THE COCKROACH GENUS CALOLAMPRA OF 
AUSTRALIA WITH DESCRIPTIONS OF 
NEW SPECIES (BLABERIDAE) 
By Louis M. Roth 1 and Karl Princis 2 
Princis (1963) listed 23 species of Calolampra, thirteen of them 
from Australia and the others from Africa, India, Burma, China, 
Sarawak and the Philippines. Calolampra simlansis from the Hima- 
layas was described by Baijal and Kapoor (1966). Recently, the 
African species were placed in a new genus Pseudocalolampra (Roth 
and Princis, 1971) and Calolampra laevis (Brunner v. W. ) from 
Burma and China was assigned to the new genus Calolamprodes 
(Bey-Bienko, 1969). Of the other species, ‘‘Calolampra” brunneri 
(Brancsik) is a mislabeled Derocalymma cruralis, and “C.” punctosa 
(Walker) belongs to the genus Laxta (Princis, 1967, p. 7 ° 8 )- 
Calolampra truncata (Brunner v. W.) was listed by Princis (1967, 
p. 627) under the genus Rhabdoblatta. In this paper we describe 
26 species of Australian Calolampra , of which 12 are new. Five 
species, C. gracilis (Brunner v. W.), C. atomifera (Walker), C. 
notabilis (Walker), C. signatura (Walker), and C. propria 
(Walker) have been considered to be synonyms of C. irrorata 
(Fabr. ) (Princis, 1963). Of these, propria is a synonym of C. 
atomifera (Walker) ; the other 4, we believe, are valid species. 
The genitalia of Calolampra consist of 3 major phallomeres 
(Fig. 1). An L2d (dorsal sclerite of the second left phallomere) 
is apparently absent. The prepuce is covered with microtrichia, 
curves upward and is fused to the L2vm. When well developed the 
prepuce is cup-shaped and with L2vm as a handle looks like a ladle; 
rarely is the prepuce unmodified (e.g. Fig. 82). Li (first sclerite 
of left phallomere) and R2 (hooked sclerite of the right phallomere) 
is well developed and lacks a subapical incision. The hypandrium 
(subgenital plate) is symmetrical and bears 2 small equal sized 
styli. All photographs of genitalia, supra-anal plate, and hypandrium 
are from specimens treated with 10% KOH, dehydrated, and 
mounted in Permount. Supra-anal plates were mounted dorsal sur- 
face upward and subgenital plates ventral side uppermost. One or
