- Leprotintinnus simplex Schmidt (ref. ID; 3596, 3597)
Descriptions
Lorica tubular, 5.3 oral diameters in length; shaft gradually tapering to the opening aboral end without an aboral expansion; wall usually having no spiral structure. (ref. ID; 3596)
Comments
The species differs from L. pellucidus (Cleve) in the lack of a flaring aboral region and from L. simplex Schmidt in the presence of a posterior constriction. (ref. ID; 3596)
Measurements
Length 208; oral diameter 39; aboral diameter 23 um. (ref. ID; 3596)
Leprotintinnus nordqvisti (Brandt, 1906) (ref. ID; 4600) reported year? (ref. ID; 3596), (Brandt) Kofoid & Campbell (ref. ID; 3597)
Descriptions
Lorica consisting of a tubular shaft and an inverted funnel-shaped aboral flare, 4.3-10.5 oral diameters in length; oral rim irregular, usually slightly flaring (80-85 degrees); shaft more or less tapering (15 degrees), expanding near the posterior region to form a distinct aboral conical flare (50-110 degrees); aboral aperture large, 1.2-2.3 oral diameters; aboral margin very ragged; wall showing a faint spiral structure, made of rather scare particles aggregated more thickly on the surface of the aboral flare than on that of the shaft. (ref. ID; 3597)
Comments
The species differs from the other species of Leprotintinnus in having a conspicuous great aboral flare. (ref. ID; 3597)
Measurements
Length 245 (150-352); oral diameter 35 (30-38); aboral diameter 61 (48-80) um. (ref. ID; 3597)

Descriptions
Lorica elongate, 4-8 oral diameters in length; oral rim usually smooth, aboral one rough; shaft slightly conical (1.5-3.0 degrees), constricted at a point little above the posterior end, its smallest transdiameter 0.43-0.64 oral diameter; aboral end flaring (43-97 degrees) with an aboral aperture of 0.7-1.0 oral diameter; wall thin, with or without spiral turns, foreign particles scattered on the surface, generally very sparse, but sometimes rich near the suboral border. (ref. ID; 3596)
Lorica elongate, tubular, 5.5 oral diameters in length; both apertural rims irregular; shaft slightly conical (2-3 degrees) towards the aboral end, constricted a little above the posterior end; aboral end flaring, 0.85 of the oral diameter in aboral diameter; wall thin, with a sparse agglomeration, numerous spiral turns usually appearing in the anterior part. (ref. ID; 3607)
Comments
In some specimens the shaft is more or less bent. The aboral flaring part is variable in size and form, and a number of vertical striae are often running on it. The agglutinated material is exceedingly changeable in amount in individuals and especially crowded in the suboral region. In this specimens the spiral structure is generally inconspicuous or invisible. The species differs from L. bottnicus (Nordqvist) in having an inverted funnel-shaped aboral region and from L. nordqvisti (Brandt) in the smaller size of the flaring aboral part and the absence of a flaring oral rim. (ref. ID; 3596)
Differs from Leprotintinnus bottnicus (Nordqvist) in more widened aboral region and from L. simplex Schmidt in having posterior constriction. (ref. ID; 3607)
Measurements
Length 223 (156-288); oral diameter 38 (33-42); aboral diameter 32 (25-35) um. (ref. ID; 3596)
Length 220; oral diameter 40 um. (ref. ID; 3607)
Descriptions
Lorica tubular, 5.8 oral diameter in length, gradually tapering (2 degrees) to the aboral end without a flare or a constriction; sides more or less curved; aboral diameter 0.86 oral diameter; wall comparatively thin, with sparse foreign particles laid spirally on the surface. (ref. ID; 3597)
Comments
The species differs from L. neriticus (Campbell) in being smaller in dimensions, from L. nordqvisti (Brandt) in bearing no aboral flare, and from L. pellucidus (Cleve) in the absence of a posterior constriction. (ref. ID; 3597)
Measurements
Length 205; oral diameter 38 um. (ref. ID; 3597)
