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 ).
