MATERIAL. Holotype – ♂, Cambodia: northern part of Elephant Mts, Kiri-Rom National Park (~ 130 km NNE of Sihanoukville Town ), 300–500 m, secondary forest, 27.IX–

1.X 2003, A. Gorochov, M. Berezin ( ZIN).

DESCRIPTION. Male. Body slightly longer than in all previous congeners described here and rather small for this genus. Coloration (Figs 54, 55) light brown with dark brown lower half of rostral tubercle, most part of antennal cavities, area between them, median stripe under this area and small areas under eyes (near them), brown large area between above-mentioned stripe and clypeus, medial parts of scapes and two spots on dorsal half of fore tibia (one near distal edges of tympana and one near apical part), slightly lighter (almost greyish brown) small marks on fore tibia near proximal edges of tympana and on dorsal half of middle tibia as well as some membranes between venation in laterodistal parts of tegmina,

yellowish mouthparts (except for light brown clypeus and mandibles) and venter of rest part of body, and numerous whitish dots on abdominal tergites. Head also rather long and narrow

(Fig. 55); pronotum with lateral lobes slightly lower than in previous congeners and having ventral edges almost as in A. (E.) namlik , and with hind lobe covering only small basal parts of tegmina; tegmina reaching second abdominal tergite, with stridulatory areas visible from above, and with distal parts roundly angular (Fig. 54); last tergite with short posterodorsal lobe having moderately small posteromedian notch and almost obtusely angular projections around it ( Fig. 97 ); cercus similar to that of Perianelytra in shape but with medial (dorsal)

spine located slightly more proximally ( Figs 97–99 ); epiproct small and simple, widely triangular ( Fig. 100 ); each paraproct with short and rounded apical lobule; genital plate with moderately deep and roundly angular notch between normal styles ( Fig. 97 ); genitalia with very small and rather simple right sclerite (left one missing) having ventroproximal lobule directed forwards and medially (i.e. not curved laterally; Figs 150 , 170 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 23; pronotum 6.2; hind pronotal lobe 0.9;

visible parts of tegmina 3.4; hind femora 10.

COMPARISON. The new species is similar to the subgenus Perianelytra and some species of the subgenus Euanelytra ( A. malaya and A. boku ) in the primitive structure of male cerci. However, the medial (proximal) spine of these cerci is somewhat moved to the cercal base in A. (A.) archaica and to the cercal apex in A. (E.) malaya and A. (E.) boku ; thus,

these three species may belong to two subgenera ( Anelytra s. str. and Euanelytra ) or to a certain separate subgenus related to Perianelytra but having unspecialized male epiproct.

The latter opinion might be supported by the absence of distinct ventroproximal lobules on the genital sclerites in Perianelytra ( Fig. 174 ), A. (E.) malaya and A. (E.) boku ; but A. (A.)

archaica differs from them by the presence of such lobules ( Fig. 170 ) that is characteristic for majority of the other species of Anelytra s. l. So, A. (E.) malaya and A. (E.) boku simply could lose these lobules.

ETYMOLOGY. Name of the new species is the Latinized Greek word “archaica” (ancient,

very old) given in connection with the primitive structure of male cerci.
