Type material

Holotype, male, with original label “Mandian I/3B, 16.03.2009”, China, Yunnan, Jinghong, Nanban River Watershed National Natural Reserve, Mandian (Forest), 22.12961°N, 100.66612°E, alt. 746 m, 16.III.2009, leg. Lingzeng Meng, IOZ(E) 1905892; paratype, 1 male (dissected), with original label “Naban II/3B1, 16.03.2009”, China, Yunnan, Jinghong, Nanban River Watershed National Natural Reserve, Nanbanchachang (Forest), 22.15810°N, 100.66543°E, alt. 729 m, 16.III.2009, leg.

Description

Body measurements: BL 3.0–3.2 mm, BW 1.1–1.2 mm, PL 0.5–0.6 mm, PW 1.0–1.1 mm. Head black, pronotum and anterior portions of elytra yellowish-brown, remaining portions of elytra, underside and antennae dark brown to black, legs light-brown. All parts covered by brown setation.
Head very coarsely punctate. Compound eyes very large, white in color, with microsetation; median ocellus well developed, yellow-brown in colour (Fig. 3). Antennae (Fig. 5) relatively long, extending well beyond base of prothorax, with 10 antennomeres, with dense brown setation; scape slightly longer than wide, pedicel shorter and slightly transverse; funicle with 4 very short and transverse antennomeres (antennomeres III to VI); antennal club with 4 antennomeres (antennomeres VII to X), each one longer than funicle, first three club segments gradually expanded and widest at apex; terminal antennomere (antennomere X) longest, antennomere VII second longest; antennomere VIII shorter than antennomere VII but longer than antennomere IX; length/width ratio of antennomere X 3.33, much slender than antennomere VII, VIII and IX, which is about 1.67, 1.22 and 1.12 respectively; antennomere X widest at about middle and narrowly rounded apically; ratio of antennomere lengths: 6.5:4.5:1:1.5:1:1:15:11:9.5:20; length/width ratios: 1.08:0.82:0.33:0.37:0.25:0.25:1.67:1.22:1.12:3.33. Pronotum (Figs 1, 4) 0.53 times as long as wide, widest posteriorly; sides straight, converging from base to apex; lateral carinae complete, without raised bead; apical edge truncate, anterior angles oblique, posterior angles slightly acute; posterior edge bisinuate, so that median rounded lobe is formed between two emarginations; disc moderately coarsely punctate with a pair of broad basal impressions. Prosternum (Fig. 4) in front of coxae short, prosternal process complete, very strongly narrowed at base, apex finely acute; procoxal cavities widely open externally, closed internally.
Elytra (Fig. 1) 1.96 times as long as wide and 4.58 times as long as pronotum, widest at apical third; sides slightly diverging and then apically converging and independently rounded; disc relatively flat, steeply sloping laterally, slightly so posteriorly, with a broad, lateral depression in apical third; punctation finer than on pronotum but moderately dense. Epipleura (Fig. 2) gradually narrowed posteriorly and extending almost to apex. Mesoventrite (Fig. 2) slightly transverse, without procoxal rests, not separated by sutures from mesepisterna; mesoventral process moderately long. Abdomen (Fig. 6) about 1.3 times as long as wide, with six ventrites, the first two of which are connate; ventrite 1 laterally about 1.3 times as long as ventrite 2, but at midline much shorter behind large metacoxal cavities; intercoxal process represented by a slightly broadly rounded projection; ventrites 2–4 subequal in length, 5 slightly longer and rounded. Legs light-brown with stout, light-brown setation. Tarsi simple.
Aedeagus (Figs 7–9) with basally angulate phallobase; long, narrow, apically attenuated parameres, which curve mesally at apex, and somewhat shorter, apically attenuated penis with short basal struts attached to base of parameres. Penis curve ventrally (Fig. 8).
Female. Unknown.

Differential diagnosis

The new species Trichodryas slipinskii sp. n. differs from both described congeners in only 10-segmented antennae and its larger size.

Distribution

China: Yunnan Province.

Etymology

Patronymic, species is dedicated to Prof. Adam Ślipiński (CSIRO, Australia).

Remarks

Háva (2008)[1] provided an incorrect illustration of the antenna of Trichodryas esoterica as it does not correspond to the illustration and description in Lawrence and Ślipiński (2005)[2]. According to the measurements of Trichodryas esoterica by Lawrence and Ślipiński (2005)[2] and the picture of Trichodryas lawrencei by Háva (2008)[1], the ratio of antennomere lengths is a good way to separate these species.
Lawrence and Ślipiński (2005)[2] pointed out that there are definitely only 10 antennomeres in the specimen of undescribed Trichodryas sp. from Kalimantan Barat and probably in the unknown Trichodryas sp. from the Sabah as well. The antennae of the two specimens from Yunnan described above definitely are 10-segmented.
