60 Natura Somogyiensis ately deeply and not uniformly punctured with small punctures, shiny, interspaces about 0. 2-0.8x as large as a puncture. Postoccipital carina complete. OOL : POL : OCL: 6 : 2 : 5. Postocellar area wider than long as 5:9. Ratios of antennal segments: 12 : 7 : 29 : 21:19:13:13:12:12. Supraantennal tubercles and antennal crests confluent, supraan- tennal tubercles slightly developed. Antenna about as long as head and half of thorax (till mesoscutellum) combined. Gena about 0.7x as wide as diameter of anterior ocellus. Clypeal emargination about 0.33x as deep as clypeal median length. Mesonotum very densely, minutely, uniformly and moderately deeply punctured, moderately shiny. Mesoscutellum densely and moderately deeply punctured with minute punctures, shiny. Mesoscutellar appendage with sporadic, moderately small, deep punctures, shiny. Metascutellum with moderately large, shallow punctures, shiny. Mesopleuron densely punctured with minute, moderately deep punctures, moderately shiny. Mesoscutellum bluntly elevated, mesopleuron strongly, subpiramidally elevated. Mesostemum without thorn. Abdomen from tergite 2 with fine microstriation, shiny. Length of hind basitarsus : length of inner hind tibial spur: 45 : 21. Hind basitarsus as long as next 3 tarsal seg­ments combined. Length: 9.7 mm. The new species is related to Tenthredo danbanica Wei & Niu, 2009, however, T. danbanica has only a frontal spot, scape and pedicell are yellow, third tergite is domi­nantly black. In the new species, head, except hind orbit, is black and also scape and pedicell are black, third tergite with wide yellow band. The other relative is Tenthredo brachycera (Mocsáry, 1909), however, in T. brachyc- era (and its relatives) the 4th tergite is yellow, not the 3rd as in the new species. Furthermore, in T. brachycera, the mesostemum black but entirely pale in the new spe­cies. Tenthredo rubropedicella spec. nov. (Fig. 18) Holotype: female, China, Kansu men, Xiahe (Labrang), 3300-3700 m., 01-15. 06. 1998, V. Major leg. Paratype: topotypic. Antenna black, only pedicell (2nd segment) ferruginous (scape and antennal flagellum entirely black). Head black; yellow: clypeus, labrum, mandibles (except brown apex) and palpi yellowish white. Thorax entirely black (only cenchri pale). All coxae, trochant­ers and femora black. Tibiae reddish yellow, anterior 4 tibiae with apical small black spot, hind tibiae with wider black apical ring. Tarsi reddish yellow. Wings hyaline; stigma, apical third of costa, subcosta and veins black. Basal 2/3 of costa yellow. Abdomen black, 3rd tergite yellow with large anterior semicircular black area. Tergite 4 with 2 yellow lateral spots. Tergite and stemite 7 yellow with black anterior margine. Tergite 10 yellow. Stemites 3 and 4 with large central yellow spot on hind margin. Ovipositor black. OOL : POL : OCL: 22 : 5 : 10. Postocellar area wider than long as 2 : 1. Ratios of antennal segments:14 : 8 : 30 : 17 : 16 : 13 : 12 : 11 : 11. Antenna about as long as head and half of thorax combined. Total area of head very densely punctured with small but rough, moderately deep punctures, matt. Supraantennal tubercles slightly developed and confluent with frontal crest. Postoccipital carina complete. Gena about 0.9x as wide as diameter of anterior ocellus. Clypeal emargination about 0.25x as deep as clypeal median length. Mesonotal lobes and mesoscutellum densely granulated, matt. Mesoscutellar appendage, densely, roughly punctured with moderately deep and moder­ately large punctures, moderately shiny. Metascutellum, densely, moderately deeply
