The term allomorph is just linguistobabble for a piece of language, such as a suffix, that shows predictable variation in its form in different positions or circumstances.
Since -cve is locative of -cva, listing it as another allomorph is another mistake.
Ta-Den wants to get his hands on the allomorph, sure as can be.
Since it isn't adequately explained under what conditions -ia is yet a fourth allomorph of the same suffix, I consider it a distinct plural marker on its own.
The terminating sequence -cv could only be the abbreviation of plural suffix -cva which is a regular allomorph of -xva when following a sibilant.
Next, luθcva is transparently a nomino-accusative plural because -cva pl. is an allomorph of the more typical form -χva following aspirate θ.
My attentive readers may have noticed that I've already asserted several times on this blog that -va a plural inanimate ending is an allomorph of -χva.
It turns out that there may be a case for -cva being the proper allomorph of the inanimate plural after sibilants instead of -va.
The suffix -va is a known allomorph of -χva that is used after stems ending in certain consonants eg: PyrT 1.i-ii heramaśva 'idols'; see Etruscan grammar pdf by Micheal Weiss of Cornell University.
Now that allomorphy can be eradicated in the germ line, parents no longer pass on the allomorph trait to their offspring.
