Taeniothrips musae (Zhang & Tong) comb.n.

( Figs 6–12 )

Javathrips musae Zhang & Tong, 1990: 193 .

This species was described from China, Yunnan Province, on 19 females and 12 males. The head is slightly prolonged in front of the eyes ( Fig. 7 ), but in other characters the species is typical of Taeniothrips . The metanotal median setae are variable in position ( Fig. 10 ), being far from the anterior margin in the holotype, but sometimes at the anterior margin. This appears to be a fourth member of the picipes -group ( Mound et al. 2012) but, in contrast to the other three species, the tibiae of musae are yellow, not brown, and the fore wing clavus is pale, not shaded in the basal half. As the only description of this species is in Chinese, a redescription is provided here.

Female macroptera. Body brown to dark brown; yellow at all tibiae and tarsi ( Fig. 7 ), also antennal segments III–V, segment V brown in distal 1/4 ( Fig. 6 ); fore wings brown with base paler ( Fig. 12 ). Head slightly prolonged in front of eyes; constricted behind eyes; with two pairs of ocellar setae, pair III long and situated inside ocellar triangle; five pairs of postocular setae present, pair one smaller than others. Antennae 8-segmented, III and IV with apex neck-like, with forked sense cone; segments III–V and basal half of VI with rows of microtrichia; segment VI with inner simple sense cone; segment VIII longer than VII. Maxillary palps 3-segmented. Pronotum with lines of sculpture, weakly medially, with 18–22 discal setae; 2 pairs of long posteroangular setae; posterior margin with 2–3 pairs of setae. Basantra membranous, without setae. Ferna divided ( Fig. 9 ). Mesonotum with transverse sculpture, anterior campaniform sensilla present, median setae near posterior margin. Metanotum weakly reticulated, smooth medially; median metanotal setae far behind anterior margin but sometimes at anterior margin; campaniform sensilla present ( Fig. 10 ). Mesothoracic furca with spinula, metathoracic furca absent. Fore wing first vein with 7 (sometimes 8) setae basally, 1 medially and 2 distally; second vein with complete row of 10–12 setae; clavus with 5 marginal setae and 1 discal seta. Abdominal tergites II–VII with no sculpture mesad of setal pair S2; tergite I with short S1 setae; tergites II–V with median setae small, longer on tergites VI–VIII; tergite VIII with long regular posteromarginal comb; tergite IX with two pairs of campaniform sensilla, median setae reaching posterior margin; tergite X not split. Sternites without discal setae; setae S1 and S2 on sternite VII arising in front of margin ( Fig. 11 ). Ovipositor well developed.

Male macroptera. Similar to female; sternites III–VII each with large pore plate ( Fig. 8 ).
