 DOI: doi.org/10.1080/00222933.2026.2663058 

ABSTRACT

A new genus of Pedunculinae (Hymenoptera: Ichneumonidae) is described: Attenboroughnculus De Ketelaere and Broad, gen. n. a monotypic genus for Attenboroughnculus tau De Ketelaere and Broad, sp. n. collected in central Chile. This is the fourth genus and fourth described species of Pedunculinae and the second from the Neotropics. Each of the four known genera is defined by putative apomorphies, included in an identification key, and photos of each are provided.

KEYWORDS: Austral, Darwin wasps, Gondwanan, new species, South America, taxonomy, Sir David Attenborough

Attenboroughnculus De Ketelaere and Broad, gen. n.

  

Etymology: 

This unique genus from Chile has been named after Sir David Attenborough ahead of his 100th birthday, celebrating the broadcaster and biologist’s highly distinctive contribution to our understanding of the natural world. David Attenborough has featured Chile’s diverse, extreme landscapes in several documentaries, emphasising the unique environmental challenges and ecological resilience of species within the country.

Sir David has also filmed several scenes with parasitoid wasps, famously termed the ‘bodysnatcher wasp’ by the broadcaster in the Trials of Life, first broadcast in 1990. He has used his work to reveal the intimate, unseen or overlooked within nature. This resonates in the discovery of this species in an unsorted drawer within the collections of the Natural History Museum, London.

In 2023 Sir David revealed a new bronze quote outside the Natural History Museum, London, reading: The future of the natural world, on which we all depend, is in our hands. We are using this opportunity to echo this message through the naming of this new genus of tiny wasp.

We hope to inspire global scientists to take another look in their collections to see if there is something small that could contribute to our collective understanding and therefore the future of our natural world. The name is a concatenation of ‘Attenborough’ and ‘Pedunculus’.

Attenboroughnculus tau De Ketelaere and Broad, sp. n.

Etymology: Named after the large, capital ‘T’ marking on the second metasomal tergite, with ‘tau’ being the Greek for ‘T’. A noun in apposition.

Abstract

A new species of the genus Gilen Reshchikov & van Achterberg, 2018 (Hymenoptera, Ichneumonidae, Ctenopelmatinae), G. principissa Chansri, Kerkig & Reshchikov, sp. nov., from Thailand is described and illustrated based on female specimens collected with Malaise traps. A molecular phylogenetic tree is presented based on DNA barcode sequences of representative Ctenopelmatinae, including sequences from both known Gilen species. The new species was recovered as sister to G. orientalis Reshchikov & van Achterberg, 2018 with 100% bootstrap support, but on a long branch. Comparison of the sequences revealed that they differ at 88 positions out of 658 (13.4%) possibly indicating that their lineages diverged between six and 13 million years ago.

[Entomology • 2025] Cotesia ginginensis • A New Species of parasitoid wasp (Hymenoptera: Braconidae: Microgastrinae) from Queensland, Australia

 

Cotesia ginginensis Fagan-Jeffries & Davies,

in Fagan-Jeffries, Davies et Howe, 2025.

DOI: doi.org/10.11646/zootaxa.5660.2.11

Cotesia Cameron, 1891 is the third largest genus of the braconid subfamily Microgastrinae, both in terms of described species  (>320  worldwide)  and  estimated  true  diversity  (1500+  species)  (Fernández-Triana et  al.  2020).  The  genus  is cosmopolitan  and  has  a  broad  host  range,  with  30  different  families  of lepidoptera  recorded  as  hosts,  and  with  many species acting as important biological control agents of pest lepidopterans (Fernández-Triana et al. 2020). The Australian Cotesia fauna was recently reviewed; there are 22 species currently known from the country, including several species introduced for biological control (Fagan-Jeffries et al. 2024; Fagan-Jeffries & Austin 2020).

 

Whilst there are likely to be many undescribed species of Cotesia in Australia and surrounding regions, we take the opportunity to add a single new species to the list of named biodiversity that was collected as part of a citizen science project, Insect Investigators. This citizen science project (insectinvestigators.com.au) ran in 2022 and involved 50 regional schools in Queensland, South Australia, and western Australia (Howe et al. 2025; insectinvestigators.com.au). Students and teachers ran Malaise traps on or near their school property, the samples were sorted and DNA barcoded, and a selection of specimens were sent to taxonomists to identify or include in current taxonomic projects. Two Queensland schools, gin gin State High School and Prospect Creek State School, each caught a single female specimen of a species in the genus Cotesia. Students and teachers at gin gin State High School collaborated with the authors to name the new species in 2023, and we here formally describe the species and raise the number of Cotesia from Australia to twenty-three.

Abstract

We describe and illustrate a new species of the aphidiine braconid genus Lipolexis Förster, Lipolexis khaoyaiensis sp. nov., from Thailand, using an integrative approach. Morphologically, the new species is similar to L. peregrinus Tomanović and Kocić, 2020, but molecular analysis showed clear separation of at least 27 independent Lipolexis lineages, only eight of which correspond to previously known species, plus the one which represents the new species described here. A molecular phylogeny based on all available barcodes support that the genus comprises two well supported clades, with L. khaoyaiensis sp. nov. being recovered in the gracilis species-group with strong support (100% ultrafast bootstrap). A modified section of the identification key to species of Lipolexis is added to include the new species. Reported host associations for each of the described species as well as a distribution map of all records of species plus provenances of all barcoded specimens is provided.

[Entomology • 2024] Syntretus perlmani • Drosophila are hosts to the First described Parasitoid Wasp (Hymenoptera: Braconidae) of Adult Flies

Syntretus perlmani Shaw & Ballinger,

in Moore, Amuwa, Shaw et Ballinger, 2024. 

DOI: 10.1038/s41586-024-07919-7

Abstract

Parasitoid wasps are exceptionally diverse and use specialized adaptations capable of manipulating the physiology and behaviour of host organisms. In more than two centuries since the first records of Drosophila-parasitizing wasps, nearly 200 described and provisional parasitoid species of drosophilids have been identified. These include endoparasitoids and ectoparasitoids, as well as species attacking larval and pupal hosts. Despite a deep history of research attention and remarkable biodiversity, a wasp species that attacks and develops inside the adult stage of a fly host has not been described previously. Here we report the discovery of a wasp species that infects the adult stage of fruit flies in the genus Drosophila, including one of the most deeply studied model organisms in biology, Drosophila melanogaster. Notably, this wasp can be easily collected from backyard fly baits and has a broad geographic distribution throughout the eastern USA. We document its life history and unique host interactions, including egg-laying into and larval emergence from adult flies, and provide protocols to raise wasps from wild-caught host flies. Our results emphasize the need for ongoing research investment in insect biodiversity and systematics. As parasitoid research continues to uncover unusual biology and supports fundamental mechanistic insights into immunity, metabolism, ecology, evolution and behaviour, we anticipate that this wasp’s association with the laboratory model organism, D. melanogaster, will provide new research opportunities across the life sciences.

a,b, The development of wasp larvae inside host flies (a) is accompanied by growth of wasp teratocytes (b, black arrows), which can be seen through the host abdominal cuticle and obstruct the view of the testes (b, white arrow). c, The second and following larval instars lack a head capsule and tail spike, and the final instar grows to nearly the length of the host fly (see Supplementary Video 2). d, Pupal development takes place within a white silken cocoon as is typical of euphorine wasps. e, Larval emergence is always from the abdomen and has been observed to occur between the second and third tergites (dorsolaterally) or laterally through a tear in the abdominal cuticle. f, The adult wasp (male shown) is small, yellowish brown and approximately 1.5 mm in length.

Differential diagnosis. Syntretus perlmani sp. nov is a tiny species that is distinct from other known Syntretus species by virtue of its small size (body length about 1.5 mm) and utilization of adult Drosophila flies as hosts. The antenna is shorter than the head and mesosoma combined, and there are 12–13 flagellomeres. Often the antenna has only 12 flagellomeres (the lowest number recorded for any North American Syntretus species).

Of the North American species, S. perlmani is most similar to Syntretus brevicornis Muesebeck, which also has a small body size and short antenna. Of the two species, S. perlmani is the smaller, with a body length of about 1.5 mm, as compared to 2.2 mm for ...

Etymology. This species is named after Steve Perlman (University of Victoria, British Columbia, Canada), in recognition of his contributions to research and mentorship in the field of Drosophila–parasite interactions.

 in Ranjith, Quicke, Reshchikov et Butcher, 2024. 

  DOI: 10.3897/jhr.97.121436

Abstract

The Ctenopelmatinae is one of the least explored groups of Ichneumonidae in South East Asia. We describe and illustrate an enigmatic new genus, Thaictenopelma Ranjith, Reshchikov & Quicke with the type species, T. splendida Ranjith, Reshchikov & Quicke, sp. nov., from a moderately high altitude site in northern Thailand. The new genus shows a unique set of morphological characters that distinguishes it from all other ctenopelmatine genera. The presence of a pair of complete latero-median as well as complete dorso-lateral carinae on the T2 are considered autapomorphic characters of the new genus. Affinities of the new genus within the Ctenopelmatinae are discussed and a note on the taxonomic placement is provided.

Diagnosis: Thaictenopelma gen. nov. can be separated from all other ctenopelmatine genera by its putatively autapomorphic carination pattern of T1 and T2. In particular, the pairs of complete latero-median and dorso-lateral carinae on T2 are completely unknown for the subfamily (Townes 1970). Additionally, the new genus can be distinguished from other ctenopelmatines by a combination of characters viz., the lower tooth of mandible being longer than upper tooth, propodeum with distinct carination, fore wing with rhombic areolet, T2 and T3 with posteriorly diverging groove basally, and T3 with distinct medio-basal protuberances.

Etymology: The generic name derived from a combination of ‘Thai’ for Thailand and ‘Ctenopelma’, type genus of the subfamily Ctenopelmatinae.

Thaictenopelma splendida Ranjith, Reshchikov & Quicke, sp. nov.,

Etymology: The species is named after the magnificent combination of morphological characters which are completely unknown from the members of the subfamily.

Abstract

A taxonomic study of the species of the Darwin wasp genus Eiphosoma Cresson, 1865 (Hymenoptera: Ichneumonidae: Cremastinae) from the department of Caquetá, Colombia, resulted in five new species being described: Eiphosoma caqueta sp. nov. (Type locality: Curillo, Caquetá), E. eneke sp. nov. (Type locality: San Vicente del Caguán, Caquetá) E. interpunctum sp. nov. (Type locality: Solano, Caquetá,), E. rumi sp. nov. (Type locality: Florencia, Caquetá) and E. sinecarenatum sp. nov. (Type locality: Florencia, Caquetá). With this paper, the number of Eiphosoma species from Colombia increases from three to 16. Eiphosoma bogan Gauld, 2000; E. dentator (Fabricius, 1804); E. dolopon Gauld, 2000; E. fluminense Costa Lima, 1953; E. fuzhi Gauld, 2000; E. macrum (Enderlein, 1921); E. minense Costa Lima, 1953 and E. tantalium Gauld, 2000 are recorded for the first time from Colombia. A dichotomous key to the Colombian species is presented.
