This species certainly differs from Pandercetes plumipes of Doleschall from Amboina 

 (Acta Soc. Sci. Indo. Neerland, 1859, p. 53, pi. ill., fig. 9), which it resembles in plumosity, 

 at least in having much shorter legs; for example, judging by Doleschall's figure, the 

 femur of the 2nd leg in plumipes is about twice as long as the carapace (7 : 14), 

 whereas in P. plumosus the femur is only once and a half times the length (6 : 8"6). 

 From P. isopus, Thorell, from Fly River, New Guinea (Ann. Mus. Genova. xvn., 

 pp. 308, etc.), it differs in having the legs much longer as compared to the carapace, 

 the proportion between the 1st leg and the carapace being 29 : 6, whereas in isopus 

 the proportion is 24f : 6. Moreover the leg measurements given by Thorell probably 

 include the trochanter and part of the coxae, so that the difference is no doubt 

 even greater than appears at first sight.

$ Colour: hairy clothing of limbs and carapace a rich ochre or golden yellow; 

 upper side of head and anterior surface of mandibles rubbed smooth ; sternum very 

 scantily clothed, upper side of abdomen much the same colour but rather darker ; 

 lower side darkish brown with four faint pale stripes passing from the epigastric fold 

 to the spinners : integument of carapace and limbs a deep chestnut brown, mandibles, 

 maxillae, labium and sternum black. 



Carapace longer than broad, moderately high, its length equal to that of tibia 

 of the 1st leg and a little less than its protarsus ; less than tibia of 2nd, less than 

 patella and tibia of 3rd, about equal to tarsus and protarsus of 3rd ; its width just 

 equal to protarsus of 4th. Eyes of posterior line straight, the medians smaller than 

 the laterals and a little nearer to each other than either is to the corresponding 

 lateral ; ocular quadrangle a little wider behind than in front ; anterior median eyes 

 separated by a space, which is less than their diameter and nearer to each other than 

 either is to the lateral ; clypeus a little less than the diameter of anterior median eye. 



Mandibles moderately strongly geniculate at the base. 



Legs: long; 2, 1, 4, 3; the 2nd from the base of the femur more than four 

 times as long as the carapace ; 2nd exceeding the 1st by the length of the tarsus 

 and the 3rd by the length of the tarsus and | of the protarsus : 1st leg, femur 

 with 9 or 10 spines above, patella with spines 1, 1, tibia with 2, 2, 2 below, 2 in 

 front and 2 behind; protarsus with 2, 2 below, 2 in front, and 2 behind; 2nd leg spined 

 like the 1st, the femur irregularly ; 3rd leg like the 2nd, 4th leg with only an anterior 

 patellar spine. 



Vulva consisting of a chitinous plate marked with two arched grooves running 

 longitudinally, approaching each other but not meeting in the middle line in front 

 and circumscribing a heart-shaped area which shows a median depression. 



Measurements in millimetres. Total length 34, length of carapace 17, width 15, 

 length of 1st leg 67, of 2nd 72, of 3rd 51, of 4th 55.
