Repository. The specimens are deposited in the National Zoological Collection, Hemiptera Section , Zoological Survey of India, New Alipore, Kolkata, West Bengal, India.

Diagnosis. Body length of apterous male 10.57–12.33, apterous female 10.89–11.90. Males of this species can be distinguished by the presence of a medium sized dense black setal tuft on the anterolateral region of the lateral process of the pygophore (Fig. 3C); the proctiger is posteromedially produced, but the projection is not basally angulated (Figs. 3A, C, J); the setal fringe on the mid femur extends to near the base (Fig. 3G). Females can be identified by the connexival process slightly curved in lateral view and about as long as or slightly shorter or slightly exceeding the lateral process of seventh abdominal sternum (Figs. 3B, E, F, I) and the presence of a short setal fringe on the flexor sub-basal region of the hind femur (Fig. 3H).

Distribution. India: Arunachal Pradesh, Himachal Pradesh, Sikkim, Uttarakhand and West Bengal ( Thirumalai 2002, Saha & Bal 2010) see Fig. 7A View FIGURES 7 . Elsewhere: Nepal ( Hungerford & Matsuda 1965).

Remarks. Records of P. laticaudata from peninsular India (Hardwicke 1823) instead belong to P. agriodes Schmidt, 1926 ; for more information see remarks under P. agriodes . Ptilomera laticaudata recorded from Meghalaya by Bal & Basu (1998) and Lyngdoh (2011, 2013) must be considered as P. assamensis and the P. assamensis recorded from Darjeeling and Jalpaiguri districts of West Bengal by Basu et al. (2016) is considered here as P. laticaudata . These misidentifications are due to the erroneous illustrations of female P. assamensis given in Hungerford and Matsuda (1965). This error was first noticed by Zettel (2003) while studying the type specimens of P. assamensis and describing P. occidentalis Zettel from Bhimtal, Uttarakhand, India. The records of P. laticaudata from Bankura and Bardhaman districts of West Bengal by Bal & Basu (1994) are doubtful because these areas are the part of peninsular India; thus, there is a possibility of the occurrence of P. agriodes in these regions and not P. laticaudata since it is a member of the Himalayan fauna. In the distribution map of P. laticaudata ( Fig. 7A View FIGURES 7 ), these two localities are not given.
