“…The new species cover the whole spectrum of different combinations present in the group, and T. quarta sp.n. , with eight (4 + 4) setae, increases the disparity and raises an interesting question: The presence of eight setae in the umbilicate series is commonly interpreted as a basal feature (Jeanne, 1973; Serrano & Aguiar, 2006a,b; Zaballos & Pérez‐González, 2011a,b) and has only been known in the silvanoides group of species until now. Both species groups ( silvanoides and baetica ) share many morphological characters such as the general shape of the pronotum and elytra, the presence of a stridulatory organ, the shape of the metatrochanter, the dilated distal end of the metatibiae or the shape of last ventrite (lacking lateral teeth).…”

Four new species of Typhlocharis (Carabidae: Anillini) are described from the southwest of the Iberian Peninsula, assigned to the baetica species group. T. primasp.n., T. secundasp.n. and T. tertiasp.n. (from La Palma del Condado, Huelva, Spain) are syntopic, and T. quartasp.n. (from Barrancos, Beja, Portugal) is the first species of the group with umbilicate series 4 + 4. They represent, respectively, the southernmost and westernmost distribution data for the group. The baetica group remains well defined and includes ten species. The diagnosis is simplified, with the confirmation that many morphological features characteristic of this group are widespread within the genus. The defining character is the presence of denticles in apical margin of elytra, not associated to the seventh stria or to the elytral suture. The new species provide morphological data that suggest the baetica and silvanoides groups are closely related. Distribution of both groups in the south of the Iberian Peninsula and the presence of morphological characters that are considered plesiomorphic are coherent with the hypothesis of betic‐riffain origin of the genus. They also support the hypothesis of easy alteration of the umbilicate pattern between closely related species and the independent origin of apical denticles in the group compared with those present in other species of the genus. The presence of three well‐differentiated size ranges in syntopic populations suggest ecological diversification to avoid interspecific competition.

“…The male genitalia of the new species is slightly different from T. fozcoaensis concerning the sclerites of the internal sac (lateral and dorsal views) and the left paramere shape (lateral view), but the median lobe presents some shape similarity in lateral view (cf. Figures 13, 14 in this work and figure 3c, d in Serrano et al 2005). The female genitalia of T. zaballosi n. sp.…”

“…T. paulinoi , T. hiekei , T. atienzai ). It should be noted that all of these species coexist with other species of Typhlocharis (Zaballos and Farinós, ; Magrini, ; Serrano and Aguiar, ), suggesting that unique features in aedeagus might act as mechanisms of reproductive isolation.…”

“…This led to four situations, where we follow the “open nomenclature” criteria (Bengston, ): The specimen clearly belongs to an already described species. It is labelled with a voucher code followed by the name of the species, such as “BMNH‐1046040‐ Typhlocharis lunai Serrano and Aguiar, ”. The specimen probably belongs to a known species but cannot be totally verified with the available data. It is labelled as “ cf .” (from latin “ confer ” – compare) plus the name of the presumed species, for example “BMNH‐1041970‐ Typhlocharis cf.…”

“…The increasing interest in this genus over the last 20 years has resulted in an unprecedented discovery rate of new species (Zaballos and Pérez‐González, ); and morphological descriptions have progressively become more detailed, adding previously ignored characters (e.g. Zaballos and Ruíz‐Tapiador, ; Zaballos and Wrase, ; Zaballos and Banda, ; Serrano and Aguiar, ). Some of these characters, such as antennae or tarsomeres, turned out to be good taxonomic tools (Pérez‐González and Zaballos, ,c); others are probably diagnostic, too, but this remains to be evaluated.…”

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

Typhlocharis is the most diverse eyeless endogean ground beetle genus known to date, with 62 species all endemic to the West Mediterranean region. The lineage is characterized by a conservative and singular body plan within Carabidae that contrasts with a high morphological diversity in many traits. We provide an exhaustive phylogeny of the lineage through the study of 92 morphological characters from all 62 described species and 45 potential new species from 70 additional populations, and the combination of morphological and available molecular data, in the first total evidence phylogenetic approach for a highly diverse endogean lineage. We tracked the evolution of morphological traits over the obtained phylogenies. Results suggest eight morphologically distinct clades, which do not correspond to the species groups proposed formerly. Ancestral state reconstructions and phylogenetic signal analyses of morphological traits revealed that some of the previously key characters to the classification of Typhlocharis, such as the umbilicate series or the apical denticles of elytra, are highly homoplasic, whereas other characters show stronger phylogenetic signal, including structures in the antennae, gula, pronotum and last abdominal ventrite. This evidence supports the split of Typhlocharis into three genera: Lusotyphlus gen. nov.; Typhlocharis Dieck, 1869 and Microcharidius Coiffait, 1969 (revalidated), forming the subtribe Typhlocharina Jeanne, 1973.
