Description
Associated with beetles , including bark beetles ( Scolytinae ) [3] . Among the hosts are several economically important species of bark beetles, for example, Dendroctonus ponderosae and bark beetle typograph ( Ips typographus ) [3] [4] [5] . Like other members of the diplogastrid family, representatives of the genus Micoletzkya have mobile opposing teeth and exhibit oral dimorphism in the form of two phenotypes : stenostatic (narrow mouth and small teeth) and heuromatous (wide mouth and large teeth) [6] . These two alternative phenotypes represent resource polyphenism and specialization in nutrition by various food sources, such as microorganisms and other nematodes, respectively [7] . Nematodes of the genus Micoletzkya have strictly defined hosts and most of their species are associated with only one single species of host beetles. Phylogenetic data indicate that genus diversification was significantly affected by the evolutionary radiation of bark beetles [5] .
Systematics
Over 25 species. The generic name is given in honor of the Austrian nematologist Henrich Micoletzky [3] [8] .
