India: Arunachal Pradesh, Himachal Pradesh, Sikkim, Uttarakhand, West Bengal. Elsewhere: Bhutan.</p> <p>Comparative notes. Metrocoris compar is morphologically similar to M. darjeelingensis Basu, Polhemus &amp; Subramanian, 2016, by having a similar yellowish-brown mark on the mediolateral region of the mesosternum. However, M. compar differs from the latter species by the spatulate apex of the paramere in lateral view (Figs. 1K, M–O, Q), which is bulbous in M. darjeelingensis. The setal fringe on the female hind trochanter of M. compar is pronounced basally (Figs. 1B, H, I), whereas it is pronounced apically in M. darjeelingensis (see Fig. 60 of Basu et al. 2016).</p> <p>Remarks. den Boer (1965) studied the syntypes of M. compar (White, 1883) and designated a specimen figured by White (1883) as the lectotype and the other specimens as paralectotypes and figured the endosomal structure. The endosomal sclerites (Fig. 1R) of the male specimen of the present study from the Neora Valley National Park, Kalimpong District, West Bengal, the type locality of M. dinendrai Basu, Polhemus &amp; Subramanian, 2016, completely matches the illustration given by den Boer 1965 (see Fig. 29). Chen &amp; Nieser (1993 b) studied the paralectotypes of M. compar and specimens from Sikkim, West Bengal, Uttarakhand, Bhutan and Myanmar. The illustration of the endosomal sclerites of M. compar given by Chen &amp; Nieser (1993 b) does not match the illustration given by den Boer (1965). Chen &amp; Nieser (1993 b) and Basu et al. (2016) overlooked the illustration of the endosoma of M. compar given by den Boer (1965) that clearly shows there are some cryptic species of M. compar occurring in the Himalayan region. Moreover, species such as M. darjeelingensis, M. issaci sp. nov. and M. josephi sp. nov. exist in northeast India and have a little morphological differences with M. compar. Hence the characteristics of M. dinendrai completely match those of M. compar given in the revisionary work of den Boer (1965); thus, we synonymize M. dinendrai Basu, Polhemus &amp; Subramanian, 2016 under M. compar. The materials studied by Chen &amp; Nieser (1993 b) should be re-examined and new species described since the illustration of M. compar given by Chen &amp; Nieser (1993 b) is entirely different from that of den Boer (1965). The distribution of M. compar south of Brahmaputra River particularly in Myanmar is doubtful because M. compar is a Himalayan species distributed in Arunachal Pradesh, Himachal Pradesh, Sikkim, Uttarakhand, West Bengal and Bhutan. So the present study excluded its distribution from Myanmar. The specimen studied by den Boer (1965) from Mishmi Hills of Arunachal Pradesh located east to Brahmaputra River belongs to another species. Chen &amp; Nieser (1993 b) also mentioned that specimens of M. compar from Myanmar have the hind femora longer than the mid femora and have a less darkened thoracic venter. Thus, it is evident that M. compar from Myanmar is not conspecific with the species from India. A thorough study of M. compar from the Himalayan region is needed since there would be possibilities of the occurrence of cryptic species.</p> </div>	http://treatment.plazi.org/id/03926975FFB60839FF14FA86BD70F9D4	Public Domain	No known copyright restrictions apply.

Presently known only from East Khasi Hills, Meghalaya, India.</p> <p>Comparative notes. Metrocoris issaci sp. nov. shares the characteristics like the presence of the setal fringe on the base of the flexor region of the hind femur of the female (Fig. 2I) and the falciform male paramere, having the convex area on the dorsal region near middle (Fig. 2N) and the reflex angled process on the proximal region of the dorsal sclerite and the long ventral sclerite surpassing the proximal region of the dorsal sclerite (Fig. 2O) with M. coxalis, M. nigriventris Tran &amp; Polhemus, 2017 and M. josephi sp. nov. The new species differs from M. coxalis and M. nigriventris, by the presence of long processes on both the coxa and the trochanter of the hind leg of the female; in M. coxalis the process is present only on the hind coxa of the female and in M. nigriventris the hind coxal process is absent and the hind trochanter is slightly produced. Metrocoris issaci sp. nov. and M. josephi sp. nov. have processes on both the coxa and the trochanter of the hind leg of the female (Figs. 2B, I; 3C, J); however, these processes are longer in M. issaci sp. nov. (Fig. 2I) when compared to M. josephi sp. nov. (Fig. 3J). Moreover, the area surrounding the omphalium is black in M. issaci sp. nov. (Figs. 2C, H) but it is yellow in M. josephi sp. nov. (Figs. 3B, I). The overall structure of the male paramere is almost similar in M. coxalis, M. issaci sp. nov., M. josephi sp. nov. and M. nigriventris; however, there are distinct differences on the tip of the paramere in each species, in M. issaci sp. nov. it is subapically excavated both the dorsal and the ventral region (Fig. 2N), in M. josephi sp. nov. the excavation is present subapically only on the ventral region (Fig. 3N), in M. nigriventris it is subapically produced and in M. coxalis the paramere is apically bent outwards.</p> </div>	http://treatment.plazi.org/id/03926975FFB20835FF14FE6EBC4AFEB8	Public Domain	No known copyright restrictions apply.

The venter of the meso- and metasterna is black, the anteromedian region of the mesosternum sometimes with a yellow mark; the sublateral black stripes of the mesonotum are very broad (Chen &amp; Nieser 1993a, Fig. 11); the male fore femur is slender, the flexor region medially without notch but apically with a small depression (Chen &amp; Nieser 1993 b, Fig. 180); the paramere is falciform (Chen &amp; Nieser 1993 b, Fig. 191); the ventral sclerite of the endosoma is surpassing well beyond the dorsal sclerite in lateral view (den Boer 1965, Fig. 35); the sternum VII of the female is constricted laterally and is completely covering the genital segments.</p> <p>Included Species: Metrocoris nepalensis and M. sikkimensis Basu, Chandra and Venkatesan, 2018.</p> <p>Distribution. Bhutan, India (N, NE), Nepal.</p> <p>Remarks. Chen &amp; Nieser 1993 b noted that the lateral sclerites are indistinct and in the illustration of the endosoma of M. nepalensis the first pair of the lateral sclerites are missing and a small accessory sclerite is present (Chen &amp; Nieser 1993 b, Fig. 199); however, both the pairs of the endosomal sclerites are present and the apical accessary sclerite is absent as per den Boer (1965) (see Figs. 34, 35). So a careful study of type materials or materials from type locality would help in the better understanding of the characteristics of M. nepalensis. The correct spelling of the place ‘Soondrijal’ mentioned in den Boer 1965 is Sundarijal located in the Kathmandu District of Nepal.</p> </div>	http://treatment.plazi.org/id/03926975FFB90833FF14FE6EBA2EFBCC	Public Domain	No known copyright restrictions apply.
