Diagnosis. — Shell wall elongated along host axis, carina about same width as all other wall 
plates combined; rostrum short and not greatly elongated, rostral basal margin about same length 
as latera basal margin; carino-latera near mid-point of shell wall; basis gently sinuous with great¬ 
est depth at mid-point beneath carino-latera, then narrowing in depth toward rostral and carinal 
ends. 
Description. — Shell wall forming a spindle shape along host axis, carina, mid-point of shell 
wall at carino-latera, carino-latera and latera with red and white longitudinal stripes interrupted by 
white lines, rostmm and basis white; carina about same width as all other wall plates combined; 
rostrum wider than only carino-latera; basis highest under carino-latera, then tapering down toward 
carinal and rostral ends. Basis with tubes, secondarily filled. Parietes solid, lacking tubes. Scutum 
height greater than width; apex acute; tergal and occludent margins fairly straight, basal margin 
convex with steep rise up towards articular furrow; articular ridge prominent, length slightly less 
than total height; interior mildly textured; depressor muscle pit small, shallow; adductor muscle pit 
medium sized, moderately deep. Tergum height and width similar; apex acute, mildly beaked; scu- 
tal and carinal margins straight to mildly convex, basal margin slightly convex; spur fiirrow wide; 
spur wide, short; basiscutal angle shallow, obtuse; articular ridge short, about A length scutal mar¬ 
gin; articular furrow narrow; interior surface pebbled to smooth; moderate depressor crests pres¬ 
ent. Labrum with shallow triangular notch; 1-3 teeth either side of notch, teeth well spaced out
