NO. 3567 LABIDOCERA JOLLAE GROUP—FLEMINGER 23 
Coupler in jollae and kolpos consists of shield ventral to urosome; 
right and left portions of shield turned dorsad flanking urosome and 
extending upward as more or less free, curved, lobiform or lamelliform 
processes. In diandra, right and left portions of shield appressed to 
genital segment. Sac in jollae and kolpos remarkably short and 
arising from left side of coupler; separation of coupler and sac poorly 
demarcated; beginning at genital pore, neck extending to left, ventral 
to genital segment, and posterior along left side of coupler before 
expanding into short sac. In diandra, beginning at genital pore, 
neck extending to left side ventral to genital sezment and turning 
posteriad, as in jollae and kolpos, but then extending dorsad and to

right above anal segment; elongated sac appearing over right caudal 
ramus, and extending posteriad before abruptly turning about 180° 
in horizontal plane and extending toward prosome (figs. 6g,h); about 
three-fourths of sac length projecting forward toward right corner of 
TY. 
Flexure of spermatophore sac projecting it away from usual pos- 
teriorly directed attitude occurs in several other species of Labidocera. 
In detruncata, neck leaves coupler middorsal on genital segment, 
broadening into sac and turning horizontally counter-clockwise about 
150°, distal portion of sac extending to right more or less perpendicular 
to longitudinal axis of urosome. In acutifrons, neck bending abruptly 
about 180° under left caudal ramus and sac projecting anteroventrad 
to left of urosome. In minuta, neck extending to left of midventral
