Belongs within: Elassommatina. The Cheliferinae are a group of pseudoscorpions in which the cheliceral flagellum is composed of three setae, and coxal sacs are present in the fourth coxae of males. <==CheliferinaeMHG08 |–Nannochelifer Beier 1967MHG08, H09 |–Protochelifer victorianusMHG08 `–Chelifer Geoffroy 1762H02 |–C. argentinus Thorell 1887T89 |–C. bicolor Risso 1826R26 |–C. bifissusS99 |–C. birmanicus Thorell 1889T89… Continue reading Cheliferinae


Belongs within: Panctenata.Contains: Sternophoridae, Cheiridioidea, Chernetidae, Cheliferinae, Atemninae, Withiidae. The Elassommatina is a clade of pseudoscorpions including species in which all legs have five post-coxal segments (with the tarsus undivided), and which have two or no eyes (Muchmore 1990). <==ElassommatinaMHG08 |–+–SternophoridaeMHG08 | `–CheiridioideaMHG08 `–Cheliferoidea [Miratemnidae]MHG08 | i. s.: Levichelifer [incl.

Belongs within: Euchelicerata.Contains: Chthoniidae, Iocheirata. The Pseudoscorpiones are a group of small arachnids, superficially resembling scorpions due to the possession of large chelate pedipalps but lacking the elongate metasoma or posterior sting of a scorpion. Characters (from Muchmore 1990): Body divided between anterior prosoma (cephalothorax) and posterior opisthosoma (abdomen), with the two sections broadly connected.… Continue reading Pseudoscorpiones


Belongs within: Panctenata.Contains: Olpiinae, Garypidae. The Olpioidea was recognised by Harvey (1992) for the families Menthidae and Olpiidae on the basis of the presence of trichobothria on the pedipalpal femur. However, molecular phylogenetic analysis suggests that the Garypidae also fall within the clade formed by these families (Murienne et al. 2008). <==Olpioidea |–MenthidaeH06 | |–OligomenthusH06… Continue reading Olpioidea


Belongs within: Iocheirata.Contains: Olpioidea, Elassommatina. The Panctenata are a clade of pseudoscorpions characterised by features of the chelicerae, including the presence of a velum (though this is absent in some olpioids) and lamina exterior (Harvey 1992). Synapomorphies (from Harvey 1992): Velum present; lamina exterior present; movable cheliceral finger with one or two distal teeth or… Continue reading Panctenata


Belongs within: Pseudoscorpiones.Contains: Tyrannochthoniini. The Chthoniidae are a group of pseudoscorpions characterised by differing number of segments in the anterior and posterior pairs of legs (five post-coxal segments in legs I and II vs six in legs III and IV) (Muchmore 1990). Three families have been recognised within the superfamily Chthonioidea, the Chthoniidae, Lechytiidae and… Continue reading Chthoniidae
