Abstract
Oscheius onirici sp. n. (Nematoda: Rhabditidae) was isolated from a karst cave soil of Central Italy. Molecular and morphological analyses were performed. Total DNA was extracted from individual nematodes and the mitochondrial COI, the ITS containing region, the D2-D3 expansion domains of the 28S rRNA gene and the 18S rRNA gene were amplified and sequenced. BLAST search at NCBI by using all molecular markers revealed that this taxon is similar to Oscheius species. Phylogenetic trees of ITS, 28S and 18S rDNA revealed that O. onirici sp. n. belongs to Dolichura-group. Oscheius onirici sp. n. is characterized by small body size and stoma rhabditoid type. Female reproductive system is amphidelphic. Males are rare with peloderan bursa, spicules slender and small, nine pairs of papillae of different lengths, arranged in a 1+1+1/3+3 pattern. Entomopathogenicity bioassay revealed that this nematode is capable of infecting larvae of Galleria mellonella and Tenebrio molitor.Entities:
