TYPE LOCALITY AND TYPE REPOSITORY. Thailand, Mae Hong Son Province, Ban Huai Po , 1600–1700 m a. s. l. ; FKCP, NMPC.

TYPE MATERIAL EXAMINED ( FKCP, NMPC). Thailand, Mae Hong Son Province (18.72°N 96.87°E), Ban Huai Po, 10. V.1991, leg. J. Farkač, 3♂ (holotype, paratypes Nos. 1–2), 4♀ (paratypes Nos. 5–8), 4♀ juvs. (paratypes Nos. 9–12), 4juvs. before first ecdysis (paratypes Nos. 13–16), 2juvs. after first ecdysis (paratypes Nos. 17–18), 9juvs. after second ecdysis (paratypes Nos. 19–27), 2juvs. after third ecdysis (paratypes Nos. 28–29), rearing F. Kovařík .

OTHER MATERIAL EXAMINED ( FKCP). Thailand, Thung Pong , near to Chiang Mai, X.2004, 1♀, leg . V. Fura ,

DIAGNOSIS (♂ ♀). Total length 25–33 mm in males, 27–37 mm in females. Base color uniformly reddish black. Pectine teeth number 6–7 in males and 5–6 in females, fulcra absent. Pectines with 2 marginal and 1–3 middle lamellae. Patella of pedipalp with 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 9 ventral trichobothria. Chela of pedipalp with 4 V series trichobothria located on ventral surface. Chelal trichobothrium Eb 3 located in proximal half of manus between trichobothria Dt and Db. Fingers of pedipalps almost straight in both sexes; male has apophysis on movable finger developed. Chela length to width ratio 2.7–3.1 in male and 2.4–2.5 in female. Pedipalp movable finger with 25–30 IAD, ca. 55 MD which create 10 straight rows in a line and there are also 5 ID and 11–12 OD present. Metasoma I with 10 carinae and metasoma II–IV with 8 carinae. Telson bulbous, sparsely granulate, length to depth ratio 2.8 in both sexes; annular ring present.

COMMENTS. Lourenço & Pham (2015a) described Scorpiops (Vietscorpiops) dentidactylus , diagnosed by a unique character, an internal apophysis on the pedipalp movable finger (fig. 3a in Lourenço & Pham, 2015a). Because the holotype male was the only known specimen, the authors cited this character without knowing that it is present only in the male. Kovařík (1993) described Scorpiops farkaci according to 21 specimens which represented males, females and juveniles, and the apophysis on the pedipalp movable finger is presented only in males ( Fig. 790 ). It is evident that this character represents an atypical sexual dimorphism. Lourenço & Pham (2015a) did not cite any characters that could decisively differentiate S. dentidactylus from S. farkaci . The only difference is that the types of S. farkaci have base color uniformly reddish black, while the male holotype of V. dentidactylus has base color uniformly reddish brown. A likely explanation for the color difference is fading of the latter after long storage in alcohol, since 1939 (cf. Lowe, 2018: 64–65). Otherwise, the published characters of V. dentidactylus and the holotype of S. farkaci match each other precisely. The inevitable conclusion is that Scorpiops (Vietscorpiops) dentidactylus Lourenço & Pham, 2015 is a junior synonym of Scorpiops farkaci Kovařík, 1993 . In addition, below is described another related species Scorpiops thailandus sp. n. which has the same sexual dimorphism, but with smaller apophysis ( Figs. 790 versus 791).
