Cryptic species present challenges across many subdisciplines of biology. Not all “cryptic” species, however, are truly cryptic; many are simply underexplored morphologically. We examined this idea for the Antistrophus rufus species complex, which previously contained three species thought to be morphologically cryptic. To determine whether the A....

... Morphological terminology primarily follows the Hymenoptera Anatomy Ontology (Yoder et al. 2010) and the Phenotype and Trait Ontology (PATO Curators 2023). We selected morphological characters for Aulacideini from recent works on herb gall wasps, especially Melika (2006), Nieves-Aldrey (2022), and Nastasi et al. (2024b). Terms relating to gall phenotypes and structure were drawn from Deans et al. (2023. ...
... Lastly, Soparia greatly resembles some species of the Nearctic genus Antistrophus Walsh, 1869. While species of Antistrophus exhibit striate-reticulate sculpture on the mesopleuron, they all lack a conspicuous setose patch on second metasomal tergite, and all have an open marginal cell (Nastasi et al. 2024a(Nastasi et al. , 2024b. Antistrophus is also exclusively Nearctic in distribution and induces galls only on plants native to the region (Nastasi & Deans 2021, Nastasi et al. 2024b. ...

We describe three new aulacideine herb gall wasp species (Hymenoptera: Cynipidae: Aulacideini) from Kyrgyzstan, a country from which only two Aulacideini species were previously known. One of our new species represents a new genus, which we describe here as Soparia oshensis Nastasi gen. and sp. nov. We describe Panteliella rugosa Nastasi sp. nov., representing a new genus record for Kyrgyzstan. To further facilitate species recognition in Panteliella, we redescribe the genus and the species P. fedtschenkoi; provide a translated description of P. bianchii Vyrzhikovskaya, 1962; comment on complications affecting this genus; and provide a key to Panteliella species. Lastly, we describe Isocolus barakus Nastasi sp. nov., a species with morphology atypical of Isocolus. We provide a key to the Kyrgyz genera of Aulacideini to ensure that they remain diagnosable for future study. Our findings illustrate the continued unveiling of a diverse herb cynipid fauna in Central Asia and a need for further taxonomic study in the region.
... Additionally, especially diverse are communities associated with Antistrophus gall wasps, hymenopterans that induce the formation of modifed plant structures within which their progeny feed and develop. Recent studies suggest that these communities are composed of specialist gall inducers that induce galls on one or several rosinweed species, as well as both specialist and generalist parasitoids and facultative predators that feed on gall wasps [3,6,11]. ...
... To facilitate continuing research in rosinweed systems, we provide here a catalog of endophytic insect species that have been reported from rosinweed species. Tis study constitutes the frst comprehensive attempt to defne the diversity of endophytic insects associated with rosinweeds, although several studies have addressed subsets of rosinweed-associated arthropods [3,4,6,11]. While some resources, such as the Illinois Wildfowers Database (https:// www.illinoiswildfowers.info/plant_insects/database.html), ...
... Because the four main Silphium species yielded around 40 insect species, it seems likely that surveying and rearing insects from other rosinweed species will likely yield many new records of endophytic insect species, as well as new host plant records for known polyphagous insects. In line with this observation, Nastasi et al. [11] suggest a high likelihood of cospeciation between rosinweeds and their specialist gall wasps. Should this pattern continue to be observed, especially in other rosinweed insect groups beyond gall wasps, there could be many additional species awaiting discovery in rosinweed systems. ...
Endophytic insects, including gall insects and leaf miners, are prominent in both natural and agricultural plant communities. We catalog the endophytic insect fauna in North America that are known to associate with rosinweeds (Silphium L., Heliantheae, Asteraceae). We provide details on host plant species, brief descriptions of insect associations, and known distributions of their association with Silphium species. We report associations with rosinweeds for 41 insect species from 18 families across four insect orders and detail the host plant tissue where these insects occur. The complex community we describe suggests that a further study of rosinweed endophytic insects could be useful to understanding evolution of host-plant preferences and Silphium species boundaries.
... We found them to be morphologically identical, including the dimensions of several structures (F1 and F2, the marginal cell, and the ocellar triangle), thus suggesting that both sets of specimens are conspecific. These characters are known to be consistent for individuals of a given species but usually different between congeners according to recent studies of aulacideine herb gall wasps (Nastasi et al. 2024b). ...
... The Neaylax specimens from Winnipeg ( Fig. 1) are N. verbenacus based on the diagnostic characters given by Nieves-Aldrey (1988, 2001 and Melika (2006), particularly the lack of a strong median mesoscutal impression, the complete notauli (Fig. 2), the open fore wing marginal cell, and the lack of a pilose patch on the second metasomal tergite. This combination of characters distinguishes Neaylax from all other Nearctic Aulacideini (Nastasi et al. 2024a(Nastasi et al. , 2024b. Our specimens perfectly agree with the SEM images in Nieves-Aldrey (2022), especially in characters of the mesosoma. ...
... Other terms relating to phenotypes are derived from the Phenotype and Trait Ontology (PATO curators 2023). We selected morphological characters for examination and description from various recent taxonomic studies concerning herb gall wasps (Melika 2006;Azmaz & Katilmiş 2020;Nieves-Aldrey 2022;Tavakoli et al. 2022;Nastasi et al. 2024b).

We describe Aulacidea manchuria Nastasi sp. nov., a new species of herb gall wasp from China and the second species of Aulacidea Ashmead, 1897 to be described from the country. Based on morphological data, A. manchuria belongs to the Aulacidea hieracii group, which is known to induce galls on the stems, leaves, and stolons of Hieracium L. and Pilosella Hill; we provide a key to Eastern Palearctic females of this species group to better enable identification of these species. We discuss records of herb gall wasps from China, the recognition of hawkweed gall wasp species, and further issues with taxonomy of this species group and of Aulacidea.
We describe new species in the genus Ceroptres Hartig, 1840 (Hymenoptera: Cynipidae: Ceroptresini) represented by voucher material sequenced by Ward et al. (2024). We describe 22 new species, all authored by Nastasi, Smith, & Davis: C. anansii sp. nov., C. anzui sp. nov., C. bruti sp. nov., C. curupira sp. nov., C. daleki sp. nov., C. dandoi sp. nov., C. demerzelae sp. nov., C. iktomii sp. nov., C. jabbai sp. nov., C. jarethi sp. nov., C. lokii sp. nov., C. lupini sp. nov., C. mallowi sp. nov., C. promethei sp. nov., C. sandiegoae sp. nov., C. selinae sp. nov., C. soloi sp. nov., C. songae sp. nov., C. swiperi sp. nov., C. thrymi sp. nov., C. tikoloshei sp. nov., and C. zorroi sp. nov. After our taxonomic treatment, the genus Ceroptres includes 43 species, all but three of which are known from North America. Among our new species are two reared from cecidomyiid midge galls, an association previously recorded but without valid taxonomic association. We provide new records for two additional previously described species; we record C. ensiger (Walsh, 1864) from Pennsylvania and confirm characters for the male, and we record C. lanigerae Ashmead, 1885 from Texas. We also examined several putative species corresponding to either C. cornigera Melika & Buss, 2002 and/or C. frondosae Ashmead, 1896, which we regard as a species complex that requires elucidation in future studies. To enable further studies on Ceroptres, we provide an updated key to North American females. Overall, we find that species of Ceroptres are host specialists associated with a single host gall species or several galls that are phylogenetically or ecologically related. We suggest that there are many North American species of Ceroptres, possibly hundreds, still awaiting collection and characterization.
