6--KEYS TO FEMALES AND LARVAE OF THE ANGOLAN MOS-<br />

QUITOES<br />

The c<strong>on</strong>structi<strong>on</strong> <strong>of</strong> our keys was mainly based <strong>on</strong> <strong>the</strong> classical<br />

works <strong>of</strong> Edwards (8) and Hopkins (24) as well as <strong>on</strong> o<strong>the</strong>r fur<strong>the</strong>r c<strong>on</strong>tributi<strong>on</strong>s,<br />

such as those <strong>of</strong> van Someren (25) (26), Mattingly (27) and De<br />

Meill<strong>on</strong> et al. (28). On <strong>the</strong> o<strong>the</strong>r hand, attempts were also made by <strong>the</strong><br />

writers in order to improve <strong>the</strong> usual keys by precising some diagnoses<br />

and by taking into account <strong>the</strong> range <strong>of</strong> variati<strong>on</strong> observed in <strong>Angola</strong>n<br />

material.<br />

It must be noted, however, that individual larvae <strong>of</strong> C. antennatus,<br />

C. decens, C. invidiosus, C. telesilla, C. trifoliatus and C. univittatus are<br />

<strong>of</strong>ten indistinguishable, even though <strong>the</strong> identificati<strong>on</strong> <strong>of</strong> samples <strong>of</strong> <strong>the</strong>se<br />

species will be usually feasible using <strong>the</strong> larval key here proposed.<br />
