... Understanding of evolutionary history and speciation events to inform phylogeography of extant species can be gleaned from the fossil record. However, the fossil record for Australian freshwater turtles contains many gaps and interpretation of the fossils that are known is difficult because of poor knowledge of the morphology of extant forms. There are no fossils currently assigned to short-necked ...

Abstract:
... Microgastrine wasps are among the most species‐rich and numerous parasitoids of caterpillars (Lepidoptera). They are often host‐specific and thus are extensively used in biological control efforts and figure prominently in trophic webs. However, their extraordinary diversity coupled with the occurrence of many cryptic species produces a significant taxonomic impediment. We present and release the ...
... Phaneta comprises a large genus of Nearctic tortricids with several species that are difficult to delimit using morphological characters. We examined Phaneta tarandana (Möschler 1874) and P. montanana (Walsingham 1884), using morphology and DNA. Our results upheld the distinction between these two species, even though the wing coloration and male genital characters traditionally used to diagnose t ...
... Temperate reefs, built by multilayers of encrusting algae accumulated during hundreds to thousands of years, represent one of the most important habitats of the Mediterranean Sea. These bioconstructions are known as “coralligenous” and their spatial complexity allows the formation of heterogeneous microhabitats offering opportunities for a large number of small cryptic species hardly ever consider ...

Abstract:
... The structure of the male gonopods of millipedes has been considered to be species-specific. As such, gonopods—which aid in copulation and sperm transfer—are used in the taxonomic diagnosis and description of species. However, it was recently demonstrated that gonopod morphology is not always characteristic of species. Diagnoses based on gonopod morphology can therefore result in underestimation o ...
