Steinernema keralense n. sp., a new entomopathogenic nematode (Nematoda: Steinernematidae) from India

Popis výsledku v původním jazyce

In this study, morphological and molecular features were used to identify a new Steinernema sp. from Kerala, India. Morphological and molecular features provide evidence for placing the new species into the longicaudum clade. The new species is characterized by the following morphological features: infective juveniles with a body length of 1067 mu m (914-1268 mu m), a distance from the anterior end to excretory pore of 82 mu m (73-92 mu m), a distance from anterior end to nerve ring of 105 mu m (91-118 mu m). The distinguishing feature of the infective juveniles of S. keralense n. sp. is the presence of seven ridges in the mid-body region, while all other species classified within the logicaudum clade to date are characterized by eight ridges. The first-generation males are characterised by 25 genital papillae, very short spicules, with a length of 68 mu m (60-72 mu m), and the SW% ratio is 136 (114-169). The new species is further characterized by sequences of the internal transcribed spacer and partial 28S regions of the ribosomal DNA. Phylogenetic analyses show that S. keralense n. sp. is closely related to species within the longicaudum clade.
