• Correcting a mistake: Limnophyes stagnum Namayandeh, Guerra & Ram, 2024 is not conspecific with Limnophyes sp. 14ES
  In this communication, we report on correcting DNA barcoding records of Limnophyes stagnum Namayandeh, Guerra & Ram, 2024. The five sequences we submitted to BOLD and published in Namayandeh et al. (2024) under L. stagnummatch the CO1 sequences of Limnophyes sp. 14ES and the two species are not conspecific. Both species were collected from the type locality of L. stagnum but at different times with a misassumption that both species represent a single taxon. We have corrected our records in BOLD, replacing the names of the five sequences with Limnophyes sp. 14ES. Additionally, we obtained and uploaded a single CO1 sequence of L. stagnum in BOLD and incorporated it into new molecular analyses reported here. Based on our results, the closest sequences to L. stagnum were those of Limnophyes natalensis (Kieffer, 1914). The minimum K2P distance of L. stagnum with L. natalensis was 10.0% (average 11.4%), large enough to support the delimitation of L. stagnum sp. nov. from L. natalensis. Further discussion on the morphological differences of the two species and those of L. stagnum and Limnophyes sp. 14ES are provided.

• Redescription of adults of Kribiodorum belalong Cranston (Diptera, Chironomidae, Chironomini) from Gunung Mulu National Park, Sarawak, Malaysia

  The adult male of Kribiodorum belalong Cranston (Diptera: Chironomidae) was described only from a teneral adult specimen along with pupae. Certain key characters are unavailable or unmeasurable in the teneral form, e.g., wing dimensions, abdominal coloration pattern, and fine details of the hypopygium including the dorsal shape of the anal point. Here we redescribe and figure the adult male, and describe and illustrate the adult female of Kribiodorum belalong for the first time, both based on specimens recently collected in Gunung Mulu National Park, Sarawak, Malaysia. We provide some comments on the putative phylogenetic position of Kribiodorum Kieffer.

• Description of the pupa of "Diamesinae Genus P" Doughman, 1985 (Diptera: Chironomidae), with comments on habitat, distribution and further characterization of the larva

  The pupal stage of “Diamesinae Genus P” Doughman, 1985 is described from specimens collected in northwest Georgia, USA. The pupa is recognized as Diamesinae by dorso- central thoracic setation with no prealar setae and lack of hooklets on tergite II. Also, the anal lobe has apical short tubercles and 3 hooked macrosetae with very distinctive apices. However, leg sheath arrangement differs slightly from described Diamesini with fore and mid leg sheaths directed laterally at the wing apex and frontal setae are lacking, but for now this is considered variation within the tribe. The strikingly unusual larva is recognized as Diamesinae by the annulate third antennal segment as well as characteristics of the premento-hyphoryngeal complex. The larva fits within Diamesini in the most recent keys of Holarctic genera. Currently known distribution, habitat and additional larval morphological details are noted.
