Description 
Angle of thecal edges 180°-210°; angle of thecal 
faces 27°—30°. Corallum robust and dense; one of 
largest specimens (the holotype) measures 42.3 x 
22.5 mm in calicular diameter and 35.6 mm in 
height. GCD:H = 0.92-1.19. Pedicel short (3.3-3.6 
mm) and small (only 1.1-1.2 mm in diameter). 
Thecal faces flat, usually encrusted with calcareous 
epifauna, but glisteny (not granular); well- 
preserved coralla bear thin reddish-brown stripes 
corresponding to the Sl-6. Thecal faces meet in 
sharp, carinate edges, forming irregular spurs, as 
in T. lamellulosum, which result from successive 
downward eversions of the two principal costae 
followed by subsequent retrenchment of the 
calicular edge. Septa hexamerally arranged in 7 
cycles, the seventh only partially complete in the 
holotype (274 septa); septa formula: Sl- 
4>S5>S6>S7. Inner edges of SIM highly sinuous 
(SSI about 4.0), occurring closely parallel to edges 
of Sl-4 from opposing face. Upper edges of SIM
