The complete mitogenome of a South African cryptic species of tadpole shrimp within the Triops granarius (Lucas, 1864) species group

Trechodes intermedia sp. nov. and T. kogelbergensis sp. nov. are described from South Africa. A third species, T. humeralis (Jeannel, 1930) comb.nov. is transferred to Trechosia Jeannel from the genus Cothresia Jeannel. All three species are macropterous, endemic to the South African Cape region, and together represent a new species group of the genus Trechosia. Keys to the species groups of the genus Trechosia and to the species of the new T. intermedia group are provided.

Metabolomic Approach

Molecular genetic methods can distinguish divergent evolutionary lineages in what previously appeared to be single species, but it is not always clear what functional differences exist between such cryptic species. We used a metabolomic approach to profile biochemical phenotype (metabotype) differences between two putative cryptic species of the earthworm Lumbricus rubellus . There were no straightforward metabolite biomarkers of lineage, i.e. no metabolites that were always at higher concentration in one lineage. Multivariate methods, however, identified a small number of metabolites that together helped distinguish the lineages, including uncommon metabolites such as N ε-trimethyllysine, which is not usually found at high concentrations. This approach could be useful for characterizing functional trait differences, especially as it is applicable to essentially any species group, irrespective of its genome sequencing status.

Species Complexes

The Triatoma phyllosoma species group includes 17 species of kissing bugs, most of them implicated in the transmission of Chagas disease in the Americas. The species of this group are T. bassolsae Alejandre-Aguilar, Nogueda-Torres, Cortéz-Jímenez, Jurberg, Galvão & Carcavallo, 1999, T. brailovskyi Martínez, Carcavallo & Pelaez, 1984, T. dimidiata (Latreille, 1811), T. gerstaeckeri (Stål, 1859), T. gomeznunezi Martínez, Carcavallo & Juberg, 1994, T. hegneri Mazzotti, 1940, T. huehuetenanguensis Lima-Cordón, Monroy, Stevens, Rodas, Rodas, Dorn & Justi, 2019, T. indictiva Neiva, 1912, T. longipennis Usinger, 1939, T. mazzottii Usinger, 1941, T. mexicana (Herrich-Schaeffer, 1848), T. mopan Dorn, Justi, Dale, Stevens, Galvão, Lima-Cordón & Monroy, 2018, T. pallidipennis (Stål, 1872), T. phyllosoma (Burmeister, 1835), T. picturata Usinger, 1939, T. recurva (Stål, 1868), and T. sanguisuga (LeConte, 1855). The validity of some species of the group was uncertain, because of both cryptic species and hybrid occurrence. Species exhibiting these particularities were formerly classified in the T. dimidiata and T. phyllosoma complexes. Although we recognize the historical value of these species complexes, we do not recommend their further use. Instead, we recognize the T. phyllosoma species group here reviewed, considering the current knowledge of the systematics and reproductive behavior of the group. We implement the cohesion species concept, validating the species status of T. bassolsae, T. longipennis, T. mazzottii, T. pallidipennis, T. phyllosoma, and T. picturata. We also provide diagnoses, photographs and a taxonomic key including the recently described species.

Group Family

Electromorphic variation at 33 presumptive genetic loci within and among samples of the Liomys pictus species-group from western, southern, and eastern Mexico was examined. Levels of heterozygosity and polymorphism within samples were low when compared with those of rodents in general, and genie divergence among samples was very high, resulting in a discontinuous distribution of alleles among localities. We hypothesize that some of these geographic discontinuities result from intrinsic barriers to gene flow within L. pictus. Genie variation in or near zones of overlap suggest that the following pairs of taxa segregate as distinct biological species: L. p. plantinarensis and L. spectabilis; L. p. plantinarensis and L. p. pictus; L. p. hispidus and L. p. pictus. Liomys spectabilis is more similar genically to adjacent populations of L. p. pictus in northwestern México than samples of L. pictus are to each other. As presently defined, L. pictus appears to be paraphyletic and probably is a composite of several morphologically cryptic species.
