Description of a New Dermacentor (Acari: Ixodidae) Species from Thailand and Vietnam.
A new tick species belonging to the genus Dermacentor Koch, 1844, namely, Dermacentor filippovae n. sp., is described. All stages of this species are similar to those of D. auratus Supino, 1897, D. compactus Neumann, 1901, and D. limbooliati Apanaskevich and Apanaskevich, 2015 with which it was previously confused. Males of D. filippovae may be distinguished from those of D. auratus, D. compactus, and D. limbooliati by the following suite of characters: conscutum broadly oval with convex lateral sides, widest posteriorly; trapezium-like shape of pseudoscutum; central brown patch on conscutum indistinct; coxa I with internal spur narrowly triangular with tapering apex and external spur fairly long, narrowly triangular with tapering apex; numerous internal spurs on coxa IV; and trochanter I with moderate, broadly triangular spur with tapering apex. Females of D. filippovae may be distinguished from those of D. auratus, D. compactus, and D. limbooliati by the following suite of characters: central patch of scutum narrow, distinct line interrupted around midlength; more rounded shape of scutum; long and distinct alloscutal setae; moderately broad U-shaped genital aperture with preatrial fold bulging anteriorly and thereafter sharply sloping to flat surface posteriorly; coxa I with internal spur narrowly triangular with tapering apex and external spur fairly long, narrowly triangular with tapering apex; and trochanter I with moderate, broadly triangular spur with tapering apex. Dermacentor filippovae is known from Thailand and Vietnam where the adults were collected from wild boar, Sus scrofa L., and vegetation.
