Scopoides tikaderi Platnick, 1989 .

Type material. Holotype female from INDIA: Chhattisgarh: Bastar: Hatkachora near Jagadalpur (19 o 04’25.90’’N, 82 o 02’11.86’’E), 555 m alt.; U.A. Gajbe leg.; 2 January 1984; repository NZC-ZSI, Kolkata (5145/18), examined . One allotype male, two males and one subadult female paratype from INDIA: Madhya Pradesh: Tikamgarh: Orchha village (25 o 22’05.77’’N, 78 o 37’42.69’’E), 230 m alt; U.A. Gajbe leg.; 28 December 1983; repository NZC-ZSI, Kolkata (5146/18), examined.

Justification of the transfer. Gajbe (1987) described S. tikaderi based on male and female specimens collected from Chhattisgarh and Madhya Pradesh. The original and subsequent illustrations of the genitalia (Gajbe 1987: figs 3–4, 6; Gajbe 2007: figs 105–106, 108) of this species clearly indicated that it is misplaced within Scopoides . Detailed study of the types of S. tikaderi (Figs 17–18) revealed that this species has resemblance with the features of Megamyrmaekion species as discussed above for Megamyrmaekion pritiae comb. nov.

Remarks. The ‘paratype’ vial (5146/18) contains two males and one subadult female, instead of three male specimens as mentioned in the original description.
