THE SOLDIERLESS TERMITES OF AFRICA 



215 



Holotype $ imago, paratype <$ and $ imagos, and workers from type-colony, 

 Kenya: 9 m. from Londiani on Kisumu Road, alt. over 7,000 ft, 19. ii. 1964 

 (R. M. C. Williams Coll. No. RW9) in British Museum (Natural History). 



Other paratype material. Kenya: Kaptagat, 3.^.1952 (W. V. Harris); same 

 data {W. A. Sands) also in BMNH. 



The species has been recorded from the mounds of Cubitermes and Odontotermes 

 only at high altitudes in montane grassland. 



Anenteotermes nanus (Sjostedt) comb. n. 



(Text-figs 571-574 & 589-594; PI- 8, fig. 2) 



Eutermes nanus Sjostedt, 191 1 : 161. LECTOTYPE 9, Democratic Republic of Congo: 

 Mukimbungu (Naturhistoriska Riksmuseum, Stockholm) here designated [examined]. 



Imago. Head capsule (colours probably somewhat faded) brown, not appreciably darker 

 above ocelli ; fontanelle very small oval, flat, slightly paler than head ; medial spot oval, about 

 equal in size to fontanelle, slightly raised on small bump, coloured as head; postclypeus a little 

 paler than head, labrum yellow, frontal marks flat crescents, coloured as head; antennae pale 

 yellow-brown. Pronotum, meso- and metanota pale brown, transverse sutures present; 

 femora and tibiae yellow, tarsi pale yellow. Abdominal tergites pale brown, dorsal stigmata 

 paler, sternites and ventral stigmata very pale brown ; cerci yellow. 



Posterior margin of head capsule more or less evenly rounded; ocelli medium-sized, separated 

 from compound eyes by slightly more than half up to nearly own least diameter; postclypeus 

 moderately inflated, Pcl/W, 0-29-0-32, posterior margin evenly rounded, median suture present, 

 weak in some specimens. Apical teeth of mandibles moderately long, La/Li, 0-67-0-76, Ra/Ri, 

 0-84-1-00; subsidiary marginal tooth of left mandible just clear of molar prominence in surface 

 view, complex ratio, L A /Li.L m , 13-20-15-92; point of first marginal tooth of right mandible 

 distinctly behind line of apical to second marginal, anterior edge of first marginal shorter than 

 that of second, complex ratio, Ri/Ra Rm (note difference from ratio used in worker caste), 

 21-1-23-9. Pilosity of head capsule fairly even, forming a slightly rough pelt with emergent 

 setae, brown.
