FIGURE 8. Scanning electron micrographs of Pegmatothylakos manumii sp. nov. (NRMS089730). 1, Cocoon in lateral view. 2, Enlargement of robust reticulate pegmatine covering thread-like hapsine. 3, Enlargement of areole in pegmatine reticulum showing underlying mesh-like hapsine. 4, Enlargement of girders forming pegmatine showing hackly inner zone and smoothly welded threads lining girder margins. 5, Detail of hackly and smooth threads in pegmatine girders. 6, Broken pegmatine girder showing irregular internal structure. 7, Enlargement of interior surface of pegmatine girder showing smooth threads with irregular branching and orientation. 8, Enlargement of hapsine threads. Scale bars represent 1 mm in 1; 250 μm in 2; 100 μm in 3, 4; 25 μm in 5–8.
