Cephth. and Abd. only divided by a simple line. Abd. almost cylindrical, 

 rounded posteriorly. Dors, plate much sufflexed on to the ventr. surface. Genital 

 and anal covers close together, only separated by a rim. common to both, 

 the latter reaching the post, margin, and these 2 pairs of covers occupying 

 the whole central part of the ventr. surface from a little behind the insertion 

 of legs 4 backward and touching the reflexed dors, plate on each side. Mdb.

 Ung. mond. 



Canestrini (1891, in: Atti 1st. Veneto, ser. 7 v.2 p. 718) and Banks (1895, in: Tr. 

 Amer. ent. Soc., v. 22 p. 2) state, that this genus is composed of immature creatures, 

 but this is an error. 



2 species. 



Key to the species. 



Hairs on Dors, of Abd. setiform. L. 750 JLI 1. L. murcioides . p. 75 



Hairs on Dors, of Abd. leaf-like. --- L. over 1 mm .... 2. L. paradoxa . . p. 75 



1. L. murcioides (Berl.) 1896 Angelia m., Berlese, A. M. S.. fasc. 78 nr. 7. 



Im. Similar to L. paradoxa, but indentations of Cephth. not quite 

 equal nor quite half-moon shaped. Pectinations on Psstg. org. longer, and 

 hairs on Abd. setiform, not leaf-like. L. 750 ju. 



In moss. Italy; rare. 



2. L. paradoxa (Haller) 1884 Michaelia p., G. Haller in: Arch. Naturg., 0.501. 

 p. 229 1. 16 f. 58. 



Im. Light brown, twice as long as broad. Cephth. each side with 

 2 equal half-moon-shaped indentations, concave outward, occupying its whole 

 lat. edge except tip of Rost. anterior of the 2 bordered by a ridge. Psstg. 

 org. long, setiform, sparsely pectinated on one side. All the hairs except 

 some of those on the legs leaf-like, mostly fusiform or laceolate. Legs 

 short, not reaching post, end of Abd. L. over 1 mm. 



In decaying Vines. Germany. 



*) As the name Michaelia was preoccupied I have renamed Haller's genus in 

 honor of Dr. H. Lohmann. Berlese's gen. Michaelia (Trombidiidae), in: A. M. S., fasc. 16 

 nr. 6 & fasc. 57 nr. 8, was published 29. December 1884. A. D. Michael.
