Tenhtredo cylindriformis sp. n. Female. Head mainly light brown. White: labrum, clypeus, scape, pedicely, palpi, narrow inner orbit, outer orbit, gena, head behind its hind occipital carina. Black: apices of mandibles, two corner-like patterns from the lateral ocelli turning back at the inner orbits to the occipital carina, supraantennal grooves and a little spot above antennae. Head and thorax densely covered with short yellowish pubescence, about 1/4 times as long as the diameter of front ocellus on the head and 2/3 times as long as the diameter of front ocellus on the mesonotum. Vertex and temples shining, moderately deeply and densely punctured with shining interspaces about as large as the diameter of a puncture. Head widened behind the eyes, hind margin moderately deeply emarginated with occipital carina. Clypeus roundly and shallowly emarginated, emargination about 0.2 times as long as median length. OOL : POL : OCL = 3.2 : 1.0 : 3.2. Antenna/costa - 53/75. Proportions of the lengths of antennái segments: 3rd 43: 4th 28: 5th 23: 6th 19: 7th 18: 8thl6: 9th 15. Pronotum, propleuron, prostemum, tegulae white, pronotum and propleuron with narrow black line. Front lobes of mesonotum light brown with black rectangular spot at their fore margin. Lateral mesonotal lobes brown, each with larger and smaller elliptic black spot. The larger spots cover the major part of lateral lobes. Lateral steep sides of mesonotal lobes white. Mesonotum extremely densely and finely punctured, nearly dull. Pronotum and propleuron punctured as mesonotum but little more shining. Mesopostnotum white with black spot below mesoscutellar appendage and with further two smaller spots around each cenchrus. Mesoscutellar appendage and metascutellum connected with white longitudinal keel. Scutellum, mesoscutellar appendage white, scutellum with black hind margin. Mesoscutellum pyramidally raised with longitudinal median keel, moderately roughly and moderately deeply punctured, shining, with interspaces about 1-3 times as large as a puncture. Pubescence of mesonotum long and white and about as long as the diameter of front ocellus. Mesoscutellar appendage shining, with 18 smaller or larger moderately deep punctures, some of them very large and connected to each other. Metascutellum brown, shining, with sporadic minute punctures. Cenchri light brownish white. Mesopleuron and mesosternum white with black line where connected with propleuron and prosternum. Two rectangular black spots join this line at the lower part of mesopleuron. In front of them, further little black spots at each hind angle of mesopleuron. Mesopleuron pyramidally raised, dull, with very shallow and undefined surface sculpture. Mesosternum dull, moderately deeply and densely wrinkled. Coxae, trochanters, femora, tibiae, tarsi white. Femora and tibiae with black line. Tarsal segments with black apical spots. Inner hind tibial spur/basitarsus = 32/55. Claws bifid, moderately deeply incised, subapical tooth little shorter. Wings yellowish hyaline, radial and cubital cells darker yellow. Costa and stigma light brown, venation, including subcosta, black. First four ventral abdominal segments light whitish brown, the others white. First abdominal tergum smooth and shining, white with basal black and brown stripe, divided in the middle but without triangular patch. Terga 2nd-9th with very fine and very dense surface sculpture. 2nd and 3rd abdominal segments narrower than the others (subg. Tenthredina). Second tergum brown with wider basal and narrower hind black stripe. 3rd and 9th abdominal terga white. 4-7th terga white, each with two lateral suffused, brown, subtriangular patch. 8th tergum dominantly white with narrow basal black line and with basal brown patches. Ovipositor white, rounded with light brown margin. Two apical terga covered with white hairs about as long as the diameter of front ocellus. Hypopygium emarginated as in Fig. 3. Length: 17.0 mm. Length of fore wing: 14.0 mm.
