Glaubrecht& T. von Rintelen,  15 Aug.1999.   Diagnosis. –Carapace flat, spotted in life, dorsal surfaces smooth; cervical groove shallow, narrow; H-shaped central depression pronounced. Epigastric and postorbital cristae continuous, sharp, subparallel to frontal margin; outer edge of cristae almost reaching anterolateral margin, stopping just before base of first epibranchial tooth. Front with slight depression, entire; frontal median triangle distinct, complete, ventral sides recessed. External orbital angle broadly triangular, outer margin almost straight, about 2 times length of inner margin, first and second epibranchial teeth distinctly triangular. Posterolateral regions lined with oblique striae. Suture between thoracic sternites 2 and 3 almost complete, gently concave towards buccal cavity to almost straight. Palm of chelipeds inflated, fingers shorter then palm, pollex and dactylus pigmented black throughout half the length towards tip. Ambulatory legs relatively long, second pair longest. Dorsal margin of merus smooth, without distinct subterminal spine. Male abdomen reaching imaginary line joining anterior edges of cheliped bases, T-shaped, segment 6 distinctly longer than segment 7; lateral margins of segment 7 gently concave; lateral margins of segment 6 subparallel, gently sinuous. G1 slender, relatively straight, directed upwards, outer margin almost straight, proximal part not clefted; distal part tapering. G2 with well developed distal segment, about 0.6 times length of basal segment.    Distribution. –Lake Matano, South Sulawesi.   Remarks. –  Parathelphusa pantherinawas first described by Schenkel (1902)from seven malespecimens from Lake Matano. In his paper, Schenkel (1902)did not specify a holotype. Bott (1970c)in his monograph, designated a male specimen 36.0 by 28.0 mm as the lectotype. He also noted that together with the same lot (NMB 21a) as the lectotype, there was also a paralectotypefemale. This second bit of data is confusing. Listed in the Basel Museum catalogues under NMB 21a are five malespecimens of  Parathelphusa pantherina, and a physical check by the first author at NMB verified this. According to the catalogue cards, of these five males, one specimenwas the one selected by Bott (1970c)as the lectotypeand was subsequently relabelled NMB 21b. The rest are therefore paralectotypes. However, for some some inexplicable reason, this lectotypemale is now dried while the rest of the specimens are still in alcohol. Of all the species of  Parathelphusafound in Sulawesi,  P. pantherinais the only one which is as distinctly spotted. Dark-red rosettes extend from the carapace to the ambulatory legs, and this pattern is even discernible in long preserved specimens. This character, along with its flat carapace and distinctive slender, relatively straight G1 easily differentiates it from all its congeners in Sulawesi.
