A new subpecies, Tulipa cinnabarina subsp. toprakii subsp. nov. (Liliaceae) from Turkey is described. Diagnostic characters, descriptions, detailed illustrations, geographical distribution, conservation status and ecological observations on the new taxon are provided. It is also compared with the closely related Tulipa cinnabarina subsp. cinnabarina.

Tetrasticta gnatha sp. n., collected under the bark of a rotten fallen tree in Peninsular Malaysia, is described. A habitus photograph, line drawings of diagnostic characters, and a diagnosis are provided. The new species is readily distinguished from all known congeners by having long mandibles, and long, curved maxillary palpi.

The major diagnostic characters and qualitative chemical and physical tests responsible for the pharmacognostic identity of the leaf and of root of Polyscias fruticosa (L) Harms have been reported. Literature survey showed the absence of any systematic pharmacognostic studies for this plant.

In 2003, an Asian bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), the banded elm bark beetle, was detected for the first time in North America. This paper modifies the Wood (1982) key to the species of Scolytus Geoffroy to enable identification of Scolytus schevyrewi in North and Central America. Variation of diagnostic characters in Scolytus schevyrewi is disc...

A new Australian genus of Cyrtoscydmini, Scydmepitoxis gen. n. with a single species S. paradoxa sp. n. is described from New South Wales. A remarkable character of the new genus is a deep sub-basal constriction of the pronotum. The morphology of Scydmepitoxis is described and illustrated in detail, and its diagnostic characters are discussed. Possible affinities with Sciacharis and Sciacharoid...

Alpinia galanga Linn. (Willd) is an important raw drug used in large quantities in various indigenous formulations. In this paper the major diagnostic characters and the qualitative chemical and physical tests responsible for the pharmacognostic identity of the rhizomes have been reported.

The paper deals with the detailed pharmacognosy of the whole plant of Orilaitamarai (Hybanthus enneasperms) sold in the local market under the name Purusharatna, Ratanpursuha. The studies include macro, microscopical, histochemical and diagnostic characters of the root, stem and leaf. The physical constants, fluorescence characteristics and chromatographic studies of the whole plant are also pr...

The paper provides a synoptic key to the genera of final instar European Trichoptera larvae. The most important characters are illustrated by colour photos, with arrows highlighting the diagnostic features. A short descriptive text gives additional information for each decision and guides the reader through the determination process.

A new species of the Oriental genus Elacatophora, E. euconnoides sp. n., is described from the Cameron Highlands, West Malaysia. Diagnostic characters, including the male genitalia, are illustrated and discussed. A new case of subjective synonymy was discovered: Elacatophora minae (Makhan & Ezzatpanah, 2011) is placed as syn. n. of E. soesilae (Makhan & Ezzatpanah, 2011). 

American Entomologist • Winter 2008 Unlike pathway and multiaccess keys, which use diagnostic morphological characters, NemaScope uses point-and-click visual matching that allows users to navigate through a collection of images until images similar to specimens under investigation are found. High-definition multifocal images of genera provide the basis for the initial photos and can be viewed w...
