Megalota Diakonoff, 1966 is reported from China for the first time. Two new species, M. bicepsunca, sp. nov., and M., curvativa, sp. nov., are described and illustrated based on the male adults, both of them are distributed in south China Photographs of the adults and male genitalia are provided.

In a state of voluntary trance or meditation, the perception of reality appears to extend beyond the usual spatial and temporal boundaries that are normally perceived by the sense organs. It is argued that the problems of validity and reliability of trance experiences for scientific discourse are in principle no different than the problems associated with ordinary perception. The shift in early...

We have examined the early pattern of sensory mother cells in embryos mutant for six different neurogenic loci. Our results show that the neurogenic loci are required to restrict the number of competent cells that will become sensory mother cells, but are not involved in controlling the localization or the position-dependent specification of competent cells. We conclude that these loci are invo...

Anabarhynchus Macquart 1848 is a large genus of the Therevidae (Diptera) that are endemic to Australasia with a couple of described species from Melanesia. We describe and illustrate Anabarhynchusoceanus sp. n., a species found on ocean beaches in eastern Victoria, Australia. The species shares most characters with the monobasic Anabarhynchuskampmeierae species group of Lyneborg (2001), but als...

The homeotic genes are instrumental in establishing segment-specific characteristics. In Drosophila embryos there is ample evidence that the homeotic genes are involved in establishing the differences in the pattern of sense organs between segments. The chordotonal organs are compound sense organs made up of several stretch receptive sensilla. A set of serially homologous chordotonal organs, lc...

The tegula is a complex, knob-shaped sense organ associated with the base of the locust wing. Despite a detailed knowledge of its role in flight motor control, little is known about the relationship between the stroke parameters of the wing, movement of the tegula organ and the pattern of tegula activity. In this study, therefore, the kinematic parameters of the fore- and hindwings were investi...

Paraportanus longispinus,, a new leafhopper species from Roraima and Amazonas States, North Brazil, is described and illustrated. The new species can be recognized by the male genital features, especially the distal third of ventral margin of the pygofer with a dentiform short process; plates distinctly longer than pygofer, extending posteriorly beyond pygofer by approximately 1/3 of their leng...

Vision is critical for the functional and structural maturation of connections in the mammalian visual system. Visual experience, however, is a subset of a more general requirement for neural activity in transforming immature circuits into the organized connections that subserve adult brain function. Early in development, internally generated spontaneous activity sculpts circuits on the basis o...

The dictyopharid planthopper genus Anasta Emeljanov from the Australasian region is revised to include six species including a new one: A. australiaca (Lallemand, 1935) comb. nov. (North Australia), A. lobosa sp. nov. (Papua New Guinea), A. minuta (Lallemand, 1935) comb. nov. (Timor, Indonesia), A. prognatha (Distant, 1906) (North Australia, Papua New Guinea), A. timorina (Lallemand, 1935) (Tim...

A new species of so far monospecific genus Siamites, S. complicatus sp. n., is described. The type specimens were collected in the Krabi Province of Thailand. Morphology of the new species is described and illustrated in details, including male genitalia, and the distribution of Siamites is summarized.
