[email protected]) Abstract. — The only known male specimen of the rare New World genus Loyola Navas has genitalic characteristics that are generally consistent with those described for its sub-family, Apochrysinae. The genital characters are also consistent with the placement of the genus in the Joguina clade of Apochrysinae. Our specimen of Loyola croesus (Gerstaeck-er), one of three species in the genus, has several distinguishing genitalic features; whether these features typify the genus Loyola or only L. croesus, is unknown. Key Words: Chrysopidae, Loyola, Joguina clade, Apochrysinae, green lacewings Apochrysinae is a small, largely tropical subfamily of strikingly handsome, but rare-ly encountered green lacewings. Adults have slender, graceful bodies and broad, delicate wings that are often elaborately marked or have densely reticulate venation. For some genera only one sex is known, and with one exception, Apochrysa (= Na-caura) matsumurae (Okamoto) (Tsukaguchi 1995), the biological characteristics and im-mature stages of all members of the sub-family are unknown. In a recent phylogenetic study, Winterton and Brooks (2002) confirmed the monophy-ly of the subfamily and reduced the 1 3 pre-viously recognized genera to six. Of these, three occur in the New World, specifically. Central and South America. They are Do-menechus Navas (known only from the New World; two species — one each from Guatemala and Brazil), Joguina Navas (five species in total: three from the Orient, two from the New World — one each from Gua-temala and South America), and Loyola Na-vas (known only from three New World species: two from Brazil, the third from Mexico, Nicaragua, Costa Rica, Panama, Venezuela, and Brazil; previously known only from females). Together with the Ori-ental genus, Nobilinus Navas, these three genera comprise the Joguina clade of Apochrysinae (Winterton and Brooks 2002). The male terminalia of Apochrysinae are reduced and vary only in minor respects among taxa. Nevertheless, they provide some characters that are useful in identify-ing species and in helping to discern phy-logenetic relationships, both within Apoch-rysinae and between Apochrysinae and oth-er chrysopid taxa (Winterton and Brooks 2002). Thus, the lack of information on males in the genus Loyola left a distinct gap in the knowledge of New World Chryso-pidae. During a recent field trip in the Mata At-lantica of the State of Rio de Janeiro. Bra-zil, one of us (GSA) collected a male of Loyola croesus (Gerstaecker).
