FIGURE 4 in Integrative taxonomy identifies Macrobiotus papei, a new tardigrade species of the Macrobiotus hufelandi complex (Eutardigrada: Macrobiotidae) from the Udzungwa Mountains National Park (Tanzania)

FIGURE 4. Macrobiotus papei sp. nov.—mouth opening and the oral cavity armature seen in SEM (paratype): A– mouth opening with six peribuccal sensory lobes and ten lamellae surrounded by large pores; B–C—the oral cavity armature of a single paratype seen in SEM from different angles. Arrows indicate pores in the irregular ring of pores surrounding the peribuccal lobes, filled arrowheads indicate teeth of the first band, empty arrowheads indicate teeth of the second band, the peaks in the dorsal ridge of the third band that correspond with teeth of the third band, in species with better developed oral cavity armatures are marked with "Ld" and "Md" (the dorso-median tooth comprises several small peaks visible as thickenings in PCM), whereas the teeth of the ventral portion are marked with "Mv" (medio-ventral tooth) and "Lv" (lateral teeth).
