Chemical signals yield critical socio-ecological information in many animals, such as species, identity, social status or sex, but have been poorly investigated in birds. Recent results showed that chemical signals are used to recognize their nest and partner by some petrel seabirds whose olfactory anatomy is well developed and which possess a life-history propitious to olfactory-mediated behaviours. Here, we investigate whether blue petrels ( Halobaena caerulea ) produce some chemical labels potentially involved in kin recognition and inbreeding avoidance. To overcome methodological constraints of chemical analysis and field behavioural experiments, we used an indirect behavioural approach, based on mice olfactory abilities in discriminating odours. We showed that mice (i) can detect odour differences between individual petrels, (ii) perceive a high odour similarity between a chick and its parents, and (iii) perceive this similarity only before fledging but not during the nestling developmental stage. Our results confirm the existence of an individual olfactory signature in blue petrels and show for the first time, to our knowledge, that birds may exhibit an olfactory kin label, which may have strong implications for inbreeding avoidance.

A revision of the subfamily Microscaphidiinae Looss, 1900 is presented and characters of taxonomic significance discussed. The genus Microscaphidium Looss, 1900, contains M. reticulare (van Beneden, 1859) Looss, 1901 (synonyms M. japonicum Oguro, 1941; M. caballeroi Groschaft, 1977); M. aberrans Looss, 1902 (synonym M. reticulare in part); and M, warui, sp. nov. Confusion in the literature over the identities of M. reticulare and M. aberrans is discussed. A neotype is selected for the former species and a lectotype for the latter. Polyangium linguatula (Looss, 1899) Looss, 1902 (synonyms P. miyajimai Kobayashi, 1921; P. colymbi Poche, 1925; P. longiseminale Chattopadhyaya, 1972) is the sole species in Polyangium Looss, 1902. The genus Angiodictyum Looss, 1902 contains A. parallelum (Looss, 1901) Looss, 1902; A. posterovitellatum Chattopadhyaya, 1972; A. longum, sp, nov.; A. glossoides, sp. nov. Polygorgyra, gen. nov., is proposed for P. cholados, sp. nov. Microscaphidium chelonei Chattopadhyaya, 1972 nec Mehrotra, 1973 and Angiodictyum anteroporum Chattopadhyaya, 1972 are regarded as species inquirendae. Microscaphidium chelonei Mehrotra, 1973 nec Chattopadhyaya, 1972 is a nomen nudum. The following species are recorded for the first time from the green turtle, Chelonia mydas (L.) in Australian waters: Microscaphidium reticulare; M. aberrans; M. warui; Angiodictyum posterovitellatum; A. longum; Polygorgyra cholados.

Speleomantes are the only plethodontid salamanders present in Europe. Multiple studies have been performed to investigate the trophic niche of the eight Speleomantes species, but none of these studies included hybrid populations. For the first time, we studied the trophic niche of five Speleomantes hybrid populations. Each population was surveyed twice in 2020, and stomach flushing was performed on each captured salamander; stomach flushing is a harmless technique that allows stomach contents to be inspected. We also assessed the potential divergence in size and body condition between natural and introduced hybrids, and their parental species. Previously collected data on Speleomantes were included to increase the robustness of these analyses. In only 33 out of 134 sampled hybrid Speleomantes we recognized 81 items belonging to 11 prey categories. The frequency of empty stomachs was higher in females and individuals from natural hybrid populations, whereas the largest number of prey was consumed by males. We compared the total length and body condition of 685 adult salamanders belonging to three types of hybrids and three parental (sub)species. Three group of salamanders (one hybrid and two parental species) showed significantly larger size, whereas no difference in body condition was observed. This study provided novel ecological information on Speleomantes hybrid populations. We also provided insights into the potential divergence between hybrids and parental species in terms of size and body condition. We discuss our findings, and formulate several hypotheses that should be tested in the future.

Annelid worms represent a significant part of freshwater benthic communities worldwide and Oligochaeta is a particularly species-rich group. Dero (A) bimagnasetus (Naididae) previously found and described from a small marsh in Surinam in 1974, has now been found for the first time in Barra Lake, MG, Brazil. Due to the scarce biological data and absence of ecological information in the literature regarding this species we are presenting morphological information on the specimens obtained and the physical and chemical characteristics of the habitat they were found. This species occurred only in the littoral zone of Barra Lake, in muddy, low oxygen, low conductivity and low organic matter sediment. The four individuals collected ranged 3.17-4.15 mm total length; 0.25 - 0.26 mm body width and 0.16-0.21 mm3 total volume. Considering the present anthropic pressures on freshwater biota and fast biodiversity losses worldwide it is now recognized that attention must be paid to low abundance species and the urgency for preservation of their habitats.

Tetrix gibberosa (Wang & Zheng) is a high-backed pygmy grasshopper species from eastern PR China. Due to its reduced hind wings and pleomorphism (length changes of hind wings and the hind pronotal process, which is generally called macropterous and brachypterous morphs), the species have been described into different species which involve several taxonomically confused genera. This study clarifies its taxonomy and distribution and provides ecological information for the species. At the same time, we comment the relationships of related genera in the subfamily Tetriginae, including Tetrix Latreille, Exothotettix Zheng & Jiang, Alulatettix Liang, Aalatettix Zheng & Mao, Formosatettix Tinkham, and Formosatettixoides Zheng. Additionally, we report for the first time that nematodes can parasitize pygmy grasshoppers. New synonyms are proposed: Tetrix gibberosa (Wang & Zheng, 1993) = Alulatettix bulbosus Zheng & Zhong, 2001, syn. nov., = Exothotettix jiangxiensis Liang & Jia, 2008, syn. nov., = Tetrix glochinota Zhao, Niu & Zheng, 2010, syn. nov., = Alulatettix nigromarginalis Zhang, Deng & Zha, 2014, syn. nov., = Alulatettix flavotibialis Zhang, Deng & Zha, 2014, syn. nov..

A revision of 245 Heterodermia s.lat. collections from Thailand preserved in RAMK, herb. F. Schumm and herb. K. Kalb is presented. The 39 species found in this material are assigned to the genera Heterodermia Trevis. s.str. with a lower cortex and Pachysporaria-type ascospores (without sporoblastidia), Leucodermia Kalb, gen. nov., with foliose to subfruticose, linear-elongate, ribbon-like, dichotomously branched lobes, loosely attached to the substrate, without a lower cortex, apothecia often with pruinose discs and Polyblastidium-type ascospores (with sporoblastidia) and Polyblastidium Kalb, gen. nov. distinguished by a foliose thallus attached to the substrate, no lower cortex and mostly Polyblastidium-type ascospores. The remaining species are assigned to groups without a formal generic name, awaiting further results from molecular phylogenies. The Heterodermia comosa group contains species which are similar to Leucodermia, but differ in having a subfruticose or rosulate thallus with ascending, spathulate or paddle-shaped lobes and the Heterodermia obscurata group which contains species with a fluffy cottony woolly lower surface which is totally or at least partly impregnated by anthraquinones. Standardized descriptions are provided for all the better known Heterodermia species s.str. worldwide and all other species found in the material studied or reported for Thailand in the literature, as well as species which might be expected to occur in the country. The new species, Leucodermia borphyllidiata Kalb & Meesim, similar to L. boryi, but differing in having a phyllidiate thallus is described, and the new combinations, Leucodermia appalachensis (Kurok.) Kalb, L. arsenii (Kurok.) Kalb, L. boryi (Fée) Kalb, L. ciliatomarginata (Linder) Kalb, L. circinalis (Zahlbr.) Kalb, L. fertilis (Moberg) Kalb, L. leucomelos (L.) Kalb, L. lutescens (Kurok.) Kalb, L. vulgaris (Vain.) Kalb, Polyblastidium appendiculatum (Kurok.) Kalb, P. casarettianum (A. Massal.) Kalb, P. corallophorum (Taylor) Kalb, P. dendriticum (Pers.) Kalb, P. fragilissimum (Kurok.) Kalb, P. hypocaesium (Yasuda) Kalb, P. hypoleucum (Ach.) Kalb, P. japonicum (M. Satô) Kalb, P. magellanicum (Zahlbr.) Kalb, P. microphyllum (Kurok.) Kalb, P. neglectum (Lendemer, R.C. Harris & Tripp) Kalb, comb. nov. [Mycobank MB 813853; Basionym: Heterodermia neglecta Lendemer, R.C. Harris & Tripp, The Bryologist 110(3): 490 (2007)], P. propaguliferum (Vain.) Kalb, P. queenslandicum (Elix) Kalb, P. subneglectum (Elix) Kalb and P. violostriatum (Elix) Kalb, are made. Chaudhuria Zahlbr. is a synonym of Heterodermia s.str. and Chaudhuria indica Zahlbr. is an older synonym for Heterodermia verdonii Elix, but as the name Heterodermia indica (H. Magn.) D.D. Awasthi already exists for another species, the correct name for this taxon reverts to H. verdonii. Chemical analyses revealed that Heterodermia reagens (Kurok.) Elix must be placed into synonymy with Polyblastidium propaguliferum (Vain.) Kalb. Dichotomous keys for the identification of all species are provided. Characteristic TLC profiles for selected species are presented and Rf values for the most important terpenes and pigments are given for the first time in the standard solvents A, B' and C. Photographs showing the species as well as characteristic structures in the genera and groups are also provided. A new epitype for H. comosa from Réunion is designated.

AbstractThe Ceramius maroccanus-complex is endemic to southwestern Morocco. The status of C. maroccanus (Giordani Soika 1957) and C. montanus Gusenleitner 1990 as separate species is confirmed, C. rubripes Gusenleitner 1990 stat. n. and C. gessi sp. n. are recognized as species for the first time. The four species are redescribed/described and illustrated, and their distribution and flight period are analysed. Identification keys to males and females are provided. The C. maroccanus-complex is a monophyletic group within 'Species group 7' of Richards 1962, and is probably the sister group of the C. lusitanicus-complex.

The systematics status of the spider genus Mallinella Strand, 1906 (Araneae, Zodariidae), the phylogenetic relationshipof the species within the genus and its relationships to other zodariids were investigated by means of cladistic analysis ofmorphological data. Mallinella is redefined and characterized by a single synapomorphy: the presence of posterior ventralspines situated in front of the spinnerets arranged in a single row. The genus is clearly palaeotropical, occurring in Africa,Indian subcontinent, Indo-Burma, Sundaland, Wallacea and Polynesia-Micronesia.Two hundred and two (202) Mallinella species are treated. One hundred and one (101) species are described as newand placed in twenty-two (22) species-groups, making Mallinella the largest zodariid genus. Nineteen (19) species are redescribed, the conspecific sex of seven (7) species is discovered and described for the first time. Fifteen (15) new com-binations are proposed. Nine (9) Storena species are here transferred to Mallinella: M. beauforti (Kulczyński, 1911) comb.nov., M. sciophana (Simon, 1901) comb. nov., M. sobria (Thorell, 1890) comb. nov., M. fasciata (Kulczyński, 1911)comb. nov., M. vicaria (Kulczyński, 1911) comb. nov., M. redimita (Simon, 1905) comb. nov., M. melanognatha (van Has-selt, 1882) comb. nov., M. nilgherina (Simon, 1906) comb. nov., M. vittata (Thorell, 1890) comb. nov. Two Storena spe-cies are transferred to Asceua: A. dispar (Kulczyński, 1911) comb. nov., A. quinquestrigata (Simon, 1905) comb. nov. OneStorena species is transferred to Oedignatha (Liocranidae): O. aleipata (Marples, 1955) comb. nov. One Storena speciesis transferred to Cybaeodamus: C. lentiginosus (Simon, 1905) comb. nov. Storena tricolor Simon, 1908 is transferred tothe Asteron complex of Australia. Three Storena and two Mallinella species are misplaced; they belong to undescribedgenera (S. kraepelini Simon, 1905; S. lesserti Berland, 1938; S. parvula Berland, 1938; M. khanhoa Logunov, 2010; M.rectangulata Zhang et al., 2011). Mallinella vittata (Thorell, 1890) comb. nov. is revalidated and removed from the syn-onymy with M. zebra (Thorell, 1881). Storena vittata Caporiacco, 1955 is removed from homonym replacement (S. ca-poriaccoi Brignoli, 1983) with S. vittata Thorell, 1890 (= M. vittata comb. nov.). Storena annulipes Thorell, 1892 isremoved from its preoccupied name with S. annulipes (L. Koch, 1867) in Storena and transferred to Mallinella; its re-placement name S. cinctipes Simon, 1893 is suppressed.Zodarion luzonicum Simon, 1893, Storena multiguttata Simon, 1893, S. semiflava Simon, 1893 and S. obnubila Si-mon, 1901 are regarded as nomina dubia. Six Indian species were misplaced in Storena; they belong to one of the follow-ing genera: Mallinella, Heliconilla gen. nov., Workmania gen. nov., Heradion, or Euryeidon. These taxa are S. arakuensisPatel & Reddy, 1989, S. debasrae Biswas & Biswas, 1992, S. dibangensis Biswas & Biswas, 2006, S. gujaratensis Tikader& Patel, 1975, S. indica Tikader & Patel, 1975 and S. tikaderi Patel & Reddy, 1989. They are regarded as species incertaesedis.A new genus, Heliconilla gen. nov., is proposed for nine species, six of which are new to science while the otherthree are transferred from Mallinella and Storena. These taxa are: H. irrorata (Thorell, 1887) comb. nov., H. oblonga(Zhang & Zhu, 2009) comb. nov., H. thaleri (Dankittipakul & Schwendinger, 2009) comb. nov.Workmania gen. nov. is established to accommodate two species from Southeast Asia; W. juvenca (Workman, 1896)comb. nov. is transferred from Storena.It is unlikely that the origin of Mallinella dates back more than 100 MYA. Mallinella or its ancestor is believed tohave evolved during the Cretaceous, after the separation of South America from Gondwana, and the greater part of itsevolution took place during the Tertiary. The Asian-Australian lineages of Mallinella could migrate to India via GreaterSomalia before or after the K-T extinction (65 MYA), before the Indian subcontinent joined Asia (ca. 45 MYA).The bio-geographic history of the genus involves plate tectonics during the Cretaceous and the Cenozoic in combination with cli-matic changes and alternating climatic cycles which might have led to episodes of range expansion, isolation of populations and allopatric speciation.
