Synonyms and other taxonomic changes

Higher taxonomy revised by Sharkey et al. (2006) to include 4 tribes.(1)

Higher taxonomy further revised by Sharkey & Chapman (2017) to include 7 tribes.(2)

Explanation of Names

Agathidinae Haliday, 1833

Numbers

~100 species(3), 15 genera (+1 undescribed) in our area(4); ~2,000 spp. in ~40 genera worldwide.

1. Tribe Agathidini: Aerophilus (35 spp.), Agathis, Alabagrus (6 spp.), Neothlipsis, Plesiocoelus, Pneumagathis

2. Tribe Agathirsini: Agathirsia, Crassomicrodus, Gelastagathis

3. Tribe Cremnoptini: Cremnops, Zacremnops

4. Tribe Disophrini: Zelomorpha (3 spp.)

5. Tribe Earinini: Earinus (5 spp.)

6. Tribe Lytopylini: Lytopylus (2 spp.)

7. Tribe Mesocoelini: Therophilus, undescribed gen. nov. (annulipes-group)

Identification

Keys to genera in Sharkey (2004),(3) Sharkey (2006),(5) and Sharkey et al. (2022).(4)

Fore wing M+CU not tubular in basal 1/3 or more

Fore wing 3RSb terminating at wing margin near stigma and distant from wing apex

Occipital carina absent

Wing venation

Range

Worldwide

Habitat

Most terrestrial habitats. Genera Agathis and Earinus are more species-rich in temperate regions. In Agathis and Crassomicrodus, some species tend toward desert habitat. Other genera most diverse in humid tropics.(6)

Food

hosts: Lepidoptera larvae

Life Cycle

Solitary koinobiont endoparasitoids (a few are gregarious)

Remarks

Among the many species useful for insect pest control in the Nearctic are: Agathis pumila against larch casebearer; A. stigma and Cremnops laricella against sugarcane borer; & Bassus unicoloratus against potato tuberworm.

"There are three main Agathidine genera with the 'long face' (Agathus, Bassus, and Cremnops). Agathus is almost always entirely black, whereas Bassus and Cremnops are red & black. Cremnops has a carina extending from the lateral margin of the antenna to the lateral ocelli. The carina is absent in Bassus." (Comment by Dr. Michael J. Sharkey, 2007).(7)

Editor's note: further revision has split the former understanding of Bassus into additional genera such that no Bassus occur in our area.
