<p class="Body"><strong>Morphological abnormalities in ticks (Acari: Ixodidae) from the Republic of Korea</strong></p>

Abstract

Tick-borne disease surveillance was conducted by tick drag among uncut grasses/herbaceous vegetation and mixed forest habitats from 2018–2020 at US Army Garrison Humphreys, Pyeongtaek, the Republic of Korea (ROK). While identifying ticks collected in the spring of 2020, teratological anomalies were observed in nymphs of Haemaphysalis longicornis (in one specimen, partial twinning of the posterior idiosoma, resulting in 2 anuses; in a second, asymmetry of the idiosoma) and Ixodes nipponensis (7 legs). These teratological observations in H. longicornis and I. nipponensis are reported for the first time in the ROK.
