The new species, Haplopappus alpinus of section Tonestus, is formally described and illustrated. It is endemic to the high mountains of central Nevada. Vegetative and floral morphology of related species is detailed. The new species appears to be most closely related to H. eximius but also demonstrates close affinity to H. aberrans (all three are diploids with n = 9).  相似文献

It is distinguished from these species by its possession of a combination of characters including perennial, multicipital habit, lobed basal leaves, and small, pale blue flowers.  相似文献

Of all of the chrysomelid subfamilies, only the larvae of the Megascelinae, along with those of the Aulacoscelinae remain undescribed. The first instar larva of Megascelis puella Lacordaire from Panama is described, as well as the eggs. Larval characters, eggs and oviposition behaviour are used to relate the Megascelinae with the Eumolpinae in support of what is known to date concerning adult morphology.  相似文献

In this paper three species of terrestrial isopods from Sicily are discussed. Spelaeoniscus coiffaiti and Cylisticus convexus are new to the Sicilian fauna. Sicilian specimens of Spelaeoniscus coiffaiti are examined and illustrated, and the biogeographical significance of this species in Sicily is discussed. Trichoniscus panormidensis is described as a new species, and the affinities are treated.  相似文献
