Arthropod Parasitiformes amber inclusions. (A) Holothyrida, Neothyridae. A scavenger mite found together with insect inclusions in the amber from which it was separated for analysis. The figures provide details of the general look of the piece, measurements, and critical details for identification. Insect inclusions and amber without inclusions derived from this amber piece were processed as controls. (B) Cornupalpatum tick species for which stereomicroscope and Scan Ct images show the damage of the body preventing an accurate determination to the species level.

Neothyridae gen. sp. Elongation factor 1-alpha (A0A2H4RIF7). Sequence and phylogenetic analysis of the protein identified with highest coverage (244/342 amino acids, 71.3%). Neothyridae form a separate clade within Holothyrida mites.
