4. Nomia apicalis Smith, 1857

Nomia apicalis Smith, 1857: 43, ♂.

Type material examined

None.

Type locality

Singapore.

Notes

Placing N. apicalis in combination with the genus Maculonomia Wu, 1982, Baker (1993: 192) wrote the following:

“A ♂ in the UMO type collection, labelled ‘SING.’ and ‘SING. 69’ [on either side of white disc (the ‘69’ does not indicate a date: a number of Wallace’s Malayan bees were similarly serially numbered) and ‘ Nomia apicalis Smith’ [blue paper] is the HOLOTYPE of this species. [ Melanomia Pauly, 1991, and Terminomia Baker MS, in Coll., are synonyms of Maculonomia Wu, 1982 .]”.

The holotype specimen is currently on loan (since 2016), so no photographs are provided.

Current status

Maculonomia apicalis (Smith, 1857) (Pauly 2009) .

Distribution

China to Indonesia (Kalimantan, Java), including Singapore (Pauly 2009; Ascher et al. 2022). A revision of this genus is required due to its taxonomic complexity, ongoing process of species description, and multiple species that are described from only one sex (e.g., Majumder et al. 2025; Tran et al. 2025).
