Treatment

Genus Arearia Seyrig, 1952 View in CoL

Arearia Seyrig, 1952: 17 View in CoL . Type species: Arearia paradoxa Seyrig, 1952 View in CoL , by original designation.

Diagnosis

One of the key features that separates Arearia from all the other Afrotropical Phaeogenini is the presence of a deeply impressed sternaulus, extending beyond the mid-length of the mesopleuron. Moreover, the genus can be further distinguished by the combination of the following characters: (1) gastrocoeli and thyridia absent; (2) mandible bidentate; (3) malar space with subocular sulcus present and distinct; (4) areolet open (3 rs-m absent).

Remarks

Seyrig (1952: 17) placed Arearia within the subfamily Cryptinae (tribe Stilpnini ) due to the very long, deeply impressed sternaulus. Later on, it was transferred to Ichneumoninae by Townes (1971: 233), after examination of the type. So far, the genus occurs only in the Afrotropical region with two species already described: Arearia oxymoron Rousse & van Noort, 2013 , in South Africa, and Arearia paradoxa Seyrig, 1952 , in Madagascar ( Rousse et al. 2013; Yu et al. 2016).
