159. Lamyctes zelandicus sp. nov. 



Type.— M. C. Z. 1,896. Paratypes.— 2,035. New Zealand: 

 Wellington, Tarawera Lake, Naiwa (W. M. Wheeler). 



General color of dorsum brown of slightly reddish cast; legs and antennae 

 fulvous. 



Head subcordate, anteriorly mesally emarginate, a sulcus extending from 

 emargination caudad to frontal suture. 



Prosternal teeth distinct, acute, 2 + 2, the median sinus wide v-shaped, 

 shallow. 



Coxal pores very small, 2, 2, 2, 2 (1). 



Basal spines of female gonopods 2 + 2. 



Posterior angles of none of the dorsal plates at all produced, caudal margins 

 straight. 



Tarsal joints of anal legs abruptly considerably more slender than the meta- 

 tarsus; first tarsal joint six times as long as thick. 



Length (female type, not quite fully mature), 4.8 mm. 



This species difPers clearly from L. fulvicornis in the much more 

 slender tarsal joints of the anal legs and in the shorter antennae com- 

 posed of only twenty-two articles. It is obviously smaller than the 

 Tasmanian species above described and is unlike L. africana in having 

 the accessory claws of the legs very small. 



160. Lamyctes navaianus, sp. nov. 



Type.— M. C. Z. 2,133. Paratypes.— 2,134. Fijis. Navai 

 (W. M. Mann). 



Very similar to L. munianus but a smaller, less robust species. The color 

 a Uttle lighter brown without distinct darker markings excepting about eyes 

 where black is pronounced. Antennae very short, composed of fewer articles, 

 normally twenty-three or twenty-five. Prosternal teeth small, 2 + 2, the 

 median incision somewhat less acute than in munianus. Caudal margins of 

 ninth, eleventh, and thirteenth dorsal plates wholly straight. Tarsi as usual 

 as are also the tibial spurs. Coxal pores 2, 2, 2, 2. Basal spines of female 

 gonopods short, acute 2+2. Gonopods of male short, straight, triarticulate, 

 ending in a short seta. Anal legs longer and more slender than in L. fulvi- 

 cornis, especially the tarsal joints. Accessory claws short. 



Length of male, 5 mm.; of female, 4.5 mm.
