulatus “ Prasad (1974).

Material compared: NHMB: 3302 Atractides angulatus Walter, Ƥ, labelled as " Typus " XX/89, Vorder-Indien, coll. Chappuis; 3304 Atractides angulatus Walter, Ƥ, Dardjiling ?, coll. Chappuis? XX/X/18.

Remarks: This species belongs to the Monatractides macroporus (K. Viets, 1935) species-complex, characterized by the presence of an anteriorly slender and elongated Cx-1, a relatively short medial suture line of Cx-2+ 3 in both sexes, and a narrower capitular bay (for a discussion on the M. macroporus speciescomplex, see Pešić & Smit 2009b). Monatractides angulatus is known from a single female specimen, and differs in the shape of capitular bay which proximal end is rectangular (Lundblad 1969). However, at the present state of knowledge, females of this species-complex cannot be identified. Understanding the taxonomic position of this is not possible without finding male and additional material from the locus typicus area.

Habitat: Mountain streams.

Distribution: India.
