Key to the males of Helicopsychidae View in CoL from Barro Colorado Island

1 Postantennal setal warts strongly enlarged and larger than the cephalic setal warts in

lateral view (fig. 42A in Johanson 2002); cephalic setal warts anteriorly swollen and separate from head capsule (fig. 42A in Johanson 2002) ................ H. tuxtlensis View in CoL Bueno ­ Postantennal setal warts much smaller than the cephalic setal warts; cephalic setal warts not swollen anteriorly and fused with head capsule along its length .................. 2

2 Xth tergum with row of megasetae starting proximally on the segment; gonocoxite strongly sickle­shaped; basimesal lobe tuboid; phallus uniformly curving ventrally along its length ................................................................................. H. vergelana Ross View in CoL

­ Xth tergum with megasetae present only on mid and distal part of the segment ( Figs 5 View FIGURES 1 ­ 8 , 13 View FIGURES 9 ­ 16 ); gonocoxite shape different ( Figs. 4 View FIGURES 1 ­ 8 , 12 View FIGURES 9 ­ 16 ); basimesal lobe cone­shaped ( Figs 6 View FIGURES 1 ­ 8 , 14 View FIGURES 9 ­ 16 ); phallus strongly curving ventrally at midlength ( Figs 7 View FIGURES 1 ­ 8 , 15 View FIGURES 9 ­ 16 ) ....................................... 3

3 Gonocoxite sharply incised toward basimesal lobe ( Fig. 12 View FIGURES 9 ­ 16 ); gonocoxite with basimesal lobe very long ( Fig. 12 View FIGURES 9 ­ 16 ); gonocoxite sharply triangular ( Fig. 12 View FIGURES 9 ­ 16 ); posterior margin of gonocoxite with prominent processes ( Fig. 12 View FIGURES 9 ­ 16 ) ................................. H. fridae sp.n.

­ Gonocoxite widely incised toward basimesal lobe ( Fig. 4 View FIGURES 1 ­ 8 ); posterior margin of gonocoxite with row of prominent processes ( Fig. 4 View FIGURES 1 ­ 8 ) or processes are lacking ................. 4

4 Gonocoxite ( Fig. 4 View FIGURES 1 ­ 8 ) parallelogram­shaped, and with row of processes at posteroventral margin; basimesal lobe ( Fig. 6 View FIGURES 1 ­ 8 ) with smooth lateral and median margins, and bearing about three stout megasetae .................................................................... H. woldai sp.n.

­ Gonocoxite widens slightly distally; posteroventral margin without processes; basimesal lobe with irregular median and lateral margins associated with numerous setae and no stout megasetae ................................................................................. H. incisa Ross View in CoL
