It is the third of six volumes which - view the Hypotricha, one of the three major taxa of the spirotrichs. The first volume is about the Oxytrichidae, a rather large group, many species of which have 18 highly characteristically arranged frontal-ventral-transverse cirri and, much more importantly, a comparatively complex dorsal ciliature due to (oxytrichid) fragmen- tion of dorsal kineties during cell division (Berger 1999). The second volume deals with the Urostyloidea, which are characterised by a zigzag-arrangement of the ventral cirri (Berger 2006). Although this pattern is often very impressive, it is a relatively simple feature originating by a more or less distinct increase of the number of frontal-ventral-transverse cirri anlagen. These anlagen produce cirral pairs which are serially arranged in non-dividing specimens. Some - ers are likely astonished that the monograph on urostyloids does not include Urol- tus, a group of tailed species, which also have a distinct zigzagging cirral pattern. However, morphological and molecular data indicate that the zigzag pattern of U- leptus evolved independently, that is, convergently to that of the urostyloids. Thus, Uroleptus was excluded from the urostyloid review. A zigzag pattern is also known from some oxytrichids, for example, Neokeronopsis, Territricha, Pattersoniella, showing that this pattern evolved several times independently (Berger 1999, 2006, Foissner et al. 2004).\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Helmut Berger\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1402089163\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781402089169\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/20\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 737\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.70lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 1.56d","brand":"Helmut Berger","offers":[{"title":"Hardcover","offer_id":47424317980927,"sku":"9781402089169","price":329.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_cc92c740-10be-48b4-b6b1-02d47f3aa44a.jpg?v=1761529537","url":"https:\/\/www.whiterainbookhouse.com\/products\/monograph-of-the-amphisiellidae-and-helmut-berger-9781402089169","provider":"WR Book House","version":"1.0","type":"link"}
