ETYMOLOGY. — Species named after its pattern of coloration.

DIAGNOSIS. — Within the genus, species close to Luzaridella clara Desutter-Grandcolas, 1992 by its light coloration ( Fig. 11 ), its small and globular male genitalia, and the shape of female copulatory papilla (rectangular and entirely sclerotized); it can be separated from this species by its coloration and length of ovipositor (less than 10 mm in L. clara , i.e., well shorter than FIII and TIII, versus> 13 mm in L. maculata n. sp., longer than TIII).

Also resembling Luzaridella miniata n. sp. by general coloration, but differing from that species by sternite coloration (light brown marked with black), male stridulatory file (16 teeth against five in L. miniata n. sp.), male genitalia (compare Figs 7 D-G and 11E-G), female genitalia (oval and partly desclerotized dorsally and ventrally in L. miniata n. sp.), and a smaller size (compare Tables 5 and 6).

DESCRIPTION

In addition to the character of the genus (see Desutter-Grandcolas 1992a).

General morphology

TIII serrulation lacking between subapical spurs and apical spurs on both sides; on inner side, three to five spines (mean 3.8) in males, four to six spines (mean 4.9) in females between isa1 and isa2, four to five spines (mean 4.1) in males, four to six spines (mean 4.8) in females between isa2 and isa3, four to six spines (mean 4.5) in males, four to five spines (mean 4.9) in females between isa3 and isa4, 9-14 spines (mean 11.8) in males, 13-15 spines (mean 14.4) in females above isa4; on outer side, two to four spines (mean 3) in males, three to four spines (mean 3.4) in females between osa1 and osa2, four to five spines (mean 4.3) in males, five spines in females between osa2 and osa3, four to five spines (mean 4.4) in males, four to six spines (mean 5) in females between osa3 and osa4, 9-13 spines (mean 10.6) in males, 12-14 spines (mean 13.1) in females above osa4. Barsitarsomere III serrulation: five to nine inner spines (mean 8.6 in males, 7.8 in females) and five to nine outer spines (mean 5.8 in males, 7.5 in females) in addition to apical spines.

Phalangopsidae crickets from the Mitaraka

Coloration

Face yellowish with light brown marks, including a curved line between lower angle of eyes and epistomal suture and sometimes a light yellow, median longitudinal line under median ocellus ( Fig. 11D ); clypeus and labrum light yellow, with a pair of brown spots on clypeus; cheeks light to dark brown with an elongate yellowish spot close to the eye more or less prolonged toward mandibula; ocelli partly circled with black. Fastigium and vertex light to dark brown, fastigium sometimes lighter; with five longitudinal yellow lines: two external ones from lateral ocelli to occiput, sometimes forked behind the eyes, extending to pronotum and forewings ( Fig. 11A, C ); two inner ones, transparent, shorter than external stripes, joining at vertex mid length; one median and longitudinal, very thin, short and most often barely visible. Scapes yellow marked with brown, especially at base and apex. Antennae yellow at base, then brown with yellow rings. Palpi light brown laterally, lighter on dorsal and ventral margins ( Fig. 11C, D ). Pronotum DD and LL separated by a wide yellow stripe ( Fig. 11C ); DD light brown with lighter muscular inscriptions; posterior margin largely bordered with black brown, except for two yellow spots close to longitudinal yellow stripes; LL light brown to yellow on lower margin, with a wide black brown band dorsally. Legs ( Fig. 11A ): FI and FII yellow with two brown rings. TI and TII brown with two and three yellow rings, respectively. Basitarsomeres I and II brown, yellow at base; tarsomeres 2 and 3 yellow. FIII yellow with brown pattern: outer side and inner base striped with brown; a brown ring near the knee; knee brown. TIII ( Fig. 11A ) brown dorsally, lighter ventrally; near the knee, a short black ring and a larger yellow ring; an additional yellow fleck on each side, more or less distinct; spurs yellowish, their base and apex dark. Basitarsomeres III light brown with darker spot near apex; tarsomeres 2 and 3 yellowish.Tergites light brown with dark brown and yellow pattern ( Fig. 11B ). Sternites light brown marked with black. Cerci light brown, lighter at base with yellow ring near apex.

Male

Metanotum glandular, with a wide bunch of long setae along both anterior and posterior margins, separated by a deep transverse furrow. FWs ( Fig. 11A ) as wide as pronotum and abdomen, reaching tergite 4. Venation visible but sometimes interrupted; lateral field with five parallel longitudinal veins; stridulum complete, harp without vein, mirror much wider than long, not crossed by any vein; stridulatory file with 16 teeth. Subgenital plate short and high.

Male genitalia ( Fig. 11 E-H)

Very small and globular, with relatively long and thin rami. Pseudepiphallic arms less than half rami length. Dorsal membrane of pseudepiphallus (between arms) present as a small, broadly triangular area, with relatively big apical structures; B-sclerite short, wide over its whole length, not narrowed distally; A-sclerite with a very small apical spine. Pseudepiphallic parameres globular with a non-protruding, small, broad apical tooth. Ectophallic apodemes not extending beyond rami anterior tip; very wide and concave along their whole length, regularly narrowed anteriorly; arc fully sclerotized, narrow compared to ectophallic apodemes. Ectophallic fold very short, sclerotized. Endophallic sclerite with trifid distal margin. Endophallic apodeme very well developed, with a high median longitudinal crest, connected to ectophallic fold, and lamellas along and beyond endophallic sclerite. No dorsal cavity.

Female

Larger than male. FWs short, little recovering, reaching tergite 1 ( Fig. 11B ). Dorsal field with six to eight longitudinal veins, lateral field with four longitudinal veins. Subgenital plate distal margin deeply sinuate. Ovipositor as long or slightly longer than FIII, but longer than TIII.

Female genitalia

Copulatory papilla ( Fig. 9 F-H) entirely sclerotized and short, less than one millimetre long; almost rectangular in shape; upper part with small protuberance.

Measurements (in mm)

See Table 6.

Variation

Vertex sometimes brown ferruginous. In darker specimens, tergite coloration sometimes dark brown. In males veins 3 and 4 on FW lateral field sometimes extended near FW lower margin. Some specimens at hand seem in bad condition and present very dark coloration for cheek (light coloration barely visible), vertex (yellow forks sometimes difficult to see), scapes (entirely brownish), base of antennae (brown), palpi (uniform coloration), pronotum (yellow spots not visible), sternites (coloration very variable with black margins or middle part), or metanotum (light brown to yellowish).
