Etymology. – The species name “adsimulata ” (Latin for similar) refers to the similarity to Estola ruficeps .

Remarks. – Estola adsimulata sp. nov. is similar to E. ruficeps Breuning, 1943 ( Fig. 7-9 ; see also photographs on Bezark 2023a), but differs as follows: Body stouter; antennomere VIII light only basally; posterior third of elytra with brownish pubescent maculae interspersed; and abdomen not surpassing elytral apex in females. In E. ruficeps , the body is slender, antennomere VIII dark only apically, posterior third of elytra without brownish pubescent maculae interspersed, and abdomen surpassing elytral apex in females.
