FLORAE MALESIANAE PRAECURSORES XLVII. CENSUS OF MALESIAN CASTANOPSIS (FAGACEAE)

This paper deals with the names and typication of the 34 species recognized in Malesia. Specimens important for the knowledge of the distribution of each species have been cited with their locality. Indexes to names and to all examined specimens are given. Ten new species are described: Castanopsis clemensii, densinervia, endertii, microphylla,, oligoneura, oviformis, paucispina, peduneulata, psilophylla, all from Borneo, and johorensis from Malaya. C. hypophoenieea and C. lucida are new combinations based on Quercus hypophoenieea v. Seem, and Alseodaphne lucida Nees in Wall, respectively. Castanopsis ebneri and woodii are reduced to evansii, hullettii to lucida, pachycarpa to rhamnifolia, conspersispina, to tungurrut, dispersispina to hypophoenieea, ridleyi partly to tungurrut and partly to megacarpa, kinabaluensis to foxworthyi, pearsonii to mottleyana, junghuhnii and schlenkerae to acuniinatissima. Castanopsis selangorensis A. Cam. is regarded as a doubtful species. The number of endemic species is for Malaya 5, Borneo 11, the Philippines 1; the total number of species, is for Sumatra 11, Malaya 17, Java 4, Borneo 20, the Philippines 4, Celebes 2, the Moluccas 1, New Guinea 1, the Lesser Sunda Islands none

Tree Resin Composition, Collection Behavior and Selective Filters Shape Chemical Profiles of Tropical Bees (Apidae: Meliponini)

The diversity of species is striking, but can be far exceeded by the chemical diversity of compounds collected, produced or used by them. Here, we relate the specificity of plant-consumer interactions to chemical diversity applying a comparative network analysis to both levels. Chemical diversity was explored for interactions between tropical stingless bees and plant resins, which bees collect for nest construction and to deter predators and microbes. Resins also function as an environmental source for terpenes that serve as appeasement allomones and protection against predators when accumulated on the bees' body surfaces. To unravel the origin of the bees' complex chemical profiles, we investigated resin collection and the processing of resin-derived terpenes. We therefore analyzed chemical networks of tree resins, foraging networks of resin collecting bees, and their acquired chemical networks. We revealed that 113 terpenes in nests of six bee species and 83 on their body surfaces comprised a subset of the 1,117 compounds found in resins from seven tree species. Sesquiterpenes were the most variable class of terpenes. Albeit widely present in tree resins, they were only found on the body surface of some species, but entirely lacking in others. Moreover, whereas the nest profile of Tetragonula melanocephala contained sesquiterpenes, its surface profile did not. Stingless bees showed a generalized collecting behavior among resin sources, and only a hitherto undescribed species-specific “filtering” of resin-derived terpenes can explain the variation in chemical profiles of nests and body surfaces from different species. The tight relationship between bees and tree resins of a large variety of species elucidates why the bees' surfaces contain a much higher chemodiversity than other hymenopterans
