Podalonia yunnana LI & YANG 1992: 85 ,,. Holotype:, China: Yunnan: Xiaguan (Beijing Agricultural University ).

D e s c r i p t i o n translated from Chinese by Q. Li: Male: " Body length 15 mm. Vertex, upper frons and upper gena with black long setae mixed with less white long setae, other portion of head, thorax with white long setae mixed with less black long setae; lower frons and clypeus with appressed silver setae. Median and upper frons with longitudinal and oblique rugae; clypeus flattness (fig. 140). OOD: POD: OOD: IODP: IODC: length of antennal scape (fig. 148): pedicel: flagellomere I: II: III: X = 1: 3: 4.5: 12.8: 8: 4: 1.1: 4.5: 4: 4: 3. Pronotal collar length: width = 4.7: 9.8. Surface of mesothorax, metathorax, propodeum rougher than that in female; metanotum with less transverse rugae and punctures. Forewing (fig. 145). Fore tarsomeres I nearly symmetry. Relative length of hindtibia: tarsomere I: II: abdominal petiole = 24.5: 3: 7: 18.5; Genitalia ( Figs 141, 142 and 143 ), penis valve with a large thorn apicoventrally evidently larger than that in P. flavida (KOHL) . Other characters as in female.

F e m a l e: Body length 15-16 mm. Black; abdominal terga I-II whole, III basally, sterna I apically, and II - III whole reddish yellow; wing pale yellowish brown, veins pale brown. Head, prothorax, mesothorax, and propodeal side with black long setae mixed with less white long setae; propodeal enclosure and posterior surface of propodeum with white long setae; without appressed silver setae.

Vertex and clypeus with dense punctures; frons with punctures denser than that on vertex and clypeus, with oblique rugae medially. Clypeus (fig. 144) slightly bulging medially, anterior margin prominent. OOD: POD: OOD: IODP: IODC: length of antennal scape (fig. 149): pedicel: flagellomere I: II: III: IX = 1: 2.8: 4.8: 13.3: 13.4: 3.8: 1.5: 6.5: 4.2: 4: 2.5.

Pronotal collar length: width = 5.5: 11.8, with punctures same as that on vertex, without longitudinal furrow. Scutum with punctures evidently denser and larger than that on vertex, connected each other, many of them polygon-shape; median portion of scutum with several coarse, longitudinal rugae. Scutellum with dense, longitudinal rugae, with sparse punctures between rugae. Metanotum without rugae, with very sparse punctures. Propodeal enclosure with short rugae mixed with punctures, surface rough, with incomplete median carina. Episternal sulcus present. Mesopleuron, metapleuron and propodeal side with punctures mixing with irregular rugae, surface rough. Mesosternum with transverse rugae mixed with dense punctures. Forewing (fig. 147). Fore tarsomeres I (fig. 146) dissymetry, tarsomeres IV symmetry. Relative length of hindtibia: tarsomere I: II: III: abdominal petiole = 26: 14: 8: 5.7: 14."

Podalonia yunnana is similar to P. flavida , but the latter differs in having more smooth surface of head and thorax, sparse puncta, shorter petiole and different shape of male genitalia (LI & YANG 1992: 85).
