  • Three halacarid species belonging to the genus Copidognathus are recorded from the shallow subtidal sands at Ko Taenae Islet (sand dune) off Ko Pha-Ngan Island, Thailand: Copidognathus thailandicus n. sp., C. euryalus Bartsch, 1997 and C. orarius Otto, 2001. Copidognathus thailandicus n. sp. comes close with C. cribrosoma (Police, 1909) and C. cribellus Bartsch, 1993 due to dorsal plates completely covered with rosette pores. Dissimilarities among them are discussed. Copidognathus euryalus and C. orarius are recorded hove for the first time from Thailand and away from its type locality. The present paper is also the first contribution on the taxonomy of Halacaridae (Acari) from Thailand.

  • A new species of marine Halacaridae, Copidognathus laevisetosus is recorded from Yeongdeok coast, Korea. In morphological aspects, the present new spe챠es is closely related to C. koreanus Chatterjee and Chang. Morphological similarities and dissimilarities between them are discussed. Copidognathus cerberoideus Bartsch is reported here for the first time from Korea and away from its type locality.

  • A new species of Halacaridae, Copidognathus koreanus is recorded from the Korean coast mostly among intertidal coralline algae. The present new species comes close with C.auroroe Newell, C.curtus (Hall), C.richardi (Trouessart) and C.unolaskensis Newell. Morphological similarities and dissimilarities among them are discussed. This is the first report on the marine halacarid mite from Korea.

  • Two species of halacarid mites belonging to genus Copidognathus viz C. jejuensis n. sp. and C. polyporus Bartsch, 1991 are described on the basis of the specimens collected from an algal bed in Jejudo Island, Korea. Copidognathus jejuensis n. sp. is closely related with C. dentatus Viets, C. dentipes Bartsch and C. eblingi Chatterjee. Morphological similarities and dissimilarities among them are discussed. Copidognathus polyporus Bartsch is reported for the first time from Korea and away from its type localitiy. A key to the species of genus Copidognathus from Korea is provided.

  • Copidognathus bengalensis n. sp. is described from Visakhapatnam coast, Bay of Bengal, India. The present species is characterized by posterodorsal plate (PD) with four costae made up of po rose panels, subdivided posterior cornea of ocular plate (OC), and two pairs of basirostral setae in female. This species is related to C. pulcher group, but the nature of po rose panels on anterior areolae of anterior dorsal plate (AD) and the setal ornamentation of legs were different between the members of C. pulcher group and the present new species.

  • A halacarid species of the genus Copidognathus is newly reported from Korea: C. daguilarensis Bartsch, 1997, which was described from Hong Kong. It is redescribed herein with detailed illustrations. Korean specimens coincide well with the original description, however, they showed two minor morphological discrepancies from it: quite shorter second palpal segment than the fourth and a modified dorsal seta on the second palpal segment. Korean specimens were rather smaller than the type specimens from Hong Kong, however, they did not show significant differences in the length to width ratios of important body parts. The number of perigenital setae was more variable in the Korean males, ranged 24-29 setae, versus 25-26 in Hong Kong's. Copidognathus daguilarensis is reported for the first time outside the type locality, and joins as the second member of the gibbus group in the northwest Pacific.
