    Recently, a new species of Austropotamobius was described in Europe. How could this species have remained hidden for such a long time, in a high research-activity area like Europe?

    The highly divergent populations of the new crayfish species found in the Apuseni Mountains, Romania, were estimated to have split 15 million years ago from the Dinarides and evolved in isolation due to the tectonic north-eastern movement of the Tisza-Dacia mega-unit (including the Apuseni Mountains) through the Pannonian Basin during the Miocene (Pârvulescu et al., 2019). Supported by morphological evidence, these populations

    were described as a new species of crayfish, named Austropotamobius bihariensis, after the region of Biharia where the species is endemic. The diagnostic morphological features are the lack of denticulation on the lower edge of the antennal scale, a significantly shorter bell-shaped rostrum, and fewer tubercles on the palms of the chelae than its relatives (Pârvulescu, 2019).

    Historically, the populations of A. bihariensis were ascribed as A. torrentium, with no consideration that they might be different subspecies based on morphology (e.g., Băcescu, 1967, Holdich et al., 2006). These populations

    Dear IAA members

    I hope that all of you are enjoying the Summer season. I have two nice news items for you:

    Crayfish symposium in Hong Kong

    In May 2019, I organized a crayfish symposium entitled “Biology of Freshwater Crayfish” at the mid-year meeting of The Crustacean Society in Hong Kong. Several IAA members participated and lectured as invited speakers: Antonín Kouba (University of

    South Bohemia, Czech Republic) provided us with an update on the recent situation with alien crayfish species in Europe, Jason Coughran (Sheridan College, Australia) presented on the historic cultural value of the Japanese endangered freshwater crayfish Cambaroides japonicus, and Jiri Patoka (Czech University of Life Sciences Prague, Czech Republic) gave a talk on the current status of crayfish in Indonesia. Also, Denis Audo (China), Kento Kawata (Japan), Fang Li (China), Darren C.K. Yeo (Singapore), Ingo S. Wehrtmann (Costa Rica) provided interesting presentations on paleontology, immunology and conservation of freshwater crayfish. I would of course recommend them to become IAA members and attend the upcoming IAA meeting.

    One of the Chinese attendees informed me that the pet trade market in China is growing and that marble crayfish or marmorkrebs (Procambarus virginalis) are sold on the online market. China has a unique ecosystem and is home to valuable native freshwater crayfishes - Cambaroides schrenckii and C.

    dauricus. Chinese astacologists should beware of the illegal release of alien crayfish and pay attention to conservation of their native crayfish species.

    In the last slot of the symposium, member of the organizing committee of IAA23 Antonín Kouba, introduced the upcoming international IAA meeting in the Czech Republic. He presented the venue and invited the people present to attend the meeting. He did an excellent presentation, and several attendees of the symposium showed interest in IAA23.

    Invitation for IAA23

    Pavel Kozák launched the IAA23 website and the meeting announcement is now available on the IAA website. Our next IAA biannual symposium will be held in the Czech Republic from 29 June - 3 July 2020. I am really looking forward to meeting new IAA members and to seeing old crayfish friends again.

    In the Czech Republic, we will decide on the next IAA symposium location. If you are interested to organize IAA24 in 2022, please feel free to e-mail me. Since no IAA meetings have been hosted in the southern hemisphere after 2006, I would particularly be happy to receive proposals from this region. As an international society, it is important that our biannual meetings cover both the northern and southern hemisphere.

    A regional European IAA meeting will take place, August 27-30

    2019, within the walls of medieval town Visby on Gotland, the

    largest island in the Baltic Sea. Apart from usual crayfish topics

    like crayfish plague, conservation, genetics, physiology,

    management and invasives, there will be a special theme with

    aquaculture in general and crayfish culture in particular. Subjects

    like epigenetics and risk analyses will most likely also be touched

    upon.

    The meeting will start on August 27 with a day dealing with local

    and regional crayfish and aquaculture questions (in Swedish). In

    the evening there is a welcome reception for everyone, local

    regional and international alike. Then follow two days of plenary

    talks, contributed talks, posters and workshops. The last day,

    August 30, will be devoted to an excursion on Gotland visiting

    sites for noble crayfish farming, for extermination of the invasive

    signal crayfish and for restoration of noble crayfish populations.

    The day will end with a tour of the research station Ar on the

    northern part of Gotland where we will also have the conference

    banquet in the form of a traditional Swedish crayfish party. The

    meeting is organised by Swedish University of Agricultural

    Sciences, Blue Centre Gotland, Eastern Finland University, and

    Gotland County Administrative Board. Every crayscientist,

    crayexpert, crayenthusiast or any other type of a crayperson -

    meaning farmer, manager, scientist or interested - is warmly

    invited to take part.

    Dear astacologists

    On behalf of the official organizing committee, the International Association of

    Astacology, and the hosting institution, the Faculty of Fisheries and

    Protection of Waters, University of South Bohemia, as well as the

    Organizing and Scientific committee, I would hereby like to cordially

    invite you to the IAA 23 Symposium, which will be held in the

    beautiful South Bohemia Region of the Czech Republic from

    June 29 to July 3, 2020.

    The Symposium will be held in the charming Hotel Štekl,

    located in close proximity to the enchanting Hluboká nad

    Vltavou Château, from where you will be able to

    appreciate the local atmosphere.

    This event will be focused on any crayfish-related topic

    including species diversity and distribution, conservation,

    physiology, genetics, ecology, ethology, diseases, fishery

    and aquaculture.

    We promise not only a high quality scientific program

    with several keynote speakers, but also a carefully

    are in the north-eastern limit of A. torrentium range and thus have been overlooked in large scale phylogeographic studies. The earliest records in Romania mention A. torrentium only in the south-west of the country (Scriban, 1908; Entz, 1912; Călinescu, 1929). International literature does not mention these crayfish populations until 2013, and they are recorded as A. torrentium in the latest comprehensive paper describing the distribution of crayfish in Europe of Kouba et al. (2014). Based on the similar rationales, there may be even more cryptic species of Austropotamobius in Dinarides (Klobučar et al., 2013).

    Anne Schrimpf and Ioana-Diana Popovici are acknowledged for providing the first molecular sequences of this species, and Andrei Acs for the valuable help in the field. Last but not least, Mael Glon is acknowledged for reviewing the manuscript.

    In April 2019 I was contacted by a customs officer from a country in East Asia and asked to help identify specimens in a shipment of imported freshwater crayfish. Obtaining information from this country is difficult, so this apparent case of a ‘mislabeled’ ship-ment is shareworthy.

    According to the customs officer the crayfish originated from a producer in Western Australia, a third party shipped the crayfish from Perth (presumably a legal export), the shipment was la-beled as Cherax cainii and the stated purpose of the shipment was for human consumption/eating.

    However, on inspection of the shipment, the customs officer suspected there were in fact two species of crayfish included in the shipment (Figures 1 and 2), and correctly identified one spe-cies as Cherax cainii (Austin) (Figure 1) but suspected the other

    species (Figure 2) might have been Euastacus sulcatus Riek, or juvenile C. cainii. I was able to establish the specimen in Figure 2 was not any spe-cies of Euastacus, or C. cainii, but looked rather more like Cherax destructor Clark, and advised accordingly. The customs officer indicated that this type of ‘mislabeling‘ inci-dent was common (along with other types of paperwork irregu-larities) and evidently in this case, customs were fully aware the crayfish were not destined for consumption, but most likely for a different type of trade. The customs officer said they would be following-up on the matter with the importer.

    So, it turns out that Big Brother is watching, and in this case he (or she, Big Sister?) had some pretty good eyes, and appears capable of detecting cases like this among presumably high vol-umes of freight: these are good things to discover. Not quite as encouraging was learning from the customs officer that various types of paperwork irregularities (e.g. mislabeling incidents) like this happen all the time, and are evidently not all accidental.

    Further evaluation of this phenomenon was not possible as addi-tional data could not be located regarding the country con-cerned.

    Imagine the surprise of Bowling Green Municipal Utilities (BGMU) employee James Dillon, when he happened to glance into the intake filter at their Chestnut Street water treatment facility. The Barren River runs directly through Bowling Green and is the source for local drinking water after being pro-cessed by BGMU. The first part of that process involves pumping water, and some debris, through a course filter system where most large particles are trapped against a traveling screen. Then, on regular intervals, a jet of water flushes the filtered material back to the river. Serendipitously, James happened to be looking in the filter between jets of water and saw what he was certain was a lobster! And he wasn’t far off. It was an enormous bottlebrush crayfish, Barbicambarus cornutus. He brought it to the Biology Department at Western Kentucky University where Dr. Steve Huskey identified and preserved it.

    B. cornutus is endemic to the upper Green River basin in south-central Ken-tucky and north-central Tennessee and is recognized as one of the largest cray-fishes in North America. The species inhabits small to medium-sized rivers and is known to associate with large rubble and boulders. This specimen measures 151 mm total length, 83 mm carapace length, and has a wet weight of 149.5g. Discussions with Chris Taylor at the Illinois Natural History Survey revealed this specimen is 6 mm larger than any B. cornutus in their collection and will soon take up residence as the largest bottlebrush crayfish on the INHS shelves.

    Author Jean-François Parpet (J-FP) has visited the Musée des Confluences (previously Natural History Museum of Lyon or MHNL) on 16 January 2019 and has accessed its collections at the Con-servation Centre and Collections studies (Centre de Conservation et d’études des Collections, CCEC, 13A rue Bancel, 69007, Lyon, France). One antique jar was stored in the Conservation Centre (Figures. 1 and 2), containing four crayfish speci-mens - two females and two males - and labeled with information written in French as follows:

    This information can be translated in Eng-lish like this: “Crustaceans from Japan, Donation from Mr. Villard, 1889 (Museum of Lyon)”. He has considered that they could be specimens of the only one en-demic crayfish species in Japan, but want-ed to be sure so he asked for help.

    One of authors, Tadashi Kawai (TK), con-firmed that the crayfish belongs to the

    genus Cambaroides, since the specimens have the unique characteristics of Cam-baroides: juvenile suture on the male first pleopod (Fig. 3A) and the shallow sinus of the annulus ventralis of the female (Fig. 3B). Also, TK identified the Japanese cray-fish Cambaroides japonicus shows a sub-cylindrical carapace, flattened chelae, and the apical robe of the male’s first pleopod is cornified and swollen laterally (Kawai and Fitzpatrick, 2004). The speci-mens in the Conservation Centre and Collections studies, fully matched with the morphology of the type specimens (Figures 2 and 3).

    It is remarkable that the antique speci-mens of C. japonicus were transported from Japan to France at least 130 years ago. Author Cédric Audibert (CA), curator of the Sciences of Life collections, has conducted investigations in an attempt to identify the donor, Villard, in the records of the Museum.

    In the 19th century only one Villard was known in the Lyon region as a potential donor and associated to natural history: Louis Villard (Figure 4), a silk manufactur-er and entomologist. In the registry of the MHNL, Louis Villard (1837-1915) is asso-ciated with donations between 1876 and 1889. About his first donation the 3rd of April 1876, it is written, translated in Eng-

    lish: “Mr. Villard, velvet manufacturer, 33 Royal Street, Lyon”. After verification, this hypothesis seemed to be the good one because at that time, there was a velvet manufacturer at this address in Lyon. He is known as someone interested in Cole-optera. His name is common in natural history bulletins where he tries to contact Russian entomologists and is known to exchange naturalized animals for beetles. Between 1876 and 1889 in MHNL, for example, he has exchanged or given two specimens of two different bird species and one young crocodile for 18 exotic specimens of beetles. It is important to notice that at this time velvet manufac-turers had a privileged relationship with Asia, because that is where they got their silk. Villard donated animals four times, essentially specimens of different bird species. However, his last donation in 1889 were precisely the four C. japonicus specimens, possibly obtained in exchange for some of his beetles.

    These specimens may have been trans-mitted to him in another way than through his relationships with Asia. Actu-ally, the current descendants of Villard's family found in his personal belongings an old Japanese newspaper, the Yorozu

    Chōhō (万朝報), dated Wednesday,

    March 14, 1894. This newspaper, pub-

    lished between 1892 and 1940, is written in old Japanese lan-guage. The title can be translated as “various morning infor-mation”, a daily newspaper aiming at a very large popular audi-ence (Seiichi et al., 1995). The copy found in Louis Villard belong-ings contains a letter dated March 9, 1894, written in French by Charles Fine, a member of Villard's wife's family. The newspaper preserved by Villard suggests the two men knew each other very well. Charles Fine was an explorer and, in this letter, he describes his 25 000 km journey around the world and his mid-course stop in Yokohama (a traditional port in central Honshu Island, near Tokyo, Japan) where he met traders.

    Of course, these facts occurred five years after the deposit of the specimens at the MHNL, but this does not exclude that Charles already had long-standing links with Japan.

    The mystery remains intact 130 years later, but the specimens are nonetheless real and visible in the CCEC of the Musée des Confluences, Lyon, France.
