In the present paper, we describe a second species of Acerentuloides, provide a generic diagnosis, and discuss the phylogenetic position of the genus Acerentuloides, subfamily Berberentulinae and family Acerentomidae within Acerentomata.
Phylogenetic affinities were analyzed by comparing the obtained COI, 18S rRNA, 28S rDNA D1--D2, and 28S rDNA D3--D6 sequences with sequences of other members of Acerentomidae published in previous works (Shrubovych et al.
The presence of a vesicle on the maxillary gland is found in only a few genera (Vesiculentomon Rusek, 1974, Nosekientomon (Nosek, 1977), Callientomon Yin, 1980, and Acerella Berlese, 1909), but they belong to other subfamilies of Acerentomidae (Tuxen 1964; Shrubovych et al.
Phylogenetic analyses, using both parsimony and ML, strongly support Acerentomidae as monophyletic (Fig.
