longitudinal sulcus, interocular sulcus; posteromedian longitudinal and posterolateral sulci present and conspicuous, but not very deep.
It lies in an anteromedian
position and leads into the posterior cranial fossa.
Lingual propulsive pressures across consistencies generated by the anteromedian
and posteromedian tongue by healthy young adults.
The m1 anteromedian
flexid is deeply developed as in the other species of Postcopemys.
Statistical analyses of measurements of anteromedian
aspects of the face (mean [+ or -] SD in millimeters) showed nonsignificant higher mean values ( P > 0.05) in 87.5% of parameters: Total face height, short forehead height, long forehead height, upper face height, morphological face height, nasal bridge length, and nose height in Yoruba males compared to females [Table 1].
The length of their scutum is longer than its breadth and neither species has an anteromedian
projection nor an anteromedian
rays of anal fin of females elongated, anal fin shape nearly triangular.
These are 4X smaller than the anterolateral and anteromedian
Medium to large flies; male holoptic; lower calypter narrow, rounded posteriorly, with anteromedian
angle distinctly lateral to base of scutellum, not directed towards the scutellum; subcostal sclerite and basal section of stein vein bare (remigium); apical tip ofparaphallus with denticles.
Head yellow with antenna dark brown (Figures 10 and 11); mesosoma yellow, mesoscutum with lateral and anteromedian
dark marks (not longitudinal vittae) (Figure 11) and with propodeum brownish yellow; metasoma reddish brown (Figure 10).
Sensory area of profurcasternite small and only covering anteromedian
portion of segment, strongly convex.
nucleus is located at the midline of the rostral (superior) pole of the complex, with the Edinger Westphal nuclei adjoining it just caudally and laterally.
