View Image Gallery of Tribe Caberini

This tribe as treated by Forbes (1948) and by Hodges et al. (1983) includes the type genus Cabera Treitschke and a number of other genera including Erastria Hübner (= Syrrhodia Hübner) and allies (e.g. Rindge, 1950) where the larvae all feed on Ceanothus (Rhamnaceae), Records for Cabera, however, are from Betula (Betulaceae), Populus and Salix (Salicaceae).

The inclusion of Erastria brings the family-group name Erastriinae, originally applied (Herrich-Schäffer, 1845) as Erastridae to taxa that are now referred to the Acontiinae in the Noctuidae (Nye, 1975; Kitching, 1984), into synonymy with Caberini. Hemming (see Fletcher, 1979) dated the relevant part of Herrich-Schäffer at 1851, whereas Caberini derives from Caberites of Duponchel (1844[-1846]), appearing in a part that was published in 1845. Therefore Caberini has priority. Deiliniinae of Warren (1893) must also be subordinated, as Deilinia Hübner is a synonym of Cabera, as must Catopyrrhinae (Warren, 1894), based on Catopyrrha Hübner, a subjective synonym of Erastria.

Forbes (1948) referred to a feature of the adult that may serve to define the tribe: a swollen base to the hindwing subcostal vein. However, this is not apparent in all the Rhamnaceae feeding taxa referred to here.

Larval characters also serve to unite members of the tribe, as revealed by Singh (1953), McGuffin (1972-1987) and Sato (1976), bringing in the Petelia Herrich-Schäffer group of genera to the Caberini (Sato) as well as the Oriental member of the Erastria group, Hyperythra Guenée (as Syrrhodia in Singh). The Petelia-like Australasian genus Casbia Walker has larvae resembling those of other members of the group (the type species rectaria Walker, was reared in New Caledonia by Holloway (1979)). It is diverse in Australia and extends to the S. Moluccas, New Caledonia, Fiji and Tonga. The particular features are given by Singh as: 4 setae (cf. 5) on each side of the meson of the anal shield; seta SD1 on A8 distinctly anterior to the spiracle rather than above it; ocellus 4 separated from the antennae by less than (cf. twice the distance) its diameter. More general features are a central interruption in the mesoseries of crochets on the prolegs, shared with the Hypochrosini, Scardamiini and the Cassymini and, shared with the last, the plesiomorphic feature of four (cf. five) external setae on the ventral proleg.

The genus Petrodava Walker is an African member of the Erastria group, and there are a number of Petelia-like genera in the Neotropics as well as taxa misplaced in Petelia: Thysanopyga Herrich-Schäffer, Oenothalia Warren, Perissopteryx Warren, Lobopila Warren and Oenoptila Warren. Some of these Neotropical taxa are reviewed by Krüger & Scoble (1992).

There are no obviously definitive genitalic features. In the male there are weak setose socii, and the gnathus is vestigial. Several genera have coremata at the base of the sacculus. Females show a variety of signum form, from a typically ennomine, spined, stalked disc to single or multiple sclerotised ridges or flanges (Casbia) or absence (many of the Petelia complex).

In most genera the male antennae are bipectinate over the basal two-thirds to three-quarters. Apart from Cabera, there is a very strong association with the plant family Rhamnaceae. It has already been mentioned that many N. American taxa have larvae that feed on Ceanothus. Japanese taxa of the Petelia complex are recorded from Hovenia (Sato, 1970). Singh (1953) notes Petelia and Hyperythra (as Syrrhodia) taxa on Hovenia, Gouania and Ziziphus. There is a record of Petrodava madecassaria Boisduval from Ziziphus in Africa (Pinhey, 1975). Casbia species have been reared from Alphitonia, Cryptandria and Pomaderris (Holloway, 1979; McFarland, 1979; Common, 1990). Two Thysanopyga species have been reared from Gouania (J. Rawlins in Krüger & Scoble, 1992; M.J. Scoble pers. comm. ex litt. J. Rawlins).
