Figure 33. Caudal skeleton of Ariomma cf. n/griorgenfeo, drawing of a cleared-and-stained preparation from a 28-mm specimen. All elements identified in Figure 1. characters of the family, far from the con- dition of others in the suborder, are prob- ably due to the shift the ariommids have made to an adaptive zone atypical for stro- mateoids (see below: Natural history, p. 93). Ariomma presents a confusing array of characters which could suggest affinities with the centrolophids, the nomeids, or the stromateids. The well ossified sclerotic bones, minute body pores, and extremely deciduous scales are characters held in common with the advanced Seriolella group of the centrolophids and the diminutive Cuhiccps pauciradiatus group of the no- meids and the stromateids. The teeth on the papillae occur all along the bony stalk, and the jaw teeth of Ariomma indica are cusped. Both characters are typical of stro- mateids. The general body shape is like Seriolella. The complete absence of palatal dentition suggests an affiliation with the line connecting the advanced centrolophids with the stromateids. However, Ariomma has two distinct dor- sal fins and very large scales, and the bony bridge over the anterior vertical canal of the ear is either very reduced or absent, all in marked contrast to the situation in centrolophids and stromateids. These con- ditions are found in the Cuhiceps pauci- radiatus group, nomeids which in addition have reduced palatal dentition. The Ariom- midae are probably derived from some- where in this line, and have lost the teeth on the palate and basibranchials.
