Parasyscia keralensis

Bharti & Akbar (2013): Cerapachys keralensis Karmaly, 2012 described on the basis of two minor? workers collected from the Palakkad district of Kerala. The new species is highly dubious. The description is minimal, superficial and contains no comparative notes. The photographs are derisory as illustrations supporting the inadequate descriptions. Cerapachys keralensis Karmaly, 2012 is here considered to be a species inquirenda.

Identification
Karmaly et al. (2012) - Cerapachys keralensis closely resembles to Cerapachys rissi (=Cerapachys sulcinodis) in following features: 1. Antennae 12 jointed., 2. The constriction between basal two segments of abdomen very deep, 3. Head, thorax, abdomen black, shiny; Mandibles, clypeus, antennae, legs reddish yellow. However Cerapachys keralensis differs from Cerapachys rissi in having: 1. Abdomen punctured (in Cerapachys rissiabdomen smooth)., 2. Pedicel with projection beneath (In Cerapachys rissi pedicel without projection beneath)., 3. Whole body covered with whitish hairs (in Cerapachys rissi whole body covered with yellowish hairs).
