[Entomology • 2026] Attenboroughnculus tau • A New Genus of Pedunculinae (Hymenoptera: Ichneumonidae) from Chile and A Key to the World Genera


Attenboroughnculus tau De Ketelaere and Broad,

in De Ketelaere, Pullar et Broad, 2026.  

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] Montichneumon immortalibestia • A New Genus of Ichneumoninae (Hymenoptera: Ichneumonidae) from the high mountains of Taiwan


 Montichneumon immortalibestia Chen & Kikuchi, 

in Chen, Kikuchi et Shiao, 2025  

Abstract
A new genus and species, Montichneumon Chen & Kikuchi gen. nov. and Montichneumon immortalibestia Chen & Kikuchi gen. et sp. nov., are described from the high mountains of Taiwan. This new genus is identified as belonging to the Amblyteles genus-group (previously known as subtribe Amblytelina, tribe Ichneumonini). The status of the new genus is confirmed based on morphological comparison and a multigene phylogeny using concatenated 28S and COI sequences. Montichneumon can be distinguished from other related genera by its enlarged second segment of maxillary palps, smooth and sparsely punctate postpetiole, weakly convex scutellum without lateral carina, and narrow, elongate gastrocoelus. The new genus is compared with morphologically similar genera Achaius Cameron, 1903, Achaiusoides Tereshkin, 2011, Diphyus Kriechbaumer, 1890, Hepiopelmus Wesmeal, 1845, Limerodops Heinrich, 1949, Serratichneumon Riedel & Sheng, 2023, and Tricholabus Thomson, 1894. A diagnostic key to these morphologically similar genera of the Amblyteles genus-group is provided, and the generic position of this new genus is also discussed.

Keywords: Darwin wasp, generic placement, molecular phylogeny, high-elevation, taxonomy


Montichneumon Chen & Kikuchi gen. nov. 

Etymology: The generic name ‘Montichneumon’ is derived from the Latin dative singular noun ‘monti-’ (‘mountain’) plus ‘ichneumon’, reflecting that this new genus was collected from the high-elevation mountain of its type locality in Taiwan. The gender is masculine.


Montichneumon immortalibestia Chen & Kikuchi gen. et sp. nov.

Etymology: The specific name ‘immortalibestia’ is derived from the Latin words ‘immortali-’ (‘immortal’) plus ‘bestia’ (‘beast’), meaning ‘the undying beast’. The name refers to the superhero character ‘Wolverine’ from the Marvel Comics series ‘X-Men’, who has the abilities of regeneration and beast-like retractable metal claws, as the yellow and black color pattern of this species resembles the costume of this character. Specific name is a noun in apposition.

[Entomology • 2025] Losgna occidentalis • Rediscovery and Description of A New Species of Losgna (Cameron 1903) (Hymenoptera: Ichneumonidae): Reviving a forgotten ichneumonid Genus in India


Losgna occidentalis 
Om Chaudhary & Reinisch, 2025

 
Abstract
The Darwin wasp genus Losgna (Cameron, 1903) (subfamily Ichneumoninae), is poorly documented in India, with no new species described since Heinrich’s work in 1965. Here we rediscover the genus in India and describe a new species collected from an urban dry scrub forest in Chandigarh. A taxonomic key for the identification of Indian Losgna is provided along with the illustrations of the new species and Generitype. The study significantly extends the known distribution of Losgna in the Oriental region and highlights the under-explored diversity of Ichneumoninae in India and the need for further taxonomic research.

[Entomology • 2024] Thaictenopelma splendida • A New enigmatic Genus of the ichneumonid (Hymenoptera: Ichneumonidae: Ctenopelmatinae) from northern Thailand


Thaictenopelma splendida Ranjith, Reshchikov & Quicke, 
 
 in Ranjith, Quicke, Reshchikov et Butcher, 2024. 

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.

[Entomology • 2019] Molecular Phylogeny of Ateleutinae (Hymenoptera: Ichneumonidae): Systematics and Biogeography of A Widespread Parasitoid Wasp Lineage


 Duwalia perula Santos, 

in Santos, Alvarado, Sääksjärvi, et al., 2019. 

 
Abstract
The phylogeny of the ichneumonid parasitoid wasp subfamily Ateleutinae is investigated based on molecular data from five genes. A total of 36 species are included in the ingroup. Maximum likelihood analyses recovered a strongly supported monophyletic clade circumscribing the subfamily Ateleutinae. Five main clades were recovered in the subfamily, but relationships between these clades were mostly poorly supported. A new genus is identified and described: Duwalia Santos gen. nov. from Australia, which corresponds to the earliest known diverging lineage of Ateleutinae. Duwalia perula Santos sp. nov. is described and illustrated. The genus Ateleute is shown to be paraphyletic with respect to Tamaulipeca, but further studies with more intense sampling of the Neotropical fauna are needed in order to provide a comprehensive classification of the genera within this subfamily. Ateleute boitata Santos sp. nov., a morphologically aberrant species from South America, is described to highlight the morphological diversity in the genus. All Old World species of Ateleute are recovered in a single clade. Ateleute grossa is newly recorded as a parasitoid of Oiketicus kirbyi (Lepidoptera: Psychidae). Diagnoses and identification keys to the genera of Ateleutinae are provided.

A, female habitus. B, clypeus and mandible. C, male habitus. D, propodeum. E, ovipositor sheath. F, metasomal T1. G, ovipositor tip.

DUWALIA SANTOS, GEN. NOV.

Etymology: The genus name stems from the Australian aboriginal word ‘duwal’, meaning a short spear with two barbs, and also a name for a clan from the Dua moiety. The name is a reference to the short ovipositor of D. perula, with ridges on the dorsal valve. Duwalia is to be treated as a feminine noun.  

DUWALIA PERULA SANTOS, SP. NOV.

Etymology: ‘Perula’ is a Medieval Latin form for ‘pearl’, apparently derived from ‘pernula’, diminutive of ‘perna’ (the brown mussel); in reference to the type locality, Pearl Beach, in Australia. The name is to be treated as a noun in apposition.

Mr. Mena is known for his support of important causes and has supported many NGO’s in Colombia that have an important social impact.


Dolichomitus orejuelai Araujo & Pádua, sp. nov.

Diagnosis: Dolichomitus orejuelai sp. nov. may be distinguished from other Neotropical species by the combination of the following characteristics: head and mesosoma mostly reddish black; metasoma mostly yellowish brown with anterior half of tergite I dorsally, posterior margin of tergites II–V, a semicircular dorsal spot based on the anterior margin of tergite V, tergites VI–VIII reddish black; face with abundant setiferous punctures; malar space 0.30× as long as basal mandibular width; mandible bidentate, 1.40× as long as basal width; hind leg with femur ca. 5.50× as long as height; wings yellowish, pterostigma light brown; areolet not petiolated; dorsolateral carinae of first metasomal tergite present on petiole and stronger on postpetiole; posterior half of tergite II and tergites III–V densely and strongly punctuate; ovipositor sheath ca. 1.10× as long as body, and ca. 3.00× as long as hind tibia.

Etymology: The specific epithet is a tribute to Jorge Enrique Orejuela Gardner, National Geographic 2007 Buffet prize winner for his work over three decades in Colombia on conservation education, protected area management and sustainable development. His accomplishments include the establishment of the cloud forest nature reserve La Planada, also helped establish Utría and Gorgona Island national parks, and the Quindío Basin and Calima River nature reserves. His mentoring for the creation of the Mesenia-Paramillo nature reserve was key to the success of this conservation project.



Dolichomitus pimmi Araujo & Pádua, sp. nov.

Diagnosis: Dolichomitus pimmi sp. nov. may be distinguished from other Neotropical species by the combination of the following characteristics: general pattern of general color (orange yellow with various specifics black marks; wings yellowish with strongly contrasting apical darkened area, pterostigma light brown; areolet not petiolate; malar space 0.30× as long as basal mandibular width; mandible bidentate, 2.55× as long as basal width (front view); tergite I ca. 2.20× as long as posteriorly wide; ovipositor sheath ca. 0.90× as long as body, and ca. 3.00× as long as hind tibia.

Etymology: The specific epithet is in honor of Stuart Pimm, Doris Duke Chair of Conservation Ecology in the Nicholas School of the Environment at Duke University. Winner of the 2006 Heineken Prize for Environmental Sciences, awardee of the Tyler Prize for Environmental Achievement in 2010, and recipient of the 2019 International Cosmos Prize – among the most prestigious honors in the environmental field – for his research on endangered species and his work to help reverse species’ declines by protecting their shrinking habitats. His support of the Mesenia-Paramillo nature reserve conservation project to restore areas and reconnect forest fragments has been invaluable.


Dolichomitus rendoni Araujo & Pádua, sp. nov.
  
Diagnosis: Dolichomitus rendoni sp. nov. may be distinguished from other Neotropical species by the combination of the following characteristics: malar space 0.35× as long as basal mandibular width; mesosoma mostly red with the tegula white; wings yellowish, pterostigma dark brown; areolet slightly petiolate; fore leg with a white concavity on it postero-dorsal margin; fore and mid legs mainly white; hind wing with vein cu-a ca. 1.20× as long as proximal abscissa of CU; metasoma mostly reddish black with ventro-lateral spots on tergites III–IV, lateral of tergites V–VIII red (except for the posterior margin of tergites V and VI laterally reddish black); posterior margin of tergite I–VII with a white band dorsally (small and narrow on tergite I); posterior membranous section of first metasomal sternite ca. 0.60 of length of tergite; ovipositor sheath ca. 0.90× as long as body, and ca. 2.90× as long as hind tibia.

Etymology: The specific epithet is in honor of Ubiel Rendon, park ranger at the Mesenia-Paramillo nature reserve. A La Mesenia village native and once an avid hunter, his knowledge of the surrounding forests has been key for monitoring wildlife and helping with long-term studies using camera traps. He has made several important contributions to the scientific world, finding multiple new species of amphibians, reptiles and orchids at the reserve, including this Darwin wasp named in his honor.
