Stingless bees (Hymenoptera, Meliponini) are a large and diverse group including 59 extant groups, representing the main pollinators of Amazon forests. Among those, Trigona is one of the largest endemic genera of Neotropical Meliponini. In this work, we updated the molecular phylogeny of Trigona proposed by Rasmussen and Camargo (2008), including data from 59 new specimens collected in 2020 in the forests of northern Peru, through a multigene phylogenetic approach combining sequences from four gene fragments (16S, ArgK, EF-1a, opsin). Our results confirmed the monophyly of Trigona and of all proposed subgenera, except Aphaneura . In addition, most Trigona species-groups resulted monophyletic but the ‘ spinipes ’ and ‘ pallens ’ groups appeared paraphyletic and polyphyletic, respectively. Moreover, the cohesion of the “ fulviventris ” species group was hindered by the inclusion of T. williana (previously included in the “ pallens ” group) within this clade. Finally, we provided further evidence for a subdivision into two (geographically) distinct clades within T. guianae in northern Peruvian Amazon, which highlighted the importance of Neotropical biogeographical barriers in Meliponini divergence and evolution. Finally, to avoid misidentifications of Trigona specimens, the need for a robust taxonomic revision based on a cladistic approach of the whole genus is discussed.

Two nests of Hoplitis curvipes are described from Apulia (Italy) and Dagestan (Russia). Both nests consisted of two brood cells placed side by side under a stone. The cells were neither attached to each other nor to the substrate. They were constructed from leaf fragments, which were imbricately arranged, forming a cone-like structure; each leaf fragment consisted of a basal part that was masticated to leaf pulp and an apical part that protruded freely from the cell wall. The cell wall was formed by the fusion of the masticated basal parts of the leaf fragments and thus entirely consisted of leaf pulp. The cell was sealed with a closing plug made of pure leaf pulp; a few leaf fragments were glued to its outer surface. The cocoon consisted of two layers: the outer layer was restricted to the anterior portion of the cell and had several longitudinal air-exchange slits on its lateral surface, while the inner layer had an air-exchange orifice in its most anterior dome-shaped top. Results of measurements of brood cell dimensions and contents are provided. The nesting biology of species of the H. curvipes group is discussed.

In the course of evolution, animals and particularly insects, have developed efficient and complex mechanisms for survival. Biomimetics aims to find applications for these features of organisms (or organs) in industry, agriculture, and medicine. One of these features is the thin, flexible, and mobile insect ovipositor, which is also capable of carrying substances and drilling various substrates, usually of plant origin. Despite the well-studied structure of the ovipositor, the principles of its operation and real possibilities remain poorly understood. In our study, we first discovered an unusual behavioral pattern of oviposition of the female parasitoid Eupelmus messene Walker (Hymenoptera: Eupelmidae): she drilled with her ovipositor through the wall of a polystyrene Petri dish and laid her egg outside the dish. Due to the transparency of the plastic, we described the technique of ovipositor movement and studied its structure using scanning electron microscopy. Our research may contribute to developing minimally invasive guided probes and various other instruments.

The recovery of the first female specimens of Cryptopimpla goci Reynolds & van Noort in samples from Fernkloof and Grootbos nature reserves, and subsequent morphological reassessment of generic affinity based on female characters, no longer supports the placement of this species in Cryptopimpla. The transfer of C. goci to Lissonota Gravenhorst is proposed here: Lissonota goci (Reynolds & van Noort), comb. nov., and the female is described. New Afrotropical distributional records for the previously described Cryptopimpla species are presented and notes on the distribution and diversification of the species are also provided.

Hoplitis astragalisp. nov., a member of the H. monstrabilis species group, and H. dagestanicasp. nov., a member of the H. adunca species group, are described. The former species is known from Dagestan in Russia, Azerbaijan, and Turkmenistan, the latter only from Dagestan. Nests of H. astragali are described. Females of this species excavated burrows in a vertical clay cliff, but sometimes chose a horizontal surface for nest excavation, particularly at the entrance of old burrows of Xylocopa olivieri (Apidae). The nest burrows of H. astragali were either sub-vertical or sub-horizontal. The nests were composed of one to three brood cells, an empty vestibule in front of the outermost cell, and a closing plug at the nest entrance made of moistened mud. The inner surface of the cells was covered with a thin wall composed of compact soil, most probably built by the female bee after cell excavation. The pollen loaf was very liquid and had a spherical shape. The egg was deposited on its top. The cocoon consisted of a single thin layer, which uniformly covered the whole inner surface of the cell. There was one generation per year. The prepupae hibernated. Sapyga caucasica (Sapygidae) was recorded in the nests as a kleptoparasite. Both females and males of H. astragali exclusively visited flowers of two species of the genus Astragalus (Fabaceae).

A new fossil genus and species of fairyfly, Eotriadomeroides abjunctus Huber & Greenwalt, gen. and sp. nov. (Hymenoptera: Chalcidoidea: Mymaridae), is described and illustrated from a female preserved as a compression fossil in middle Eocene shale from the Kishenehn Formation, Montana, USA. It is compared to extant species of Neotriadomerus Huber, known only from Australia, and Triadomerus Yoshimoto, a Cretaceous amber fossil from Canada. It is suggested that these three genera, classified together in Triadomerini, likely the most ancestral lineage of Mymaridae, are evidence of the Middle or perhaps Late Jurassic origin of the family.

The present study reports the oviposition behavior of the ant parasitoid wasp, Ghilaromma orientalis, on an undescribed ant species from Lasius fuliginosus species group in Japan, illustrated by clear photographs. Previously, the oviposition behavior in the subfamily Hybrizontinae had been limited to species hovering on an ant trail and attacking larvae carried by worker ants. In contrast, in G. orientalis, whose oviposition behavior had not been reported to date, the wasp hung on the grass growing along the ants’ trail by its hind legs with its head down, and when workers with larvae pass by, directed its abdomen toward the larvae with its hind legs remaining on the grass. Our findings suggest that the subfamily Hybrizontinae employs two host-searching strategies—an active strategy previously known and the ambush-type host-searching strategy employed by G. orientalis. The ambush-type strategy affords G. orientalis the advantage of laying eggs in a narrow environment where wasps cannot fly without being noticed by ants. Moreover, by avoiding detection through ambush tactics, wasps are increasing their chance for attack, as ants continue to transport their larvae. However, the search range of wasps is reduced, which may limit the opportunities for parasitization. Additionally, while Lasius nipponensis has been observed as the sole known host of G. orientalis, the oviposition behavior has now been observed in an undescribed species of L. fuliginosus group, suggesting that G. orientalis may have a subgenus-specific host range.

Altogether, ten species of cuckoo bees of the tribe Dioxyini have been recorded from Europe, with two species distributed widely in the continent while others are restricted in distribution to only one or several countries in southern Europe. These ten representatives are classified into five genera: Aglaoapis, Dioxys, Ensliniana, Metadioxys and Paradioxys. Dioxys atlanticus is reclassified from a subspecies to a valid species, and new occurrence records of this species are reported. New synonymy is established for Dioxys cinctus = D. montanasyn. nov. The distribution, morphology, ecology and hosts of all species were reviewed from both published and unpublished sources. New red-list categories for each species were created according to the new records of occurrence. An identification key including all ten species and photographs of their whole bodies and main identification characteristics was prepared, and distribution maps for all species were created.
