THE GREEN LACEWINGS OF THE WORLD: A GENERIC REVIEW (NEUROPTERA: CHRYSOPIDAE) 247. 497 Figs 492-497 Gonzaga. 492, 493,495, G. torquata; 494,496, 497, G. nigriceps. 492, fore wing (from Kimmins); 493, apex of 6 abdomen, lateral; 494, apex of 9 abdomen, lateral; 495, 6 genitalia, dorsal; 496, $ spermatheca, lateral; 497, 9 subgenitale, ventral. species placed in Leucochrysa, such as L. risi which has extensive dark brown wing markings, appear to be very closely related to Gonzaga. However, males of Gonzaga share several syna- pomorphies, which do not occur in Leucochrysa, and which suggest that the genus is distinct. In Gonzaga there is a short lobe at the apex of the ectoprocts, there is no suture between sternites 8+9 and the arcessus is narrow with dorsal striations. Gonzaga may be distinguished from other chrysopid genera by the very long antennae, conspicuous black wing and head markings and the rectangular intramedian cell. Banks (1944) noted that the costal stigmal area is usually twice as broad as the subcostal stigmal area in Gonzaga but in Leucochrysa the costal stigmal area is rarely twice as broad as the subcostal stigmal area. However, there are so many exceptions to this in each genus that the character is practically worthless. Biology. Unknown. Genus LEUCOCHRYSA McLachlan Leucochrysa McLachlan, 1868: 208.
