The Afro–Oriental Genus Yaeprimus Sasa et Suzuki (Diptera: Chironomidae: Chironomini): Phylogeny, New Species and Expanded Diagnoses

Abstract

Expanded generic diagnoses of all life stages of Yaeprimus Sasa et Suzuki, 2000 (Lunditendipes Harrison, 2000, syn. n.) are given. Yaeprimus tropicus comb. n. is redescribed as an adult based on type material. Additionally, a new species Y. balteatus sp. n. from Oriental China is described based on the adult male and pupa. The phylogenetic position of Yaeprimus within Chironomini and the validity of the new species are explored based on concatenated five genetic markers (18S, 28S, CAD1, CAD4, and COI-3P) through both mixed–model Bayesian inference and maximum likelihood methods. The results strongly support Yaeprimus as sister to Imparipecten Freeman, 1961, which counters a previously proposed systematical position based solely on morphology.

Life histories of Paucispinigera Freeman, Paraborniella Freeman and Paratendipes Kieffer (Diptera: Chironomidae) with phylogenetic considerations

“…Other putatively related genera sampled for molecular data, namely Apedilum Townes, and Zavreliella Kieffer + Lauterborniella Thienemann & Bause form a well-supported cluster as sister to Skusella Freeman + Conochironomus Freeman, in turn sister to Paratendipes Kieffer + Paralauterborniella Lenz. This inclusive clade, informally termed the 'Microtendipes group', finds subsequent support including from an expanded molecular analysis by Han et al (2020), although it was not recovered in the large and densely sampled morphological analysis of Andersen et al (2017). Paratypes (collected Cranston, deposited ANIC, unless otherwise stated).…”

DNA barcodes and morphology reveal new species within the Rheotanytarsus guineensis species group from China (Diptera: Chironomidae)

“…The DNA barcode, corresponding to the 658‐bp fragment of the 5′‐end of the mitochondrial gene cytochrome c oxidase I (COI), has been identified as the core of a global bio‐identification system at the species level and it has been considered the most commonly used marker for identifying nonbiting midge species delimitation (Hebert, Cywinska, et al, 2003; Hebert, Ratnasingham, et al, 2003). COI barcodes have provided important evidence to confirm new species (Anderson et al, 2013; Ekrem et al, 2018; Gadawski et al, 2022; Han et al, 2020, 2023; Kodama et al, 2018; Lin et al, 2015, 2018, 2019, 2020; Lin, Jiang, et al, 2021; Lin, Mo, et al, 2021; Lin et al, 2021; Song et al, 2018; Stur et al, 2019). In the R. guineensis group, DNA barcodes for only one species ( Rheotanytarsus ringei Lehmann, 1970) were reported in past studies.…”

New Mitogenomes of the Polypedilum Generic Complex (Diptera: Chironomidae): Characterization and Phylogenetic Implications

“…The Polypedilum generic complex belongs to the tribe Chironomini of the subfamily Chironominae, containing Ainurusurika , Endochironomus , Endotribelos , Phaenopsectra , Polypedilum , Sergentia , Stictochironomus , Synendotendipes , Tribelos , and Zhouomyia [ 14 , 15 ]. Species of this group are mainly distributed in neotropical rivers [ 16 ].…”

“…Their diversity of larval habitat, which includes wood-mining, and aquatic habit therein, also render them an important group for studying evolutionary biology [ 12 , 17 ]. Several taxonomy and molecular studies have examined the phylogenetic relationships of the Polypedilum generic complex [ 15 , 18 , 19 ], but uncertainties in classification schemes among these groups still persist [ 19 , 20 , 21 ].…”
