MALES (measurements of 10 specimens):<br />
Length 6.5-9.0 (7.5) mm; width 310-460 (385);<br />
buccal capsule 50-60 (53) long by 23-43 (38)<br />
wide; esophagus 1.04-1.75 (1.61) mm long;<br />
nerve ring 535-740 (655), deirids 210-300<br />
(265), excretory pore 690-920 (800) from anterior<br />
end; spicules 1.16-1.45 (1.33) mm. Dorsal<br />
and lateral lobes of bursa about equal in length;<br />
ventral lobes shorter. Ventral rays apposed,<br />
reaching margin of bursa; externolateral ray divergent,<br />
shorter, almost reaching margin of bursa;<br />
mediolateral and posterolateral rays apposed,<br />
reaching margin of bursa; externodorsal ray arising<br />
close to lateral trunk, not reaching margin of<br />
bursa; dorsal ray long, slender at origin, dividing<br />
at midlength into 2 arcuate branches that reach<br />
margin of bursa; lateral branchlets short, arising<br />
soon after bifurcation, terminating in small ele-<br />
