bristles may both be present or only one set may occur _ _ 6
5. The antennae are a lot longer than the
proboscis. The 1st flagellar
segment of the antenna is as long as several of the following
segments
combined. Antennae similar for both
sexes but never very hairy (origin Caribbean) _ _Deinocerites spp. Theobald
Antennae are not much longer then the proboscis (Fig. 2). The 1st
flagellar segment is not as long as several of the following

area. Female claws regularly have
teeth. Female palpi are more than
1/2 as long as the
