Shilova, 1961
Body
Large larvae up to 11 mm long. Living larvae red. No of ventral tubules on the 11th segment. Procercus and anal tubules present (Wiederholm, 1983; Moller Pillot, 1984a).
Head
The head is very broad. Anterior margin of frontal apotome sometimes with a subapical pit. Labral sclerite 1 absent and sclerite 2 is present.
Antenna
The antenna consists of 5 segments. The blade is shorter than the flagellum. Lauterborn organs distally on the second segment.
Mentum
The mentum has 4 small median teeth and 6 pairs of lateral teeth Lip aren mentum close up. The ventromental plates are about 2x as wide as the mentum Lip aren mentum.
Labrum
SI is plumose on both sides and labral lamellae form a single plate with numerous distal teeth. The pecten epipharyngis is smooth, subdivides into 3 parts with apical teeth. The premandible has 5 teeth.
Mandible
The mandible with a pale dorsal tooth, apical tooth dark and 3 inner teeth, The pecten mandibularis is present and seta interna with 4 toothed and plumose branches. The dorsal surface with a distinct hump.
Differential characteristics
The very broad ventromental plates which are twice as broad as the mentum are distinctive for the genus Lipiniella Lip aren mentum.
L. araenicola differs from L. moderata by the absense of ventral tubules on the 11th segment.
