PITYOPHTHORUS ZETEKI, new species 
PLATE 22, FIGURE 35 
Female.—Reddish brown; 1.71 mm. long, 2.93 times as long as wide; 
with elytral apex acuminate and declivital interspaces setose. 
Frons flattened from eye to eye on more than a semicircle, feebly 
shining, punctures very fine, moderately close, with fine, long, yellow 
hairs, longer and curved inward at periphery. Eye rather large, 
coarsely faceted, about one-third divided by emargination. Antenna 
(fig. 35) with club 1.24 times as long as wide, 1.44 times as long as 
funicle; first 2 sutures scarcely arcuate, with septa strong but in- 
complete; third suture strongly arcuate, indicated by row of setae. 
Pronotum 1.23 times as long as wide, widest on posterior half, 
posterior outline weakly arcuate, margined, posterior angles rounded; 
sides straight and subparallel on posterior half, feebly narrowed at 
weak lateral constrictions, very broadly rounded in front, with anterior 
margin finely serrate; anterior area with small, low, weak asperities, 
in irregularly concentric arrangement, with rather short, fine hairs, 
inconspicuous except in profile; summit low, with posterior transverse 
impression broad and shallow; median line unmodified, with punctures 
as on rest of disk; sides shining; disk and sides apparently glabrous. 
Elytra as wide as pronotum, 1.76 times as long as wide, 1.44 times 
as long as pronotum, sides nearly straight and subparallel for more 
than three-fourths of length, then strongly narrowed, with sutural 
region drawn out into a sharp acumination; surface brightly shining, 
with rather coarse, deep, very close punctures forming regular, im- 
pressed striae, first stria more deeply impressed; interspaces rather 
narrow, devoid of setae except near declivity; sides with punctures 
smaller, striae not entirely regular and not impressed except on pos- 
terior third. Declivity rather steeply arched; suture elevated through- 
out, strongly extended at apex, finely punctured and with moderately 
small granules; first stria strongly impressed, all striae strongly punc- 
tured, all interspaces punctured and all but second more or less granu- 
late, with first and alternate interspaces more strongly granulate; 
lateral elevations not so high as suture; all interspaces bearing 
moderately short, stout, erect, yellowish setae. 
Male—Slightly shorter and stouter than female, 2.77 times as long 
as wide; frons convex, transversely impressed below, moderately 
coarsely punctured, with hairs sparse, short, and fine; elytral declivity 
more strongly sculptured, with much coarser granules, especially on 
third interspace; declivital hairs coarser than in female. 
Type locality —Trinidad River, Panama.
