Neotrombicula elegans Schluger, 1966

Material examined. Location A: 24 larvae from Pellorneum ruficeps ( Passeriformes : Pellorneidae ), 1 February 2010; 1 larva from Larvivora sibilans ( Passeriformes : Muscicapidae ), 4 February 2010; larva from Pellorneum ruficeps ; 4 February 2010; 2 larvae from Turdus dissimilis ( Passeriformes : Turdidae ), 4 February 2010.

Distribution and hosts. N. elegans infests small rodents Apodemus agrarius , Apodemus flavicollis (Melchior) , Apodemus sylvaticus (Linnaeus) ( Rodentia : Muridae ), Myodes glareolus Schreber , and Microtus arvalis (Pallas) ( Rodentia : Critedidae) in Ukraine ( Kudryashova 1998). Larvae found in Slovakia were isolated from soil samples ( Kalúz & Vrabec 2014). We found N. elegans in Vietnam for the first time. Pellorneum ruficeps , Larvivora sibilans and Turdus dissimilis are new hosts for this chigger.

Remarks. Chiggers of this species from Vietnam are identical with N. elegans from Ukraine and Slovakia.
