Lacroix commented on the lack of Sc crossveins in the pterostigmal region: these are present in Tjederina but are often difficult to see. Biology. The larva of P. gracilis has been described by Gepp (1983) and is said to be associated with conifers. No insect remains were found in the guts of adults examined during this study. Genus PLESIOCHRYSA Adams stat. n. Plesiochrysa Adams, 1982a: 28 [as subgenus of Chrysopa Leach]. Type species: Chrysopa brasiliensis Schneider, by original designation. Distribution. Neotropics, Oriental, Australasia. The genus includes 23 described species and several undescribed ones are in the BMNH collec- tions. Five species occur in the Neotropics and the rest are widely distributed from Australia and the Pacific Islands, through Malaysia to southern India and the Seychelles. Plesiochrysa ramburi (Schneider) is common and occurs through-out Austro-Malaysia and most of Micronesia. Diagnosis. Adult. Medium to large lacewings, fore wing (Fig. 439) 13-18 mm; ground colour pale green. Head unmarked or with red or yellow markings on gena, clypeus, frons, vertex, mark- ings sometimes black; palps tapered apically; mandibles broad, asymmetrical with basal tooth on left mandible; galea variable (Figs 440, 441); labium indented; vertex slightly raised; head width : eye width = : 1; antenna slightly longer or shorter than fore wing; scape as lo
