This redescription is necessary because the original type has specimen has now been lost.

The new species can be separated from its only congener, <em>P. setosus</em> Sublette &amp; Wirth, 1972 from Jamaica, as it is slightly smaller with about 115 dorsocentrals compared to 56 in <em>P. setosus. </em>The inferior volsella is broadly subtriangular, while more lingulate in <em>P. setosus, </em>and the gonostylus has a small, but distinct megaseta and a subapical brush of spine-like seta, which apparently lack in <em>P. setosus.</em> The generic diagnosis is emended including the new species, and the systematic position is briefly discussed.</p> Trond Andersen, Amelie Höcherl, Annui Malla Sanz-laParra, Ruth H.

Further, the geographic origins of these sequences indicates that <em>C. vitellinus </em>is much more widely distributed than <em>C. javanus.</em> This interpretation is confirmed from the details of various descriptions, with differences particularly in the male hypopygium and the larval premandible. <em>Chironomus vitellinus</em> is also found in the New World in Florida and Puerto Rico, indicating that the species is probably distributed through most of the tropical region. However, <em>C. </em>sp. “Florida” of Epler (2001), known only as a larva, and with a multi-toothed premandible has been determined to be a separate species.</p> Jon Martin, John H.

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 <em>Kribiodorum belalong</em> 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 <em>Kribiodorum </em>Kieffer<em>.<span class="Apple-converted-space"> </span></em></p> Hongqu Tang, Peter S.

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.</p> Broughton A.
