Plateros atrosuturalis Kazantsev, 2011: 189 . New name for P. nigrosuturalis Kleine, 1939 because of secondary homonymy with P. nigrosuturalis (Pic, 1921) .

Material examined. Nepal, 1male,“E Nepal, Arun V., Mure-Num, 2200– 1550 m, 4–7.VI.1983, M. Brancucci ” / “ Plateros suturalis Pic ” ( ICM) . India, 1 male, “ India, Distr. Darjeeling, Chim-Khona ( Ghum), 2200 m, 4.VI.1975, W. Wittmer ” / “ Plateros suturalis Pic ” ( ICM) .

Distribution. Eastern Nepal (Arun Valley), northeastern India (Darjeeling), northeastern Myanmar (Kambaiti). First record for Nepal.

Remark. Plateros atrosuturalis closely resembles P. suturalis Pic, 1919 in habitus, differing only in the larger eyes and longer antennae ( Fig. 14, cf. Fig. 10). The two specimens examined from Nepal and Darjeeling were initially identified as P. suturalis . However, an examination of their aedeagi, which are distinctly different from those of P. suturalis , confirmed that the specimens actually belong to P. atrosuturalis (Fig. 28, cf. Fig. 25).

Plateros gavryushini Kazantsev, 2017: 243 .

Type material examined. Holotype of P. gavryushini , Thailand, 1 male, “Thailand, Trat prov., Koh Chang Is., White Sands Beach, env. Khao Inn, 12.10372°N, 102.27498°E, 9.XII.2011, D.I. Gavryushin leg.” ( ICM). GoogleMaps

Remark. Colour photos of the habitus and the aedeagus of P. gavryushini were published by Kazantsev (2017, 2021a).

Melaneros gurkha Kazantsev, 2001: 14 .

Plateros anguliplanatus Kazantsev, 2021: 51 , syn. nov.

Type material examined. Paratype of M. gurkha , India, 1 male, “India, U.P., Gangani , 1250 m, 13–20. VI.1981, M. Brancucci ” ( ICM) .

Additional material examined. Nepal: 3 males, “Nepal, P. Bagmati, D. Chitwan, Sauraha, Hotel Sweet Home, 27°35′10″N, 84°29′29″E, 190 mNN, 05–07. VII.2022, A. Kopetz leg. #22–29” ( ICM and NME) GoogleMaps .

Distribution. Nepal (Birganj, Karnali), northern India ( Uttar Pradesh), southwestern China ( Yunnan), northern Vietnam ( Hoa Binh), northern Thailand ( Chiang Mai), Cambodia.

Remark. Plateros anguliplanatus ( type locality: Cambodia) was not compared with P. gurkha from India ( Uttar Pradesh) and Nepal in the original description (Kazantsev, 2021). The comparison between the two species leaves no doubt that they are conspecific. Therefore, P. anguliplanatus Kazantsev, 2021 , syn. nov. is recognised as a junior subjective synonym of P. gurkha Kazantsev, 2001 .

Plateros harmandi Bourgeois, 1902: 92 .

Plateros sikkimanus Kleine, 1928: 240 (synonymised by Kazantsev, 1991).

Material examined. Nepal, 1 male, “ Nepal, Mechi Prov., Ilam District., Rakse vill., 1700–2600 m, VII.1998, N.L. Orlov ”. Bhutan , 1 male, “ Bhutan, Thang , VII.1976, leg. Kunzang ” ( ICM) .

Distribution. Eastern Nepal (Ilam, Mechi), Bhutan, northeastern India (Darjeeling), China ( Yunnan).

Plateros karnaliensis Kazantsev, 2011: 166 .

Type material examined. Paratype of P. karnaliensis , Nepal, 1 male, “ Nepal: Karnali / Humla, 18 km WNW Simikot, Chumsa Khola ( Brücke ), 30°02′25″N 81°39′06″E, 2950 m, 20–22.VI.2001, A. Weigel leg.” ( ICM) GoogleMaps .

Distribution. Western Nepal ( Karnali, Humla).

Remark. The original description of the species contains a proofreading error that inadequately represents its coloration ( Kazantsev, 2011). A colour photograph of a paratype ( Fig. 12) is included here to complement the description. The aedeagus of P. karnaliensis closely resembles that of P. suturalis Pic, 1919 and P. macrosuturalis Kazantsev, 1991 , with its median piece appearing only slightly more robust (Fig. 27, cf. Figs 25, 26). In addition to the somewhat more robust aedeagus, P. karnaliensis is distinguished by the uniformly black pronotum and uniformly reddish elytra ( Fig. 12), whereas P. suturalis and P. macrosuturalis typically exhibit a black sutural stripe on the yellowish elytra and sometimes lighter lateral pronotal margins ( Figs 10, 11). However, the status of this taxon requires verification through the examination of additional material.

Plateros kumatai Nakane, 1983: 118 .

Material examined. Nepal, 1 male, “ Nepal, P. Mahakali, D. Mugu, Jumla , 35 km N, Dam, S, 29°35′24″N, 82°8′45″E, 2600 m, light trap, 26. VI GoogleMaps .2022, A. Weigel leg. #22–17” ( NME). Pakistan, 1 male, “ Pakistan, Jhika Gali , 2100 m, 21.VII.1979, W. Wittmer ” ( ICM) .

Distribution. Nepal ( Karnali, Mahakali, Phulchoki), northern Pakistan (Murree, Bava Gali, Jhika Gali).

Plateros laterculus Kazantsev, 1991: 174 .

Type material examined. Paratype of P. laterculus , Nepal, 1 male, “Nepal: Godawari, 10.VI.1976, W. Wittmer, C. Baroni U[rbani].” ( ICM) .

Distribution. Western Nepal (Godavari).

( Figs 11, 26)

Plateros macrosuturalis Kazantsev, 1991: 170 .

Type material examined. Paratype of P. macrosuturalis , Nepal, 1 male, “ Nepal : Phulchoki, 2600 m, 11– 14.VI.1976, W. Wittmer, C. Baroni U[rbani].” ( ICM) .

Distribution. Central Nepal (Phulchoki, Katmandu).

Remark. The aedeagus of P. macrosuturalis closely resembles that of P. suturalis ( Fig. 26, cf. Fig. 25). However, P. macrosuturalis can be distinguished from the latter by the smaller eyes, longer antennae, and broader black sutural elytral stripe ( Fig. 11, cf. Fig. 10). Nevertheless, the status of this species requires further verification through the examination of additional specimens.
