Photo Gallery- Forensic Nematology

Definition:  Dorylaiminae.  Characterized by the disc-like lip region, expanded much more widely than the head constriction.  Lateral chords with a series of glandular organs, each with a duct extending through the cuticle and forming a single lateral row of pores on either side.  Amphid apertures practically invisible beneath projecting lips.  Anterior fixed ring of guiding sheath relatively high in pharynx.  Oesophagus beginning as an elongate, spindle-shaped swelling around the base of the spear extension, then extending behind and expanding rather suddenly to form the main muscular portion.  Dorsal oesophageal gland placed rather further back than in other Dorylaims; its duct extending a little forward before entering the oesophageal lumen.  Female gonad single or double, reflexed.  Spicules broad, slightly arcuate.  Lateral guiding pieces present.  Supplements consisting of a pre-anal pair and a ventral row.
