  • Verifying Australian Nilotanypus Kieffer (Chironomidae) in a global perspective: molecular phylogenetic analysis, new species and emended generic diagnoses

    Molecular data support two distinct species of Nilotanypus Kieffer (Chironomidae: Tanypodinae) differentiated on morphology in all stages. Each is described as Nilotanypus haplochelus new species and Nilotanypus ctenochelus new species respectively. Morphological differentiation is stronger in the larva and pupa, with adult stages less well differentiated, as seems usual in the genus. Both species are distributed widely across the Australian continent, but seemingly absent from offshore islands and Tasmania. A tendency towards lotic psammophily (sand-dwelling) is evident, with sympatry at some tropical / subtropical locations. Additional molecular data from non-Australian taxa indicates that N. ctenochelus is sister to all other sampled taxa and N. haplochelus to an undescribed species from oriental China. Review of all stages of several non-Australian species requires revised generic diagnoses, and, critically, recognition of Pentaneura comata Freeman 1953 as synonymous with the type of the genus, Nilotanypus remotissimus Kieffer 1923 (new synonym).

  • A home at last! Changania choui Tseng, 1965 belongs to Thienemanniella Kieffer, 1911 (Diptera: Chironomidae: Orthocladiinae)

    The midge Changania choui Tseng, 1965 (Insecta, Diptera, Nematocera), originally described in the family Cecidomyiidae and recently transferred to the Ceratopogonidae, is recognised as an adult female in the Chironomidae, subfamily Orthocladiinae. The type material is missing, and the published description and illustrations are limited. Although the genus name Changania Tseng, 1965 becomes a new junior synonym of Thienemanniella Kieffer, 1911, Thienemanniella choui (Tseng 1965), new combination, should be treated as a nomen dubium.

  • Propsilocerus Kieffer, 1923 shares morphological synapomorphies with Prodiamesinae

    In their comprehensive analysis Cranston et al. (2012) quite unexpectedly recovered a monophyletic Orthocladiinae, except that Propsilocerus Kieffer, 1923, was recovered as a representative of Prodiamesinae. In this short communication I show that Propsilocerus shares morphological synapomorphies with other Prodiamesinae – namely (i) an indirect tracheal connection of the pupal thoracic horn to the adult spiracle and (ii) a parallel-sided rami of female gonapophysis IX.

  • Dicrotendipes sinicus Lin & Qi, sp. n. (Diptera: Chironomidae)

    The name Dicrotendipes sinicus was originally proposed in 2018, but the requirements of the International Code of Zoological Nomenclature were not fulfilled to make the name available. We here re-propose the name with full Code compliance and redescribe and illustrate all life stages of the species to make the name available.
