We present Biomedisa, a free and easy-to-use open-source online platform developed for semi-automatic segmentation of large volumetric images. The segmentation is based on a smart interpolation of sparsely pre-segmented slices taking into account the complete underlying image data. Biomedisa is particularly valuable when little a priori knowledge is available, e.g. for the dense annotation of the training data for a deep neural network. The platform is accessible through a web browser and requires no complex and tedious configuration of software and model parameters, thus addressing the needs of scientists without substantial computational expertise. We demonstrate that Biomedisa can drastically reduce both the time and human effort required to segment large images. It achieves a significant improvement over the conventional approach of densely pre-segmented slices with subsequent morphological interpolation as well as compared to segmentation tools that also consider the underlying image data. Biomedisa can be used for different 3D imaging modalities and various biomedical applications.

“…The adaptations in the metatarsus might help anchor the wasp to the substrate. A more extreme form of enlarged tarsal structures of the hind legs has been observed in Trassedia Cancemi, 1996 (Ceraphronoidea), where the hind tarsomeres and hind tarsal claws are almost twice as long and wide as these structures in the preceding legs (Mikó et al 2018). It is hypothesised that the enlarged hind tarsomeres and tarsal claws in Trassedia are adaptations to anchoring the body while the wasp uses its chisel-shaped tip of the 7 th metasomal sternite to cut into hard substrates (Mikó et al 2018).…”

Within the well-studied Palearctic entomofauna, it is often assumed that the discovery of new species is limited to resolving cryptic species complexes within dark taxa. Herein, we describe a highly distinctive species of Aphanogmus Thomson, 1858 (Hymenoptera: Ceraphronidae) from Germany and provide a COI barcoding sequence for the new species. We present a 3D reconstruction of the holotype based on micro-CT to serve as a cybertype. The females of Aphanogmus kretschmanni Moser sp. nov. are diagnosed by two rows of prominent spines on the ventral edge of the 7th metasomal sternite, a character set that has not previously been found in Hymenoptera. We analyse the functional morphology of the ovipositor mechanism and discuss hypotheses regarding the functional implications of the unique modification of the 7th metasomal sternite. Possible host associations are reviewed and the taxonomic placement of the new species is discussed.

“…Nine of the sixteen known genera of Ceraphronidae, for example, are rare, monotypic taxa, defined primarily by autapomorphies (Masner and Dessart 1967;Dessart and Cancemi 1987). Species-level characterization and delimitation is relatively robust, compared to other Hymenoptera, due to the informative nature of the male genitalia (Dessart 1963a;Mikó et al 2018;Ulmer et al 2018). To study the male genitalia of minute specimens, often less than a millimeter in length, is challenging.…”

The Waterston’s evaporatorium (=Waterston’s organ), a cuticular modification surrounding the opening of an exocrine gland located on metasomal tergite 6, is characterized and examined for taxonomic significance within the parasitoid wasp family Ceraphronidae. Modification of the abdominal musculature and the dorsal vessel are also broadly discussed for the superfamily Ceraphronoidea, with a novel abdominal pulsatory organ for Apocrita being discovered and described for the first time. Cuticular modification of T6, due to the presence of the Waterston’s evaporatorium, provides a character complex that allows for genus- and species-level delimitation in Ceraphronidae. The matching of males and females of a species using morphology, a long standing challenge for the group, is also resolved with this new character set. Phylogenetic analysis including 19 Waterston’s evaporatorium related characters provides support for current generic groupings within the Ceraphronidae and elaborates on previously suggested synapomorphies. Potential function of the Waterston’s organ and its effects on the dorsal vessel are discussed.
