Diagnosis

Average size, colouration contrasting with black and yellow, characterised by black vertex, yellow frons and orange brown legs. This new species is very close to N. vittatus   from which it differs by adult and juvenile colouration, male and female genitalia and calling song. General colouration darker, particularly among FW cells and veins beneath R; R black (instead of cream-coloured as in N. vittatus   ); in male venation, anal-most and middle chords narrow and nearly parallel with one another (instead of diverging apically), and basal-most chord extend from basal half of middle chord (instead of at/after midpoint). It differs from N. vittatus   by the male genitalia with pseudepiphallus more robust, broad, anterior margin more strongly concave. Female copulatory papilla with truncated lobule at the ventro-anterior end. Juvenile differs strikingly in the body colour pattern. Male calling song also differs by longer echeme period. This species is also similar to N. crucius   sp. nov. in size and habitus, but differs by the absence of cross-shaped black pattern on frons and does not occur in Borneo.

Etymology

This specific name is a noun in apposition referring to the speciesʼ distribution in the Malay Peninsula (including Singapore and Peninsular Malaysia).

Description

Habitus similar to N. vittatus   ( Figs 7E View Fig , 23A–D View Fig ): vertex black with cream-coloured margin around eyes ( Fig. 11F View Fig ). Fastigium velvety black with cream-coloured margins. Scapes dark red brown to black (particularly on dorso-inner margins). Antennae black with wide whitish rings. Frons and mouthparts most often yellow with a few dark spots ( Fig. 10F View Fig ). Maxillary palpi cream-coloured, apical segment black apically. Head lateral side yellow, with a wide black band posterior to eye ( Fig. 12F View Fig ). Pronotum covered with white setae; dorsal disk dark red brown to black ( Fig. 11F View Fig ); lateral lobes of pronotum dorsal third black, vivid yellow ventrally (cream-coloured in preserved specimens) ( Fig. 12F View Fig ). Legs dark orange brown. FIIIs brown, knees dark brown to black; TIIIs brown with black spines and spurs, dark brown to black near distal end; tarsomeres dark brown to black. Hindwings hyaline brown apically, transparent basally; longer than FWs, forming a dark brown tail exceeding FWs for more than twice the length of pronotum. Tergites red brown, with a pale band laterally; sternites pale, with a red brown median area. Cerci red brown, lighter dorsally.

Male

FOREWINGS. FW colouration ( Fig. 13E View Fig ): dorsal field cells mostly transparent, veins mostly dark brown to black. Basal FW area black (instead of cream-coloured or brown as in N. vittatus   ), with a relatively small cream-coloured patch basally. R black (instead of cream-coloured as in N. vittatus   ), Sc projections cream-coloured basally, black apically. Apex of dorsal field somewhat truncated. Lateral field dark. FW venation ( Fig. 13E View Fig ): 1A curved, slightly angulated. Harp slightly longer than wide, with 3 oblique veins, basal one bifurcated distally, distal one bifurcated basally. c1 long and wide, c2 diamond-shaped; mirror (d1) longer than wide, not rounded, generally separated into two parts by a distinct transverse vein, the posterior part nearly rectangular, shorter than anterior part. Cell d2 narrower than d1. Anal-most and middle chords narrow and nearly parallel; basal-most chord extending from basal half of middle chord. Apical field short and rounded, with 3 wide cell alignments posterior to mirror and a narrow apical alignment; veins cream-coloured. Lateral field with 5 projections of Sc. Epiproct black. Subgenital plate pale cream-coloured with median area and anterior and posterior margins black.

GENITALIA. Very similar to N. vittatus   ( Fig. 16E View Fig ) but differ by pseudepiphallus faintly less robust and broad, anterior margin more strongly concave. Rami more strongly curved.

Female

FOREWINGS. FW colouration ( Fig. 14F View Fig ): cells black, veins generally cream-coloured. Without distinct longitudinal white stripe around region of CuA, M and R with distinct margin from black colouration on dorsal field; Sc projections cream-coloured basally, black apically. Lateral field dark. FW venation: 6–7 strong longitudinal veins on dorsal field; lateral field with 6 projections of Sc.

GENITALIA. Ovipositor about as long as FIII. Copulatory papilla conical, small and stout; apex folded ventrally, short, pointed; dorsal face with a sclerotized area; ventro-anterior end forming a truncated lobule ( Fig. 17J–K View Fig ).

Juvenile ( Fig. 24 A–C View Fig )

Differing from that of N. vittatus   by darker colouration, usually grey, never as white as N. vittatus   . Stripes on head similar to N. vittatus   but sometimes very faint; pronotum dorsal disk homogeneously dark grey, without longitudinal stripes; sometimes with a large velvety black spot. Legs grey with dark stripes, but stripes not as distinct as in N. vittatus   . Abdominal tergites dark grey, their posterior margins thinly lined with yellow, not forming a pattern of transverse stripes. In some individuals, first and second abdominal tergites with a particularly dark (black), velvety band.

Ecology

This species can be found among shrubs and herbaceous plants (but not grasses) ( Fig. 27 View Fig ). The adults and nymphs from Singapore and Malaysia (previously reported as N. vittatus   ) have been reported to feed on the flower parts of a varieties of native (e.g., Dillenia suffruticosa (Griff.) Martelli   ) and exotic weedy (e.g., Lantana camara   L.) plant species ( Tan et al. 2017). They also feed on the foliages of understory plants such as Piper sarmentosum Roxb.   ( Fig. 27 View Fig ). In Singapore, N. malaya   sp. nov. can be found abundantly in the understory where Piper sarmentosum   dominates.

Distribution

Malay Peninsula ( Singapore and Peninsular Malaysia [northern limit at the state of Penang]) ( Fig. 5 View Fig ).

Type locality

Singapore.

Calling song ( Singapore, n = 4 males, 20 echemes; MNHN-SO-2851–2854) ( Fig. 25A–C View Fig )

At 27.3°C, the calling song consists of bouts of highly variable length, ranging from a few seconds to several minutes. Each bout is composed of short echemes made of triplets of syllables; echeme duration is 32.3 ± 2.8 ms (29.0–37.56 ms); echeme period is 64.5± 4.3 ms (59.5–75.5 ms); downtime between consecutive echemes is 32.1 ±4.4 ms (24.3–41.3 ms). Durations for the first to third syllables of the triplet are as follows: 6.1 ±1.5 ms (3.7–8.0 ms), 6.7 ± 2.7 ms (2.5–10.6 ms) and 5.8± 2.9 ms (3.0–11.2 ms). Call spectrum consists of a series of harmonics with three distinct peaks in the first three harmonics: first harmonic (fundamental frequency) at 7.35± 1.28 kHz (6.201–9.39 kHz), which is also the dominant frequency; second harmonic at 13.33± 1.01 kHz (12.23–15.07 kHz); third harmonic at 18.88 ±0.77 kHz (17.23–20.07 kHz).

Remarks

We split the species previously recognised as N. vittatus   into two distinct species after integrating evidence from general and nymphal colouration, female genitalia morphology, acoustics, DNA (12S sequence) and distribution. In terms of adult morphology, the new species is very similar to N. vittatus   in habitus, other than being darker in colouration. The male genitalia are not always distinguishable between these species; but the sclerotization of the female genitalia can be differentiated. However, the colour patterns in the nymphs are drastically different. Likewise, a multivariate analysis of the call properties also showed distinct calling songs. The 12S gene tree also demonstrates that the two species form distinct clades. Lastly, the new species occurs in Malay Peninsula whereas N. vittatus   occurs in Borneo and Sumatra. Integrating these pieces of evidence indicates that N. vittatus   and N. malaya   sp. nov. are indeed separate species having probably diverged recently, despite the similarities in adult habitus and male genitalia.
