The species idea is quite good, but can have a better development than a leader that jumpstart them.

Instead you can go with:
>Goblinoids can be divided by different castes by female mother as each goblin can absorb the traits of the female
>Artisans, birthed from dwarven wombs, these goblinoids can manufacture and produce regular to high quality goods for their brethren, slightly smaller but far more stockier than the standard goblinoid, have a slightly longer lifespan of a goblinoid. (you can add a lifespan of the common goblin and add a better number)
>Merchants, This kind of goblinoid are far more intelligent, but are shrewd and greedier than their common counterpart. This caste are natural strategist and can organize raid bands to capture females to sell with the distinct goblinoid tribes (then kingdoms), Later when their first kingdom was founded, this caste became the most important for them due they could find a good female to sell or opened breeding stalls for entertainment.
