Rivera-Vega L, Mikó I (2017) Know your insect: Malpighian tubules in Trichoplusia ni (Lepidoptera: Noctuidae). Research Ideas and Outcomes 3: e11827. DOI: 10.3897/rio.3.e11827
Abstract.—Malpighian tubules are mainly known to be involved in excretion. However, recent studies have begun to look into other potential roles including detoxification, immunity, host establishment, etc. In this case study, we observed the Malpighian tubules of the cabbage looper (Trichoplusia ni) using confocal laser scanning microscopy. We also discuss other functions that Malpighian tubules are known for (i.e. silk-like and gall-inducing secretions) as well as the similarities between Malpighian tubules and salivary glands in endoparasitic Hymenoptera.
Sandall, E. L. (2016) Bringing the George H. and Alice F. Beatty Odonata collection into the digital age. Argia 28(4): 33–34 (preprint – DOI: 10.6084/m9.figshare.4490552.v1)
Abstract.—A collection of over 60,000 odonate specimens can tell many stories. It can show the successful preservation of dragonflies and damselflies, as well as the differences in prey and habitat associations between taxa. The field notes can share observations and collecting details with those who may have never seen a particular species in the field. A collection of this size can also demonstrate the importance of natural history museums and their contents, enabling biodiversity research decades later. Of particular interest is the mobility of collections in the digital age, as evidenced through the U.S. NSF’s investment in Advancing Digitization of Biodiversity Collections (ADBC) grants, liberating natural history data on which novel research can be conducted. Over the past two years, I have worked with the collection of George H. and Alice F. Beatty at the Frost Entomological Museum at Penn State University in order to digitize the specimens in the collection, catalog them, and find ways to use their data through an NSF Thematic Collections Network (TCN) grant for digitization.
When it rains it pours. Here’s the latest open access publication, from István, former lab member Szabina Schwéger, and their colleagues!
Tang C-T, Mikó I, Nicholls JA, Schwéger S, Yang M-M, Stone GN, Sinclair F, Bozsó M, Melika G, Pénzes Z (2016) New Dryocosmus Giraud species associated with Cyclobalanopsis and non-Quercus host plants from the Eastern Palaearctic (Hymenoptera, Cynipidae, Cynipini). Journal of Hymenoptera Research 53: 77-162. DOI: 10.3897/jhr.53.9890
Abstract.—Our knowledge about gall wasps associated with the diverse East Asian oaks, Castanopsis and Cyclobalanopsis, is limited due to the lack of extensive field studies. Here, we describe twelve new oak gall wasp species, Dryocosmus cannoni Schwéger & Tang, D. caputgrusi Tang & Schwéger, D. crinitus Schwéger & Tang, D. harrisonae Melika & Tang, D. hearni Melika &Tang, D. hualieni Schwéger & Tang, D. konradi Tang & Melika, D. liyingi Melika & Tang, D. moriius Tang & Melika, D. quadripetiolus Schwéger & Tang, D. salicinai Schwéger & Tang, and D. taitungensis Tang & Melika, from Taiwan and mainland China. Seven newly described species induce galls on Quercus subgenus Cyclobalanopsis and five on other Fagaceae genus, Castanopsis. All of the new species concepts are supported by morphological and molecular data. We provide descriptions, diagnoses, host associations for the new species and an illustrated identification key to Eastern Palaearctic Dryocosmus species. We represent natural language phenotypes in a semantic format supported by biomedical ontologies to increase the accessibility of morphological data.
Here’s another product of our NSF ARTS grant, albeit not quite as major as our last publication! P.S. We love Biodiversity Data Journal and Pensoft’s ARPHA Writing Tool!
Mikó I, Masner L, Deans A (2016) Pteroceraphron Dessart new to the USA (Hymenoptera: Ceraphronoidea). Biodiversity Data Journal 4: e9261. DOI: 10.3897/BDJ.4.e9261
Background.—Pteroceraphron is a monotypic genus that can be recognized by its unique, lanceolate wing shape. Until now the only described species, Pteroceraphron mirabilipennis Dessart 1981, was known only from specimens collected in Canada.
New information.—Here, for the first time, we report Pteroceraphron mirabilipennis Dessart 1981 specimens collected in the USA. We also provide an extended diagnosis.
Our most recent ARTS product is a doozy. Check it out! Also, we love PeerJ!
Mikó I, Trietsch C, Sandall EL, Yoder MJ, Hines H, Deans AR. (2016) Malagasy Conostigmus (Hymenoptera: Ceraphronoidea) and the secret of scutes. PeerJ 4: e2682 DOI: 10.7717/peerj.2682
Abstract.—We revise the genus Conostigmus Dahlbom 1858 occurring in Madagascar, based on data from more specimens than were examined for the latest world revision of the genus. Our results yield new information about intraspecific variability and the nature of the atypical latitudinal diversity gradient (LDG) observed in Ceraphronoidea. We also investigate cellular processes that underlie body size polyphenism, by utilizing the correspondence between epidermal cells and scutes, polygonal units of leather-like microsculpture. Our results reveal that body size polyphenism in Megaspilidae is most likely related to cell number and not cell size variation, and that cell size differs between epithelial fields of the head and that of the mesosoma. Three species, Conostigmus ballescoracas Dessart, 1997, C. babaiax Dessart, 1996 and C. longulus Dessart, 1997, are redescribed. Females of C. longulus are described for the first time, as are nine new species: C. bucephalus Mikó and Trietsch sp. nov., C. clavatus Mikó and Trietsch sp. nov., C. fianarantsoaensis Mikó and Trietsch sp. nov., C. lucidus Mikó and Trietsch sp. nov., C. macrocupula, Mikó and Trietsch sp. nov., C. madagascariensis Mikó and Trietsch sp. nov., C. missyhazenae Mikó and Trietsch sp. nov., C. pseudobabaiax Mikó and Trietsch sp. nov., and C. toliaraensis Mikó and Trietsch sp. nov. A fully illustrated identification key for Malagasy Conostigmus species and a Web Ontology Language (OWL) representation of the taxonomic treatment, including specimen data, nomenclature, and phenotype descriptions, in both natural and formal languages, are provided.

Abstract.—Two new species, Dvivarnus elektrolythron Talamas & Mikó, sp. n. and D. mikuki Talamas & Mikó, sp. n. are described. The genus is redescribed and a key is provided to separate Dvivarnus from other groups in Teleasinae with mesoscutellar spines.
Burks KN, Mikó I, Deans AR (2016) Dendrocerus mexicali (Hymenoptera, Ceraphronoidea, Megaspilidae): Novel antennal morphology, first description of female, and expansion of known range into the U.S. ZooKeys 569: 53-69. doi: 10.3897/zookeys.569.6629
Abstract.—Dendrocerus mexicali has been described by Paul Dessart from a single male specimen collected in Mexico. Using 87 newly identified specimens we expand the known range to include the Southwestern United States and Florida, provide an expanded description of the species, and provide the first record of the female. We also use confocal laser scanning microscopy and in vitro hydrostatic pressure changes to investigate the functional morphology of apparently unique basally flexible antennal branches.
