03CF87DFCA37FF9593EFFECD9F2EEDED.taxon	discussion	Remarks. In view of the similar shape of the idiosoma (e. g. idiosoma and genital field elongated, dorsal shield L / W> 1.5, genital field L / W ratio> 1.4, excretory pore on the line of primary sclerotization) and palps, these specimens show a general conformity with Monatractides nipsanicus Pešiċ & Smit 2011, a species known only from a single male specimen from the Nipsan district in Papua province (Pešiċ & Smit 2011). Differences are found in the major idiosoma and gnathosoma dimensions and the considerably elongated genital field (L / W ratio 1.6) in the holotype of M. nipsanicus. Study of more material of the latter species from the locus typicus is necessary before a decision can be made whether specimens from West Papua represent an undescribed ‘ western’ sister species of M. nipsanicus or our data enlarge the known variability of the latter.

03CF87DFCA32FF9793EFFAB99B84EA4E.taxon	discussion	Discussion. Due to the similar shape of palp (straight stout seta on the ventral margin of P- 2 and P- 3) and the excretory pore incorporated into primary sclerotization of the ventral shield, Monatractides magnus sp. nov. is rather close to M. sentanicus Pešiċ & Smit, 2011 (see above). It can be distinguished from the latter species in its larger idiosoma and gnathosoma dimensions (e. g. idiosoma L> 1000, genital field L> 200, palp total L> 270 vs. idiosoma L <700, genital field L <150, palp total L <220 in M. sentanicus) and a more slender and relatively longer, straight stout seta on the ventral margin of P- 2 (compare Figs. 3 C and 5 A – B).	en	Pešić, Vladimir, Smit, Harry (2012): Second contribution to the knowledge of water mites of the genus Monatractides K.

Named for its resemblance to Monatractides australicus (Cook, 1986).	en	Pešić, Vladimir, Smit, Harry (2012): Second contribution to the knowledge of water mites of the genus Monatractides K.

03CF87DFCA30FF9893EFF98B9E6AEE1E.taxon	discussion	Discussion. Monatractides neoaustralicus sp. nov. and M. rivulus sp. nov. (see below) belong to the M. macroporus (K. Viets, 1935) species-complex (see: Pešiċ & Smit 2009). Due to the general shape of idiosoma and palp, M. neoaustralicus sp. nov. most closely resembles M. australicus (Cook, 1986), a species widespread in Australia (Pešiċ & Smit 2012). The latter species differs from M. neoaustralicus sp. nov. (and other species of the macroporus - complex from New Guinea) in the excretory pore lying in an indentation of the line of primary sclerotization, while the area of primary sclerotization generally extends more to the posterior margin of the ventral shield, and consequently, Vgl- 2 is shifted less away from the excretory pore. Moreover, P- 2 and P- 3 have more slender, hair-like ventral setae. Two other previously described members of the macroporus - group from New Guinea, Monatractides humilis Pešiċ & Smit 2011 and M. alticolus Pešiċ & Smit, 2011, can be distinguished in the male by a more elongated genital field (L / W ratio 1.4 – 1.5 in M. humilis and M. alticolus vs. 1.2 in M. neoaustralicus sp. nov.). Other differences are the well pronounced denticle near the insertion of the ventral hairs in M. humilis and the major idiosoma and gnathosoma dimensions in M. alticolus.	en	Pešić, Vladimir, Smit, Harry (2012): Second contribution to the knowledge of water mites of the genus Monatractides K.

Named for living in a small stream.	en	Pešić, Vladimir, Smit, Harry (2012): Second contribution to the knowledge of water mites of the genus Monatractides K.

03CF87DFCA3FFF9893EFFD5B9E69EB43.taxon	discussion	Discussion. Due to the elongated idiosoma (e. g., dorsal shield L / W> 1.5), the broad frontal platelets (L / W 1.5 – 1.9), dorsal shoulder plates swollen anteriorly, relatively long suture line of Cx- 2 + 3 (L 100 μm) and a moderately elongated genital field (L / W ratio 1.3 – 1.4), Monatractides rivulus sp. nov. can be easily distinguished from the other members of the M. macroporus species-complex.	en	Pešić, Vladimir, Smit, Harry (2012): Second contribution to the knowledge of water mites of the genus Monatractides K.
