Comments. Males, females and eggs of this species were described by Zwick (1981) from approximately 120 specimens collected in Kerala and Tamil Nadu states, South India. In his description, Zwick (1981) notes the variable adult color pattern which is also evident in our samples. The most heavily pigmented individuals we observed had a small dark spot extending forward from between the ocelli and terminating in an acute line. These specimens also have a small dark spot near each tentorial callus, dark lappets and a prominent, median bell or triangular spot on the anterior frons, but other specimens have almost no dark head pigment. The specimens listed above include three topotype males and the first records from Karnataka State. In addition to the specimens listed above, two males in the USNM collection, from Orissa State, Jeypore, 1775’, collected in September 1958 by P. Susai Nathan, are similar in aedeagal shape and general features, but appear slightly different in having an area near the tube apex covered with small spicules rather than the patch of larger spines found on other specimens. The aedeagal sac armature for these specimens also shows some variation from typical N. biseriata and N. ochracea . These specimens may represent an additional species in this complex but are not treated as such until additional data are available for the group.
