MATERIAL. Holotype – ♀, Thailand: Phetchaburi Prov., 50 km SW of Phetchaburi

Town, environs of Kaeng Krachan National Park, ~ 400 m, secondary forest near reservoir,

2–5.VIII 1996, A. Gorochov ( ZIN). Paratype –same data as for holotype, but 30.VII–1.VIII

1996, ♀ ( ZIN) .

DESCRIPTION. Female (holotype). General appearance approximately as in female of

A. (E.) namlik but with some characteristic features: coloration almost uniformly light brown with slightly darker (greyish brown) median triangle on anterior surface of epicranium, small brown marks on antennal cavities and scapes as well as on dorsal parts of all tibiae, darkish thin reticular pattern on dorsal half of middle femur and on dorsal and lateral surfaces of hind femur, almost yellowish body venter (however, genital plate and ovipositor light brown and reddish brown, respectively), and numerous whitish dots on abdominal tergites; rostral tubercle almost conical, reaching apices of scapes; lateral lobes of pronotum also similar to those of A. (E.) namlik but with almost straight ventral edges (except for humeral notch in posterior part) and with short hind lobe having distinctly concave posterior edge; tegmina very small, elongately oval, lateral, partly covered with pronotum (hind pronotal lobe reaching middle part of tegmina); abdominal apex very similar to that of A. (E.) bangkirai , but genital plate longer, narrowing to moderately narrow apex having a pair of long posterolateral spines as well as rather wide and roundly angular notch between them ( Fig. 91 ); ovipositor as in

Fig. 182 .

Variations. Second female slightly darker, i.e. with pronotum and light part of epicranium having numerous very small darkish marks, with metanotum and abdominal tergites greyish brown, and with apical parts of all femora clearly darkened.

(Anelytra) semicurvata sp. n.; 150 – A. (Anelytra) archaica sp. n.; 151, 152 – A. (Anelytra)

forceps sp. n.; 153, 154 – A. (Stenanelytra) busuanga sp. n.; 155 – A. (Stenanelytra) nigra nigra (Ingr.) . Genital sclerites from above (134, 135, 137, 139, 141, 143, 145, 147, 148, 151,

153, 155) and from side (136, 138, 140, 142, 144, 146, 149, 152, 154); right genital sclerite from above (150).

Male unknown.

MEASUREMENTS. Length (in mm). Body 23–24; pronotum 7–7.3; hind pronotal lobe

1–1.1; visible parts of tegmina 0.8–1.2; hind femora 13.2–14; ovipositor 11.3–11.7.

COMPARISON. The new species is more or less similar to A. (A.) robusta , A. (A.)

eunigrifrons, A. (A.) fastigata , A. (A.) elongata, A. (E.) indigena , A. (E.) parasignata , A. (? E.)

laotica and A. (Perianelytra) propria in the presence of a pair of long (but not very long)

posterolateral spines on the apical part of female genital plate. However, A. (A.) elongata has the posteromedian notch of female genital plate clearly wider and shallower, A. (E.) indigena has this notch distinctly larger (deeper and wider), A. (? E.) laotica has this notch narrower,

deeper and more angular, and the other species from this list have the anterior epicranial surface with a large very dark area absent in A. (? E.) phetchaburi . From the other congeners,

the new species differs in the same characters of coloration in combination with the abovementioned peculiarities of female genital plate.

ETYMOLOGY. The new species is named after the Phetchaburi Province of Thailand where it was collected.
