Haris A.: A new Athlophorus Burmeister, 1847 species from Cambodia (Hymenoptera: Tenthredinidae)

66 Natura Somogyiensis Description of the new species Athlophorus kongensis spec. nov. (Figs. 1 and 2) Holotype: male: SW. Cambodia,20 km SE of Koh Kong, 11° 37' N 103° 07’ E, 50-300 m, May 2005, Jendek and Sausa lg. Head black; white: labrum, clypeus, wide inner orbits, small triangular supraclypeal spot (yellowish white). Antenna black, scape and pedicell white. Thorax black; white: wide hind margin of pronotum, tegula, parapteron, large oval longitudinal spot from parapteron down to mesepietemal-mesostemal border, mesoscutellar appendage, cenchri. Legs black; white: all trochanters, anterior tibia entirely, middle tibia except narrow apical ring and basal third of hind tibia; all trochanters, anterior tibia entirely, middle tibia except narrow apical ring and basal third of hind tibia. Wings hyaline, both radial cells entirely infuscate, infuscation not overprolonged basal part of sitgma. Upper half of all cubital cells infuscated either. Stigma transparent light brown, costa, subcosta, venation dark brown. Abdomen black: white: narrow base of propodeum, 2nd and 3rd tergites except large pairs of middle central black spot, wide basal and narrow hind mar­gin of tergite 4 and basal four sternites. Ratios of antennal segments: 9 : 7 : 22 : 19 : 15 : 9 : 9 : 9 : 8. Antenna about as long as head and thorax combined without propodeum. OOL : POL : OCL: 13:4:15. Frontal area very densely, moderately deeply punctured with small punctures, moderately shiny. Other parts of head smooth and shiny. Head moderately contracted behind eyes. Frontal area marked by bluntly elevated ridges. Clypeus roundly emarginated. Clypeal emargination about 0.33x as deep as clypeal median length. Postoccipital carina reaching up to 2/3 of hind orbit. Gena nearly linear, about 0.3x as wide as diameter of anterior ocellus. Anterior lobes of mesonotum, mes- oscutellum and mesoscutellar appendage densely, moderately deeply punctured with moderately small punctures, moderately shiny. Lateral lobe smooth and shiny outside, moderately densely and deeply punctured inside, moderately shiny. Upper anterior and upper midie part of mesopleuron with large and deep punctures, hardly shiny. Mesostemum smooth and shiny. Mesoscutellum flat without carina or pyramidal eleva­tion. Abdominal tergites shiny with fine surface sculpture. Claw with strong subapical tooth hardly shorter than apical, basal lobe not visible. Length: 6.7 mm. The new species is closely related to Athlophorus meghalayensis Saini and Singh, 1987. The differences: in A. meghalayensis clypeus and mesopleuron and dominantly tibiae (except anterior) black. These parts in the new species entirely or dominantly white as it is written above in the description. Larger, 9.5 mm, the new species is only 6.7 mm. Penis valves are also different, see Fig. 28 in Saini and Vasu and Fig. 86a in Saini 2006 and compare with Fig. 2. Penis valve resembles most to that of Athlophorus gracilis gracilis (Konow, 1898). (Fig. 86 in Saini see also Fig. 3.) the differences see in Fig. 2 and Fig. 3. Furthermore, Athlophorus gracilis gracilis Konow and other 2 related species Athlophorus gracilis orbitalis Konow, 1906 and Athlophorus graciliodes Malaise, 1947 has clypeus, labrum, mesopleuron, mesepistemum black. These parts in the new species are entirely or dominantly white.
