The reconstruction of scrotal skin following trauma, infection or congenital anomalies of the genitalia often poses great difficulty for the plastic surgeon. The bacterial flora of the area, the peculiar anatomy of the male genitalia and the need for maintenance of testicular function in a normal, thermoregulatory space narrow the reconstructive alternatives and make aesthetic scrotal reconstru...

Three new species of the bamboo-feeding genus Bambusiphaga Huang & Ding, 1979, B. parvula sp. nov., angulosa and nigrigena are described illustrated from China. A key to is provided. Habitus photos for adults illustrations male genitalia also given.

background: x-linked lissencephaly with ambiguous genitalia (xlag) is a recently described genetic disorder, in which patients present with lissencephaly, agenesis of the corpus callosum, refractory epilepsy of neonatal onset, acquired microcephaly, and male genotype with ambiguous genitalia. xlag is responsible for a severe neurological disorder of neonatal onset in boys. a gyration defect con...

There have been relatively few electrophysiological studies, in any species, describing the supraspinal processing of inputs from the male genital tract. The thalamus was the focus of the present study. In 11 urethan-anesthetized male rats, subregions of the thalamus were surveyed for neuronal responses to the search stimulus, bilateral electrical stimulation of the dorsal nerve of the penis (D...

This study elucidates the homology of elements of the male palps in the spider family Theridiidae. We survey and illustrate 60 species from 29 out of the 86 currently recognized genera representing all subfamilies. The study is buttressed by a phylogenetic framework, and uses a new method to evaluate critically competing homology hypotheses based on various criteria. Among the classic criteria ...

Exocelina baliem sp. n. is described from the Baliem Valley in the Central Mountain Range of New Guinea (Papua Province, Indonesia). Having striolate elytra, different structure and setation of the male and female genitalia and tarsomeres, and inhabiting swampy ponds, the new species differs from all known New Guinea species, which have smooth elytra and are stream associated. It forms a monoph...

A new malachiid beetle species Kuatunia andreasi Tshernyshev, sp. n. is described from Nepal (Karnali Province). Figures of the external appearance, elytral apices, and genitalia male are provided for species. key to all genus Evers, 1949 given.

The leading hypothesis for the evolution of male genital complexity proposes that genital traits evolve in response to post-insemination sexual selection; that is, via cryptic female choice or sperm competition. Here, we describe a laser ablation technique for high-precision manipulation of microscale body parts of insects, and employ it to discern the adaptive function of a rapidly evolving an...
