Agathis Latreille, 1804

Type species: Agathis malvacearum Latreille, 1805.

Cenostomus Förster, 1862, first synonymized by Muesebeck and Walkley (1951) and confirmed by Baltazar (1966), De Santis (1967), Shenefelt (1970), Bhat and Gupta (1977) and Marsh (1979). Type species: Cenostomus lugubris Förster, 1862.

Aenigmostomus Ashmead, 1900, first synonymized by Sharkey and Mason (1986) and confirmed by Chou and Sharkey (1989) and Sharkey (1998). Type species: Microdus longipalpus Cresson, 1865.

Rhamphagathis Tobias, 1962, synonymized by Sharkey (1998). Type species: Agathis nasicornis Telenga, 1955.

Distribution: Holarctic, with more diversity in cool temperate regions. No species of Agathis has been collected in Th ailand or in the Oriental Region, but the occurrence of the genus in northern high-altitude areas is likely. Bhat and Gupta (1977) reported 45 species of Agathis for the Oriental region but they used a different generic concept that included Bassus s.s., Therophilus, and Lytopylus as they are defined in the present study. None of the species treated by Bhat and Gupta (1977) correspond to Agathis s.s., as it is interpreted here.

Diversity: Highly diverse in cool north-temperate climates.

Biology: Species generally attack lepidopterous larvae feeding in flower heads. There are numerous host records many of which are likely to be incorrect; host families that are reasonably certain include: Gelechiidae, Coleophoridae, Oecophoridae, Tortricidae, and Prodoxidae.

Phylogenetic Information. Sister to the clade composed of Lytopylus + Braunsia (Lytopylus corresponds to Bassus s.s. in Sharkey et al. 2006).

Diagnosis: Head rostriform or subrostriform (Fig. 17a); tarsal claws not bifid and with a basal lobe (as in Fig. 2b).
