A new genus of Hubbardiidae (Arachnida: Schizomida) from the Colombian Andes, with some taxonomic comments

Abstract

A new genus, Calima, and two new species, C. bremensis and C. valenciorum, of Hubbardiidae are here described,respectively from Bremen Forest, Filandia, Quindio department and Andinapolis, Trujillo, Valle del Cauca department,both localities located in the Colombian Andes. A comprehensive map of the South American species with a four-segmented female flagellum is presented, tables with characters of New World Hubbardiidae genera are provided. The relationships of the new genus within neotropical Hubbardiidae fauna is discussed.

A new species of Piaroa (Schizomida: Hubbardiidae) from Venezuela, with taxonomic notes on the genus

“…In the case of P. guipongai, the presence of only two enlarged lobes and the shape of the chitinous arc, besides other characters like the male flagellum and cheliceral setation, confirm its position inside this genus. The absence of two lobes in Piaroa is also shared by other neotropical genera, Calima and Adisomus Reddell, 2000 (Cokendolpher andReddell 2000;Moreno-González and Villarreal 2012).…”

“…Since then, their morphology has become widely accepted and included in schizomid taxonomy (Reddell and Cokendolpher, 1995). The importance of this structure in schizomid identification has been shown on some genera like Calima and Piaroa, where other characters like the male flagellum were not conclusive to define the genus Moreno and Villarreal 2012). In the case of P. guipongai, the presence of only two enlarged lobes and the shape of the chitinous arc, besides other characters like the male flagellum and cheliceral setation, confirm its position inside this genus.…”

“…genera of Hubbardiinae but since they are small, these and other setae might have been overlooked previously. Only some descriptions on the genera Bamazomus Harvey, 1992;Paradraculoides Harvey, Berry, Edward and Humphreys, 2008;Draculoides Harvey, 1992 and Calima for example, illustrate the full set of setae present on flagellum including microseate (Harvey and Humphreys 1995, Harvey 2001, Harvey et al 2008, Moreno-González and Villarreal 2012. According to this, detailed observations on chaetotaxy like those provided by SEM images should be used on the descriptions of new schizomid species.…”

Systematics of the genusMayazomus(Arachnida: Schizomida): the relevance of using continuous characters and pedipalp setae patterns to schizomid phylogenetics

“…(), specifically those of the relative position of the macrosetae and the presence of microsetae on the female flagellum. Characters of the male flagellum relief are modified from Rowland (), following the nomenclature of Moreno‐González & Villarreal (). For the spermathecae, we used the characters proposed originally by Rowland () and Reddell & Cokendolpher () with some modifications and including the proposals of Moreno‐González et al .…”

“…(Harvey, , , , ; Villarreal & Teruel, ; Harvey et al ., ). Other important characters are the relief of the dorsal surface of the flagellum as first proposed by Rowland (), and subsequently standardized by Reddell & Cokendolpher () and Moreno‐González & Villarreal (). Finally, the general shape of the flagellum is a very variable character amongst genera and families, and here we propose the implementation of morphometric ratios to assess homology of the male's flagellum shape to compare directly the same part (see continuous characters).…”
