Duffelsa parvula sp. n. , holotype, male. A. pygofer, ventral view; B. pygofer, posterolateral view; C. pygofer, lateral view; D. aedeagus, ventral view; E. aedeagus, lateral view. Etymology. The species name is a Latin masculine adjective meaning “small”, signifying the small body size. Description of male. Head ( Fig. 2A–D ). Mostly ochraceous. Eyes greyish yellow, with dense golden hair along posterior margin. Black markings along frontoclypeal suture and median black spot enclosing ocelli. Lorum with paired black markings. Anteclypeus with small black patches laterally. Postclypeus prominent, transverse cross-section angular. Rostrum with apex blackish, extending to hind coxae. Thorax ( Fig. 2A, C ). Pronotum longer than head, almost ochraceous; inner area having no makings; pronotal collar symmetrically with and irregular black markings along inner margin of anterior part, and with paired black spots on posterolateral area. Mesonotum fundamentally greyish green with the following black markings: median arrow-shaped fascia reaching anterior margin of cruciform elevation; inwardly curved fascia along each parapsidal suture; interrupted fascia along the laterally of each parapsidal suture; paired small spots on scutal depressions and paired markings on anterior angles of cruciform elevation. Legs ( Fig. 2E ). Greyish green with brown patches. Fore femora swollen and equipped with three dark ochraceous spines beneath: primary spine pointed and oblique to femur; secondary spine broader with acute tip, erect; subapical spine short. Wings ( Fig. 2A–B ). Hyaline. Forewing with longitudinal fuscous markings on apical cells, with distinct fuscous spots on transverse veins of apical cells 2, 3 and 5; and with marginal series of minute fuscous spots present on apices of longitudinal veins of apical cells. Hindwing has no markings. Abdomen ( Figs 2A–D , 8A–B ). Cylindrical balloon, noticeably longer than head and thorax together, brown with black markings on posterior margins of tergites. Timbal cover scale-like, ochraceous; timbal mostly concealed by timbal cover. Opercula convex, upside-down triangular, widely separated and longer than wide, extending beyond posterior margin of abdominal sternite II. Abdominal sternites mostly light brown, with slightly-raised tubercle-like projections on centrolateral surface of sternite III. Abdominal sternite VIII oblong, with posterior margin truncated. Genitalia ( Fig. 3A–E ). Pygofer elliptical in ventral view, light brown with apex ochraceous. Dorsal beak pointed, almost the same height of anal styles. Distal shoulders broadly triangular, distally extended into pointed lobe. Basal lobes relatively short and small in lateral view, oblique paramedian, substantially confluent with pygofer margin in ventral view. Uncus with median lobe bifurcated sub-basally, with the two sub-lobes tapering apically extruding laterally in ventral view. Aedeagus S-shaped, with floccules at apex. Distribution: China ( Yunnan ). Remarks. This new species is similar to D. orientalis comb. n. in colour and shape, but can be distinguished from D. orientalis comb. n. by the pronotum with distinct paired black spots on posterolateral area, the forewing with fuscous spots on transverse veins of apical cells 2, 3 and 5, and the median lobe of uncus bifurcated with two sub-lobes extruding laterally in ventral view.
