Diagnosis. — Shell wall and basis forming distinct wedge shape in side view; rostrum and 
basis elongated along host axis, carina not elongated along host axis, carina and carino-latera near¬ 
ly vertical in aspect; latera sloping at an increasing angle toward rostral margin; summits or radii 
even, not disparietal; basis wedge-shaped in side view, widest at carinal margin, tapering evenly to 
rostral end where rostmm comes into contact with host axis. 
Description. — Shell wall conical except for greatly elongated rostrum; parietes, except for 
rostrum, with reddish brown and white longitudinal stripes interrupted by white horizontal lines; 
radii with dark red horizontal lines, summits even; rostmm white, some with very faint red and 
white stripes nearest latera, elongated to a width about the same as or greater than all other wall 
plates combined; basis white, elongated along host axis, not raised or raised only very slightly 
above the axis at extreme rostral end, tapering upward gradually to carina basal margin, then slop¬ 
ing steeply down to host axis again, together with shell wall shape forming a wedge shaped shell. 
Basis and parietes lacking longitudinal tubes. Scutum height slightly greater than width; strong 
articular ridge more than V 2 length tergal margin; basal margin curved, slope toward tergal margin 
steeper in larger specimens, milder in smaller specimens; adductor muscle pit shallow; depressor 
muscle pit shallow to moderately deep; apex acute, growth ridges visible apex interior; tergal and 
occludent margins fairly straight; interior surface textured near apex and articular ridge. Tergum 
width slightly greater than height; apex beaked unless eroded; carinal and basal margins slightly 
convex, scutal margin fairly straight; spur short, wider in older specimens, narrower in younger 
specimen; basiscutal angle very shallow; broad and shallow spur furrow, 6-10 depressor muscle 
crests, faint to high ridges; articular furrow wide; articular ridge prominent; interior surface peb¬ 
bled. Labrum with 2-4 teeth either side of notch; notch triangular; cutting margin with short fine 
setae. Mandible with 5-6 teeth; 2^^ and/or 3^^^ tooth may be bi-dentate; and 2^^^ teeth furthest 
apart, 2nd and 3 rd slightly closer, 3rd, 4*, and 5* very close together; 4*, 5^^, and occasional 6^^ teeth 
small; fine dense setae along superior, inferior, and just below cutting margins. Maxilla cutting 
edge notch may or may not be present, located two large spines in from superior angle; 9-13 large 
spines along cutting margin; medium length fine setae along superior and inferior margins as well 
as below and along cutting margin. 2nd Maxilla small, elongate or egg shaped, bi-lobed; apex, infe-
