Revised diagnosis

Species of average size, colouration contrasting with black and yellow, characterised by black vertex, frons yellow, orange brown legs. Male area between M and R yellow, veins black or yellow; cells beneath R partly yellow, otherwise transparent.Anal-most and middle chords distinctly diverging apically, basalmost chord extend from midpoint/after midpoint of middle chord. Female copulatory papilla without truncated lobule at ventro-anterior end. Species very similar to N. malaya   sp. nov., from which it differs by male genitalia with pseudepiphallus faintly less robust, narrower, anterior margin less concave; female copulatory papilla without truncated lobule at ventro-anterior end. Juvenile differs strikingly in colour patterns. Male calling song also differs by shorter echeme period.

Redescription

Size average ( Figs 2 View Fig , 23E–H View Fig ), similar to N. malaya   sp. nov. but differs by slightly lighter colouration, male genitalia, female copulatory papilla and juvenile colouration.

Male

GENITALIA ( Fig. 16G View Fig ). 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. 17P–Q View Fig ).

Juvenile ( Fig. 24D–F View Fig )

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. Cerci whitish with a black stripe.

Ecology

This species can be found among shrubs and herbaceous plants (but not grasses) at the forest edge ( Fig. 27A View Fig ). Similar to N. malaya   sp. nov., the adults and nymphs of this species have been observed in Brunei Darussalam to feed on the flower parts of a varieties of native and exotic plant species ( Tan et al. 2017).

Distribution

Sumatra, Borneo.

Type locality

Indonesia: Sumatra: Lampongs, Wai Lima.

Calling song (Kuala Belalong, n = 2 males, 20 echemes; MNHN-SO-2020-2859 to MNHN-SO-2020-2860) ( Fig. 25D–F View Fig )

At 27.0°C, the calling song consists of long homogeneous bouts made of short echemes consisting of triplets of syllables; echeme duration is 32.47± 3.79 ms (27.00–38.65 ms); echeme period is 55.20±5.90 ms (50.52–74.27 ms); downtime between consecutive echemes is 22.73 ± 7.26 ms (14.16–41.82 ms). Durations for the first to third syllables of the triplet are as follows: 6.93 ± 1.73 ms (4.57–9.95 ms), 7.51 ± 2.03 ms (4.80–11.67 ms) and 7.22 ± 2.82 ms (3.24–12.44 ms). The call spectrum consists of a series of harmonics with three distinct peaks corresponding to the first three harmonics: first harmonic (fundamental frequency) at 6.86 ± 0.28 kHz (6.46–7.15 kHz), is usually the dominant frequency; second harmonic peaking at 14.08 ± 0.39 kHz (13.35–14.64 kHz); third harmonic peaking at 19.96 ± 0.35 kHz (19.12–20.67 kHz).

Remarks

See N. malaya   sp. nov. for arguments about considering two distinct species.

About synonymy of Nisitrus marginatus ( Walker, 1869)   under N. vittatus   , considering that N. vittatus   is variable in colouration and widely distributed in Borneo and Sumatra, and that the only known syntype of N. marginatus   from Sumatra resembles N. vittatus   , we consider the species described by Walker (1869) as a junior synonym of N. vittatus   .
