Omorgus (Omorgus) inclusus (Walker, 1858) (Figs. 24–27) Trox inclusus Walker, 1858: 208 (original description). Trox inclusus: Harold (1872): 105 (redescription); Arrow (1912): 57 (catalogue); Hoffmann (1931): 502 (checklist); Balthasar (1936): 438 (diagnosis); Haaf (1954a): 383 (description, diagnosis, illustration). Trox (Omorgus) inclusus: Scholtz (1982): 11 (catalogue). Omorgus (Afromorgus) inclusus: Zidek (2013): 11, 21 (checklist); Zidek (2017): 102, 113 (checklist); Kalawate & Patole (2018): 11990 (country records). Afromorgus inclusus: Pittino (2006): 79 (catalogue); Pittino & Bezdĕk (2016): 54 (catalogue). Type locality. “Ceylon [= Sri Lanka]”. Type depository. Syntype (male) at NHMUK. A second syntype located in RBINS. Distribution. China (Hainan), India, Sri Lanka, Vietnam (Scholtz 1982; Pittino & Bezdĕk 2016; Schoolmeesters 2022). Comments. While examining species belonging to the subgenus Afromorgus it became apparent that the inclusion of O. (A.) inclusus (Walker, 1858) in the subgenus Afromorgus should be reconsidered. The males of the species have the phallobasis clearly divided and membranous dorsally which correspond with the diagnostic features of subgenus Omorgus (sensu Scholtz 1986b). Therefore, we propose a new subgenus placement for O. (O.) inclusus (Walker, 1858), here by transferring it to the subgenus Omorgus.
