carsoni sp. n.
Anisodes dimerites Prout
sensu, Holloway, 1976: 63,
13-15mm. The facies is essentially similar to that of dimerites but
there is much greater variability, with forms shaded darker red in the medial
zones of both wings or just along the medial with a streak of a darker marginal
patch at vein M2. Another common form has black flecks on the veins within the
medial, post- and antemedial fasciae (a form also seen in C. subrosea Warren
comb. n. ). In the male genitalia the valves have a strongly concave
costa with square and triangular processes close together at its distal end. The
aedeagus is short, broad, with a mass of robust spines in the vesica. In the
female the ovipositor lobes are rather elongate and the bursa very small,
bilobed, on a short ductus, with very fine spining only.
