Diagnosis. Length, 1.18mm - 1.72mm. This is one of two entirely dark species treated in this paper. It differs from the other, L. vernalis , in its more evenly rounded pronotum with the less prominent basal angle clearly situated outside of a line drawn through the apical angle ( Fig. 25 View Figure 25-26 ). The surface sculpture of the pronotum is very coarse so that it appears dull, and there is no area of different sculpture ( Fig. 28 View Figure 27-32 ). The armature of the internal sac ( Fig. 37 View Figure 34-37 , 42 View Figure 41-45 ) is quite different from that of L. vernalis but is very similar to that of L. parvulus , which it resembles in many other respects as well, differing primarily in L. parvulus having a color pattern and different pronotal sculpture.

Distribution. Southern and central U.S., from Indiana south to Florida and west to Texas.

Discussion. Described from a “...single specimen,

taken by Mr. Schwarz at Columbus, Texas.” ( Casey

1916). I have examined the female holotype in the

USNM, which has the following label data:

“Columbu [?]-8 Texa” [part of the data have been cut away on this label]/”CASEY bequest 1925"/

robustulus Csy. ”/” Lathropus robustulus Csy ”.
