Three new genera and 27 new species of gall midges are described from the Late Eocene ambers: Henria baltica sp. nov., Frirenia manca sp. nov., F. musicata sp. nov., Leptosyna samlandica sp. nov., L. fastosa sp. nov. from Baltic amber and H. xystica sp. nov., H. liquida sp. nov., Stellasegna vlaskini gen. et sp. nov., S. vaporea sp. nov., S. nexa sp. nov., Rasnitsia verticosa gen. et sp. nov., F. rohdendorfi sp. nov., F. schevchenkoi sp. nov., F. melica sp. nov., F. lukashevichae sp. nov., F. leporidis sp. nov., F. marmarygma sp. nov., F. vesana sp. nov., Vincinescia alisae gen. et sp. nov., L. margarita sp. nov., L. munifera sp. nov., L. sukachevae sp. nov., L. assa sp. nov., L. larga sp. nov., L. vegeta sp. nov., L. vaticina sp. nov., and L. shcherbakovi sp. nov. from Rovno amber. Strobliella capitata Fedotova is redescribed as Henria capitata (Fedotova, 2004) (comb. nov.). Diagnoses of Henria (= Electroxylomyia Nel et Prokop, syn. nov.), Frirenia, and Leptosyna are revised. As a result, Henria comprises 3 extant and 5 extinct (Late Eocene) species, including H. eocenica (Nel et Prokop), comb. nov. (= Electroxylomyia eocenica), Frirenia comprises 1 extant and 10 Late Eocene species, and Leptosyna comprises 3 extant and 11 Late Eocene species. The tribe Heteropezini is elevated to the supertribal rank (Heteropezidi)
and included in the subfamily Lasiopterinae. Leptosynini is treated as a separate tribe, and Lasiopterinae is considered as
part of Cecidomyiidae s. str. (i.e., excluding Lestremiidae). Keys to the tribes and genera of Heteropezidi and to species
of Henria, Stellasegna, Frirenia, and Leptosyna are provided. The gall midge faunas of the Rovno and Baltic ambers are compared. Phylogenetic relationships within the supertribe
are hypothesized. 相似文献

Coral reefs are renowned as complex ecosystems with an extremely large biodiversity. Parasite-host relationships contribute
substantially to this, but are poorly known. We describe the results of a study in which approximately 60,000 corals were
searched for parasitic Leptoconchus snails (Gastropoda: Coralliophilidae) in Indo-West Pacific waters of Egypt, the Maldives, Thailand, Palau and Indonesia.
We discovered an adaptive radiation of 14 snail species, each of which lives in species-specific association with one or more
of 24 mushroom coral species. The 14 snail species are described as new to science under the names Leptoconchus inactiniformis sp. nov., L. inalbechi sp. nov., L. incrassa sp. nov., L. incycloseris sp. nov., L. infungites sp. nov., L. ingrandifungi sp. nov., L. ingranulosa sp. nov., L. inlimax sp. nov., L. inpileus sp. nov., L. inpleuractis sp. nov., L. inscruposa sp. nov., L. inscutaria sp. nov., L. intalpina sp. nov., and L. massini sp. nov. Their separation is based on indisputable molecular differences, whereas the rudimentary shell characters or impoverished
anatomical details do not allow identification. The coral hosts also serve to distinguish the snail species, as none of the
former was found to contain more than one of the latter. The complexity of coral reefs is still underrated, as is shown here
by the application of DNA taxonomy as an indispensable approach to unravel cryptic radiations, which must be known in order
to understand the functioning of the ecosystem. 相似文献

A new subfamily of predaceous diving beetles, Liadytiscinae subfam. nov., including two genera and four species, Liadytiscus gen. nov. (L. cretaceus sp. nov., L. longitibialis sp. nov., and L. latus sp. nov.) and Liadroporus gen. nov. (L. elegans sp. nov.), from the Late Tithonian-Berriasian (Huangbanjigou, Yixian Formation) of China is described. Two new genera, Mesoderus gen. nov. with two species, M. magnus sp. nov. and M. ventralis sp. nov., and Sinoporus gen. nov. with one species, S. lineatus sp. nov., are also described; their position in the system of Dytiscidae remains uncertain. Relationships of the taxa described
with Recent and fossil taxa of the same rank and some presumable ecological features of the new taxa are discussed. 相似文献

Lobophora is a common tropical to temperate genus of brown algae found in a plethora of habitats including shallow and deep‐water coral reefs, rocky shores, mangroves, seagrass beds, and rhodoliths beds. Recent molecular studies have revealed that Lobophora species diversity has been severely underestimated. Current estimates of the species numbers range from 100 to 140 species with a suggested center of diversity in the Central Indo‐Pacific. This study used three molecular markers (cox3, rbcL, psbA), different single‐marker species delimitation methods (GMYC, ABGD, PTP), and morphological evidence to evaluate Lobophora species diversity in the Western Atlantic and the Eastern Pacific oceans. Cox3 provided the greatest number of primary species hypotheses(PSH), followed by rbcL and then psbA. GMYC species delimitation analysis was the most conservative across all three markers, followed by PTP, and then ABGD. The most informative diagnostic morphological characters were thallus thickness and number of cell layers in both the medulla and the dorsal/ventral cortices. Following a consensus approach, 14 distinct Lobophora species were identified in the Western Atlantic and five in the Eastern Pacific. Eight new species from these two oceans were herein described: L. adpressa sp. nov., L. cocoensis sp. nov., L. colombiana sp. nov., L. crispata sp. nov., L. delicata sp. nov., L. dispersa sp. nov., L. panamensis sp. nov., and L. tortugensis sp. nov. This study showed that the best approach to confidently identify Lobophora species is to analyze DNA sequences (preferably cox3 and rbcL) followed by comparative morphological and geographical assessment. 相似文献

Phylogenetic analyses of rbcL gene sequences and of concatenated rbcL, psbA, and nuclear SSU rRNA gene sequences resolved the generitype of Lithothamnion, L. muelleri, in a clade with three other southern Australian species, L. kraftii sp. nov., L. saundersii sp. nov., and L. woelkerlingii sp. nov. Cold water boreal species currently classified in Lithothamnion and whose type specimens have been sequenced are transferred to Boreolithothamnion gen. nov., with B. glaciale comb. nov. as the generitype. The other species are B. giganteum comb. nov., B. phymatodeum comb. nov., and B. sonderi comb. nov., whose type specimens are newly sequenced, and B. lemoineae comb. nov., B. soriferum comb. nov., and B. tophiforme comb. nov., whose type specimens were already sequenced. Based on rbcL sequences from the type specimens of Lithothamnion crispatum, L. indicum, and L. superpositum, each is recognized as a distinct species and transferred to the recently described Roseolithon as R. crispatum comb. nov., R. indicum comb. nov., and R. superpositum com. nov., respectively. To correctly assign species to these three genera based only on morpho-anatomy, specimens must have multiporate conceptacles and some epithallial cells with flared walls. The discussion provides examples demonstrating that only with phylogenetic analyses of DNA sequences can the evolution of morpho-anatomical characters of non-geniculate corallines be understood and applied at the correct taxonomic rank. Finally, phylogenetic analyses of DNA sequences support recognition of the Hapalidiales as a distinct order characterized by having multiporate tetra/bisporangial conceptacles, and not as a suborder of Corallinales whose tetra/bisporangial conceptacles are uniporate. 相似文献

Distributed in tropical and warm-temperate waters worldwide, Lobophora species are found across the Greater Caribbean (i.e., Caribbean sensu stricto, Gulf of Mexico, Florida, the Bahamas, and Bermuda). We presently discuss the diversity, ecology, biogeography, and evolution of the Greater Caribbean Lobophora species based on previous studies and an extensive number of samples collected across the eastern, southern, and to a lesser extent western Caribbean. A total of 18 Lobophora species are now documented from the Greater Caribbean, of which five are newly described (L. agardhii sp. nov., L. dickiei sp. nov., L. lamourouxii sp. nov., L. richardii sp. nov., and L. setchellii sp. nov.). Within the Greater Caribbean, the eastern Caribbean and the Central Province are the most diverse ecoregion and province (16 spp.), respectively. Observed distribution patterns indicate that Lobophora species from the Greater Caribbean have climate affinities (i.e., warm-temperate vs. tropical affinities). In total, 11 Lobophora species exclusively occur in the Greater Caribbean; six are present in the western Atlantic; two in the Indo-Pacific; and one in the eastern Pacific. Biogeographic analyses support that no speciation occurred across the Isthmus of Panama, and that the Greater Caribbean acted as a recipient region for species from the Indo-Pacific and as a region of diversification as well as a donor region to the North-eastern Atlantic. The Greater Caribbean is not an evolutionary dead end for Lobophora, but instead generates and exports diversity. Present results illustrate how sampling based on DNA identification is reshaping biogeographic patterns, as we know them. 相似文献

of the locality Obeshchayushchiy, Magadan Region, Russian Far East. The subfamily is highly diverse morphologically and combines
characters of the Labeninae and Pimplinae. It includes 11 new species described in five new genera: Labenopimpla rasnitsyni gen. et sp. nov., L. kasparyani sp. nov., Armanopimpla zherikhini gen. et sp. nov, Ramulimonstrum intermedium gen. et sp. nov., Rugopimpla vulgaris gen. et sp. nov., R. fallax sp. nov., R. angusticella sp. nov., R. macra sp. nov., R. matrona sp. nov., Micropimpla lucida gen. et sp. nov., and M. obscura sp. nov. Also described is a new monotypic genus, Tryphopimpla xoridoptera gen. et sp. nov., which combines characters of the Tryphoninae, Pimplinae, and Xoridinae and cannot be currently placed into
any of the known subfamilies. The population of fossil ichneumon wasps at this locality is distinctly dominated by females. 相似文献

Abstract: In the early Late Devonian, terminal Frasnian proetid trilobites have previously only been known from Europe and North Africa. For the first time, a rich fauna of late Frasnian proetids is described from the Virgin Hills Formation, Canning Basin, Western Australia. Seventeen species in six genera are described, of which three are new: Rudybole gen. nov., Palpebralina gen. nov. and Canningbole gen. nov. A new subgenus, Chlupaciparia (Australoparia) subgen. nov. is also described. Fourteen of the species are new: Palpebralia initialis sp. nov., P. pustulata sp. nov., ?P. sp. nov. A, Rudybole depressa sp. nov., Palpebralina pseudopalpebralis sp. nov. (comprising the subspecies P. pseudopalpebralis pseudopalpebralis subsp. nov. and P. pseudopalpebralis ultima subsp. nov.), P. minor sp. nov., P. ocellifer sp. nov., Canningbole latimargo sp. nov., C. henwoodorum sp. nov., C. macromma sp. nov., Pteroparia extrema sp. nov., Chlupaciparia (Chlupaciparia) planiops sp. nov., Chlupaciparia (Australoparia) australis sp. nov. and C. (Australoparia) lata sp. nov. The subspecies Rudybole adorfensis angusta subsp. nov. is also described. The proetids range through conodont Zones 11–13b and terminate at the Upper Kellwasser Event, which marks the terminal Frasnian mass extinction event. Three of the six proetid lineages, Palpebralia, Canningbole and Pteroparia, show evolutionary trends of eye reduction. Two of the remaining lineages, Rudybole and Palpebralina, consist exclusively of blind taxa. The last, Chlupaciparia, also comprises forms with reduced eyes. The proetids show a stepped pattern of extinction during the late Frasnian, which correlate with two Kellwasser biocrises documented in European/North African Frasnian sections. The highest diversity preceded the Lower Kellwasser event that occurred at the end of conodont Zone 12 and saw the extinction of all species present in that zone. However, only one genus, Pteroparia, locally became extinct. A major higher‐level taxonomic mass extinction at the top of Zone 13b initiated the Upper Kellwasser extinction event. This included extinction at the generic level, with all five remaining genera becoming extinct, and at the family level, with the loss of the Tropidocoryphidae. 相似文献
