DESCRIPTION. Male. Coloration light yellowish with whitish tinge (very light greenish in living condition), slight greyish marks on lateral tegminal fields and on ventral surfaces of spines in fore and middle tibiae as well as on subapical segments in all tarsi, yellow stridulatory vein of left tegmen having small brownish spot on lateral part of this vein, brownish grey oblique oval ring on left mirror ( Fig. 1 ), and almost transparent rest membranes of dorsal tegminal fields. Head with strongly oblique anterior suface, small spinule-like upper rostral tubercle having shallow dorsomedian groove, rounded convexity instead lower rostral tubercle, and scape almost 4 times as wide as space between antennal cavities. Pronotum widest in middle part, slightly wider than long, with anterior and posterior edges roundly truncated, and with each lateral lobe low and having rounded ventral edge (anterior half of this lobe lower than posterior one and with more sloping ventral edge); thoracic venter with 3 pairs of spines (rather long on prothorax, moderately short on mesothorax, and very short on metathorax). Tegmina somewhat protruding beyond legitima sp. n.; 9, 10 – A. l. manukan subsp. n.; 11–13 – A. paracercalis sp. n.; 14, 15 – A.

bintulu sp. n. Dorsal field of left (1) and right (2) male tegmina; ovipositor from side (3, 8,

10, 13, 15); male genitalia from below (4) and from side (5); pronotum with bases of tegmina from above and slightly from side, male (6), female (7, 9); male body without abdominal apex from side (11); pronotum and tegmina of female from side (12, 14).

abdominal apex but clearly not reaching apical parts of hind femora, with stridulatory apparatus as in Figs 1, 2 ; hind wings distinctly not reaching tegminal apices (these apices more or less angular). Fore leg with 6 outer and 5 inner femoral spines, a pair of shorter and denticle-like apical spines (spurs), 6 pairs of very long tibial spines, a pair of short ventroapical tibial spines (spurs), and distinctly inflated but not large tympanal region having a pair of very large and oval tympanal openings almost equal to each other in size; middle leg with very small ventral spinule on trochanter,

5 outer femoral spines, 2 distinctly shorter inner spines on proximal part of femur, a

(Heb.); 31 – A. malacca Gor. ; 32 – A. bintulu sp. n.; 33–37 – A. paracercalis sp. n. Male abdominal apex without genital plate from above (16, 20, 25, 34) and from behind (17);

genital plate of male (18, 27, 37) and female (19, 22–24, 28–33) from below; male abdominal apex with genital plate from below (21) and from side (35) as well as without both this plate and distal cercal half from below (26, 36). [ Fig. 30 – after Tan (2011), modified].

spines, and 3 short tibial spurs (2 inner spurs and outer ventral one); hind leg with femur having a pair of short spurs and 16 outer ventral denticles similar to these spurs in length, and with tibia having 4 rows of rather numerous spines of similar length (but ventral spines less numerous in proximal half of tibia) and 2 pairs of barely shorter spurs. Last tergite slightly longer than previous abdominal tergites,

with wide and rather deep posteromedian notch; epiproct wide, almost fused with last tergite, and having short and rounded posteromedian projection; each paraproct almost triangular from behind but slightly vertical, clearly visible behind epiproct,

and with spinule-like posterodorsal process directed backwards ( Figs 16, 17 ); cerci simple, rather long and thin, clearly arcuate, and with narrowly rounded apices

( Figs 16, 17 ); genital plate long, with rather wide proximal half and narrow distal one, and with barely widened apex having shallow but angular posteromedian notch and almost lacking styles ( Fig. 18 ). Genitalia with ventral branch of median sclerite semisclerotized, moderately narrow and long, and having distal part gradually narrowing to narrowly rounded apex; dorsal branch of this sclerite shorter, wider and semimembranous; lower and lateral parts of genitalia with additional both semimembranous median plate and a pair of semisclerotized spine-like structures around median sclerite ( Figs 4, 5 ).

Female. General appearance as in male, but upper rostral tubercle less acute at apex, pronotum widest somewhat behind its middle, tegmina uniformly light as well as without stridulatory apparatus and with narrowly rounded apices, last tergite and epiproct smaller, paraprocts rounded and without processes, and cerci more or less similar to those of male in shape but smaller and with almost acute apices;

genital plate very short and with wide and almost truncated posterior edge ( Fig. 19 );

ovipositor as in Fig. 3 .

MEASUREMENTS. Length (in mm). Body: ♂ 12, ♀ 12.5; body with wings: ♂

15, ♀ 17; pronotum: ♂ 2, ♀ 2.1; visible parts of tegmina: ♂ 11, ♀ 13; hind femora:

♂ 13, ♀ 14; ovipositor 12.2.

COMPARISON. The new species is clearly distinguished from the other species of this subgenus by the characteristic shape of ventral branch of median sclerite in the male genitalia as well as by the presence of additional lateral sclerotizations in these genitalia.

ETYMOLOGY. This new species is named after Malaysia where it was collected.
