DISTRIBUTION AND HABITAT: The genus Dasyhelea is known from 609 species from every Region worldwide (Borkent 2014, Díaz, et al. 2014). Immatures are known from a wide array of small aquatic habitats, primarily from algal growth on damp soil or other wet substrates, wet moss, algae or moss at the margins of standing or running water and amongst floating vegetation (including algal mats). As one would expect with a species rich genus, immatures occur in a wide array of other microhabitats but all of these are small aquatic (or soaking wet) habitats such as from Pistia, wet decomposing vegetation, ant refuse piles (of Atta), mining floating leaves of Salvinia, sap from tree wounds, wet woodland leaf packs, small ground or rock pools, phytotelmata, margins of extreme saline pools, hot springs, intertidal zone, marine splash-zone, salt marshes, small artificial habitats such as rain gutters, and attacking tobacco seedlings grown hydroponically. Larvae appear to require water on their bodies to survive, while pupae either remain immersed in media or crawl upward to drier substrate.
Münchberg (1961) studied the function of the respiratory organs of D. flavifrons (as D. versicolor) under experimental conditions, removing either one or both of the respiratory organs or applying sealant to the pores. His questionable approach resulted in death for those with both respiratory organs removed and very little survivorship in those with one removed. He suggested that some respiration may occur through the terminal processes but this is clearly not possible (there is no opening posteriorly). Some young pupae could remain submerged for substantial periods of time indicating they likely extract oxygen from the surrounding water.
TAXONOMIC DISCUSSION: There are 90 species of Dasyhelea known as pupae (Tables 2–3) and there is a high level of morphological differentiation between many of them. Clearly, there are numerous synapomorphies waiting to be interpreted. Furthermore, this genus is extremely species rich, with many undescribed species, and pupal morphology will certainly assist in interpreting these.
Even though there are a goodly number of named species with described pupae, it is clear that the identity of some of them is uncertain. For example, Thienemann (1925) recognized the pupae of D. flavifrons and five other species (D. brevitibialis, D. lignicola, D. obscura, D. sensualis, D. versicolor) now all considered to be one species (the latter as synonyms of D. flavifrons). Similarly, Lenz (1934) noted differences between the pupae of D. flavifrons and some of these same taxa. Some of the differences noted are likely valid indicators of species differences, although it is now uncertain what adults were actually reared and associated. Mayer (1934a) also describes differences between species now considered synonyms (e.g. D. modesta with its synonyms D. inclusa and D. longipalpis).
Mayer (1934a) and Lenz (1934) provided a key to the 19 European species known at that time and Thienemann (1925) has a key to some species from northern Germany. The pupae of 11 Nearctic species were described and illustrated by Waugh & Wirth (1976), showing significant differences between them but they did not provide a key. The campaniform sensilla DA-2-H is present in these species but were not illustrated. Mayer (1934c) described and keyed 13 species from Indonesia indicating and illustrating detailed differences between their dorsal apotomes, respiratory organs, and the shape and chaetotaxy of segment 9. Mayer (1934c) showed the dorsal apotome of D. insons with DA-2-H as a seta (so there are two setae on a single tubercle), which would be unique within the genus. All other species I studied had one seta and one campaniform sensillum. Wirth & Beaver (1979) described and keyed the unusual pupae of five species of Dasyhelea found in Nepenthes (monkey cup) in southeast Asia.
Fossil pupae of six species were described (or redescribed) by Pierce (1966). Although the specimens were not reexamined here, based on the form of the terminal processes (divided), they are clearly correctly assigned to genus. Grimaldi & Engel (2005:45) include a photograph of two silicified pupae identified as 'ceratopogonid midges' and which are likely members of Dasyhelea, based on their size and the presence of distinctive shelf-like tubercles nearly encircling the abdominal segments.
Scanning electron photomicrographs of pupae were published by Ronderos et al. (2004), Dominiak (2012) and Díaz et al. (2013). Park & Downing (2001) published an scanning electron photomicrograph of the terminal abdominal segments of the fossil Miocene species D. australis, showing how a similar approach could be used to better understand other fossil Dasyhelea species.
Pupae of Dasyhelea have a reduced number of thoracic sensilla and the naming of the two setae as D-1-T and D-2-T is arbitrary as they may not be homologous to those specific setae in other ceratopogonids.
Most species of Dasyhelea have abdominal segments with a typical and characteristic transverse arrangement of lower, broad tubercles (Fig. 56C). A few species found in Nepenthes in southeast Asia, however, have sensilla on somewhat to markedly elongate tubercles (Wirth & Beaver 1979). An undescribed species from Australia (Running Creek) also had abdominal sensilla D-4 IV, D-8 IV, L-2 IV, L-3 IV, L-4 IV, V-7 IV on markedly elongate tubercles. D-4-IV in these taxa was represented by a seta (rather than a campaniform sensillum present in other Dasyhelea).
