Morphology and Anatomy:

Haliplectus spp. can be separated into two groups characterized by the shape of the basal bulb of the esophagus:

Genus characterized by:

• annulated cuticle with annules smooth or with longitudinal fine striae

• pores along the body

•  absence of subcephalic, ocelli, cervical sensilla, deirids and somatic setae

• amphidial fovea ucircul;ar, located posterior to cephalic region,

• stoma long and narrow stoma, with or without teeth,

• procorpus cylindrical or twith small median bulb, isthmus short, large and larger muscular posterior bulb with or without transverse striation and with well-developed cuticular lining,   tail similar between sexes, conoid or subcylindrical with rounded terminus. Three caudal glands present or absent, spinneret present of absence.

	Female: didelphic, amphidelphic or monodelphic- prodelphic ovaries reflexed, Male:  diorchic, testes outhstretched spicules arcuate, gubernaculum present, precloacal papilliform sensilla present or absent, supplements and postcloacal sensilla absent, Ref: Holovachov, 2014; Shahina et al.,, 2014
