Eurema agave

description: Eurema agave
(Figures 2–3). Chorion 853 µm long and 283 wide; three times as long as its maximum diameter; a length (l)/width (w) ratio almost 1/3 (h=7). Color N 00 A 10 M 00. Semifusiform and slightly oblong chorion, with convex base and apex; the apical region is somewhat wider than the basal region (Fig. 2 A). The micropyle or micropylar polygon is irregularly hexagonal and surrounded by a rosette of seven petals, one of them anchored to one of the six micropylar openings (Fig. 2 B – i). The micropylar polygon is depressed with respect to the rosette, but both have rounded edges (Fig. 2 B). The petals show a conspicuous anchorage to the polygon although all have thin lateral walls (Fig. 2 B). Petals do not exhibit texture as the foils (Fig. 2 B – C). The perimicropylar region shows an irregular wreath of 10 foils in a poorly defined semi-ring; the foils have curved edges and four to six irregular sides (Fig. 2 C). The walls of the foils and the external ones of the rosette have almost the same thickness as the rest of the exochorionic grid (Fig. 2 B – D). No transition zone posterior to the wreath is distinguished, only the most apical polygons with a marked rough texture compared to those of the perimicropylar zone (Fig. 2 C – ii, D). The apical pores, possibly aeropyles or hydropyles, start in the cells adjacent to the wreath; they are semicircular and located singly at the vertices of the polygons (Fig. 2 D – E). There are 4 – 6 aeropyles at vertices aligned in an apex-equator direction (Fig. 2 C), with an incipient rough texture in the lumen of the polygons (Fig. 2 E – iii). Axes and ribs are not distinct towards the equator, but a grid of irregular polygons with four to six sides (Fig. 2, Fig. 3 A). Almost all of the polygons show the same size (Fig. 3 A), although the apical ones are slightly more elongated (Fig. 2 A, D, E). A subtle rough texture is present, without forming striae (Fig. 3 A – i). The micro-grid is absent. Parallel to the chorionic equator, we recorded 18—20 polygons (Fig. 2 A). The grid goes from one pole to another (Fig. 2 A), conspicuous from the apex, and fades slightly towards the base (Fig. 3 B). The prebasal zone exhibits the same texture, but is more tenuous or with little relief (Fig. 3 B – C). The grid keeps its thickness until reaching the base, where aeropyles are observed at some vertices; 3–5 by alignment (Fig. 3 B – ii, C). In the basal area, the grid and texture are blurred, so it is recorded as almost smooth (Fig. 3 B).
