The dorsal facet has a straight dorsal border, ventrolaterally
inclined lateral sides and a curved ventral border.
It is limited rostrolaterally with the ectethmoid bone and ventrolaterally
it contacts the rostroparasphenoid and to the palatine and ventrolaterally
to the pterygoid in all the species studied.
The epiphallic membrane runs backwards from the epiphallus to anchor on the zygoma and the edges of the ectophallic rami; there are no postepiphallic sclerites, but in some individuals there is a weak oblong thickening of the membrane ventrolaterally
, anterior to the the cingular rami.
Paramere shallowly sinuate laterally, strongly sinuate against median lobe; apices broadly rounded, ventrolaterally
In the neurocranium, nasal capsules expand ventrolaterally
; in Urotrygon nana and Urotrygon munda the capsules migration towards the ventral region is barely evident (Fig.
On physical examination, a periorbital mass (2 cm in diameter) was present on the dorsomedial aspect of the right eye, displacing the globe ventrolaterally
These boundaries include the parietal pleura ventrolaterally
; heads of the ribs, transverse process, and superior costotransverse ligament dorsally; and vertebra, intervertebral discs, and intervertebral foramina medially.
Terminaba (Figure 5): gonocoxite not splayed, about 2.7-3.0 times as long as wide, about 1.9-2.0 times as long as gonostyhis and setose; gonostyhis clavifonn, tapering from base to apex, setulose on basal third, glabrous and ridged beyond to apical tooth; posterior margins of cerci and hypoproct evenly convex posteriorly, all 3 subequal in shape, the cerci with several setae ventrolaterally
and apically, hypoproct with 3 setae along posterior margin about as long as cerci; parameres longer than hypoproct, covered with elongate, recurved setulae, bilobed, the dorsal lobe short, convex, the ventral lobe longer, larger, projecting dorsally in lateral view; aedeagus glabrous, longer than mediobasal lobe, tapering gradually to apex, the apex convex in dorsoventral view.
The preserved portion of the coracoid process curves ventrolaterally
as in Myotis and other vespertilionids rather than curving ventromedially as in molossids.
Posterior margin more or less trilobed, and the ventral lobe more prominent than the others, bending ventrolaterally
. The ventral lobe of the lateral arm in some specimens was larger in the dorsal view (Fig.
linearis) and all Belostomatidae, Gelastocoridae, Naucoridae, Pleidae, Helotrephidae, and Notonectidae (2) Ventrolaterally
extended maxillae with a wide lobe; Aphelocheiridae (3) Pentagonal-shaped maxillae with two external lobes; Ochteridae (4) Oval maxillae, flattened laterally without the external lobe; Ranatra chinensis, R.
The defect was located laterally or ventrolaterally
in all cavernosal injured cases.
