Characters in the book lungs of Scorpiones (Chelicerata, Arachnida) revealed by scanning electron microscopy

“…Some of these characters have been noted previously (e.g. Berteaux 1889; Laurie 1896aLaurie , 1896bPavlovsky 1926;Rö dl et al 1989), and even proposed as taxonomic characters. For example Laurie (1896a) provisionally recognised higher taxa defined by 'spinous', 'arcade' and 'reticulate' types of book lung (see Discussion).…”

Phylogeny of theNorthAmerican vaejovid scorpion subfamilySyntropinae Kraepelin, 1905, based on morphology, mitochondrial and nuclearDNA

“…The taxonomic history of the subfamily, discussed further below, is inextricably linked to that of the family Vaejovidae Thorell, , the generic composition of which has undergone considerable modification since first proposed (Thorell, ; Pocock, ; Laurie, ,b; Kraepelin, ; Stahnke, ; Francke and Soleglad, ; Sissom, , ; Stockwell, ; Soleglad and Fet, , , , ; Graham and Soleglad, ; Francke and Ponce‐Saavedra, ). Vaejovidae are currently restricted to North American taxa, but the monophyly and composition of the family, like that of its component genera and suprageneric taxa, have not been satisfactorily tested.…”

Redefinition and Generic Revision of the North American Vaejovid Scorpion Subfamily Syntropinae Kraepelin, 1905, with Descriptions of Six New Genera

“…Consequently, many Syntropinae are endemic to particular geological formations (e.g., isolated mountain ranges and sand systems), and occupy restricted distributional ranges (Williams, 1980). The taxonomic history of Syntropinae, discussed further below, is inextricably linked to that of the family Vaejovidae Thorell, 1876, the generic composition of which has undergone considerable modification since first proposed (Thorell, 1876;Laurie, 1896;Pocock, 1893;Kraepelin, 1905;Stahnke, 1974;Francke and Soleglad, 1981;Sissom, 1990Sissom, , 2000Soleglad and Fet, 2003, 2008Graham and Soleglad, 2007;Francke and Ponce-Saavedra, 2010). Vaejovidae is currently restricted to North American taxa, but its monophyly and composition, like that of its component genera and suprageneric taxa, was not satisfactorily tested until recently.…”
