Sabethes (Peytonulus) luxodens, a new species of Sabethini (Diptera: Culicidae) from Ecuador.
The adult male, larva and pupa of Sabethes (Peytonulus) luxodens, a new species from Ecuador, are described. The species is distinguished from Sabethes aurescens (Lutz), which it closely resembles in all life stages.

Age, gesture span, and dissociations among component subsystems of working memory.
Working memory was examined in old and young adults using a series of span tasks, including the forward versions of the visual-spatial and digit span tasks from the Wechsler Memory Scale-Revised, and comparable hand gesture and visual design span tasks. The observation that the young participants performed significantly better on all the tasks except digit span suggested that aging has an impact on some component subsystems of working memory but not others. Analyses of intercorrelations in span performance supports the dissociation among three component subsystems, one for auditory verbal information (the articulatory loop), one for visual-spatial information (visual-spatial scratch-pad), and one for hand/body postural configuration.
