 were of two species. One was small and narrow, Lipeurus 

 longipes, which has been recorded from several other species 

 of these birds, although nothing is known of its relationships. 

 The second mallophaga, which was of large size, broad in

 has been found on Tinamus robustus and T. tao. The genus 

 as a whole has been recorded from gallinaceous birds and 

 from penguins.

 This strange, flat insect flew off several times, but after each
