This short account is an invited contribution to the Zootaxa special volume ‘Twenty years of Zootaxa.’ Zootaxa was first published on 28 May 2001. Between this date and December 2020, 116 papers were published in Zootaxa that mention Bryozoa, comprising mostly descriptions of new species and higher taxa, but also including molecular sequencing (e.g. Fehlauer-Ale et al. 2011; Taylor et al. 2011; Franjevic et al. 2015), invasive-species research (e.g. Ryland et al. 2014; Vieira et al. 2014), checklists (e.g. Vieira et al. 2008), classification (e.g. Bock & Gordon 2013), bryozoans as associates of other organisms (e.g. Rudman 2007; Chatterjee & Dovgal 2020; Chatterjee et al. 2020), metazoan phylogeny (e.g. Giribet et al. 2013), biographies of historical figures who worked on bryozoans (e.g. Calder & Brinkmann-Voss 2011; Calder 2015) and a catalogue of the fossil invertebrate taxa described by William Gabb (including 67 bryozoan species) (Groves & Squires 2018). Of the 116 papers, 15 (13%) were open-access.

Policies to promote urban forest diversity were assessed in 49 California, U.S. municipalities through a short questionnaire, followed by evaluation of street tree inventories and approved planting lists. While the majority of respondents (82%) indicated maintaining species diversity was an objective in managing their municipal forest, fewer than half of those responding positively (48%) had codified the objective in an actual urban forest management plan. Protecting against invasive species was an objective for a minority of communities (24%). Street tree inventories, provided by 18 respondents, indicated a high existing diversity within the communities of the state of California (avg. 185 species per community; range 95–408). In communities where both inventories and approved planting lists could be compared directly, the number of approved species for future planting was 29% of the number of species in the existing inventory. This suggests that the future diversity of California’s urban forests may be at risk. In order to improve diversity of their municipal forests, it is suggested communities retain an experimental approach to evaluating new species, build productive collaborations with all stakeholders as well as other communities, and develop outreach opportunities to enhance public awareness of the multiple values of a diverse urban forest.

In the course of his excavations in the Upper Eocene beds of the Fayûm during the early part of 1902, Mr. H. J. L. Beadnell unearthed a remarkably fine shell of a very large species of Testudo. A brief description of this specimen was afterwards published in Cairo by the present writer, and it was made the type of a new species, Testudo Ammon. At the same time Mr. Beadnell gave a short account of the beds in which it was found, and of the methods employed by him for its preservation and transport to the Museum in Cairo.

Summary Sheathoid nematodes of the genus Hemicriconemoides are migratory root-ectoparasites of many crops but damage is documented for only a few species. Hemicriconemoides paracamelliae sp. n., isolated in Hangzhou, Zhejiang, China, from the rhizosphere of Cinninghamia lanceolata, is described together with H. kanayaensis and H. parataiwanensis. These three species are characterised morphologically and molecularly with important morphological details elucidated by SEM photographs. The new species can be characterised by the en face view having a dorsoventrally orientated oral disc with slit-like opening, and the labial plate being composed of two lateral semi-globular shaped projections on the lateral sides of the oral disc. This new species has the first lip annulus expanded and slightly wider than the second, stylet 83 (80-85) μm long, excretory pore located 5-6 annuli posterior to the base of the pharyngeal bulb, vulva slit-like, vulval flaps absent, spermatheca rounded to oblong-shaped, and anus located 5-8 annuli posterior to vulva. The tail is elongated, conoid, with the terminal annuli curving dorsally or ventrally to form a finely rounded tip. The study provides the first record of H. kanayaensis from mainland China, a new host association of H. parataiwanensis, and molecular sequencing data of the 18S, 28S D2-D3 and ITS sequences.

As primary or obligate sessile organisms, bryozoans depend upon a substratum resource that affects their abundance, distribution and diversity. These animals can colonize virtually any type of substratum, including other organisms and artificial structures. Associations between bryozoans and sponges are commonly reported in the literature, but there are few studies discussing the association between these two taxa in detail. Here we present data on the bryozoan community found on shallow-water sponges from Bahia coast, northeastern Brazil, including their taxonomic status, colony form and adaptative structures utilized by these bryozoans to grow on sponges. Twenty-one bryozoan species were found attached to the surface of sixteen species of sponges. Five new species of cheilostome bryozoans are described. A total of 105 colonies were studied and most of them are erect delicate branching (44 colonies) and encrusting patches (34 colonies). The majority of bryozoan colonies were attached to the surface of rugose-textured sponges (67 colonies; 61%). This suggests that bryozoans are more likely to settle on irregular and rough surfaces. Patches colonies were mainly attached to the portion of the sponge that was in contact with the seabed, and spot colonies were particularly found in spatial refuges, showing the preference of larvae to settle on shaded and less exposed substrata. Most erect bryozoans were attached to the lateral sponge surface, other colonies grew on the underside and few on the upper surface of the sponges. These colonies were attached either using anchoring rhizoids, rigid bases, or stolons. The bryozoan species and genera reported here are common in northeastern Brazil and considered generalists in terms of larval settlement requirements. The bryozoan-sponge association studied is considered a non-obligatory commensalism (inquilinism).

It is often assumed that, if a few species are introduced into a relatively empty environment, the subsequent diversification will take the form of a logistic growth curve, rising to an equilibrium level of species richness. The diversifications of taxa in higher categories commonly resemble logistic curves, although there are no well-defined theoretical bases for such a resemblance.A model of diversification of taxa in higher categories is based on the notion that many taxa originate rapidly. Relatively small changes leading to new species occur at a high frequency, while larger changes leading to progressively higher taxa occur with progressive rarity. During diversification in an empty environment, few large changes will occur before the environment is filled. The rate of filling, relative to the rate of production of higher taxa, determines the richness of taxa in higher categories and gives the diversification curves a logistic appearance although the maximum level achieved is not an equilibrium. Subsequently, opportunities for diversification will generally lead only to the appearance of taxa in progressively lower categories.

There has been no previous report detailing the taxonomy of marine bryozoans along the coasts of Vietnam. Here we report on the taxonomy and diversity of bryozoans collected among drift coral cobbles from a beach in the tropical Co To archipelago, Gulf of Tonkin, northern Vietnam. We detected 27 bryozoan species (23 cheilostomes, four cyclostomes) in a coelobite assemblage inhabiting crevices in the cobbles, and holes made by boring molluscs. The degree of bryozoan preservation varied greatly, suggesting that the cobbles had accumulated on the beach over a period of months to years, or even decades. Coral reefs in the Co To archipelago underwent a catastrophic decline in 2003–2008, and it is unclear whether the bryozoan assemblage reflects past diversity, present diversity remaining in the coral rubble, or both. We describe six new species: Parasmittina acondylata n. sp., Metroperiella cotoensis n. sp., Microporella tonkinensis n. sp., Rhynchozoon setiavicularium n. sp., R. latiavicularium n. sp., and Disporella phaohoa n. sp. All but two of the previously described species were already known from the Central Indo-Pacific coastal biogeographical realm of Spalding et al. (2007), which includes Vietnam. We report the third Recent record of the thalamoporellid Dibunostoma reversum (Harmer, 1926), which is quite similar to and might be conspecific with the lower Miocene species Thalamoporella transversa Guha & Krishna, 2004; while it is premature to synonymize the two, we transfer T. transversa to Dibunostoma, as D. transversum. The calcareous, sheet-like, encrusting foraminiferan Planorbulina larvata was prominent in the coelobite assemblage and was often observed in substrate competition with bryozoans. A limited analysis of competitive interactions indicated that the encrusting bryozoans in the coelobite assemblage encountered P. larvata more often than they encountered other bryozoans, and that P. larvata out-competed bryozoans for substrate, reinforcing a growing sense of the importance of encrusting foraminifera in tropical and subtropical hard-substrate communities.

Of the 10 species of freshwater bryozoans previously reported from Australia, only Fredericella australiensis, Hyalinella lendenfeldi and Lophopodella carteri can be positively confirmed from existing preserved material. From a survey of all known museum collections of freshwater bryozoans comes compelling evidence that a specimen labelled ‘Plumatella toanensis’ is actually Hyalinella lendenfeldi, including the only known statoblasts of this species. Plumatella agilis is recognised tentatively pending new material. Fredericella sultana, Plumatella emarginata and P. repens are not represented by any known specimens, although they are likely to occur in Australia. Hyalinella punctata and Gelatinella toanensis have been previously reported in error. Two other previously misidentified specimens, including Hyalinella vaihiriae, are now reported as new species: Plumatella velata and P. rieki. A taxonomic key is given for Australian freshwater bryozoan species, including species both verified from Australia and others only presumed to occur there.

In this study we describe Rhyacophila siparantum sp. nov., a new species of the Rhyacophila philopotamoides species group from the Bjeshkët e Nemuna Mountains in Kosovo, based on morphological (male adults) and molecular (sequencing of the barcode region of the cytochrome c oxidase subunit I gene (COI)) characteristics. The new species is morphologically closest to Rhyacophila schmidinarica Urbanič, Krušnik & Malicky, 2000, and also closely resembling Rhyacophila hirticornis McLachlan, 1879. R. siparantum sp. nov. differs from both its most similar congeners primarily by the shape of the segment X, which is in lateral view short apically and with a pronounced lateral hump on the posterior edge. This difference, combined with other characters related to the shape of the second segment of inferior appendages, spine pattern of parameres and size of ventral teeth on segments VI and VII, make R. siparantum sp. nov. easily distinguishable from both most similar congeners. Phylogenetic and taxonomic relationships were reconstructed using two methods of phylogenetic inference, and two species delimitation methods. All this supports Rhyacophila siparantum sp. nov. as a distinct taxon. The adults of Rhyacophila siparantum sp. nov. were found during the period May – August, nearby a small rheocrene spring inside a forested area. The new species is most probably a microendemic of the Bjeshkët e Nemuna, a mountainous massive known for several other endemic species of caddisflies. Rhyacophila siparantum sp. nov. is the seventeenth known species of the genus Rhyacophila Pictet, 1834 from Kosovo.
