Lectotype designation are provided for five species described by Germar: Cerambyx (Lissonotus) gagatinus Germar, 1824, Callichroma rufiventre Germar, 1824, Cerambyx lyciformis Germar, 1824, Rhinotragus dorsiger Germar, 1824, Callidium (Clytus) bisignatus Germar, 1824 and seven described by Klug: Stenopterus crinitus Klug, 1825, Stenopterus hirtipes Klug, 1825, Molorchus scoparius Klug, 1825, St...

In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp...

Following optic nerve crush in the adult lizard Ctenophorus ornatus, most retinal ganglion cells regrow their axons into visual brain centres: however, the regenerated projections lack retinotopic order and the animals are blind via the experimental eye. Here we have used 3H-thymidine autoradiography to demonstrate that cell division is no longer taking place in the retina of normal adult lizar...

Survey work from 1992-2001 identified 139 species of hispines at the lowland part of La Selva Biological Station, Costa Rica. The tribe Cephaloleiini was the most speciose with 58 species (41.7%) followed by the Chalepini with 55 (39.5%). The fauna is most closely related to that in South America but with some genera which are more speciose in the Nearctic Region. Plant associations are known f...

Two new species of oribatid mites the genus Xenillus (Oribatida, Liacaridae) are described from leaf litter in a rain forest Bolivia. pseudobolivianus sp. n. is similar to X. bolivianus and neonominatus morphology lamellar cusp, length bothridial interlamellar setae dorsal notogastral setae, but differs both by head ornamentation notogaster, different some setae. amboroensis amazonensis, disjun...

The Nearctic fauna (north of Mexico) of Eustrophinae is reviewed, and consists of the following five genera and 12 species: Pseudoholostrophus (Pseudoholostrophus) impressicollis (LeConte), Pseudoholostrophus (Holostrophinus) discolor (Horn), Holostrophus bifasciatus (Say), Eustrophus tomentosus Say, Eustrophopsis confinis (LeConte), Eustrophopsis bicolor (Fabricius), Eustrophopsis brunneimargi...

Plectranthus spp (Lamiaceae) are plants of economic importance because they are sources of aromatic essential oils and are also cultivated and several species of this genus are used as folk medicines. This paper describes the effects of different concentrations of the 2,4-dichlorophenoxyacetic acid (2,4-D) and 1-naphthaleneacetic acid (NAA) on the induction of callus from nodal segments of Plec...
