Depending on position on host, either rotund or elongate oval; convex in cross section; body reddish or brownish yellow, with brown marginal area, specimens becoming dark brown at maturity; many specimens with derm shiny; without wax on dorsum; without an ovisac. Occurring on stems and fruit.
This species was intercepted 49 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from Burkina Faso, Cameroon, Côte D’Ivoire, Gambia, Ghana, Guinea, India, Nigeria, Senegal, and Sierra Leone. We also have examined specimens taken in quarantine from Ghana (Cola); Côte d'Ivoire (Mangifera); Nigeria (Annona, Cola, Mangifera); Senegal (Mangifera); Sierra Leon (Mangifera); Zambia (Mangifera). We also have examined specimens from 3 questionable localities: Colombia (Mangifera); India (Mangifera); Trinidad (Mangifera); these records may be erroneous since they are based on single quarantine interceptions except that the species has been intercepted twice from India. ScaleNet lists hosts in 16 plant families and most interceptions have been on Mangifera. ScaleNet distribution records for U. catori include only the Afrotropical region. Two other species of Udinia have been taken in quarantine in addition to U. catori and U. farquharsoni (Newstead): U. pattersoni Hanford (Cameroon, on Coffea); and U. setigera Newstead (Côte D`Ivoire, on Mangifera).
