New Material

During examination of new material of Burmese amber three individuals of Tarachoptera were discovered. The inclusions are sufficiently well preserved and allow identification and description of these rare, fossil insects. The species belong to the family Tarachocelidae and are described as Kinitocelis macroptera spec. nov. (†) and Retortocelis spicipalpia spec. nov. (†). The species and their preservations are described in detail, and photos and line drawings are provided for wing venation, head, mouthparts, and abdomen. The hitherto described species of Tarachoptera are summarized in a checklist.   Taxonomic acts Kinitocelis macroptera Mey & Wichard, spec. nov. – urn:lsid:zoobank.org:act:E0B1624A-C69E-4B53-851F-4368AC21C614Retortocelis spicipalpia Mey & Wichard, spec. nov. – urn:lsid:zoobank.org:act:9778E7E2-EEFE-4DC5-B891-54DF114D525C

Important Site

In Siberia, there are numerous Jurassic and Cretaceous locations abundant in fossil insects. The Teete outcrop (renamed Kempendyay) located in the eastern Siberia (Russia) is an important site due to its age estimated to beginning of the Lower Cretaceous as well as its high taxa diversity and very good specimen preservation. However, it is poor in fossils of the Limoniidae. Study of the rare Tipulomorpha material from the Teete locality (= Kempendyay) is presented herein and two new species are described and illustrated. One of them belongs to the family Pediciidae, Prearchitipula ryszardi sp. nov., and the second to the family Limoniidae, Eotipula wieslawi sp. nov. Both species are dedicated to two well-known Polish specialists of fossil Diptera Nematocera.

Abstract. Based on a total of 14 inclusions from Burmese amber the new insect order Tarachoptera is established. The family Tarachocelidae previously described from Burmese amber and then placed in Amphiesmenoptera incertae sedis is assigned to this new order. The genus Kinitocelis gen. nov. is established to accommodate three new fossil species: K. hennigi spec. nov., K. divisinotata spec. nov. and K. brevicostata spec. nov. The new genus differs from Tarachocelis gen. nov. by the absence of androconial scales on the wings and the loss of Cu2 in the forewings. The species are described in detail and the critical characters are illustrated by line drawings and photos. Both males and females were described. The species can be distinguished by traits in the wing venation. The new order Tarachoptera is placed in the superorder Amphiesmenoptera based on the presence of seven amphiesmenopteran apomorphies and nine tarachopteran apomorphies. Apomorphic characters of Trichoptera and Lepidoptera could not be disclosed, which suggests an independent origin and evolution from an amphiesmenopteran ancestor which was not the ancestor of the Trichoptera-Lepidoptera clade. The species of Tarachoptera are tiny insects with a wing span of 2.3–4.5 mm but highly specialized according to their aberrant morphology. Aspects of the presumed life history of the adults were deduced from some of the derived morphological traits that could be interpreted as adaptations to a highly structured micro-environment.

Two New Species

Stegocoleus Jarzembowski & Wang is an enigmatic genus in the family Ommatidae, known to date only from Burmese amber. This genus possesses a unique combination of characters, including antennal grooves on the ventral side of head, well-developed epipleural rims, and presence of separated procoxae, which makes its systematic position unclear. Here we report two new species of Lepidomma from mid-Cretaceous Burmese amber, L. longisquama sp. nov. and L. jarzembowskii sp. nov. Based on these well-preserved specimens and new morphological details revealed by widefield fluorescence and confocal microscopy, we discuss the morphological similarities between Lepidomma and the enigmatic Stegocoleus. We suggest that Stegocoleus is not a basal ommatid, but a highly derived form of ommatid beetles.

Two new species of the Plecoptera family Diamphipnoidae are described from Chile. Illustrations of the details of the male genitalia, female genitalia, and eggs are provided for these two new taxa. Diamphipnoa fresiae sp. nov. has the lowest latitudinal distribution of the genus in South America and the male is the smallest known for the family and has also unusual wing venation. Diamphipnopsis oncolensis sp. nov., also a small species is known only from the Parque Oncol, south of Valdivia, Chile. This species is characterized by its distinctive abdominal coloration pattern in both sexes of the adult. Additionally, the large diameter of the eggs and the prominent tubercles of the chorion characterize this new species.

Fossil Genus

Three new fossil species from Burmese amber are described, one clearly in family Calamoceratidae, the other two in the highly variable family Odontoceridae. The family Odontoceridae contains 18 disparate genera, but there are no good diagnostic characters, which makes it difficult to place fossil taxa in this family. We here offer a revised diagnosis for the family, highlighting the lack of good diagnostic characters, and the need to use sets of characters to place (extinct) taxa in this family. On this taxonomic basis we describe two new species in the hitherto monotypic fossil genus Palaeopsilotreta Wichard & Wang, 2017 (Odontoceridae), Palaeopsilotreta burmanica sp. nov. and P. cretacea sp. nov., redescribe the type species based on additional information, and describe features of the female, based on two specimens, one of which is embedded adjacent to a male identified as P. xiai. Males of Palaeopsilotreta bear bipectinate antennae; the antennae of the females are simple and filiform. Similarly, bipectinate antennae are present in the third species we describe, Bipectinata orientalis gen. et sp. nov., which otherwise lacks the character combinations associated with the Odontoceridae, but clearly can be assigned to the family Calamoceratidae.

AbstractThe genus Colonomyia Colless contains six species in the Australasian and Neotropical Regions. Several recognized synapomorphies leave no doubt that Colonomyia is a monophyletic group, with the Australasian species more closely related to one another than to the Neotropical species. On arguments derived from the wing venation, Colonomyia is hypothesized to be the sister-group of the genus Ohakunea Edwards, both together representing a lineage distinct from the family-level taxa currently recognized in the Sciaroidea. Colonomyia borea sp. n. from Costa Rica and C. rakelae sp. n. from Papua New Guinea are described. Recognition of these new species extends the distribution of the genus Colonomyia into the tropical zone and the northern hemisphere.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Two new species of South African Syllidae of the genusSyllisLamarck, 1818 are described.Syllis unzimasp. nov. is characterized by having unidentate compound chaetae with long spines on margin, a characteristic colour pattern and its reproduction by vivipary. Vivipary is not common among the polychaetes, but most representatives occur in the family Syllidae Grube, 1850 (in five otherSyllisspecies, two species ofDentatisyllisPerkins, 1981 and two species ofParexogoneMesnil & Caullery, 1818).Syllis unzimasp. nov. differs from the other viviparous species in having large broods (>44 juveniles) which develop synchronously. Development of the juveniles is similar to that of free-spawningSyllisspecies, but the appearance of the first pair of eyespots and the differentiation of the pharynx and proventricle occur later inS. unzima.Syllis amicarmillarissp. nov., is characterized by having an elongated body with relatively short, fusiform dorsal cirri and the presence of one or two pseudosimple chaeta on midbody parapodia by loss of blade and enlargement of shaft.Syllis unzimasp. nov. was found in high densities on culturedHolothuria scabraJaeger, 1833 with single specimens found on a culturedCrassostrea gigasThunberg, 1793 and on coralline algae, respectively, whileS. amicarmillariswas found mainly in sediment outside an abalone farm and less frequently on culturedHaliotis midaeLinnaeus, 1758. We discuss the possible benefits of the association withH. scabratoS. unzimasp. nov.
