The chrome azurol-S test, which is a chemical spot-test for Al accumulation in wood, was applied to 443 wood samples of members of the Rubiaceae. A positive reaction was found in 103 specimens. Comparison of the results with earlier analyses of leaves of Rubiaceae shows that Al accumulation occurs more frequently in leaves than in wood. The strongest Al accumulators occur in the neotropical genera Psychotria subg. Heteropsychotria, Coussarea, Faramea, and Rudgea. The distribution of Al accumulators is discussed in view of recent tribal and subfamilial classification of the Rubiaceae. The major conclusion is that Al accumulation is almost limited to the subfamily Rubioideae. Within the Rubioideae, however, not all tribes show the character, especially the predominantly herbaceous Anthospermeae, Paederieae, Rubieae, and Spermacoceae. Al accumulation in the Urophylleae, Pauridiantheae, Craterispermeae, and Knoxieae supports earlier associations of these tribes with the Rubioideae.

AbstractBased on external and internal structural features of larvae and adults, the phylogeny of Trictenotomidae, Salpingidae, Pythidae, Boridae, Tydessa Peacock (included previously in Pilipalpinae), Pilipalpinae, Pyrochroinae, and Pedilinae is reconstructed as: (Trictenotomidae + Salpingidae + Pythidae) + (Boridae + {Tydessa + [Pilipalpinae + (Pyrochroinae + Pedilinae)]}). The genus Tydessa is placed in its own monobasic subfamily, Tydessinae. Both Tydessinae and Pilipalpinae are included in Pyrochroidae, along with Pyrochroinae, Pedilinae, and possibly Cononotus and Agnathus. A historical account of the classification of Pilipalpinae is presented, along with a revised subfamilial classification of Pyrochroidae and Pythidae.

Subfamilial Classification

The morphology of the trinucleid exoskeleton is reassessed and various new structures and terms defined. On the basis of new interpretations of cephalic morphology, particularly that of the fringe, of all known genera, a new subfamilial classification is proposed. Two new genera, Deanaspis and Whittardolithus , and the subfamily Reedolithinae are proposed, and the genus Botrioides Stetson resurrected. The existing subfamilies, Trinucleinae, Gryptolithinae and Marrolithinae are recast considerably and the Tretaspidinae, Novaspidinae and Incaiinae rejected. The Hanchungolithinae is left unmodified. Evolution within the family is discussed together with the distribution of genera in terms of recent palaeogeographic reconstructions. A review of the relations between phylogeny and ontogeny confirms the essentially recapitulative nature of trinucleid ontogenies. A list of current generic assignments of known species is given

Subfamilial Classification

A growth series of Stringocephalus gubiensis, described here, reveals that the cardinal process of Stringocephalus originated from a bilobate structure, and the growth of its dorsal median septum is highly related to cardinal process development. From this observation we conclude that Kaplex is, structurally and temporally, a suitable ancestor for Stringocephalus, with Bornhardtina ancestral to Kaplex. Subfamilial classification of the family Stringocephalidae is revised based on the presence or absence of median septa and the nature of hinge plates as well as on cardinal process formation. The Kaplexinae and Omoloninae are proposed as new subfamilies, with the Kaplexinae, including Kaplex and Erectocephalus, and the Omoloninae, including Omolonia, Kumbella, and Hemistringocephalus. Morphologic study of South China and Western Canadian Stringocephalus reveals that late forms of the genus tend to have a higher dorsal septum and more complex cardinal process than the early forms. In view of functional morphology, these trends reflect functional perfection of the cardinal process build-up and the lever system for improving the efficiency of opening and closing the shell.

Subfamilial Classification

A worldwide checklist is provided for the family Endomychidae (Coleoptera: Cucujoidea). An updated subfamilial classification is presented, based on recent higher-level phylogenetic analyses and incorporating many recently described taxa. At present, Endomychidae contains 1782 valid species and subspecies in 130 genera organized into 12 subfamilies. Two new synonyms are recognized: Symbiotes latus Redtenbacher, 1849 = Symbiotes latus var. roberti Falcoz & Roman, 1930 syn. nov.; and Cholovocerida Belon, 1884 = Displotera Reitter, 1887b syn. nov. Two new combinations are proposed: Cholovocerida ecitonis (Wasmann, 1890) for Coluocera ecitonis Wasmann, 1890 comb. nov.; and Cholovocerida maderae (Wollaston, 1854) for Cholovocera maderae Wollaston, 1854 comb. nov. Loeblia ceylanica Dajoz, 1972a is here designated as the type species for Loeblia Dajoz, 1972a, and Rhymbus hemisphaericus Gerstaecker, 1858 is designated as the type species for Rhymbus Gerstaecker, 1858. Nomen nudum status is proposed for Mycetaea tafilaletica Smirnoff, 1957. Thirty-two species originally described under Corynomalus Chevrolat, 1836 and subsequently transferred to Amphix Laporte, 1840, have been returned to Corynomalus. Known fossil taxa are summarized.

Subfamilial Classification

Plant genomes consist, to a considerable extent, of non-coding repetitive DNA. Several studies showed that phylogenetic signals can be extracted from such repeatome data by using among-species dissimilarities from the RepeatExplorer2 pipeline as distance measures. Here, we advanced this approach by adjusting the read input for comparative clustering indirectly proportional to genome size and by summarizing all clusters into a main distance matrix subjected to Neighbor Joining algorithms and Principal Coordinate Analyses. Thus, our multivariate statistical method works as a “repeatomic fingerprint,” and we proved its power and limitations by exemplarily applying it to the family Rosaceae at intrafamilial and, in the genera Fragaria and Rosa, at the intrageneric level. Since both taxa are prone to hybridization events, we wanted to show whether repeatome data are suitable to unravel the origin of natural and synthetic hybrids. In addition, we compared the results based on complete repeatomes with those from ribosomal DNA clusters only, because they represent one of the most widely used barcoding markers. Our results demonstrated that repeatome data contained a clear phylogenetic signal supporting the current subfamilial classification within Rosaceae. Accordingly, the well-accepted major evolutionary lineages within Fragaria were distinguished, and hybrids showed intermediate positions between parental species in data sets retrieved from both complete repeatomes and rDNA clusters. Within the taxonomically more complicated and particularly frequently hybridizing genus Rosa, we detected rather weak phylogenetic signals but surprisingly found a geographic pattern at a population scale. In sum, our method revealed promising results at larger taxonomic scales as well as within taxa with manageable levels of reticulation, but success remained rather taxon specific. Since repeatomes can be technically easy and comparably inexpensively retrieved even from samples of rather poor DNA quality, our phylogenomic method serves as a valuable alternative when high-quality genomes are unavailable, for example, in the case of old museum specimens.
