Diagnosis. -
This species is distinguished from other species of Amblyrhethus by the following characters: male forewings vein A1 not connected to A2; metanotum with two clusters of bristles on the middle; first abdominal tergite with two rounded projections close to anterior margin. Male genitalia: pseudepiphallic sclerite somewhat enlarged on anterior half, especially at the middle level, rounded in dorsal and ventral views; PsP clavate, EctAp slightly curved inwards in the middle, both in dorsal and ventral views. Copulatory papilla tapered, with two anterior projections.
Description. -
Head: Fastigium wide, with bristles laterally (Fig. 5E View Figure 5 ). Three ocelli present, aligned in frontal view (Fig. 5E View Figure 5 ); lateral ocelli rounded, median ocellus elliptical, smaller than lateral ones; frons smooth (Fig. 5E View Figure 5 ). Antennal scape longer than wide, narrower than fastigium in frontal view. Maxillary palpi article 3 the longest, 4 and 5 almost same-sized; article 5 straight (Fig. 5B, D View Figure 5 ). Thorax: Dorsal disk wider than long, covered by fine pubescence (Fig. 5A, C View Figure 5 ). Dorsal disk cephalic margin slightly concave, caudal margin convex (Fig. 5A, C View Figure 5 ). Lateral lobes ventro-cephalic and ventro-caudal angles rounded (Fig. 5B, D View Figure 5 ). Forewings covering abdomen, hindwings slightly longer than forewings (Fig. 5A-D View Figure 5 ). Legs: TI with tympana present on inner and outer faces; three apical spurs, two ventral, one dorsal. TII with four apical spurs, two ventral, two dorsal. TIII subapical spurs 5/4, with two spines between each spur, except proximal spurs with three spines; eight spines above subapical spurs on inner and outer sides. FIII longer than TIII (Fig. 5B, D View Figure 5 ). TIII inner apical spurs: iad>iam>iav; outer apical spurs: oam>oav>oad. Basitarsus dorsal spines 3/1; inner apical spur slightly longer than outer apical spur.
Male. Forewings slightly shorter than hindwings; anal area slightly bulged dorsally (Fig. 5B View Figure 5 ), A1 not connected to A2. Stridulatory vein (PCu vein) present, portion close to CuPa sinuous. Harp crossed by four veins connected to CuPa; first and second harp veins shorter than third and fourth; third and fourth harp veins connected in the proximal region. Mirror as wide as long, divided in the middle by a curved vein. Apical field longer than mirror; lateral field with 13 diagonal veins (Fig. 5F View Figure 5 ). Metanotum with two clusters of bristles on the middle, first abdominal tergite with two rounded projections close to anterior margin (Fig. 5G View Figure 5 ). Supra-anal plate posterior margin rounded (Fig. 5H View Figure 5 ); subgenital plate longer than wide, posterior margin convex (Fig. 5I View Figure 5 ).
Male genitalia: (Fig. 6 View Figure 6 ) Pseudepiphallus: pseudepiphallic sclerite trapezoidal in dorsal and ventral views, anterior half inflated; slightly curved upwards in lateral view; anterior margin rounded on median region (Fig. 6A View Figure 6 ). LLophi curved upwards, posterior margin sub-straight in dorsal and ventral views; ventral face translucent (Fig. 6A, B View Figure 6 ). PsP clavate, longer than LLophi, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views, inner margin with anterior projection finger-shaped (Fig. 6A, B View Figure 6 ). Rami straight in dorsal and ventral views, two times longer than pseudepiphallic sclerite (Fig. 6A-C View Figure 6 ). Ectophallic invagination: EctF strongly sclerotized, shorter than PsP, trapezoidal on the edge of posterior margin of pseudepiphallic sclerite (Fig. 6A-D View Figure 6 ). EctAp longer than pseudepiphallic sclerite, slightly curved inwards in the middle in dorsal and ventral views (Fig. 6A, B View Figure 6 ); arc not complete, curved posteriorly; ventral projections of ectophallic invagination shorter than arc. Endophallus: End short, u-shaped, in the middle of pseudepiphallic sclerite (Fig. 6B View Figure 6 ).
Female. Larger than male, similar coloration (Fig. 5C, D View Figure 5 ). Forewings with longitudinal veins crossed by accessory veins. Subgenital plate wider than long, posterior margin concave (Fig. 5J View Figure 5 ). Ovipositor slightly inclined upwards; apex of ovipositor lateral margins serrulate, posterior margin truncate (Fig. 5C, J View Figure 5 ). Copulatory papilla bell-shaped, with two posterior thin projections directed ventrally (Fig. 6E-G View Figure 6 ).
Coloration. -
Occiput, vertex, and pronotum general coloration reddish brown (Fig. 5A-D View Figure 5 ). Face reddish-brown to medium brown (Fig. 5E View Figure 5 ); antennal scape medium brown; antennomeres yellowish with some isolated antennomeres medium brown (Fig. 5A-D View Figure 5 ). Forewings slightly translucent, medium brown. Metanotum light brown (Fig. 5G View Figure 5 ), first three abdominal tergites medium brown, the other tergites dark brown. Supra-anal plate dark brown (Fig. 5H View Figure 5 ). Abdominal sternites yellowish brown; subgenital plate medium brown (Fig. 5I View Figure 5 ). FI, FII, TI, and TII medium brown to reddish brown. FIII reddish brown, slightly striped, distal margin darker; TIII medium brown; spurs yellow with apex dark brown; tarsomeres yellowish-brown (Fig. 5C View Figure 5 ).
