Haris A.: New Tenthredo Linné, 1758 species from China (Hymenoptera, Tenthredinidae)

Haris, A.: New Tenthredo Linné, 1758 species from China 57 Legs entirely yellow. Wings hyaline, costa and stigma pale yellow, venation brown. Head, including temple and vertex deeply and roughly punctured, shiny, around frontal area densely wrinkled. Postoccipital carina complete and well developed. Ratios of antennal segments: 10 : 5 : 22 : 15 : 15 : 13 : 10 : 10 : 10. Antenna short and relatively thick, as long as head head and thorax without propodeum combined. OOL : POL : OCL: 14 : 5 : 10. Postocellar area wider than long as 1 : 1.6. Clypeus roundly emarginated. Clypeal emargination about 0.33x as deep as clypeal median length. Gena 1.2x as wide as diameter of anterior ocellus. Supraantennal tubercles confluent with antennal crest, normally, not strongly, developed. Mesonotal libes with minute, moderately deep and very dense punctures, moderately shiny. Mesoscutellum with moderately large, deep, dense punctures, moderately shiny. Mesoscutellar appendage with large, deep and dense punctures, modertely shiny. Metascutellum nearly smooth and shiny with few deep punctures. Mesopleuron densely punctured with moderately deep, moderately small punctures, also wrinkled, herdly shiny. Mesopleuron strongly elevated. Mesoscutellum bluntly, subpiremidally elevated with blunt horisontal carinas. Head and abdomen with moderately dense, short, white pubescence. Propodeum shiny with very fine sutface sculpture. Other tergites hardly shiny with microstriation. Length of inner hind tibial spur : length of hind basitarsus: 17 : 4L Hind basitarsus hardly shorter than next 3 seg­ments combined as 41 : 45. SUbapical tooth of claws hardly shorter than apical. Length: 8.7 mm. The new species is dedicated to Dr. Levente Ábrahám. The very closest relative of the new species is Tenthredo grombczewskii (Jakowlew, 1891). The differences: scapus and pedicell are entirely yellow in the new species (they are black in T. grombczewskii), the new species much smaller (8.7 mm versus 13-14 mm) and legs completely yellow (dorsal side of all femora and line of anterior tibia black in T. grombczewskii). Gena of Tenthredo grombczewskii very elongated, 2.5x as long as diameter of anterior ocellus, in the new species gena subequal with the diameter of ante­rior ocellus (see the description above). Other related species: Tenthredo brevipilosila Wei, 2002, large, 15 mm species (the new species is only 8.7 mm), antenna long (short in the new species) and legs richly decorated with balek (entirely yellow in the new species). Tenthredo brevipilosila Wei, 2002 is closely related to T. shenisensis. Tenthredo nigrobasalis Malaise, 1945 has tergite 1 and 2 black, other tergites red, otherwise completely different from the new species having legs are richly coloured with black, and head and thorax black. Tenthredo sinomirabilis spec. nov. (Fig. 15) Holotype: female, China, Shaanxi, Qinling mts. Xunyangba (6 km E), 1000-1300 m., 23. 05.- 13. 06. 1998, leg. I. H. Marshal Head and antenna black; white: mandible (except apex), labrum, clypeus, palpi and blurred spot on lower third of outer orbit. Thorax black; white: wide hind margin of pronotum, tegula, large elongate spot on mesopluron, vertical broad band on katepimeron, most of metepistemum. Legs white; black: hind femur, dorsal side of middle femur, dorsal line of anterior femur, small apical spot of anterior and middle tibiae, apex and dorsal line on hind tibia. Wings subhyaline, apical third gently brown infuscate. Stigma black with wide lower yellow transparent margin, costa, subcosta and veins black.
