Nisitrus vittatus

Redescription Size average (Figs 2, 23 E – H), similar to N. malaya sp. nov. but differs by slightly lighter colouration, male genitalia, female copulatory papilla and juvenile colouration. Male GENITALIA (Fig. 16 G). Pseudepiphallus relatively slender, slightly longer than broad, anterior margin straight, posterior margin indented in median area to faintly concave, lateral margins with basal half converge posteriorly, apical half somewhat parallel. Pseudepiphallic lophi slightly longer than wide (at base), sclerotized laterally only and covered with strong short setae; their apex slightly folded dorsally and sub-obtuse; moderately spaced apart from each other. Similar to N. malaya sp. nov. but differs by pseudepiphallus faintly more robust and broad, anterior margin more straight. Rami more straight. Female GENITALIA. Copulatory papilla conical, smaller and stout; apex folded ventrally, elongated, pointed; dorsal face with a sclerotized area; ventro-anterior end with an oblong rim, without truncated lobule (Fig. 17 P – Q). Juvenile (Fig. 24 D – F) Characterised by pale white or yellow colouration with numerous dark stripes all around body. Dorsum of head with three transverse black stripes that extends to gena. Eyes with numerous dark stripes. Fastigium with margin black; antennal black with pale rings; frons with a few black spots; palpal segments white with apices black. Pronotum with three thick, dark longitudinal stripes on dorsal disk, one very thick velvety black stripe between dorsal disk and lateral lobe; another curved stripe on lateral lobe ventral of the thick stripe; these stripes not reaching margins. Fore and middle legs with longitudinal dark stripes, two on each face, usually one dorsal and one ventral. FIII with longitudinal dark stripes, two dorsally, and two ventrally. Thoracic (excluding pronotum) and abdominal tergites typically dark or greyish, anterior margin dark, their posterior margin whitish forming a homogeneous light / dark striped pattern.
