Chrysopa ? vetula , new species figures 28–31

DIAGNOSIS: Refer to diagnosis presented for C. glaesaria (above).

DESCRIPTION: Forewing length 9.7 mm; total body length 7.6 mm; pronotum length 0.7 mm, width 0.75 mm. Integument generally golden with faint green highlights except when indicated below; integument strongly imbricate. Palpi tapering at apices; labrum emarginate; lateralmost borders of clypeus black; scapes close together with black on inner and outer surfaces; flagellum about as long as forewing.

Pronotum with two narrow, longitudinal stripes of dark brown on lateral borders, slightly wider than long, anterior margin broadly rounded; meso- and metathoracic pleura apparently light brown, mesothorax with narrow, longitudinal stripes of dark brown on anterolateral margins.

Forewing oval and broad, longer than abdomen, with sparse setae; 18 costal crossveins (c-sc); costal area narrows progressively toward apex; Sc and R deviate slightly near apex, Sc joins C at apex; R straight, not sinuous; single sc-r crossvein toward wing base (vein bsc), three sc-r crossveins below pterostigma; pterostigma elongate and unmarked; cell m1 much smaller than m2; cell im ovate, relatively narrow, first rs-m crossvein meets im subapically; no radial crossvein (r-m) basal to origin of Rs, radial crossveins straight; cell c1 shorter than c2; cell dcc narrowly open along posterior wing margin; six closed cells between PsM and PsC; two gradate series, inner gradate series incomplete, anterior gradates absent, gradates parallel; 1A forked. Hindwing with two gradate series. Wing membrane hyaline; veins light brown.

Abdomen apparently light brown, somewhat distended; eighth and ninth terga apparently not fused; sternum two without stridulatory apparatus.
