Castoraeschna tepuica DeMarmels. 1989

Material. 1♂ (reared from last instar larva); 1♂, additional last instar exuviae; Unturan .

Remarks. Several additional larvae, some in the last instar, were found in an about 1 m broad black water creek in the forest, where they clung to roots under the overhanging bank. The bottom of the creek is stony with no sand and but little detritus. The male larva was described by DeMar. mels (1990). Female larvae are still unknown. A single ultimate instar larva of this sex was also caught at Unturan, but was lost just before emergence of the adult. Therefore, any information about the length of the gonapophyses can not be given. However, the larva was very similar in ove· raIl appearance to male specimens. Adults were not observed.
