( 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 .
