Eyes purplish, not quite round, not very prominent, separated from the 
lateral margins of head by a distance less than an eye diameter. Ocelli 
separated from eyes by a distance less than their small diameter. 
Labrum yellow-brown, semi-tongue shaped. 
Post-clypeus yellow-brown, much broader than long. 
Pronotum about same color as head, smooth, shining, subcordate, not as 
wide as head, emarginate both anteriorly and posteriorly, raised up anteriorly, 
with long hairs. 
Legs with femora greyish-brown, tibiae and tarsi yellowish. 
Wings smaller than in flavipes and in the forewing the median vein is 
intermediate between subcosta and cubitus, whereas in lucifugus it is nearer 
to the cubitus. 
Wing scale longer than pronotum, being 0.80 mm. in length. 
Abdomen with tergites slightly lighter colored (more grey) than head, with 
long hairs; cerci three segmented; styli present in the male.

From descriptions, R. chinensis is a smaller, lighter colored species than 
R. speratus Kolbe; the head is more hairy in chinensis and the teeth of the 
mandibles slightly different (Fig. 1); the ocelli are nearer to the eyes; the pro- 
notum is not yellow. In the forewing the median vein is more intermediate 
between the subcosta and cubitus than in speratus. Winged adults of 
chinensis were compared with winged adults of Reticulitermes lucifugus Rossi 
from Talheiro, Maderia; of R. flavipes Kollar from the eastern United States;
