<i>Typhlocharis algarvensis</i> Coiffait, 1971: redescripción y afinidades (Coleoptera, Caraboidea, Trechidae)

Abstract

Se actualiza la descripción de Typhlocharis algarvensis Coiffait, 1971 incluyendo caracteres desconocidos para la especie como la genitalia masculina y femenina, pars stridens, dimorfismo sexual, pelo mesotibial y ojales de los élitros. Se discuten las afinidades taxonómicas de la especie y el valor taxonómico de la serie umbilicada de los élitros y la forma de los gonocoxitos a la hora de establecer los grupos de especies en el género.

A new species of Typhlocharis Dieck, 1869 (Coleoptera: Carabidae: Anillini) from South Spain, with notes on the phylogenetic value of sexually related characters and the presence of stridulatory organ (pars stridens) in the genus

“…The new species shares certain traits with other species that are supposed to be not closely related, which suggests a reinterpretation of the species groups as currently known. Traditionally, there have been some key morphological traits used to classify the different species into several well defined species groups (Zaballos & Ruíz-Tapiador 1997), but recent research gives some evidence that these are not natural groups and do not reflect the true phylogenetic relationships of the genus (Andújar et al 2010, Zaballos & Pérez-González 2010. However, those groups are still useful to identify and work with taxa of this large genus.…”

“…The genus Typhlocharis currently includes 50 species (Andújar et al 2010) of very small endogean carabid beetles (from the 0.9 mm of Typhlocharis quadridentata Coiffait, 1969 to the 2.9 mm of Typhlocharis carinata Serrano and Aguiar, 2006). Most of these species have been described during the last 20 years (Zaballos and Pérez-González 2010). The special traits of this genus (Jeannel 1937) gave Dieck (1869) the impression that they should be included in Cucujidae, probably related with Laemophloeus Dejean, 1835 (today a member of its own family, Laemophloeidae, Cucujoidea), and Marseul (1873) maintained this opinion.…”

<i>Typhlocharis</i> vicariantes del Estrecho de Gibraltar. II: <i>T. silvanoides</i> Dieck, 1869 (Coleoptera, Caraboidea, Trechidae)

“…Dentro del grupo silvanoides, se asemeja en la forma general del cuerpo a T. algarvensis, pero se diferencia de ésta en la ausencia de pelo mesotibial y ausencia de setas discales y apicales en los élitros, así como por la particular seta hipertrofiada del parámero derecho de T. algarvensis (Zaballos & Pérez-González, 2010a). De T. carinata se diferencia por la ausencia de la carena ventral en los machos, ausencia de setas discales y menor tamaño, así como en la forma del edeago y los paráme-ros (Serrano & Aguiar, 2006).…”

Hidden biodiversity: total evidence phylogenetics and evolution of morphological traits in a highly diverse lineage of endogean ground beetles,TyphlocharisDieck, 1869 (Carabidae, Trechinae, Anillini)

“…The increasing interest in this genus over the last 20 years has resulted in an unprecedented discovery rate of new species (Zaballos and P erez-Gonz alez, 2010); and morphological descriptions have progressively become more detailed, adding previously ignored characters (e.g. Zaballos and Ru ız-Tapiador, 1997;Zaballos and Wrase, 1998;Zaballos and Banda, 2001;Serrano and Aguiar, 2006).…”
