Paratemnoides assimilis is most similar to P. pallidus (Balzan, 1892) as both possess similar proportions of the palpal segments (femur 0.62-0.83 mm long/2.10-2.30 x longer than broad, patella 0.59-0.78 mm long/1.80-1.90 x longer than broad, chela 1.27-1.44 mm long/2.40-2.70 x longer than broad, finger 0.47-0.63 mm long), minute denticles on the palpal segments while other body segments are smooth, and a carapace without transverse furrows. They differ by the presence of minute denticles on different segments of the pedipalps; in P. assimilis denticles are present on the anterior margin of the palpal femur, but with other palpal segments smooth, but in P. pallidus denticles are present on femur as well as on patella ( Beier 1932a , 1932b ; Mahnert 1978a ; Harvey 1988 ). Measurements of the palpal hand with pedicel also differ ( P. assimilis 0.62-0.83 mm long vs P. pallidus 0.80-1.06 mm long) ( Mahnert 1978a ; Harvey 1988 ). Remarks. New-found specimens of P. assimilis were compared with selected Paratemnoides species deposited in NHMW: P. assimilis [NHMW-Zoo-AR 25115, NHMW-Zoo-AR 25124]; P. ceylonicus Beier, 1932 [NHMW-Zoo-AR 25064, NHMW-Zoo-AR 25065]; P. curtulus (Redikorzev, 1938) [NHMW-Zoo-AR 25117]; P. laosanus (Beier, 1951) [NHMW-Zoo-AR 25073]; P. pallidus [NHMW-Zoo-AR 25090, NHMW-Zoo-AR 25125]; and P. salomonis (Beier, 1935) [NHMW-Zoo-AR 25110]. As mentioned by Harvey (1988) , the identification keys to Paratemnoides species by Beier (1932a , 1932b ) are based generally on the size or thickness of palpal segments and legs. Harvey (1988) applied the character of measurements of leg segments as distinguishing ones for P. assimilis and P. ceylonicus . Specimens of species mentioned above were examined and compared in this study. Leg segments were measured but the values completely overlapped in all examined species. Considering these results and the fact that the Paratemnoides species descriptions are generally not sufficient, a revision of this genus is necessary to clearly set species boundaries. Currently, P. ceylonicus is one of the synonyms of P. pallidus (Fig. 2B ) ( Klausen 2005 ; WPC 2022 ). The current synonymy of the two species was justified by no significant difference between P. ceylonicus and P. pallidus in palpal chela measurements ( Klausen 2005 ). Beier (1932a , 1932b , 1973 ) supported the existence of P. ceylonicus by the presence of minute denticles on the anterior margin of the palpal femur while other palpal segments are smooth. All examined specimens of P. ceylonicus deposited in NHMW possess distinct granulation present on palpal femur as well as on patella just like in P. pallidus . The present study supports the synonymization of P. ceylonicus with P. pallidus suggested by Klausen (2005) . Family Geogarypidae Chamberlin, 1930 Genus Geogarypus Chamberlin, 1930
