Anatomical characters and systematics ofAnodontites trapesialis(Lamarck, 1819) from South America (Mollusca, Bivalvia, Unionoida, Muteloidea)

: The genus Duchesnea includes two species originally from India: D. indica and D. chrysantha. In Northwestern Argentina the monitoring of wild strawberry-like species was carried out; during 2002- 2016, many populations of D. indica and none of D. chrysantha were discovered. Red- and white-fruited plants of D. indica were collected from disturbed areas and ex situ conserved in green-house and in nursery conditions. Were also consulted materials from different national and international herbaria, and we only found reports of D. indica with red fruit for Argentina. In the present work, we report for the first time the presence of D. indica f. albocaput in Argentina and South America, cohabiting with populations of D. indica f. indica in the underwoods of Tucumán. This finding broadens the distribution range of D. indica f. albocaput, cited as endemic to Japan by Naruhashi 1992. The morphological and anatomical characters of the two botanical forms of D. indica (red fruit genotypes and white fruit genotypes) are also presented: fruit color, number of leaflets, and crystal form

Anatomical Characters

Abstract. Conifers are common in the Early Cretaceous Crato flora. Sterile foliage shoots of several morphotypes occur. Good preservation of several of these specimens allows detailed morphological and anatomical studies. Based on these characters, two taxa of Cheirolepidiaceae, Tomaxellia biforme and Frenelopsis sp., are identified. The palaeogeographic distribution of the genus Tomaxellia currently extends from southern South America northwards to the palaeoequatorial region. The morphological and anatomical characters of both taxa might be interpreted as adaptations to a warm and temporarily dry palaeoclimate, however their habitat can not be reconstructed yet, due to scarcity of the remains. Koniferen stellen eine wesentliche Komponente der unterkretazischen Crato-Flora dar. Es kommen sterile beblätterte Zweige verschiedener Morphotypen vor. Die gute Erhaltung einiger dieser Fossilreste lässt detaillierte morphologisch-anatomische Untersuchungen zu. Auf der Basis solcher Merkmale wurden zwei Taxa der Cheirolepidiaceae, Tomaxellia biforme und Frenelopsis sp., identifiziert. Das Areal der Gattung Tomaxellia wird damit vom südlichen Südamerika nordwärts, in die paläoäquatoriale Region erweitert. Morphologische und anatomische Merkmale beider Taxa können als Anpassungserscheinungen an ein warmes und periodisch trockenes Paläoklima interpretiert werden. Auf Grund des seltenen Vorkommens solcher Fossilreste können noch keine Angaben zu ihrem ehemaligen Habitat gemacht werden. doi:10.1002/mmng.200600009

A new monotypic genus Argosadalia gen. nov. and new species A. priscilla sp. nov. are described from the forests of Bolivia, Ecuador, and Peru. The new taxon is placed in the tribe Coccinellini in a group informally designated as the “Neda-group,” and comprising the genera Neda Mulsant; Mononeda Crotch; Neoharmonia Crotch and Argosadalia. Key morphological and anatomical characters of the new taxa are described and illustrated and the character states that define the Neda-group are reviewed.

AbstractThe Eleticinae are an archaic and in many respects primitive group of Meloidae found in South America (widespread), Africa (south of the Sahara Desert), and the Oriental Region (India to Thailand). They are, in general, poorly represented in collections, and very little is known definitely of their bionomics. On the basis of an analysis of adult anatomical characters the subfamily is defined in detail and is classified to the generic level in the present paper. Two tribes, seven subtribes, and 10 genera are recognized, keyed, and diagnosed. The tribe Spasticini is arranged as follows: Protomeloina Abdullah, transferred from the Meloinae and reduced to subtribal rank, with Protomeloe Abdullah; Spasticina Kaszab with Spastica Lacordaire; Xenospastina, new subtribe, with Xenospasta, new genus; and Anthicoxenina, new subtribe, with Anthicoxenus Fairmaire and Germain, formerly placed in the Anthicidae, and Iselma Haag-Rutenberg. The arrangement of the tribe Eleticini is: Eospastina, new subtribe, with Eospasta, new genus, and Serrospasta, new genus; Eleticina Wellman with Eletica Lacordaire (and including, as subgenera, Sibuteletica Pic, Meteletica Kaszab, and Proeletica Kaszab); and Ertlianina, new name for Ertliini Kaszab, with Ertliana Selander (= Steniselma Borchmann, new synonymy) and Ceriselma Borchmann, the latter elevated from subgeneric rank in Iselma. Species described as new are Protomeloe simplex (Argentina), Spastica minas (Brazil), Xenospasta flava (Colombia), and Serrospasta vittata (Colombia).

AbstractEumitrioid Usnea species are characterized by a tubular central axis throughout the entire thallus. Four species were identified in South America: Usnea baileyi is a (sub-) tropical species occurring both in continental South America and the Galapagos; U. perplectata has a scattered distribution worldwide and occurs in continental South America, mainly on the eastern range; U. flaveola and the newly described species U. subflaveola are both so far endemic to the Neotropical Andes. Distinct chemotypes, as well as anatomical characters, such as the thickness ratio of the medulla or the presence of medullar pigmentation, are diagnostic in delimiting these species. A detailed description of the species is provided together with an identification key.
