AKT. 14 TEEMITES FROM AMAZON BASIN SNYDER 43 



hitherto inchided in this subgenus {Tenuirostritermes) of Hohn- 

 gren. The nasus is long and cylindrical in most species of Subuli- 

 termes^ but this species may be in this subgenus. 



Type locality. — Cachuela Esperanza (Beni River), Bolivia. 



Described from 8 soldiers collected at the type locality with Cor- 

 nitervies {Lahiotenncs) lahralis Holmgren in Mar; h, 1922, by W. M. 

 Mann. 



Type, soldier.— Cat No. 276G0, U.S.N.M. 



NASUTITERMES (TENUIROSTRITERMES) LATICEPHALUS, new species 



Soldier (pi. 3, figs. 7-8). — Head light yellow-brown (straw col- 

 ored) with longitudinal striae (possibly muscles visible due to light 

 color), broad but short — only slightly longer than broad; somewhat 

 pear-shaped, narrowed and slightly constricted anteriorly, broadest 

 at posterior margin which forms nearly a straight line (where 

 slightly emarginate or divided into two lobes) ; two rows of bristles 

 on dorsum of head, one row of 4 bristles anteriorly and the other 

 row of 2 bristles posteriorly ; head also with dense short hairs. 

 Nasus light castaneous-brown, fairly short, slender, with short hairs. 

 ^Mandibles prominent, short, sharp points. 



Antenna yellow-brown, 13 segments, pubescent; third segment 

 slender, clavate, longer than second or fourth; fourth shorter than 

 second ; fifth wider, nearly as long as third ; segments become longer 

 and wider toward apex. 



Pronotum white, anterior margin yellow-broAvn, saddle-shaped; 

 with short hairs. 



Legs white with tinge of yellow, fairly elongate, pubescent. 



Abdomen dirty gray, with tinge of yellow, a row of long bristles 

 on each tergite, also short hairs, many long hairs at end abdomen. 

 Measurements. — 



Length of entire soldier, .3.00-3.20 mm. 



Length of head with nasus, 1.1.5-1.20 mm. 



Length of head without nasus (to anterior), 0.80 mm. 



Length of nasus, 0.40-0.45 mm. 



Length of pronotum, 0.11 mm. 



Length of hind tibia, 0.75-0.78 mm. 



Width of head, 0.70-0.75 mm. 



Width of pronotum, 0.35-0.36 mm. 



This species is placed in the subgenus T enuirostritermes due to 

 the slight constriction of the head, the mandibles, legs, and the fact 

 that in the worker the post-clypeus is twice as Avide as long. The 

 most striking characteristic of this species is its broad head, hence 

 the specific name. 



Type Inenlity. — Covendo. Bolivia.
