Four new species of free-living marine nematode from the sea areas of China
摘要
Abstract
Two new species of genus
Diplopeltoides
Gerlach
1962
Gerlach
1962
and two new species of genus
Minolaimus
Vitiello
1970
Vitiello
1970
were described based on recently collected specimens from marine sediments of the South China Sea and the East China Sea
respectively.
Diplopeltoides conoicaudatus
sp. nov. is characterized by annulated cuticle; tiny terminal buccal cavity; short cephalic setae about 2-μm long; loop-shaped amphideal fovea without sclerotized plate; slender and arcuate spicules; triangular gubernaculum possessing a small dorso-caudal apophysis; female with two opposed and reflexed ovaries.
Diplopeltoides longifoveatus
sp. nov. is characterized by its papilliform cephalic sensilla; long and narrow amphideal fovea with fine transverse striations; inverse S-shaped spicules with a dorsally bent manubrium; gubernaculum with dorso-caudal apophysis; cylindrical tail with round terminal end.
Minolaimus multisupplementatus
sp. nov. is characterized by cuticle with lateral differentiation of three longitudinal rows of large dots
spiral amphideal fovea with seven turns
pharynx cylindrical without posterior bulb
spicules arcuated with central lamella
gubernaculum arcuate and parallel to spicule
without dorso-caudal apophysis
a papilliform and 29 cup-shaped precloacal supplement; tail conical with long flagelliform portion.
Minolaimus apicalis
sp. nov. is characterized by cuticle with lateral differentiation of three longitudinal rows of larger dots from the middle of pharynx to the conical portion of tail and a longitudinal row of pores in the pharyngeal region and precloacal region; spiral amphidial fovea with four turns and close to anterior end; pharynx cylindrical with oval posterior bulb
spicules arcuated and proximal end bent dorsally
gubernaculum with a broad curved dorsal apophysis; two sucked-like and six cup-shaped cuticularized precloacal supplements; tail conico-cylindrical with slightly enlarged tip. Updated keys to species of
Diplopeltoides
and
Minolaimus
were provided.
