Five years ago, the Panamanian evolutionary lineage (EL) C12 was uncovered along with four other ELs in an integrative phylogenetic investigation of worldwide Carychiidae. Since EL C12 lacked shell material post-molecular analysis to serve as a museum voucher, it remained undescribed. Now, after recent collection efforts of C12 and the congener, Carychium zarzaae Jochum & Weigand, 2017 at their original Panamanian sites, C12 is morphologically described and formally assigned the name, Carychium panamaense Jochum, sp. n. In sync with recent taxonomic treatment of the genus, computed tomography (CT) is used in this work to differentiate shells of C. panamaense sp. n. from geographically-proximal, Caribbean, North and Central American congeners. Recent material of topotypic Carychium jardineanum (Chitty, 1853) and undamaged C. zarzaae were additionally CT-scanned and assessed in the comparative analyses. New taxon: Carychium panamaense n. sp. 12 pp., 6 figs, gr. 8 [16.5 x 24 cm].

The present study aims to clarify the confused taxonomy of Z. schaufussi von Frauenfeld, 1862 and Zospeum suarezi Gittenberger, 1980. Revision of Iberian Zospeum micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian Zospeum species, Z. schaufussi von Frauenfeld, 1862. In this paper, we clarify its taxonomic status by designating a lectotype from the original syntype series and by describing its internal and external shell morphology. Using SEM-EDX, we attempt to identify the area of the type locality cave more precisely than "a cave in Spain". The shell described and illustrated by Gittenberger (1980) as Z. schaufussi appears not to be conspecific with the lectotype shell, and is considered a separate species, Z. gittenbergeri Jochum, Prieto & De Winter, sp. n. Zospeum suarezi was described from various caves in NW Spain. Study of the type material reveals that these shells are not homogenous in shell morphology. The holotype shell of Z. suarezi is imaged here for the first time. The paratype shell, illustrated by Gittenberger (1980) from a distant, second cave, is described as Zospeum praetermissum Jochum, Prieto & De Winter, sp. n. The shell selected here as lectotype of Z. schaufussi, was also considered a paratype of Z. suarezi by Gittenberger (1980). Since this specimen is morphologically very similar to topotypic shells of Z. suarezi, the latter species is considered a junior synonym of Z. schaufussi (syn. n.). The internal shell morphology of all these taxa is described and illustrated using X-ray Micro Computer Tomography (Micro-CT). New taxon: Zospeum gittenbergeri n. sp., Zospeum praetermissum n. sp. pp. 65-86, 15 figs, gr. 8.

Three new species of the genus Carychium O.F. Müller, 1773, Carychium hardiei Jochum & Weigand, sp. n., Carychium belizeense Jochum & Weigand, sp. n. and Carychium zarzaae Jochum & Weigand, sp. n. are described from the Southeastern United States, Belize and Panama, respectively. In two consecutive molecular phylogenetic studies of worldwide members of Carychiidae, the North and Central American morphospecies Carychium mexicanum Pilsbry, 1891 and Carychium costaricanum E. von Martens, 1898 were found to consist of several evolutionary lineages. Although the related lineages were found to be molecularly distinct from the two nominal species, the consequential morphological and taxonomic assessment of these lineages is still lacking. In the present paper, the shells of these uncovered Carychium lineages are assessed by comparing them with those of related species, using computer tomography for the first time for this genus. The interior diagnostic characters are emphasized, such as columellar configuration in conjunction with the columellar lamella and their relationship in context of the entire shell. These taxa are morphologically described and formally assigned their own names. 31 pp., 15 figs, gr. 8.

Gebundener Originalpappband. Condizione: Gut. 310 S. : Ill. ; 26 cm, 1050 g. Neuwertig erhalten. -- Inhalt: Thomas Heinzeller: Vorwort -- Bernhard Ruthensteiner: Bericht über die in der Münchener Zoologischen Staatssammlung aufgefundenen Seeigel aus dem Museum Kleinianum -- Jacob Theodor Klein und Thomas Heinzeller: Faksimile Naturalis Dispositio Echinodermatum und Übersetzung -- Armin Geus: Natürliche Ordnung und Artenvielfalt im Werk des Naturforschers Jacob Theodor Klein (1685-1759) -- Das Entstehen des vorliegenden Bandes ist dem Glücksfall zu verdanken, als längst verloren geglaubte Exemplare aus dem Museum Kleinianum in den Beständen der Münchener Zoologischen Staatssammlung wieder aufgefunden wurden. Die ausführlich beschriebenen und auf sechsunddreißig hervorragend ausgeführten Kupfertafeln abgebildeten Seeigel - rezente wie fossile Arten - klassifizierte J. T. Klein nach seinem künstlichen System, das er auf das gesamte Tierreich ausdehnte. Besonders erwähnenswert ist die damals noch umstrittene klare Unterscheidung von Belemniten und den Stacheln der Griffel-Seeigel. -- Die Basilisken-Presse ist ein Fachverlag für Wissenschaftsgeschichte und insbesondere Biologiegeschichte. Namensgeber ist der mythologische Basilisk. Der Verlag wurde 1976 in Marburg von Armin Geus, Professor für Medizingeschichte, gegründet und gab zunächst Faksimiledrucke schwer zugänglicher und wenig bekannter Schriften in kleinen und nummerierten Ausgaben heraus. Es folgten Kataloge moderner Kunst und Lyrik. Zwischen 2007 und 2022 war Basilisken-Presse als Imprint dem Verlag Natur + Text in Brandenburg mit Sitz in Rangsdorf bei Berlin angegliedert. Das Verlagsprogramm umfasst Schriften zur Biologiegeschichte sowie Biographien bedeutender Biologen, der Geistes- und Wissenschaftsgeschichte sowie zeitkritische Essays und Herausgaben zu aktuellen politischen Debatten.
