brownish black, black and almost equilateral.
1D): Oval body, dorsally convex; light browned head wider than longer and with the tylus surpassing the juga; four dark browned spines at the margin of the jugum; pale reddish eyes; pale yellowed rostral segments, reaching the basal part of the metanotum; light browned antennal segments I-III, pale yellowed antennal IV segment; light browned pronotum wider than longer with dark browned deep punctuations at its surface and with the anterolateral light browned margin smooth and carinated; white mesonotum with disperse punctuations at the basal part; wing pads evident; scutellum
wider than longer covering slightly the metanotum; light browned anterior legs; paled yellowish middle and third pair of legs; white abdomen with dark browned mesial plates, slightly rectangular.
Thorax: Thoracic dorsum shiny black with yellow hairs, marginal hairs long and pale colored, forming yellow side line; bunch of yellow hairs on pleura; scutellum
raised golden color with yellow hairs
dark red-brown, largely apruinose except for silver anterior 1/3, fine dark red-brown setose (apical macrosetae poorly differentiated).
After several days of culture, an increased number of cell layers were observed in the scutellum
and coleoptile; the apical shoot was also evident in the region of the scutellar node (Figure 5G).
Explant source: Mature seeds were used as an explant source for callus induction from its scutellum
General coloration dark brown, with pale markings on scutellum
and hemelytra, legs predominantly golden-yellow (Fig.
Calypteres with dark edge; lower calypter with lobular internal margin, not directed towards the scutellum
flexella O O O Cocconeis heteroidea x Cocconeis scutellum
x Cocconeis scutellum
The nutlets form in a fruiting calyx called a scutellum
that expands in size and changes in color from green to yellow and finally brown.
Immature embryos were dissected from young caryopses under a stereo binocular and the embryonic axis was bisected longitudinally to destroy the embryonic axis, then after 3 days remaining embryonic tissue at the half scutellum
tissue was removed.
Basal area of propodeum approximately as long as scutellum
; metanotum approximately two-thirds length of scutellum
