Leiopodus trochantericus Ducke

DESCRIPTION OF MATURE OOCYTE (figs. 25– 28): Under both stereomicroscopic and SEM examination, dorsal surface of chorion irregularly uneven (fig. 25); opercular rim with edges rounded, slightly elevated; opercular disc with paired indistinct uneven protrusions; micropylar aperture of rim on anterior edge of rim; micropylar cluster of pores not visible on late­stage mature oocytes because it is obscured by follicular debris but distinct on somewhat earlier stage mature oocyte (fig. 28).

REMARKS: Figure 27 is considered to show an earlier stage mature oocyte because the opercular rim is sharper and the disc of the operculum and dorsal surface are far more even than those shown in figure 25. Because of the distinct polygonal patterning of the posterior and lateral parts of the chorion, figure 26 may show an even earlier stage.

Figs. 25–28. SEM micrographs of mature oocyte of Leiopodus trochantericus. 25. Entire late­stage oocyte (except for posterior tip), dorsolateral view; note uneven dorsal chorion behind operculum. 26. Posterior part of early­stage oocyte, dorsolateral view, with dorsal chorion nearly smooth and strong polygonal pattern at posterior end. 27. Intermediate­stage mature oocyte, nearly dorsal view, with dorsal chorion becoming uneven. 28. Close­up of micropylar area identified by rectangle in fig. 27.
