“…The oldest record for Sisyridae is from the Cretaceous (Makarkin & Perkovsky, ; Perkovsky & Makarkin, ). Today the family comprises about 70 described species worldwide, placed in the four genera Sisyra , Sisyrina Banks, 1939, Sisyborina Montserrat, 1982 (Sisyrinae), and Climacia McLachlan, 1869 (Climamciinae) (Cover & Resh, ; Monserrat, ; Perkovsky & Makarkin, ). Seven extant species occur in Europa, five in Germany (Hölzel & Weißmair, ; Saure, ; Weißmair, , ), and three in Thuringia (Bellstedt & Brettfeld, ; Gruppe, ).…”

The morphology of mature larvae of Sisyra nigra was studied and documented with a broad spectrum of techniques. Special emphasis is on the cephalic anatomy and on the digestive tract. Cephalic structures are highly modified, with numerous autapomorphic conditions, including a globular head capsule, an extended area with large cornea lenses, a massive tentorium, a strongly developed prepharyngeal pumping apparatus with a horizontal arrangement of dilators, a sharp bend between the prepharynx and pharynx, and an unusual filter apparatus at the entrance of the large crop. The thoracic and abdominal muscle sets, and the legs are largely unmodified. Postcephalic apomorphies are conspicuous tergal setiferous tubercles, trifid setiferous pleural projections, single pretarsal claws, zigzag-shaped abdominal tracheal gills, and a dense vestiture of setae on the terminal abdominal segments. Mandibulo-maxillary stylets curved outwards are an unusual apomorphy also found in the semiaquatic larvae of Osmylidae. Semiaquatic or aquatic habits and secondarily multisegmented antennae are potential synapomorphies of these two groups and Nevrorthidae (Osmyloidea). A sistergroup relationship between Sisyridae and Nevrorthidae suggests that fully aquatic habits of larvae may be a synapomorphy of both families. A specialized terminal antennal seta is a potential groundplan apomorphy of Neuroptera, with secondary loss in Nevrorthidae and Ithonidae + Myrmeleontiformia, respectively. A trumpet-shaped empodium is likely an apomorphy of Neuroptera excluding Coniopterygidae and Osmyloidea, and the secondary loss an apomorphy of Ithonidae on one hand, and Myrmeleontiformia excl. Psychopsidae on the other. K E Y W O R D S larval anatomy, phylogeny, sponges, Spongillaflies

“…The Megaloptera is a small holometabolous taxon with an estimated World fauna of 348 extant species (modified from Cover & Resh 2008). It generally receives ordinal status and has been clearly placed within the Neuropterida (Kristensen 1981(Kristensen , 1991Whiting et al 1997;Aspöck et al 2001).…”

Phylogenetic review of dobsonflies of the subfamily Corydalinae and the genus Corydalus Latreille (Megaloptera: Corydalidae)

Phylogenetic relationships of the World genera of dobsonflies, subfamily Corydalinae, are reappraised, as well as those of species of the New World genus Corydalus, both on the basis of morphological characters. Previous phylogenetic hypotheses of dobsonfly genera by Glorioso, Penny, and Contreras-Ramos, respectively, are re-evaluated, and a fourth revised phylogeny is presented. Ninety-five characters of 10 taxa, one outgroup and nine ingroup taxa, were used in the updated analysis of Corydalinae. It recognizes four lineages, with Chloroniella as sister to the other three, of which the Nevromus lineage (Acanthacorydalis + Nevromus + Neoneuromus) is sister to the Corydalus lineage (Chloronia + Platyneuromus + Corydalus), and both as a group are sister to the Protohermes lineage (Protohermes + Neurhermes). The main changes in the updated Corydalinae phylogeny are the placement of Chloroniella as sister to all other dobsonfly genera, and the placement of Acanthacorydalis as a member of the Nevromus lineage. Previously, Penny had proposed Chloroniella as sister to all dobsonfly genera except the Protohermes lineage, and both Glorioso and Penny, respectively, placed Acanthacorydalis as sister to the Corydalus lineage. About Corydalus, its species phylogeny is herein updated, as four species from Venezuela were added to the genus after its taxonomic revision. For the new phylogeny, 120 characters of 35 taxa, two outgroup and 33 ingroup taxa, were used. It produced a strict consensus of two trees, better resolved than the previous one. The C. arpi species group is moved to sister of all other species except the C. cephalotes species pair, while the C. batesii species group is conserved, being the only unresolved group within the phylogeny. Two of the species added, C. hayashii and C. mayri, belong to the well defined C. arpi species group, of Guayana Shield affinity, whereas C. crossi is sister to a large and widespread group beginning with the C. nubilus species group, and C. clavijoi is sister to C. tesselatus within the latter group.

“…Two families of Megaloptera were recorded from the Nee Soon freshwater swamp forest. The Megaloptera are also known as the dobsonflies, and are famous for the enormous mandibles which adult males from some genera possess (Cover & Resh, 2008). However, in most species, the adult form does not feed at all, and it is theorised that the mandibles are a secondary sexual characteristic, meant to attract mates or drive off rivals (Cover & Resh, 2008).…”

The Nee Soon freshwater swamp forest is a vital area for biodiversity conservation in Singapore. A survey of the aquatic macroinvertebrates in the streams of the Nee Soon drainage was carried out to capture a representative sample of the communities present. Here, we present the different groups of macroinvertebrates sampled as well as their abundance and distribution within the freshwater swamp forest. An annotated checklist of the orders of the macroinvertebrates found in the freshwater swamp forest follows, together with information on their distribution and abundance within the Nee Soon catchment.
