ETYMOLOGY. — Species named after its slender shape compared to other species of the genus.

DIAGNOSIS. — Within the genus, species relatively large, with thin PIII at least in males ( Fig. 7A ). Male FWs relatively soft, compared to other species of the genus, covering abdomen up to tergite 7; stridulum complete. Male genitalia distinctive (A-sclerite protruding as a thick curved spine; pseudepiphallic apical sclerotization X-shaped, delimiting a pair of distal cavities very lightly sclerotized dorsally, and a free sclerotized process more ventrally; distal twothird of ectophallic apodemes rubbon-like and thin, curved ventrally toward pseudepiphallic parameres, anterior third vertical). Female copulatory papilla oval, with dorsal and ventral sides little sclerotized. Species differing from Luzaridella maculata n. sp. by male and female genitalia (compare Fig. 7 D-G and Fig. 11 E-G), male stridulatory file, a bigger size (compare Table 5 and 6) and sternite coloration (light brown with median part darker). More similar to Luzaridella annulata Desutter-Grandcolas,1992 from which it can be separated by its larger size, darker coloration (especially for annulated legs), and female copulatory papilla (compare Fig. 9 C-E and Desutter-Grandcolas 1992a, figure 9).

DESCRIPTION

In addition to characters of the genus (Desutter-Grandcolas 1992a):

General morphology

TIII serrulation lacking between subapical spurs and apical spurs on both sides; on inner side, two to four spines (mean 2.5 in male, 3.5 in females) between isa1 and isa2, two to four (mean 2.5 in male, 3.3 in females) spines between isa2 and isa3, three to four spines (mean 4 in male, 3.8 in females) between isa3 and isa4, 12-13 spines in male (mean 12.5) and 11-15 spines (mean 13.5) in females above isa4; on outer side, three to four spines (mean 3 in male, 3.3 in females) between osa1 and osa2, three to four spines (mean 3 in male, 3.5 in females) between osa2 and osa3, four to six spines (mean 4 in male, 5.3 in females) between osa3 and osa4, 11-12 spines (mean 11.5) in male, and 12-13 (mean 12.5) spines in females above osa4. Basitarsomere III serrulation: six to seven inner spines (mean 6.5 in male, 6.8 in females), six to nine outer spines (mean 6.5 in male, 7.3 in females) in addition to apical spines.

Coloration

Head: Face light brown marked with yellow; cheeks darker than face; ocelli marked with black; vertex and occiput dark brown, with four longitudinal yellow lines ( Fig. 8A ): two outer lines starting at median ocellus, reaching lateral ocelli, forked at beginning of vertex, and extending to pronotum; two inner lines, shorter than outer stripes. Eyes grey. Antennal pits whitish. Scapes yellow with two brown rings, one at base, one at apex. Antennae yellow at base, then brown with yellow rings. Mouthparts white with light brown spots. Palpi light brown, white on their dorsal and ventral sides. Pronotum DD and LL separated by a wide yellow stripe ( Fig. 8A, B ); DD light brown with lighter muscular inscriptions and two yellow spots (close to yellow stripes) on posterior margin; LL ferruginous brown, light brown to yellow close to anterior angle. Legs: FI and FII yellow with three brown rings. TI and TII brown with two and three yellow rings, respectively. Tarsomeres I and II brown, yellow at their base. FIII yellow with brown pattern: outer side and inner base striped with brown; a brown ring near apex; apex brown. TIII brown on dorsal side, lighter on ventral side; with two yellow rings barely visible; spurs yellowish, their base and apex dark; tarsomeres III light brown. Tergites light brown with dark brown and yellow pattern ( Fig. 8C ). Sternites light brown with a darker median part. Cerci light brown, with a brown ring close to brown apex.

Male

Metanotum glandular, covered with many long setae ( Fig. 7C ). Forewings ( Fig. 7B ) wider than pronotum and abdomen, trapezoidal (wider posteriorly than anteriorly); long for the genus, reaching tergite 7. Venation faint ( Fig. 9A, B ); lateral field with four parallel longitudinal veins, the second branched distally; stridulum complete, harp without vein, mirror much wider than long, not crossed by any vein; PCu very oblique, bearing a very short file located very high on the vein and with only five teeth.

Male genitalia ( Fig. 7 D-G)

Genitalia slightly wider than long, with very short rami ( Fig. 7D ). Pseudepiphallic arms well-developed; membrane separating them sclerotized apically as two cup-like sclerites connected together and extending toward sclerotized parts of EEI and ectophallic fold as a pair of free sclerotized processes ( Fig. 7D, G ); A-sclerite hook-like; B-sclerite ( Fig. 7F ) widened before apex, then regularly narrowed toward acute apex; pseudepiphallc parameres simple, not hook-like, between pseudepiphallic apical sclerites and A-sclerites ( Fig. 7D, E, G ). Ectophallic apodemes thin and rubbon-like on anterior twothird, as a curved, vertical lamella on posterior third ( Fig. 7D ); arc fully sclerotized, sinuous ( Fig. 7D ); pseudepiphallic sclerite anterior part vertical, abutting against ectophallic apodeme ( Fig. 7D ). Ectophallic fold short, with a trifid apical sclerite ( Fig. 7E ). Endophallic sclerite very short, distal apex trifid ( Fig. 7E ); endophallic apodeme very short, lamella-like. No dorsal cavity.

Female

Larger than male. FWs short, not overlapping, reaching tergite 3. Dorsal field with seven to nine longitudinal veins, lateral field with four or five longitudinal veins.

Female genitalia

Copulatory papilla ( Fig. 9 C-E) small (less than 1 mm long), nearly oval in shape, distal margin bisinuate, ventral and dorsal sides less sclerotized.

Measurements (in mm)

See Table 5.

Variation

Size highly variable in females. First ring of FI and FII sometimes hardly marked.Dorsal disc and tergites sometimes darker.
