Agrilus dianthus Kerremans , lectotype Ψ, MCSN, designated by Descarpentries & Villiers (1963): “Bhamò Birmania Fea [leg.] [p] X [h] 188 [p] 6 [h] \ Typus [p] [red ink, red bor­ der] \ dianthus Kerr. [h] [black border] \ A. dianthus Kerr. typus! [h] [yellow label] \ dianthus Kerr. Type [Kerremans' manuscript] \ Museo Civico di Genova [p]”. Number of syntypes is unknown. Descarpentries & Villiers (1963: 52, 53–54) by the mention about type: “ Birmanie (type de dianthus au Musée de Gênes)” validly fixed the lectotype (ICZN, Article 74.6) and they proposed it as a subspecies of A. acutus .

Type locality. [ Myanmar] Bhamò [24°16'N, 97°14'E].

Agrilus nodosus Kerremans , lectotype ɗ, BMNH, by present designation: “SYN­ TYPE [p] [round label with blue border] \ Bima Boucard [leg.] [Kerremans' manuscript] \ nodosus Kerr. Type [Kerremans' manuscript] \ Kerremans 1903 –59. [p]” and one paralectotype from the same locality as lectotype. Described from two specimens. Descarpentries & Villiers (1963: 53, 54) proposed it as a synonym of A. acutus dianthus .

Type locality. Bima [site unlocated]. Descarpentries & Villiers (1963) assumed Bima to be Birmanie [ Myanmar]: “ Birmanie (type de dianthus au Musée de Gênes)”.

Agrilus coelicus Bourgoin , lectotype Ψ, designated by Descarpentries & Villiers (1963), MNHN: “Vieng Vai 12­VI­1918 Luang Prab. [h] \ Agrilus coelicus Type Bourg. [h] \ TYPE [p] [red ink] \ MUSÉUM PARIS 1935 coll. A. THÉRY [p]”. Single paralectotypes are preserved in BMNH and ISNB. Number of syntypes is unknown. Descarpentries & Villiers (1963: 54) by the mention about type: “Louang­Prabang (type de coelicus , Muséum de Paris)” validly fixed the lectotype (ICZN, Article 74.6). Descarpentries & Villiers (1963: 54) proposed it as a synonym of A. acutus dianthus .

Type locality. [ Laos] Luang Prab. [= Louangphrabang province], Vieng Vai [site unlocated]. No type locality was cited by Bourgoin, but presumably “Indo­Chine française” as indicated in the title. The type locality is stipulated from the place of origin of the lectotype ( ICZN, Article 76.2.).

Agrilus dorri Bourgoin , lectotype Ψ, designated by Descarpentries & Villiers (1963), MNHN: “Long Xuyen Cochinchine Dorr [p] \ Agrilus Dorri A. Bourgouin [black ink] Type [red ink] [h]”. Number of syntypes is unknown. Descarpentries & Villiers (1963: 54) by the mention about type: “ Type de dorri au Muséum de Paris” validly fixed the lectotype (ICZN, Article 74.6). As a synonym of A. acutus dianthus proposed by Descarpentries & Villiers (1963: 54).

Type locality. [ Vietnam] Cochinchine: Long Xuyen [10°23'N, 105°25'E].

Remarks. Agrilus dianthus has an allopatric distribution with A. acutus and has been considered as a subspecies of A. acutus . The examination of numerous specimens has revealed that A. dianthus is a generally larger (6.6–10.2 mm) and well distinguished species (see remarks at A. acutus and key to species).

All records from peninsular SE Asia cited under the name A. acutus or its synonyms pertains to A. dianthus , for example Baudon 1961: 75 (as A. acutus ). Very interesting is a single record of A. dianthus from the Indonesian part of Borneo.
