Cui, Yanze & Wang, Jun, 2019, The genus Anaphothrips (Thysanoptera, Thripidae) in China, with three new species, Zootaxa 4700 (2), pp. 246-258 : 249-253

Anaphothrips nonporous sp. n.

( Figs 4 , 15, 21 , 27, 32, 33 , 38, 44 )

Female mac. Body brown, head and thorax sometimes slightly paler; legs yellowish brown; antennal segments I and III yellow, segment IV yellow with brown apex, segments II, V–VIII brown but II and V paler ( Fig. 27 ). Fore wing pale brown ( Fig. 32 ). Head 0.8 times as long as wide, dorsal surface sculptured with irregular transverse reticulations behind eyes; eyes ventrally with 6 pigmented facets; ocellar setae III arising outside ocellar triangle ( Fig. 4 ); antennae clearly 8-segmented, segment III with pedicel, segments III–IV with small forked sense cone, III–VI with rows of microtrichia at both dorsal and ventral surfaces ( Fig. 27 ). Pronotum with weak transverse sculpture lines, posterior margin with one pair of slightly longer setae ( Fig. 15 ). Mesonotum sculptured with transverse reticulations, median setal pair arising on posterior third. Metanotum with polygonal sculpture, campaniform sensilla absent, paired median setae arising on anterior third of sclerite ( Fig. 21 ). Fore wing first vein with about 11 setae irregularly spaced, second vein with 8 setae ( Fig. 32 ). Abdominal tergites II–VII with transverse sculpture lines weak medially, campaniform sensilla arising close to posterior margin, posterior margins usually with very small lobes at each side ( Fig. 38 ); tergite VIII spiracles occupying less than one third of lateral margins, posteromarginal comb complete, microtrichia with wide bases but shorter medially ( Fig. 44 ). Sternites II–VII with transverse sculpture lines laterally.

Measurements (holotype female in microns). Body length 1284. Antennae length 245; antennal segments I–VIII length (width): 19(28), 33(27), 37(16), 34(18), 36(18), 47(18), 10(8), 17(5). Head length 116, basal width 153; eyes length 60; ocellar setae I–III: 21, 19, 19; postocular setae I–III: 16, 23, 18. Pronotum median length 126, width 180. Fore wing length 726.

Female mic. Similar to macropterous female, but fore wing only about 0.9 times as long as pterothorax width ( Fig. 33 ).

Measurements (micropterous female in microns). Body length 1416. Antennae length 256; antennal segments III–VIII length: 44, 37, 39, 50, 10, 19. Head length 110, basal width 142.

Male. unknown.

Specimens examined. Holotype female mac., China, Inner Mongolia, Yakeshi City, Wuerqihan Town (49°35.77'N, 121°25.09'E), 10.vi.2018, from grasses (Yanze Cui).

Paratypes: 2 female mac., 12 female mic. same data as holotype; China, Heilongjiang Province: Daqing City, Longfeng Wetland (46°30.74'N, 125°12.68'E), 12.vi.2018 , 1 female mac. from grasses (Jun Wang); Mohe City, Tuqiang Town (52°56.85'N, 122°46.73'E), 11.viii.2018 , 7 female mic. from grasses (Jun Wang).

Distribution. China (Inner Mongolia, Heilongjiang).

Remarks. The new species is similar to A. swezeyi and A. floralis in having 8-segmented antennae and the metascutum without campaniform sensilla. However, it has sculpture lines on the median third of the tergites ( Fig. 38 ); the teeth of the posteromarginal comb on tergite VIII are short with wide bases and also shorter medially ( Fig. 44 ); the body is mainly brown with head and pronotum sometimes slightly paler. In contrast, A. swezeyi lacks sculpture lines between S2 setae on tergites; abdominal tergite VIII has a long and fine posteromarginal comb; the body is yellow. This new species is distinguished from A. floralis in the key above.
