. We describe two new species of Blepharoneura (Diptera: Tephritidae) from Venezuela and Trinidad and redescribe Blepharoneura atomaria (Fabricius), comb.n. Each of the morphologically similar sympatric species feeds on a different tissue of Gurania spinulosa Cogn. (Cucurbitaceae): seeds ( B.manchesteri , sp.n.), male flowers ( B.atomaria ), and female flowers ( B.perkinsi , sp.n.). With the help of elementary school children and teachers we developed new methods for detecting and describing wing patterns. We present frequency distributions of character states and describe a denticulate area within the distiphallus that may function as a holdfast. For each species we provide notes on the ecology and behaviour of larvae and adults.
