This study presents a comprehensive revision of the genus Heinrich, 1967. We describe a new species, Dal Pos & Di Giovanni, , from Burundi, marking the first documented occurrence of an Ichneumoninae species in the country. Additionally, we provide the first diagnostic description of the female Heinrich, 1967 and report a new occurrence of this species in KwaZulu-Natal.

Background: Myrmeleontidae are conspicuous insects with moderate species diversity, which are reasonably well studied in Europe. However, dedicated samplings in the Mediterranean region carried out in the last years suggest that the state of knowledge of the representatives of this family occurring in outhern Europe is far from ideal. Over 40 species of antlions and owlflies are reported from Italy, of which a few are only known from the islands of the Sicilian Channel.

- Species richness is crucial for understanding biodiversity, highlighting under-studied groups like Darwin wasps, where previous estimates suggested nearly 11,000 species compared to only 2,322 recorded.
- New estimates based on various data sources indicate that only 13-22% of Darwin wasp species are known in five heavily studied Afrotropical countries, with estimates of total species ranging from 9,206 to 15,577.
- Factors contributing to the gap between recorded and estimated species richness include logistical and financial challenges, alongside post-colonial influences affecting research efforts.
(1) Background: when the pathologist faces histologic slides from colonoscopies in daily practice, given the large number of entities and etiologies under inflammatory bowel conditions, in-depth definition of the histological spectrum and the recommendations of current guidelines are often not enough to conclusively define a diagnostic framework. Histological patterns should be organized hierarchically in flowcharts that consider the correlation with clinical data. We conducted an online survey asking a group of gastroenteropathologists to apply a pattern classification based on the most significant lesions in colitis differential diagnosis: crypt distortion and activity.
