Podothrips femoralis Dang & Qiao sp. nov. Figs 1 , 7 , 12 , 13-16 , 20 , 22

Female macroptera.

Bicoloured with head, thorax and abdominal segments VIII–X brown, I–VII yellow but III–VII with brown median area; antennal segment I brown, II yellow with brown basal part, III–VII uniform yellow with VI–VII a little darker apex, VIII brown. All legs yellow with fore and middle coxae and fore femora brown ( Fig. 20 ).

Head 1.2 times as long as wide, cheeks distinctly constricted towards base ( Fig. 1 ); ocellar setae minute; postocular setae pointed at tips, half the length of eye, wide apart from each other ( Fig. 1 ). Mouth-cone short, maxillary stylets reaching base of postocular setae, maxillary bridge present. Antennal segment sense cones: III with 1+1, IV with 1+11, V with 2+2, VI with 11+2, VII with 1 dorsal ( Fig. 7 ).

Pronotum with no sculpture, am reduced, aa, ml, epim, and pa setae well developed with expanded apices, epim setae longest; notopleural sutures complete; basantra well developed, longer than wide ( Fig. 1 ). Metanotum almost smooth; metathoracic sternopleural sutures well developed ( Fig. 22 ). Fore femur expanded; fore tibia with a distinct apical tooth; fore tarsal tooth developed ( Fig. 1 ). Fore wings slightly constricted medially, without duplicated cilia, sub-basal wing setae equal with length, S1 and S2 expanded at apex, S3 acute ( Fig. 12 ).

Pelta hat-shaped with pair of campaniform sensilla ( Fig. 14 ); tergites II–VII with two pairs of wing-retaining setae ( Fig. 15 ); abdominal tergite IX setae S1 and S2 pointed at apex, shorter than tube; tube 0.54 times as long as head; anal setae 1.7 times as long as tube ( Fig. 16 ).

Measurements

(holotype female, in µm). Total length 2440. Head length 260, width across behind eyes210; eye length 85, width 55; postocular setae length 40. Antenna length 440, I–VIII length (width): 35(40), 50(30),55(25),60(30),55(25),50(25),52(25),35(22). Pronotum length 235, width 235; aa 12, ml 12, epim 45, pa 17. Fore wing length 960, sub-basal setae S1-S3 length 20, 15, 15. Pelta length 75, width 130.Tube length 140, anal setae length 240.

Specimens examined.

Holotype female. CHINA, Yunnan, Mengla County, on Bamboo leaves, 22.iv.1997, Y.F. Han. Paratype: one female with same data as holotype; one female, Fujian Prov., Xiamen City, on Bamboo leaves, 29.iv.1991, Y.F. Han; one female, Guangdong Prov., on Bamboo leaves, 29.iv.1992, Y.F. Han.

Comments.

This new species is similar to P. sasacola in forewing without duplicated cilia and body bicoloured, but differs in having all legs yellow with fore legs femora brown, antennal segment V–VI uniformly yellow and VII yellow with apical third brown ( Fig. 20 ), meso- and metanotum brown, all developed pronotal setae expanded at apex ( Fig. 1 ), and fore wing sub-basal setae S1 and S2 expanded ( Fig. 12 ). In contrast, P. sasacola has all legs yellow, antennal segments V–VI yellow with apical half brown, VII uniformly brown, meso- and metanotum yellow ( Fig. 21 ), pronotum aa, ml and pa pointed at apex, epim setae expanded ( Fig. 5 ), and sub-basal setae S1 and S2 pointed ( Fig. 11 ). It is also related to P. odonaspicola and P. bicolor Seshadri & Ananthakrishnan in the bicoloured body, but this new species can be distinguished by forewing without duplicated cilia (forewing with duplicated cilia in P. odonaspicola ), and fore tibia with distinct subapical tooth (fore tibia without distinct subapical tooth in P. odonaspicola ) ( Figs 1 , 4 ), and by fore femora brown (all femora yellow in P. bicolor ).

Etymology.

This species name is composed of one Latin word, femoralis , based on the brown fore femora.
