Heterometrus Spinifer
DIAGNOSIS. Adults 100–135 mm long. Base color of adults uniformly black, only manus and telson may be reddish brown. In juveniles base color reddish brown, telson may be yellow. Pectinal teeth number 15–19 in both sexes. Sexual dimorphism in proportions of pedipalps not noticeable. Chela slightly lobiform, its adult length to width ratio 2.4–2.6 in both sexes. Much of manus smooth, with smooth carinae forming irregular reticulation. Patella of pedipalp with pronounced internal
tubercle. Carapace with disc smooth and margins granulate. Telson hirsute, elongate, vesicle longer than aculeus.
COMMENTS. Couzijn (1981: 91) stated that the holotype could not be found and had apparently been destroyed during WW2. For that reason he designated a neotype. However, the holotype was not destroyed, it is preserved at ZMHB and I have been able to borrow it for study. It is an immature male. In accordance with ICZN Article 75.8, Couzijn’s neotype designation is invalid. Since it is impossible to ascertain that the BMNH specimens of Palamnaeus oatesii Pocock, 1900 really are syntypes, I do not designate a lectotype. The specimens were apparently first kept dry and then transferred to alcohol with the determination label Palamnaeus oatesii, but without any other data. No other specimens so labeled could found at BMNH. The distribution of this species can be verified only for Malaysia and southern Thailand. Other records are misidentifications that concern primarily H. cimrmani sp. n. and H. petersii.

Heterometrus Longimanus
DIAGNOSIS. Adults 90–140 mm long. Base color of adults uniformly black, only manus and telson may be reddish brown. Pectinal teeth number 12–18 in both sexes. Male with chela, femur and patella of pedipalp narrower and longer than in female. Male fingers of pedipalp very long. Fixed fingers longer or at least as long as manus of pedpalp. Chela not lobiform in male, slightly lobiform in female, its length to width ratio 3.3– 4.4 in male, ca. 2.4. in female. Much of manus smooth,
sparsely tuberculate. Patella of pedipalp with pronounced internal tubercle. Carapace usually with disc smooth and margins granulate, but sometimes entire surface granulate. Telson hirsute, elongate, vesicle as long as or longer than aculeus.
COMMENTS. This species is known under a number of older names and as many as eight subspecies. I have
studied the paratypes of H. l. belitungensis Couzijn, 1981 and specimens from nearly the entire area of known distribution of the species, and have not found any morphological differences indicating the existence of any subspecies. I have examined also CASC specimens from the type locality of H. l. tarawakanensis Couzijn, 1981 and have not found them to differ in any way from the nominotypical subspecies. However, I have not studied the types of all the subspecies.
