description: Pseudotrachystola yei sp. nov.
(Figs 3, 6, 9, 12, 15, 18, 21, 24, 28–30)
Material examined. Holotype (female), China: Hubei, Xuan’en County, Qizimeishan, 28 April, 2012, leg. Mao Ye (Entomological Museum of Yangtze University).
Distribution. China: Hubei.
Female. Length 21 mm, humeral width 9 mm. Body black, densely clothed with brown pubescence, mixed with sparse white pubescence which is more distinct and uniform on underside and legs. Antenna clothed with grayish yellow pubescence from third antennomere to eleven antennomere; scape to sixth antennomere fringed with dense hairs below, seventh sparsely fringed. Elytra scattered with short, erect white and black setae which are more obvious on apical third; each elytron before apical third decorated with an irregular lateral spot of black pubescence, behind which several small black spots arranged along suture and outer edge; elytral base scattered with small grayish-white spots which are denser along outer edge.
Head coarsely rugose-punctate, frons wider than long, vertex shallowly concave between upper eye lobes. Eyes coarsely faceted; lower lobe wider than long, distinctly shorter than gena. Antennae about 1.5 times as long as body; antennal tubercles strongly elevated, widely separated from each other; scape stout, about as long as fourth antennomere, third longest, fourth to tenth gradually shortened, eleventh about as long as fifth. Pronotum wider than long, width-length ratio about 4: 3; each side with a strong and acute spine at middle; disc slightly rough, with three low tubercles, postmedial tubercle deeply grooved posteriorly. Scutellum trapeziform. Elytra narrowed posteriorly and apex separately rounded; surface thinly and shallowly punctate; base of each elytron with a feeble median longitudinal swelling, basal half with sparse granules of different size. Apex of terminal ventrite straight. Legs moderately long, each mesotibia with an oblique groove near external apex, claws widely divergent.
Female genitalia. Spermatheca and sternites 7–8 are shown in figures 28–30. Blind end of spermathecal capsule nearly reaching C-form structure.
Remarks. The new species is different from the type species by the elytra having small, black lateral spots, no rounded and without white edge and the elytral base without distinct fine granules among the coarse granules, scutellum trapeziform, the antennae with distal 5 antennomeres surpassing elytral apex, and the shape of spermatheca is also different.
This species is described from a single female specimen. The holotype is deposited in the Entomological Museum of Yangtze University.
Etymology. The species is named after the collector, Mr. Mao Ye (Hubei, Xiangyang), who continuously present cerambycid specimens to the second author. The Chinese name is designated as 叶氏伪糙天牛.
