Neoternies in the media joining the radius ^/s of the length of the wing from 

 the base, and also the media is not as strongly chitinized as the radius. How- 

 ever, it seems to be closer to Neotermes than to any other subgenus. Kalo- 

 termes, s. str. and Neotermes are so close that it is doubtful whether there are 

 any distinct characters for separating the two. 



Soldier: 



Head light brownish yellow, darker in front; Y-suture visible as a light 

 line; head rectangular, sides nearly parallel; clothed with scattered short bristles. 



Antennae with 13 — 15 segments; if with 15 segments, the 3d is smaller 

 than the 2d and is equal to the 4th; if with 13 segments, the 3d is equal to 

 the second and is smaller than the 4th. 



Eyes small, slightly pigmented. The ocelli are barely visible above 

 the eyes. 



Labrum triangular. Mandibles are slender and rather long. 



Front margin of the pronotum is emarginate, the sides are straight and 

 parallel; hind margin slightly emarginate. 



In three of the four specimens there are short wing buds on the meso- 

 and metanota. 



The femur of the hind legs is somewhat enlarged, but not more so than 

 in most species of Neotermes. 



Measurements: 



Total length: 9,0—9,5 mm. 

 Length of head: 4,02—4,20 mm. 

 Width of head: 1,75 mm. 

 Length of antennae: 1,75 mm. 

 Length of pronotum: 0,93 — 0,97 mm. 

 Width of pronotum: 1,63 mm. 

 Length of hind tibia: 1,13 mm. 

 Length of left mandible: 1,67 mm. 



Comparison with other species: 



The dentation of the mandibles seems to differ from that of K. brouni 

 Frog, and K. pacificus Banks. 



Type locality: Juan Fernandez Islands, Masatierra (K. Backstrom). 

 In old stumps of trees, lower forest region. 

 Holotype: Winged Imago. 

 Morphotype: Soldier. 



The description is based upon i mature winged imago, 2 white winged 

 imagos, 4 soldiers and several nymphs. The holotype, and morphotype have 

 been deposited in the Naturhistoriska Riksmuseet, Stockholm. Paratypes are 

 deposited in the American Museum of Natural History.
