Steinernema pwaniense Puža, Nermut, Mrácek, Gengler &

Haukeland, 2016

Summary: Steinernema pwaniense, belonging to the glaseri-group, is described
from Tanzania. The infective juveniles are characterised by a body
length of 978 (808-1131) μm, distance from anterior end to excretory
pore of 86 (80-95) μm and a tail length of 87 (75-95) μm. The ratios
a, c and E% are substantially lower than those of all other African
glaseri-group members. The first generation male can be distinguished
by a large spicule length of 92 (80-97) μm and by the absence of
the caudal mucron, while the second generation male possesses a
short spine-like mucron. First generation females have a peg-like tail
tip bearing three spine-like projections. Second generation females
can be recognised by a slightly protruding vulva and well developed
postanal swelling. The species is further characterised by sequences of
the ITS (KT358811) and partial 28S regions of the ribosomal DNA
(KT358813). Phylogenetic analyses show that S. pwaniense forms a strongly
supported monophyletic clade with two other East African
species, S. ethiopiense and S. karii. 

 Emended ending from the incorrect -ensis. The specific epithet is derived
from the regional name Pwani, a Swahili word meaning coast or coastal.
