Megadiestramima (Neodiestramima) orlovi khmerica View in CoL subsp. nov.

( Figs 69, 70)

Holotype. Male , Cambodia, southern part of Elefan Mts , Phnom-Bokor Mt, Bokor National Park, 700–1000 m, on small road in primary forest, at night, 15–17.IX.2003, A. Gorochov, L. Anisyutkin ( ZIN).

Paratypes. One male, 2 females, same data as for holotype ( ZIN) ; 5 males, 1 female, same data but 18– 22.IX.2003, A. Gorochov, M. Berezin ( ZIN) ; 1 male, 1 female, same country, but northern part of Elefan Mts , Kiri-Rom National Park in 130 km NNE of Sihanoukville Town, 300–500 m, secondary forest, on forest floor at night, 27.IX–1.X.2003, A. Gorochov, M. Berezin ( ZIN) ; 1 female, same park ( Kiri-Rom ) in 150 km NNE of Sihanoukville Town, 600–800 m, secondary forest, 7–10.X.2003, A. Gorochov, M. Berezin ( ZIN) .

Description. Male (holotype). General appearance (including structure of body) as in M. (N.) o. lata but with some differences: colouration lighter (generally light brown, almost as in M. o. orlovi ) and with a few small brown marks on anterior and dorsal parts of epicranium, barely darkened pronotum and most part of mesonotum, a few small brown spots on other tergites along their posterior edges (but 7–10th abdominal tergites more uniform), and almost completely light fore and middle legs as well as hind tibia and tarsus (but apical parts of all femora darkened almost as in both previous subspecies); posteromedian process of seventh abdominal tergite with narrower proximal part (almost as in M. o. orlovi ) and small apical notch ( Fig. 69); ratio of lengths of this process and paraproct similar to that of M. (N.) o. lata.

Variations. Colouration slightly variable: sometimes almost without darkened marks on head, tergites and most part of hind femur. Posteromedian spine of seventh abdominal tergite with apex often truncate but sometimes even rounded.

Female. Colouration and structure of body as in males; however, structure of abdominal apex (including ovipositor) as in M. (N.) o. lata with differences only in shape of apex of posteromedian spine of seventh abdominal tergite which usually notched (but sometimes truncate), and in shape of genital plate having distinctly narrower apical part (see Figs 70 and 73).

Length in mm. Body: male 22–26, female 24– 28; pronotum: male 7.5–8, female 8–8.7; fore femur: male 18–21, female 18–20; hind femur: male 33–38, female 34–37; hind tibia: male 37–42, female 38–43; hind basitarsus: male 6.5–7.2, female 6.3–7; ovipositor 19–21.

Comparison. Differences of this subspecies from two other ones are also given in the key above.

Etymology. This species is named after the Khmer people, the main nationality of Cambodia.
