Description Of The Larva And Female Genitalia Of Trechus Gamae With Data On Its Ecology, Ana Reboleira, Vicente Ortuño
Description Of The Larva And Female Genitalia Of Trechus Gamae With Data On Its Ecology, Ana Reboleira, Vicente Ortuño
Ana Sofia P.S. Reboleira
The third instar larva and the female genitalia of Trechus gamae Reboleira et Serrano (Coleoptera Carabidae Trechini) are described, illustrated and commented. Larvae and imagos were collected in deep parts of caves from Estremenho karstic massif in the centre Portugal. The work provides the first study on hypogean beetle larvae from Portugal, increasing the knowledge about hypogean microendemic species from the Lusitanic district of the Iberian Peninsula. The morphological diagnostic characters of the female genitalia corroborate the inclusion of T. gamae in the “T. fulvus-group”. Some new data on the ecology of this species are also given.
On The Iberian Endemic Subgenus Lathromene (Coleoptera: Staphylinidae: Paederinae): Description Of The First Hypogean Domene Fauvel, From Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí
On The Iberian Endemic Subgenus Lathromene (Coleoptera: Staphylinidae: Paederinae): Description Of The First Hypogean Domene Fauvel, From Portugal, Ana Reboleira, Fernando Gonçalves, Pedro Oromí
Ana Sofia P.S. Reboleira
Domene (Lathromene) lusitanica n. sp. from Sicó karstic massif in Portugal is described and compared with other species of the subgenus, representing the first hypogean rove beetle from mainland Portugal. A comparison between Domene lusitanica n. sp. and the other species of the Iberian endemic subgenus Lathromene is made using diagnostic characters. An identification key for the males of Lathromene species is presented, and biogeographical and ecological comments are also included. The species of Domene known from the Iberian Peninsula are listed and their distributions are mapped.

Pollution of the aquatic ecosystems by heavy metals is a worldwide problem. In the present study, Clarias batrachus was exposed to Mercury and Chromium for 24, 48, 72 and 96 hrs. The median lethal concentration (LC50) of mercury to C. batrachus for 24, 48, 72 and 96 h of exposure were 1.4 ppm, 1.2 ppm, 1.0 ppm and 0.8 ppm respectively. The median lethal concentration (LC50) of chromium to C. batrachus for 24, 48, 72 and 96 h of exposure were 120 ppm, 115 ppm, 110 ppm and 102 ppm respectively. The acute toxicity levels were derived from LC50 concentrations …
