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 daweishanensis sp. n.

( Figs 18–24 )

Female macroptera. Body brown ( Fig. 18 ); antennae wholly brown; all legs brown except tibia apex and tarsus yellowish brown ( Fig. 20 ); fore wings brown except base pale; clavus brown with apex pale ( Fig. 24 ).

Head wider than long, slightly rounded at cheeks; ocellar setae I present, setae III situated near anterior margin of posterior ocelli; 5–6 pairs of postocular setae ( Fig. 19 ). Antennae 8-segmented, segment I with two dorsal apical median setae, II with 3 microtrichial rows on dorsal surface; III and IV widest at middle and tapering in distal necklike third; III–VI with some rows of microtrichia on dorsal and ventral surfaces; VIII slightly longer than VII ( Fig. 20 ).

Pronotum wider than long, weakly sculptured with transverse striations, inner posteroangular setae shorter than outer pair; two pairs of posteromarginal setae. Mesonotum with CPS absent; median pair of setae near posterior margin, Metanotum reticulate striate, but with irregular longitudinal striations laterally, CPS absent ( Fig. 19 ). 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 ( Fig. 24 ).

Abdominal tergites and laterotergites without ciliate microtrichia on lines of sculpture; tergite II with 4 lateral marginal setae; tergites VI–VIII with S4 setae minute; tergite IX with only posterior pair of CPS; tergite X split longitudinally in distal 1/3 ( Fig. 22 ); abdominal sternite IV–V with 0–1 discal setae, VI with 1–2 discal setae; sternite VII with median pair of setae situated in front of posterior margin ( Fig. 21 ).

Measurements (holotype female in microns). Body length 1557. Head, length 101; width across eyes 168. Ocellar setae III length 70. Pronotum, length 140; maximum width 194; posteroangular setae length, inner 85, outer 89. Metanotum median setae length 62. Fore wing length 895. Antennal segments III–VIII length 54, 57, 36, 44, 10, 20.

Male Unknown.

Specimens examined. Holotype female: CHINA, Yunnan Province, Pingbian County, Dawei Mountain, from Gardneria multiflora , 3.viii.2017 (Bo Kong), in collection of Yunnan Agricultural University , Kunming.

Paratypes: 6 females, collected with holotype .

Etymology. The new species is named after collected place.

Comments. This species runs to M. auratus in the key to world species of Mycterothrips by Masumoto and Okajima (2006), and these two share the following character states: Ocellar setae III near anterior margin of hind ocelli; mesonotum without campaniform sensilla anteromedially; abdominal tergum II with four lateral marginal setae; sternites III–VII with discal setae. However, this new species differs in having antennae wholly brown, pronotum with two long discal setae near anterior margin, abdominal tergites without ciliate microtrichia along lines of sculpture, tergite IX with only posterior pair of CPS, sternites IV–VI with 0–2 discal setae. This species is also similar to M. nastarani , but that has the body uniformly yellowish white, mesonotum with CPS, and sternites III–VII with more than 3 discal setae.
