Review of the Classification of the Orders of Arachnida

Solifuge (camel spider) reproductive biology: an untapped taxon for exploring sexual selection

“…In the search for relatively unexplored animal taxa that might contribute significantly to our understanding of sexual selection's role in evolution, solifuges (Order Solifugae) appear to be a promising group. Solifuges encompass a fairly diverse order that inhabits mainly arid and semi-arid zones (Maury 1980(Maury , 1998Beron 2018). Similar to other arachnid groups mentioned previously, solifuges display a range of different mating strategies and have a number of interesting sexually dimorphic traits that make them attractive study organisms for both comparative and experimental purposes.…”

“…Historical overview.-There are published data on mating behavior for 17 species belonging to only five out of 12 extant families of this fantastic group of arachnids (with more than 1000 described species in about 140 genera) (Prendini 2011;Bird 2015;Beron 2018): (i) Galeodidae Sundervall, 1833, (ii) Solpugidae Leach, 1815, (iii) Eremobatidae Kraepelin, 1901, (iv) Ammotrechidae Roewer, 1934, and(v) Daesiidae Kraepelin, 1899 (see Supplementary Table S1, online at https://doi. org/10.1636/JoA-S-20-037.s1).…”
