Key to genera and most subgenera of Mymaridae View in CoL View at ENA from Europe (males)

(Males are recognized by antenna lacking clava, the apical flagellar segment(s) not wider than remaining flagellar segments. Note: In Europe, males are unknown for Omyomymar , Ptilomymar , Pseudocleruchus and Palaeoneura . If/when discovered, they will most likely be identified by the features given in the key to females. Although the figures are of females the same figures are given in the key to males; apart from sexual differences in the genitalia and antenna the structures are usually the same. Remarks on distribution and literature for each genus are given only in the key to females.)
