Image de Dermacentor Koch 1844

Description :

Under a magnification of 3043X, approximately 8 times greater than PHIL 9963, this scanning electron micrograph (SEM) depicted a dorsal view of an unidentified male Dermacentor sp. tick found upon a cat in the suburbs of Decatur, Georgia, which measured approximately 3.5mm from its gnathosoma (i.e., capitulum), which is where its mouthparts are located, to the distal abdominal margin (PHIL 9961). Note in PHIL 9959 and 9960, that the entire dorsum of this tick’s abdomen is covered by its tough scutum, or shield, categorizing it as a male. In female Ixodid-species ticks, the scutum only partially covers the dorsal abdomen. Seen clearly in this image is the foliate covering of the tick’s skin-piercing hypostome, which is located in what appears to be a trough between its pedipalps.
