(pl. cerci): One-segmented, pad-like lobe, paired. Anus positioned between cerci.
(pi., cerci) an appendage (generally paired) near the end of the abdomen, often segmented but sometimes not and often important in insect classification
(pl., cerci) Paired sensory structures on the last or second last metasomal tergite; the cercus is sometimes a setose finger-like projection that articulates with the tergum, but more often it looks like a low tubercle or plate-like structure that bears several long setae (see cercal plate); sometimes called the pygostylus.

( cerci, pl.): One of a pair of peg-like appendages on the end of the grasshopper abdomen. (Fig. 1)
an appendage (generally paired) of the tenth abdominal segment (called a tergum). It is conventionally considered to be a sensory appendage that is usually slender, filamentous and segmented. View image
The paired appendages at the end of the abdomen.
A paired, posterior, sensory appendage of the last (morphological tenth) abdominal tergum, which usually bears setae. With a reduction of the apical segments of the metasoma, the cerci often appear to be on a more anterior segment
one pair of appendages at the hind end of the abdomen
Appendage on terminal abdominal segment
Cerci (singular cercus) are paired appendages on the rear-most segments of many arthropods, including insects and arachnids but not crustaceans. Cerci often serve as sensory organs, but they may also be used as weapons or copulation aids, or they may simply be vestigial structures.
