Li, Yajin & Zhang, Hongrui, 2022, Five new species and two new records of Mycterothrips (Thysanoptera: Thripidae) from Southern China, Zootaxa 5214 (4), pp. 544-566 : 544-566

Mycterothrips photiniae sp.n.

( Figs 6–9 )

Female macroptera. Body brown ( Fig. 8 ), all legs brown except tibia apex and tarsus yellowish brown; antennae brown with apex of segment III yellow ( Fig. 6 ); fore wings brown except base pale, clavus brown with apex yellow.

Head wider than long, slightly rounded at cheeks; ocellar setae I absent, setae III situated near anterior margin of posterior ocelli; five or six pairs of postocular setae ( Fig. 7 ). Antennae 8-segmented, segment I with two dorsal apical median setae, II with 3 microtrichial rows on dorsal surface, III–VI with some rows of microtrichia on dorsal and ventral surfaces, VIII slightly longer than VII ( Fig. 6 ).

Pronotum wider than long, weakly sculptured with transverse striations, but smooth medially; one or two pairs of posteromarginal setae; two pairs of posteroangular setae, inner setae shorter than outer one. Mesonotum with CPS anteromedially; median pair of setae near posterior margin. Metanotum reticulate striate, but with irregular longitudinal striations laterally, CPS absent ( Fig. 7 ). Fore wing first vein with seven setae at base and two near apex, second vein with setal row complete; posterior fringe cilia slightly wavy; clavus with 5 marginal setae and one discal seta.

Abdominal tergites II–VIII without ciliate microtrichia on lines of sculpture, but often with a few large irregular microtrichia on sculpture lines at least on segment VIII; tergite II with 3 lateral marginal setae, tergites VI–VIII with S4 setae minute; tergite IX with posterior pair of CPS; tergite X split longitudinally in distal 1/4 ( Fig. 9 ); sternites without discal setae; VII with median pair of setae situated in front of posterior margin.

Measurements (holotype female in microns). Body length 1454. Head, length 100; width across eyes 154. Ocellar setae III length 42. Pronotum, length 125; maximum width 189; posteroangular setae length, inner 58, outer 68. Metanotum median setae length 54. Fore wing length 932. Antennal segments III–VIII length 59, 50, 38, 45, 10, 19.

Male. Unknown.

Specimens examined. Holotype female: CHINA, Yunnan Province, Shilin County, Long Lake, from Photinia serratifolia , 15.iii.2017 (Yajin Li), in collection of Yunnan Agricultural University , Kunming.

Paratypes: 4 females, collected with holotype ; 4 females, from Pinus sp. , collected on the same locality .

Etymology. In reference to the host plant of this species.

Comments. This species runs to grandis in the key to world species of Mycterothrips , but this new species has the body brown, mesonotum with anteromedian CPS and abdominal tergite II with 3 lateral marginal setae.
