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.

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.

This study reviews the taxonomy of cestodes of the genus Catenotaenia Janicki, 1904 (Cyclophyllidea: Catenotaeniidae) in Eurasia and presents the first molecular phylogenetic hypothesis of Catenotaenia, Skrjabinotaenia Ahumyan, 1946 and Meggittina Lynsdale, 1953, all parasites of rodents. The phylogenetic data are based on sequences of 28S ribosomal RNA. The analysis does not support the proposed subfamilial classification of the Catenotaeniidae into Catenotaeniinae Spasskii, 1949 and Skrjabinotaeniinae Genov & Tenora, 1979. Instead, the main division appears to be between Eurasian species and a basal Nearctic species. The results support the monophyly of the Skrjabinotaeniinae but not that of the Catenotaeniinae or Catenotaenia as traditionally understood. It is suggested that the Old World catenotaeniid cestodes appeared in murid rodents and diverged subsequently as Skrjabinotaenia and Meggittina (Skrjabinotaeniinae) in Africa. According to the molecular phylogeny, Eurasian Catenotaenia codiverged with their hosts, with the exception of Catenotaenia dendritica that originated via a host shift from murid rodents to squirrels. The crown clade of Eurasian Catenotaenia consists only of species found in cricetid rodents and the three terminal species only in the Arvicolinae (voles). Phylogenetic structure within the Eurasian Catenotaenia clade suggests seven distinct lineages, three of which are described as new: C. apodemi n. sp. from Apodemus peninsulae (type host) from the Republic of Buryatia and from Apodemus uralensis from the Lower Tunguska River, North-Central Siberia (Russian Federation); C. cricetuli n. sp. from Cricetulus barabensis from the Republic of Buryatia and C. microti n. sp. from Microtus socialis from Kazakhstan. A new genus (Catenotaenioides n. g.) is proposed for C. kirgizica Tokobaev, 1959, a basal species within the Old World clade. Of the various morphological features, proglottid form (short acraspedote proglottids widest at middle vs. elongated craspedote proglottids widest posteriorly) is consistent with the phylogenetic pattern exhibited by catenotaeniid cestodes.

A systematic review of the tribe Hyaliodini from Australia and New Caledonia is given. Four new genera and 13 new species of Hyaliodini described: Bolbomiris gen. n. (B. cola sp. n., B. samuelsoni sp. n.), Epelisentis gen. n. (E. celiae sp. n., E. gressitti sp. n.), Plikomiris gen. n. (P. freycinetiaphilus sp. n., P. monteithi sp. n.) and Torunotum gen. n. (T. badius sp. n., T. hystrix sp. n., T. oviformis sp. n., T. pindaii sp. n. and T. psydrax sp. n.), as well as Femurocoris madeleinensis sp. n., Montagneria yahouensis sp. n. Femurocoris Carvalho and Montagneria Akingbohungbe and their type species are redescribed, as is M. cuneatus (Distant). Stethoconus praefectus (Distant) is reported from Australia for the first time. A dichotomous key, illustrations of male genitalia, scanning electron micrographs and habitus photographs are provided. A phylogenetic analysis of a morphological dataset was undertaken resulting in a monophyletic Hyaliodini, and the New Caledonian hyaliodines form a subclade. A discussion of the infra-subfamilial classification of the Deraeocorinae is given.

Descriptions are given of the anatomy of the pericarp in representatives of 28 genera of the Simaroubaceae sensu lato, including Stylobasium, as well as the ontogeny of the endocarp in 9 of them. There is marked heterogeneity in the family in both pericarp structure and endocarp ontogeny. Eight different endocarp types are recognised, the distribution of which shows considerable correlation with the subfamilial classification of Engler. This study provides further evidence that the family in the broad sense is an artificial assemblage. Endocarp structure provides support for the inclusion of both Recchia and Stylobasium in the Surianoideae. Guilfoylia has no recognisable endocarp; the occurrence of periclinal divisions within the inner protoderm of young pericarps suggests that this is a derived condition. The inclusion of Allantospermum and Nothospondias within the Irvingioideae and Simarouboideae respectively is not supported by their pericarp structures.

We have investigated the spectrograms (dispersion: 8Å/mm) in the photographic infrared region fromλ7500 toλ9000 of some carbon stars obtained by the coudé spectrograph of the 74-inch reflector attached to the Okayama Astrophysical Observatory. The names of the stars investigated are listed in Table 1.
