This paper is the conclusion of the “Spaghetti Project” aiming to revise French species of Terebellidae sensu lato (s.l.) belonging to the five families: Polycirridae, Telothelepodidae, Terebellidae sensu stricto (s.s.), Thelepodidae and Trichobranchidae. During this project, 41 species were observed, 31 of them new for science: eight species of Polycirridae, eleven species of Terebellidae s.s., three species of Thelepodidae and nine species of Trichobranchidae. We provide a comprehensive key for all European species of terebellids with a focus on the important diagnostic characters for each family. Finally, we discuss issues on taxonomy, biodiversity and cryptic and pseudo-cryptic species of polychaetes in European waters, based on results obtained during this project.

Under global warming scenarios, rising temperatures can constitute heat stress to which species may respond differentially. Within a described species, knowledge on cryptic diversity is of further relevance, as different lineages/cryptic species may respond differentially to environmental change. The Brachionus calyciflorus species complex (Rotifera), which was recently described using integrative taxonomy, is an essential component of aquatic ecosystems. Here, we tested the hypothesis that these (formerly cryptic) species differ in their heat tolerance. We assigned 47 clones with nuclear ITS1 (nuITS1) and mitochondrial COI (mtCOI) markers to evolutionary lineages, now named B. calyciflorus sensu stricto (s.s.) and B. fernandoi . We selected 15 representative clones and assessed their heat tolerance as a bi-dimensional phenotypic trait affected by both the intensity and duration of heat stress. We found two distinct groups, with B. calyciflorus s.s. clones having higher heat tolerance than the novel species B. fernandoi . This apparent temperature specialization among former cryptic species underscores the necessity of a sound species delimitation and assignment, when organismal responses to environmental changes are investigated.

In the tenthredinid hymenopteran genus Empria, the European species with a paired whitish patch on tergum 1 are considered tentatively as a species-group termed the E. hungarica group. The type materials of Empria pumila (Konow), E. pumiloides Lindqvist and E. tricornis Lindqvist were examined. The lectotype and paralectotypes of E. pumila are designated, and new diagnostic characters for E. pumila and E. pumiloides are given. A key for the Northern European species of the E. hungarica group is compiled. The results of a comparison of the phenology and some metrical characters of the adults of E. pumila and E. pumiloides are presented in the form of diagrams. E. pumiloides is recorded for the first time from Russia and Germany. The records of E. hungarica from Estonia (Saaremaa) are reported as the northernmost for that species. All available distributional records of Empria hungarica in the Palaearctic are given in the text, and those localized reliably are also mapped.

Abstract The taxonomy of Aspergillus species has recently been revolutionized with the introduction of cryptic species and section concepts. However, their species-level identification in routine laboratories remains a challenge. The aim of this study was to prospectively assess the identification accuracy of cryptic species of Aspergillus in various laboratories using the mass spectrometry identification (MSI) platform, an independent and freely accessible online mass spectrometry database. Over a 12-month period, when a select set of MSI users identified cryptic species, they were contacted and requested to send the isolates to our laboratory for sequence-based identification. Sequence and MSI identification results were then compared. During the study period, 5108 Aspergillus isolates were identified using MSI including 1477 (28.9%) cryptic species. A total of 245 isolates that corresponded to 56 cryptic species and 13 sections were randomly selected for DNA sequencing confirmation. Agreement between the two methods was 99.6% at the section level and 66.1% at the species level. However, almost all discrepancies (72/83, 86.7%) were misidentifications between closely related cryptic species belonging to the same section. Fifty-one isolates from noncryptic species were also identified, thus yielding 100% and 92.2% agreement at the section and species level, respectively. Although the MSI fungus database is a reliable tool to identify Aspergillus at the section level, the database still requires adjustment to correctly identify rare or cryptic species at the species level. Nevertheless, the application properly differentiated between cryptic and sensu stricto species in the same section, thus alerting on possible specific isolate characteristics.

A revision of the Australian taxa of the genus Spergularia (Caryophyllaceae) on the basis of herbarium material, field studies and analysis of morphological characters necessitates realignment of some taxa and application of some neglected names, clarifying circumscription and understanding of the species of this genus. Eleven species are here recognised, with five considered indigenous, Spergularia nesophila and S. diandroides described as new and S. tasmanica transferred to Spergularia from Lepigonum. Fruits and seeds provide compelling diagnostic characters in this genus and are used in supplementary dichotomous and tabular diagnostic keys. Scanning electron micrographs (SEMs) illustrate key seed shape and surface features.

AbstractA revision of the European species of Siphona Meigen (1803) is presented. New diagnostic characters, especially based on structural differences in the male and female genitalia, are introduced. Also the traditionally used characters are revised. Four species are described as new: ingerae, mesnili and variutu from Denmark, and martini from Sweden. Thirteen other species are diagnosed. All seventeen species are keyed, and details of the genitalia are illustrated. Two lectotypes are designated. Notes on the affinities and distribution of the species are given. The biology is reviewed and possible host-parasite relationships are presented in an annotated list. True aerial swarming (synorchesia) of male Tachinidae is reported for the first time.

Johnson, P. tridentatae sp. n. from Genista tridentata L., P. deschkanus sp. n. from Genista cinerea (Vill.) DC., P. andalusicus sp. n. probably from Retama sphaerocarpa (L.) Boiss., P. echinosparti sp. n. from Echinospartum lusitanicum (L.) Rothm., P. baetica sp. n. from Genista versicolor Boiss., P. vueltas sp. n. from Genista florida L. and G. cinerea (Vill.) DC., P. scorpius sp. n. from Genista scorpius (L.) DC., P. pumila sp. n. from Genista versicolor subsp. pumila (Hervier) Fern. Casas, P. eugregori sp. n. from Cytisus austriacus L. and C. ratisbonensis Schaeff., and P. etnensis sp. n. from Genista aetnensis (Biv.) DC. Phyllonorycter purgantella (Chrétien, 1915) is recognized as bona species. Phyllonorycter dalmatinella (Amsel, 1951) and P. picardi Buvat, 1995 are junior subjective synonyms of Phyllonorycter lapadiella (Krone, 1909). The lectotype of Phyllonorycter haasi (Rebel, 1901) is designated. The species are divided into three species groups, Phyllonorycter cerasinella (Reutti, 1853) standing apart from these groups. New country records of several species are given.

Botrytis cinerea has been reported as a species complex containing two cryptic species, groups I (Botrytis pseudocinerea) and II (B. cinerea sensu stricto). In order to compare the pathogenicity of group I and group II of B. cinerea, we have selected 4 strains of group I and 4 strains of group II. The results demonstrated that competitive infection of group II was more on grape, cucumber and paprika leaves, than group I. However the results on bean leaves did not correlate the applied B. cinerea group.

This study provides an updated checklist and an illustrated guide to the 17 currently known stygobiont Malacostraca species of the state of Yucatan (Yucatan Peninsula, Mexico). The compilation is based on the individuals collected during our cave-diving expeditions (2016–2019), and, has the purpose of expanding previous knowledge on the taxonomy of these subterranean crustaceans. The identification guide contains drawings of the main diagnostic characters of the species as well as a brief introduction of the relevant malacostracan orders. The information is further complemented with a historic account and timeline of the stygobiont Malacostraca species of the Yucatan Peninsula. This is the first study that provides a unified tool for the morphological identification of these highly endemic species.

Endogeophilus ichnusae gen. et sp. nov. (Chilopoda: Geophilidae sensu stricto) is described based on three specimens from two localities in south-western Sardinia, examined by light and scanning electron microscopy. The new centipede resembles the rare Ibero-Pyrenean genus Galliophilus Ribaut & Brolemann, 1927 in some features, especially in the forcipular segment, and the temperate European species Geophilus electricus (Linnaeus, 1758) in other features, especially in the ultimate leg-bearing segment. However, the true affinities of E. ichnusae gen. et sp. nov. are uncertain, because the new species departs significantly from the majority of geophilids for the higher number of legs (91–107 pairs in the specimens examined), the slender trunk segments (the sternites being longer than wide), the relatively stout legs (the tarsus being only about twice as long as wide) and the very short setae (≤ 15 mm) scattered on the body surface. All these features are probably derived and suggest adaptation to a more strictly endogeic habit than other geophilids.
