The genus is recognized by small-sized idiosoma, well-developed idiosomal plates, alveolous pores on anterior dorsal plate, large epimeral vesicles on anterior epimeral plate, three segmented palps and enlarged and armoured leg I with spine like projection ( + +Pepato +et al +. 2004 + +; +Bartsch 2006 +). +Durucan and Boyaci (2017) +reported this species under the name of + +Atelopsalis pacifica +Bartsch, 1985 + +for the Turkish halacarid fauna, but after careful re-examination, the present identified this species as + +Atelopsalis mediterranea + + +sp. nov. + +in this study. + + +At a first glance, the new species, + +Atelopsalis mediterranea + + +sp. nov. +, + +is similar to + +A. pacifica + +and + +A. tricuspis + +due to similar raised areolae on idiosoma dorsal, ventral and gnathosoma ventral, rosetta pores wides on AD and PD ( +Bartsch 1973 +). However, + +A. mediterranea + + +sp. nov. + +clearly differs from both species by having much longer setae especially on OC, AE, PE and leg I and II (see arrowheads on +Figs. 4G, H +). Solenidion II (14) ( +Fig. 4L +) is also clearly much longer than + +A. pacifica + +and + +A. tricuspis + +. There are also disparities between + +A. pacifica + +and the new species, according to +Bartsch (2007) +, there is a single pore on AE at the level of the epimeral vesicles in + +A. pacifica + +while there are 5–10 pores on AE at the level of the epimeral vesicles in the new species, the frontal process are not extending anteriorly in the new species both adults and deutonymph while this frontal process clearly extending anteriorly in + +A. pacifica + +. The new species has one spiniform lamella on telofemur I ( +Fig. 5B +), while two spiniform lamellae on telofemur I in + +A. pacifica + +. + + +The new species is distinguished from + +A. atlantica + +by having larger areolae on OC, shorter frontal process, narrower costae on AD and PD, less number of areolae between epimera I and II and posterior part of AE. + +A. zanzibari + +can be easily distinguished from any species of the genus having four costae on PD and + +A. ridens + +and + +A. newelli + +has no costae on PD of the genus, while the new species has a pair of costae on PD. + +A. meteorensis + +has no rosette pores on ventrolateral part of gnathosoma, while the present new species have rosetta pores on ventrolateral part of gnathosomal base. Additionally, posterior part of OC blunt in + +A. meteorensis + +while OC tapering posteriorly in the new species. + +A. newelli + +is distinguished from the new species by lacking frontal process, cornea on OC and areolae on OC, AE, PE. + +A. aliger + +has no areolae near posterolateral area of AE, while the new species have areolae posterolateral of AE (Chattejee +et al. +2009). + + + + \ No newline at end of file
