Godfray, Charles J. & Achterberg, Cornelis Van, 2024, Annotated Checklist of the European Dacnusini and the Dapsilarthra genus group of the Alysiini (Hymenoptera: Braconidae, Alysiinae), Zootaxa 5513 (1), pp. 1-73 : 42

Coelinius Nees, 1818

Type species: parvulus Nees

CHAENON Curtis, 1829 (type species: anceps Curtis ( =parvulus Nees ))

COPISURA Schiødte, 1837 (type species: rimatur Schiødte ( =parvulus Nees ))

COPIDURA Förster,1862 (type species not designated)

Literature: Griffiths I-856.

Notes: Griffiths (1964) proposed that Polemochartus and Coelinidea should be included as subgenera of Coelinius . Wharton and Austin (1991), Wharton (1994), Kula (2008) and Kula and Zolnerowich (2008) supported the concept of an enlarged Coelinius , including Sarops , but, pointing to intermediate taxa in the Oriental Region, argued against the retention of subgenera. van Achterberg (2014) (and in Fauna Europaea 2023) treats this group as five genera (including the more recently described Eucoelinidea Tobias ) and provides a generic key using new characters. Astrafurova in Tobias (1998) uses a broad concept of Coelinius with subgenera though their conceptions of Coelinidea (which she calls Lepton ) and Coelinius are not identical to those of van Achterberg (2014). Taxapad lists ~70 species of Coelinidea and Coelinius from Europe, Asia, Africa, Australasia & North America though this includes several nomina dubia and duplicate entries. There is one widespread Palaearctic species of Coelinius as interpreted here and at least one further poorly known species.

Coelinius parvulus (Nees, 1811; Chaenon )

Synonymy: ? cultriformis (Latreille, 1802, Ichneumon ); circulator (Gravenhorst, 1807, Ichneumon ) preocc.; anceps ( Curtis, 1829, Chaenon ); rimator (Schiødte, 1837, Copisura ); bicarinatus Herrich-Schäffer, 1838 ; flexuosus Herrich-Schäffer, 1838 .

Literature: Marshall (1897-1900, p. 332); Marshall (1899, p.7); Maréchal (1938) (detailed and illustrated redescription); Tobias (1986).

Hosts: No information but considering related genera probably Chloropidae .

DNA Barcode: Yes. Several Coelinidea spp. in the BOLD database were erroneously labelled C. parvulus .

Notes: The taxon Thompson called circulator Gravenhorst is not parvulus but a species of Coelinidea ( Maréchal 1938) . Thomson (1895) discussed a variety with a red prothorax that Marshall (1891 -1896) thought might be ruficollis ( = procerus ) but Maréchal (1938) considered distinct and labelled var. bicolor commenting it might deserve species status.

venustus (Marshall, 1898)

Literature: Marshall (1897-1900, pp. 247, 333)

Notes: Marshall states that the only male specimen is very similar to C. parvulus ( = anceps ) but larger with a yellow prothorax. Not recognised since original description and provisionally placed in Coelinius .
