Eurema albula sinoe

( Fig. 4 D View FIGURE 4 , Figs. 7–8 D – F View FIGURE 7 View FIGURE 8 ). Chorion 1345 µm long and 339 wide; 3.9 times longer than the equatorial width—where it is the maximum—and ratio w/l of almost 1/4 (h=10) ( Fig. 4 D View FIGURE 4 ). Color N 00 A 10 M 00. Semifusiform with a weak, slightly convex base and a convex apex of nearly the same width ( Fig. 4 D View FIGURE 4 ). The micropyle is a very irregular pentagonal polygon, barely depressed relative to the five petals rosette ( Fig. 7 D View FIGURE 7 ). The petals have rounded vertices and a subtle anchorage with the central polygon, with thinner lateral walls than the external ones ( Fig. 7 D View FIGURE 7 – iii). The perimicropilar region has an irregular wreath of 16 curved-edged foils whitin a poorly defined semi-ring. The foils are semi-elliptical polygons with four to six irregular sides each ( Fig. 7 E View FIGURE 7 ), with some of them with incipient or absent walls that are only distinguished by the margins of the external walls ( Fig. 7 E View FIGURE 7 ); both the micropylar and perimicropylar zones are smooth ( Fig. 7 D – E View FIGURE 7 ). No transition zone is distinguished posterior to the wreath ( Fig. 7 E View FIGURE 7 ), so it continues through the apical polygons with aeropyles at their vertices and an irregular micro-grid ( Fig. 7 E – F View FIGURE 7 ). The aeropyles are semicircular and arranged singly in a zigzag pattern that coincides with the vertices of the polygons ( Fig. 7 F View FIGURE 7 ; Fig. 8 D View FIGURE 8 ). 10–12 aeropyles aligned in an apex-equator direction at the vértices, with the two closest to the equatorial third of smaller diameter ( Fig. 7 F View FIGURE 7 – iv). The micro-grid has one to three irregular elliptical polygons in the closest to the wreath macro-grid cells ( Fig. 8 D View FIGURE 8 ), and 4–5 rounded polygons towards the equator, but all with subtle roughness in their lumen ( Fig. 7 F View FIGURE 7 ). Towards the equator, 19–23 nearly straight axes (37–40 in total) are recorded in lateral view—with fusions and bifurcations mainly at the poles—and 68–71 mostly straight ribs, with some diagonals and curves between the basal and apical thirds ( Fig. 4 D View FIGURE 4 ). The axes are 1.2 times thicker and protrude from the exochorion more than the ribs ( Fig. 8 E View FIGURE 8 ), which are slightly thicker than the micro-grid, so their differentiation is subtle ( Fig. 4 D View FIGURE 4 ; Fig. 8 E View FIGURE 8 ). Macro-grid cells are four- to sixsided irregular polygons ( Fig. 4 D View FIGURE 4 ; Fig. 8 E View FIGURE 8 ), almost all of the same size, except those with diagonal ribs ( Fig. 4 D View FIGURE 4 ). The micro-grid exhibits 5–8 irregular, quasi-elliptical to rectangular polygons per macro-grid cell, with incipient roughness ( Fig. 8 E View FIGURE 8 – ii). Macro and micro-grids exhibit a constant thickness towards the prebase ( Fig. 8 F View FIGURE 8 ), where it fades and is visualized as a texture with little relief. Basal aeropyles were not observed ( Fig. 8 F View FIGURE 8 ). In the basal zone, the edges of the polygons are completely blurred and only a rough texture is found ( Fig. 8 F View FIGURE 8 ).
