This genus was thus diagnosed : “ Differs from Pinarolestes Sharpe in its 
less compressed bill, longer wing and stronger feet, and different wing 
formation ; the fifth primary longest and the second equal to the tenth.” 
Ramsay in 1888 recorded : “I cannot agree with Mr. Sharpe in including 
Collyriocincla rufigaster, C. pcirvulus, and C. macrorhynchus in his genus 
Pinarolestes, as he founds this new genus on Myiolestes vitiensis Auct. ; a bird 
differing greatly even in habits and nidification from the true Collyriocinclse, 
to which the above named species belong.” 
This group consists of small Colluricincloid birds with the bill longer 
than the head, laterally compressed with a sharp hooked tip and the nostrils 
hidden by appressed bristles and the rictal bristles prominent. The wing 
formula differs appreciably, the first primary short, about equal to half the 
length of the third, the second intermediate and about equal to the tenth 
primary and the secondaries ; the third primary is equal to the seventh and 
the fourth, fifth and sixth are little longer, the fifth being the longest. The 
tail is long and square as usual. The legs are rather short and stout, the 
front of the tarsus bearing five pronounced scutes, the hind part bilaminate ; 
the hind-claw is longest, but the hind-toe and claw is shorter than the middle 
toe and claw ; the outer toe longer than the inner toe, and the inner toe and 
claw equal to the middle toe alone. 
This is the New Guinea group confused by recent writers with Pinarolestes .
