We used whole-genome sequencing to assemble the first complete mitogenome from a
Mesentotoma Salmon, 1942 species.
Mesentotoma was included in phylogenetic analyses along with 21 mitogenomes of other Entomobryinae. Maximum likelihood and Bayesian inferences yielded similar results; both analyses indicated that
Mesentotoma is related to
Willowsia jacobsoni and
Entomobrya proxima. However, other genera of Entomobryinae, also lacking a mucronal spine (
Desertia Tshelnokov, 1979
Calx Christiansen, 1958 and
Isotobrya Womersley, 1934) need to be included in further analysis to verify their relationships, as well as other species of
Mesentotoma. Furthermore, five species previously assigned to
Entomobrya were transferred to
Mesentotoma due to the absence of a mucronal spine.
E. coeruleopicta Marlier, 1945 is a junior homonym of
E. coeruleopicta Schött, 1917 and a replacement name is proposed:
M. tranvercyana nom. nov., comb. nov. In addition, two new species of
Mesentotoma from a Brazilian island are described and characterized by reduced macrochaetotaxy. This represents the first record of
Mesentotoma in the Neotropical region, increasing its total number of valid species from eight to fifteen. We provided an identification key for the seven
Mesentotoma species recorded in the Tropical zone.
