Conochitina viruana has usually a
foveolate vesicle wall ornamentation, although rarely smooth specimens are encountered as well.
The pronotum, dorsum of the mesonotum, and dorsum of the propodeum are coarsely
foveolate and rough.
Pollen grain morphology Triporate, Oblate spheroidal, pore more or less circular, operculate, fossulate-
foveolate, and exine 2.5 [micro]m thick (Figure 3).
Dorsum of head densely sculptured with very small, shallow
foveolate punctures, broadly separated; mid dorsum to almost all of promesonotum with dense, fine longitudinal striations mixed with scattered small punctures, periphery of promesonottum, dorsal and posterior face of propodeum and petiole densely reticulated.
Pollen wall ornamentation is reticulate or finely reticulate (van Zinderen Bakker, 1953; Sharma, 1968; Ybert, 1979; Cruz-Barros et al., 2000) and punctate (Sharma, 1968), or
foveolate (Sharma, 1968; Straka & Friedrich, 1984).
The shell of Vaceuchelus species is small (length <10 mm), predominantly white and has a cancellate or
foveolate sculpture.
Prothorax.--Disk campanulate,
foveolate; cervical sulcus moderately deep, extending from near coxal cavity to about 0.56 to 0.63 distance to pronotal midline (Fig.
The apical whorls are sculptured only with axial pliculae and subsequent whorls with both spiral cords and axial pliculae that interact to produce a cancellate or
foveolate sculpture (not obviously beaded).
