Discussion: Nanacarus minutus (Oudemans) has been taken on 

 Megapodius buruensis, Burn Islands; on Koptorthosoma te<miscapa, 

 Java; and on Vesper ugo serotinus, Vesper tilio pipistrellus, and Sorex 

 vulgaris, Germany. This species and Giarciius vitis Perraud are the 

 only two known in this family.

tween the propodosoma and hysterosoma. A propodosomal shield may 

 or may not be present. There is a pair of vertical setae on the propo- 

 dosoma. In other areas the skin has fine striae which are often inter- 

 rupted by scaly areas or by areas strewn with small points or spines. 

 The legs are very short and may or may not have caruncles- or claws. 

 No genital suckers are present.
