Item Austroconops Wirth and Lee, a Lower Cretaceous genus of biting midges yet living in Western Australia : a new species, first description of the immatures and discussion of their biology and phylogeny (Diptera, Ceratopogonidae). American Museum novitates ; no. 3449(New York, NY : American Museum of Natural History, 2004) Borkent, Art.; Craig, Douglas A. (Douglas Abercrombie)The eggs and all four larval instars of Austroconops mcmillani Wirth and Lee and A. annettae Borkent, new species, are described. The pupa of A. mcmillani is also described. Life cycles and details of behavior of each life stage are reported, including feeding by the aquatic larvae on microscopic organisms in very wet soil/detritus, larval locomotion, female adult biting habits on humans and kangaroos, and male adult swarming. Austroconops annettae Borkent, new species, is attributed to the first author. Cladistic analysis shows that the two extant Austroconops Wirth and Lee species are sister species. Increasingly older fossil species of Austroconops represent increasingly earlier lineages. Among extant lineages, Austroconops is the sister group of Leptoconops Skuse, and together they form the sister group of all other Ceratopogonidae. Dasyhelea Kieffer is the sister group of Forcipomyia Meigen + Atrichopogon Kieffer, and together they form the sister group of the Ceratopogoninae. Forcipomyia has no synapomorphies and may be paraphyletic in relation to Atrichopogon. Austroconops is morphologically conservative (possesses many plesiomorphic features) in each life stage and this allows for interpretation of a number of features within Ceratopogonidae and other Culicomorpha. A new interpretation of Cretaceous fossil lineages shows that Austroconops, Leptoconops, Minyohelea Borkent, Jordanoconops Szadziewksi, Archiaustroconops Szadziewksi, and Fossileptoconops Szadziewksi form a monophyletic group. Within this assemblage Leptoconops and Minyohelea are sister groups and Austroconops and Jordanoconops are monophyletic (Austroconops is possibly paraphyletic in relation to Jordanoconops). All are considered to be members of Leptoconopinae Noè and the subfamily Austroconopinae Borkent, Wirth and Dyce is a new synonym of Leptoconopinae. Extant and fossil distributional records suggest that Austroconops was displaced from its previously broad distribution by the emergence of Culicoides Latreille. Larval feeding on microorganisms is plesiotypic within the Ceratopogonidae and Chironomoidea, and living in small aquatic habitats is plesiotypic within each family of the Culicomorpha. Outgroup comparisons further suggest that diurnal feeding by adult females is plesiotypic within the Ceratopogonidae and Chironomoidea.Item Biting midges from Upper Cretaceous New Jersey amber (Ceratopogonidae, Diptera). American Museum novitates ; no. 3159(New York, N.Y. : American Museum of Natural History, 1996) Borkent, Art.Item Leptoconops (Diptera, Ceratopogonidae), the earliest extant lineage of biting midge, discovered in 120-122 million-year-old Lebanese amber. American Museum novitates ; no. 3328(New York, NY : American Museum of Natural History, 2001) Borkent, Art.As predicted by phylogenetic patterns, the genus Leptoconops Skuse is recorded for the first time from Lower Cretaceous Lebanese amber, dated at 120-122 million years. Two species are described as new: L. amplificatus, known from 1 male and 11 females, and L. antiquus, known from 2 females. These likely represent the earliest lineage(s) within the genus and are placed in a new subgenus, Palaeoconops. Previous analysis of Lebanese amber Ceratopogonidae (22 species, 126 specimens) indicated that these specimens represent a past community with high species diversity but with a low abundance of individual species. Leptoconops amplificatus is the first of 24 species of Ceratopogonidae known from this deposit to have intraspecific associations in a single piece of amber, likely reflecting their restriction to ancient beach habitats.Item The phylogenetic relationships of Cretaceous biting midges, with a key to all known genera (Diptera, Ceratopogonidae). (American Museum novitates, no. 3921)(American Museum of Natural History., 2019-02-25) Borkent, Art.The phylogenetic positions of Cretaceous species of Ceratopogonidae previously placed in the genera Archiculicoides Szadziewski, Protoculicoides Boesel, and Atriculicoides Remm are reappraised in light of synapomorphies. Character states are discussed in detail, supported by new photographs of Protoculicoides depressus Boesel, the description of Protoculicoides revelatus, n. sp., from Burmese amber, and a compilation of previously published illustrations. The recent article by Szadziewski et al. (2016) proposing that Protoculicoides and Atriculicoides are congeneric is shown to be inaccurate. At least three separate lineages are represented by species in these two genera, requiring a new genus, Gerontodacus (type species, G. succineus (Szadziewski)), to include some of them. Archiculicoides, Protoculicoides, Gerontodacus, Adelohelea Borkent and Alautunmyia Borkent remain undetermined to subfamily. As a result of phylogenetic and other taxonomic considerations, the following are new combinations: Gerontodacus krzeminskii (Choufani, Azar, and Nel), Gerontodacus punctus (Borkent), Gerontodacus skalskii (Szadziewski and Arillo), Archiaustroconops andersoni (Szadziewski, Ross, and Giłka), Atriculicoides ciliatus (Borkent), Atriculicoides hispanicus (Szadziewski and Arillo), Atriculicoides sanjusti (Szadziewski and Arillo) and Adelohelea burmitica (Szadziewski and Poinar). The following species are returned to the genera they were assigned to before Szadziewski et al. (2016): Atriculicoides cenomanensis Szadziewski and Schlüter, Atriculicoides dasyheleis Szadziewski, Atriculicoides globosus (Boesel), Atriculicoides incompletus Szadziewski and Schlüter, Atriculicoides macrophthalmus Remm, Atriculicoides sibiricus Szadziewski, Atriculicoides swinhoei (Cockerell), Atriculicoides szadziewskii Pérez-de la Fuente, Delclòs, Peñalver, and Arillo and Atriculicoides taimyricus Szadziewski. A key is provided to all Cretaceous Ceratopogonidae genera.Item A revision of the neotropical genus Baeodasymyia Clastrier and Raccurt (Diptera, Ceratopogonidae), with a discussion of phylogenetic relationships. American Museum novitates ; no. 3274(New York, NY : American Museum of Natural History, 1999) Borkent, Art.; Craig, Douglas A. (Douglas Abercrombie)The genus Baeodasymyia Clastrier and Raccurt, previously known only as adults from one extant and one fossil species, now includes four more extant species. The new species are described and named B. michaeli Borkent, n. sp., B. christopheri Borkent, n. sp., B. lydiae Borkent, n. sp., and B. gustavoi Borkent, n. sp. The larvae and pupae of B. michaeli and B. christopheri are also described and bionomic information provided for these and other species. Costa Rican species (n = 3) are all restricted to springs. Males and females of Baeodasymyia christopheri are strikingly sexually dimorphic in their thoracic pigmentation. A partially resolved cladogram suggests that the Dominican amber fossil species B. dominicana Szadziewski and Grogan is the sister group to all extant species, and that B. lydiae is the sister group to all remaining extant species (which are not further resolved). The presence of simple head capsule setae in larvae of Baeodasymyia indicates that this genus and its sister group Baeohelea Wirth and Blanton may be an early lineage within the Ceratopogonini. The Cretaceous genus Brachycretacea Szadziewski may be the sister group of Baeohelea + Baeodasymyia.Item World species of biting midges (Diptera, Ceratopogonidae). Bulletin of the AMNH ; no. 233([New York] : American Museum of Natural History, 1997) Borkent, Art.; Wirth, Willis Wagner."A checklist of all available names of Ceratopogonidae is provided, including author, date of publication, page number of original description, and country or territory of the type locality. All validly named taxa described until December 1995 are included, with many of those named in 1996, and some in 1997 also incorporated. The catalog provides a bibliography of all cited references and is fully indexed. Newly discovered homonymy generated 24 newly proposed species names. Seven new synonyms of species and one new generic synonym are proposed and two species have new status. Twenty-four new combinations are recognized. One species is transferred to the Chironomidae (Chironominae). A number of further nomenclatural changes and problems are discussed. Guides are provided for the location of type material of Ceratopogonidae. The number of species in each genus, both extant and fossil, is provided"--P. 5.
