Chrysopa sp. : Grimaldi and Engel, 2005: 351, fig. 9.30.

DIAGNOSIS: This species differs most notably from C. vetula , also in Dominican amber,

by the submedian longitudinal stripes on the pronotum and larger size. Other differences are presented in the following description.

DESCRIPTION: Forewing length 16 mm; total body length 12.1 mm; pronotum length 1.0 mm, width 1.25 mm. Integument generally golden with faint green highlights except when indicated below; integument faintly imbricate. Palpi tapering at apices; labrum emarginate; lateral quarters of clypeus black; scapes close together with black on inner surfaces; flagellum about as long as forewing.

Pronotum with two narrow, longitudinal stripes of dark brown on either side of midline, lateral margins not marked, slightly wider than long, anterior margin broadly rounded; meso- and metathoracic pleura dark brown, mesothorax with narrow, longitudinal stripes of dark brown on either side of midline, laterally unmarked.

Forewing oval and broad, longer than abdomen, with sparse setae except along margins; 22 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), four sc-r crossveins below pterostigma; pterostigma elongate and unmarked; cell m1 much smaller than m2 (as typical for Chrysopa , while in Plesiochrysa these cells are closer in size); cell im ovate, broad, 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 ( fig. 27 ). Hindwing with two gradate series. Wing membrane hyaline; veins light brown.

Abdomen apparently with basal bands of dark brown on terga; eighth and ninth terga not fused; sternum two without stridulatory apparatus; callus cerci rounded.

HOLOTYPE: Female ; MACT-1221 ( figs. 26– 27 ), Miocene amber of the Dominican Republic.

ETYMOLOGY: The specific epithet is derived from the Latin word glaesarius, meaning ‘‘of amber’’.
