8545EB45EC0AA01AFF3F886EFEA88330.taxon	discussion	Remarks. According to the original description, in this species “ all scutal surface with small puncta ” (Schluger et al. 1960 c); thus, Schluger did not recognize two types of scutal puncta in G. mirabilis, obviously due to insufficiently precise optics. However, she described such punctation in G. tenella Traub and Morrow, 1955, where this trait is more distinct (Schluger et al. 1960 c, Fig. 63). Gahrliepia mirabilis is similar to G. yangchenensis Chen and Hsu, 1957 and differs from the latter by the presence of nude ventral palpal tibial seta vs. having slender branches; the presence of two types of scutal puncta vs. one type (however, the original description of G. yangchenensis could be inexact in this point); and by a slightly larger scutum (AW = 49 – 56 vs. 42 – 51, PW = 70 – 86 vs. 67 – 79, ASB = 21 – 30 vs. 19, and PSB = 112 – 126 vs. 109) (Chen & Hsu 1957; Li et al. 1997). Gahrliepia mirabilis is also similar to G. eurypunctata Jeu, Yu and Wan, 1983 and differs from it by the presence of nude palpal genual and ventral palpal tibial setae (fPp = B / N / NNN vs. B / B / NNB), slightly smaller scutum (PW = 70 – 86 vs. 86 – 90, PSB = 112 – 126 vs. 136 – 141, SD = 134 – 155 vs. 161 – 170, AP = 40 – 45 vs. 46 – 51), and much shorter scutal setae (AL = 28 – 36 vs. 45 – 53 and PL = 32 – 38 vs. 52 – 54) (Jeu et al. 1983).	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

8545EB45EC04A01EFF3F8FBFFAF083D0.taxon	discussion	Remarks. According to the original description, W. delicatula is similar to W. neosinensis (Hsu and Wen, 1956), but differs in the “ shape of trichobothria (sensilla), position of seta on leg coxa III, nude outer lateral seta on palpal tibia, wider scutum, and other characters ” (Schluger et al. 1960 c). The “ outer lateral seta on palpal tibia ” is actually ventral palpal tibial seta. The difference in its shape (fPp = N / N / NNN in W. delicatula and fPp = N / N / NNB in W. neosinensis) is the most clear difference between these two species. We did not find the difference between these species in the position of coxal seta III. The difference in the shape of sensilla (narrower in W. delicatula than in W. neosinensis) seems reliable, although rather slight. According to our data, the metric differences between these species are as follows: AW = 41 – 49, PW = 52 – 69, SB = 34 – 45, ASB = 22 – 31, SD = 83 – 99, and AP = 42 – 52 in the type series of W. delicatula vs. 33, 41, 29, 20, 82, and 38 in W. neosinensis, respectively (Hsu & Wen 1956; Li et al. 1997). The species W. tianguangshanensis Zhao, 1981, which was described from a single specimen ex B. bowersi from Guangdong Province of China, does not differ from W. delicatula, neither by morphology, nor by measurements (Table 2), and therefore is synonymized here with the latter. Specimens Nos 1 and 2 on the slide ZMMU Tdt- 3237 belong to Walchia pacifica (Chen and Hsu, 1955).	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

8545EB45EC00A001FF3F8FF7FAA58082.taxon	discussion	Remarks. According to the original description, W. dismina is similar to W. kritochaeta Traub and Evans, 1957 and differs from it by longer legs and by the presence of two setae on leg coxa III (fCx = 1.1.2 vs. 1.1.1) (Schluger et al. 1960 c). The latter difference is reliable, but the former one is unclear, as the lengths of legs were absent in the original description of W. kritochaeta (Traub & Evans 1957). However, we found the following additional differences between these species. Walchia dismina has 2 - pronged palpal claw, equal leg claws, and has no eyes, while W. kritochaeta has 3 - pronged palpal claw, unequal leg claws (one claw is very thin, like the empodium), and one pair of eyes. Walchia dismina is also similar in the size and shape of scutum to W. isonychia Nadchatram and Traub, 1964, but differs in the presence of two setae on leg coxa III (vs. one seta), a 2 - pronged palpal claw (vs. 3 - pronged), and by the absence of eyes (vs. eyes 1 + 1). Specimen No. 4 on the slide ZMMU Tdt- 3254, specimens Nos 1, 3, 4, and 5 on the slide ZMMU Tdt- 3255, specimens Nos 2 and 5 on the slide ZMMU Tdt- 3258 belong to Walchia chinensis (Chen and Hsu, 1955). Specimen No. 2 on the slide ZMMU Tdt- 3254 presumably belongs to Walchia disparunguis (Oudemans, 1929).	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

One larva ZMMU XM 14.63 k 1 (specimen 11) ex Maxomys surifer No CT- 63, Vietnam, Dong Nai Province, Dong Nai National Reserve (Cat Tien), 11 ° 24 ′ 42.65 ″ N, 107 ° 23 ′ 8.58 ″ E, 11 November 2014, coll. Yu. V. Lopatina. Remarks. The serrated cheliceral blade and shape of scutum (significantly wider than long, with the distance between sensillum bases almost equal to the distance from sensillum base to the lateral scutal margin) confirm that this species belongs to the genus Cheladonta Lipovsky, Crossley and Loomis, 1955, contrary to the opinion of Vercammen-Grandjean (1968). According to the original description, C. neda is similar to C. micheneri Lipovsky, Crossley and Loomis, 1955 and differs in “ significantly lesser body size, number of dorsal setae, feathered setae on femur and tibia of palps and other characters ” (Schluger et al. 1960 a). Actually, C. neda is most similar to C. brevipalpis (André, 1946) described from a gerbil in Tunisia (Vercammen-Grandjean & André 1967) and differs from the latter by the presence of a 3 - pronged palpal claw vs. 4 - pronged, two pairs of eyes vs. one pair, shorter legs (Ip = 473 – 531 vs. 577 – 613), slightly smaller scutum (PW = 49 – 55 and SD = 29 – 31 vs. 60 – 64 and 34 – 35, respectively), and shorter scutal setae (AL = 10 – 12 and PL = 21 – 24 vs. 19 and 26 – 30, respectively). Cheladonta neda is also similar to C. gouldi Lakshana, 1969 and differs from it by the presence of branched dorsal and lateral palpal tibial setae (fPp = B / b / BbB vs. B / B / NNB), presence of tibiala III, a lesser number of idiosomal setae (DS = 31 – 35 and V = 27 – 31 vs. 40 – 46 and 40, respectively), narrower scutum (AW = 42 – 48 and PW = 49 – 55 vs. 52 – 55 and 68 – 72, respectively), shorter setae (AM = 17 – 23, AL = 10 – 12, PL = 21 – 24, and H = 22 – 27 vs. 25 – 27, 20 – 23, 33 – 36, and 34, respectively), and by shorter legs (Ip = 473 – 531 vs. 632) (Lakshana 1969).	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

8545EB45EC15A00DFF3F8E0EFC4887ED.taxon	discussion	Remarks. According to the original description, D. fulminans is similar to D. alata and differs from it “ by the presence of eyes and nude seta on telofemur of leg I and by longer dorsal setae, shape of trichobothria, greater size of body and scutum ” (Schluger et al. 1961). We confirm the similarity of these species and their difference by the presence of eyes (1 + 1 in D. fulminans and 0 in D. alata) and by the presence of long nude seta on telofemur of leg I in D. fulminans (absent in D. alata). Sensilla (trichobothria) bear a few barbs in D. fulminans and are densely covered with spikes in D. alata. Morphometric differences between these two species are as follows. Size of scutum: AW = 35 – 45, PW = 59 – 71, SB = 28 – 33, and PSB = 19 – 24 in D. fulminans vs. 29 – 35, 51 – 58, 24 – 26, and 17 – 19 in D. alata, respectively; lengths of setae: H = 52 – 60, D max = 45 – 60, and V max = 38 – 50 in D. fulminans vs. 40 – 42, 39 – 43, and 31 – 36 in D. alata, respectively. Doloisia fulminans also has a lower number of idiosomal setae (fD = 4 H- 6 - 8 - 6 - 6 - 3 and NDV = 67 – 72 vs. 4 H- 10 - 8 - 6 - 6 - 2 and 75 – 80 in D. alata).	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

8545EB45EC2EA036FF3F8FF7FC2E84B1.taxon	discussion	Remarks. Doloisia gigantea is similar to D. varmai (Audy and Nadchatram, 1957) (Schluger et al. 1961), from which it differs by the shape of sensillum (with an expanded top bearing 6 long spikes vs. rounded top covered with multiple, but shorter setules), by the presence of 3 setae on coxa II, vs. 4, branched palpal genual seta, vs. nude, wider scutum (AW = 30 – 35 vs. 25 – 26 and SB = 29 – 34 vs. 23 – 25), and longer AM (39 vs. 26 – 29). This species is also similar to D. vercammeni (Audy and Nadchatram, 1957) by the very large size and by the shape of sensilla, but differs in the presence of 3 setae on coxa II, vs. 4, branched palpal genual seta, vs. nude, shorter scutal and idiosomal setae (AL = 18 – 24, PL = 44 – 47, and H = 54, vs. 31 – 34, 66 – 72, and 83, respectively), and lower number of idiosomal setae (NDV = 69 – 70 vs. 82 – 107). Doloisia outoensis was synonymized with D. gigantea by Wen (1984). According the original description of D. outoensis, it has 3 – 4 setae on coxa II and 6 – 8 setae on coxa III (Chen & Hsu 1965); thus, variation of these characters in D. gigantea is obviously wider than in its type series.	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

8545EB45EC2BA03AFF3F8EF2FE278555.taxon	discussion	Remarks. Schoutedenichia alongensis was synonymized with S. centralkwangtunga by Domrow (1962) who examined two of its specimens collected from Suncus murinus in Saigon (currently Ho Chi Minh City) in South Vietnam. He provided measurements of scutum and scutal setae of these specimens. Comparison of our measurements of the S. alongensis type series, measurements of one additional specimen of S. centralkwangtunga from Thailand, and the reference data provided by Mo et al. (1959) and Domrow (1962) shows that these data constitute a continuous range of variability for the most part of characters (Table 9). One exception is the width of scutum (AW, PW, and SB), which is clearly smaller in the type series of S. centralkwangtunga than in other materials. That could be a result of geographic variation or a deformation of the scutum during preparation in the latter set of materials.	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.

This species is similar to M. spicea (Gater, 1932) by the presence of slightly expanded sensilla, but differs by the nude lateral palpal tibial seta (fPp = B / B / BNB vs. B / B / BBB), 7 - segmented legs (fsp = 7.7.7 vs. 7.6.6), longer scutum (SD = 46 – 48 vs. 41 – 42), and longer legs (Ip = 585 – 636 vs. 516 – 534) (Vercammen-Grandjean 1965 a). As Vercammen-Grandjean (1965 a) noted for M. spicea, the presence of slightly expanded sensilla relates this species to the genus Ascoschoengastia from the tribe Schoengastiini. Probably, Kudryashova (2004) did not list M. vitosa in the catalogue of types because of the uncertainty of the taxonomic position of this species.	en	Antonovskaia, Anastasia A., Stekolnikov, Alexandr A.
