The weevil species Listroderes abditus Enderlein belongs in the subtribe Listroderina. This species had been previously transferred to Antarctobius, based on characters from the adult morphology. However, larval characters suggest that it was placed correctly in Listroderes. A cladistic analysis of this species and nine other rhytirrhinines for which larvae are known was performed, based on 56 morphological characters (32 from larvae and 24 from adults). According to the single cladogram obtained (78 steps, CI = 0.65, and RI = 0.72), L. abditus should be included in Listroderes rather than in Antarctobius. Larval and adult characters were also analysed separately, leading to poorer resolution in comparison with the simultaneous analysis, and suggesting that a stable classification requires the analysis of data from both life stages.
Distribution of LiCl/pilocarpine status epilepticus-induced neuronal damage was studied in the piriform cortex and in adjoining structures in 12-day-old, 25-day-old and adult rats. No distinct structural and neuronal alterations were detected in the basal telencephalon in 12-day-old rats surviving status epilepticus (SE) for one week or two months. In 25-day-old rats a decrease in Nissl staining was evident. There was also cell loss and gliosis in the caudal 2/3 of the piriform cortex, in the superficial amygdaloid nuclei, in the dorsal and ventral endopiriform nucleus and in the rostrolateral part of the entorhinal cortical area. In adult animals, the topography of neuropathological changes in the basal telencephalon was comparable to those in 25-day-old rats. The damage in the caudal 2/3 or caudal half of the piriform cortex in adult rats with survival times one week or two months was characterized by a marked loss of neurons and striking glial infiltration. The thickness of the piriform cortex and superficial amygdaloid nuclei was significantly reduced. In 25-day-old and in adult animals the sublayer IIb and layer III of the piriform cortex was more affected, while sublayer IIa was less damaged. Parvalbumin (PV) immunocytochemistry revealed a significant decrease in the number of PV-immunoreactive neurons in the rostral piriform cortex and in the dorsal claustrum in animals surviving for two months., R.
