Description of a new hypogean species of the genus Trechus Clairville, 1806 from eastern Spain and comments on the Trechus martinezi‐lineage (Coleoptera: Adephaga: Carabidae)

Trechus torressalai new species, a cave‐dwelling ground beetle from eastern Spain is described. Ecological data are also included. Diverse morphological characters suggest they belong in the Trechus fulvus‐group. Detailed study of the aedeagus suggests taxonomic affinities with Trechus martinezi Jeannel, Trechus alicantinus Español, and Trechus beltrani Toribio. The close relationship among these species reveals an adelphotaxon‐complex that constitutes the T. martinezi‐lineage, exclusive to the north‐eastern Betic Mountains. An identification key to the species and biogeographical comments on the T. martinezi‐lineage are also included.

Se describe Trechus torressalai nueva especie, carábido cavernícola del Este de España. Se incluyen datos sobre su ecología. Diversos caracteres morfológicos aconsejan su inclusión dentro del amplio grupo de Trechus fulvus. El estudio detallado de la genitalia masculina sugiere su proximidad taxonómica a Trechus martinezi Jeannel, Trechus alicantinus Español y Trechus beltrani Toribio. Las estrechas afinidades entre estas cuatro especies desvela un complejo de adelfotaxones que constituyen el linaje de T. martinezi, exclusivo del extremo nororiental de las montañas Béticas. Se aportan claves de identificación para estas especies. Se incluyen comentarios sobre la biogeografía del linaje de T. martinezi.

Three new endogean species of Laparocerus Schönherr, 1834 from the Canary Islands (Coleoptera,Curculionidae)

Three new species of the weevil genus Laparocerus Schönherr (1834) adapted to the edaphic environment of the Canary Islands are described: L. edaphicus n. sp., L. oromii n. sp. and L. lopezi n. sp. They live in the humid laurel forests of Tenerife (Anaga Mountains), La Gomera (Garajonay National Park) and Gran Canaria (Valsendero), respectively. The small size and somewhat tubular body shape is a common character among them, as is the reduction of the eyes, which are totally absent in L. oromii n. sp. Despite these common adaptive traits, the three species seem not to be directly related. A key for the identification of all the known cryptozoic (edaphic and troglobitic) species of Laparocerus is provided.     

Two new South American species of Acrobelus Stål (Hemiptera: Cicadellidae: Cicadellinae) with a key to the species of the genus

Two new leafhopper species of the Neotropical genus Acrobelus Stål, 1869 are described and illustrated: A. nessimiani sp. nov. from Peru (Amazonas Department) and A. rakitovi sp. nov. from Ecuador (Orellana Province). The two new species, distinguished from the other Acrobelus species by their remarkably long male subgenital plates and by the fusiform macrosetae present on these plates, seem to be closely related. A key to male specimens of the five known species of Acrobelus is provided. Taxonomic notes on the genus are included.
