Type material. Holotype (IAECAS) male: CHINA: Jiangxi, Ganzhou City, Shangyou County, Wuzhifeng Town, 25°57.747’N 114°04.158’E, ca. 559 m, 6. X. 2009, leg. Bian & Tong (loc. 13). Paratypes: 3 males, 3 females (IAECAS), the same data as holotype; 2 females (IAECAS): CHINA: Jiangxi, Ji’an City, Suichuan County, Duiqian Town, 26°20.018’N 114°16.662’E, ca. 228 m, 2. X. 2009, leg. Bian & Tong (loc. 10); 1 male, 2 females (IAECAS): downstream of loc. 13, 7. X. 2009, leg. Bian & Tong (loc. 14).
Diagnosis. This species is closely related to A. liselotteae Wewalka, A. schoenmanni Wewalka and A. weinbergeri Wewalka, but can be distinguished from A. liselotteae and A. schoenmanni by the anterior 3/4 of head with microreticulation and the sub-apical spot of elytra large and edge-blurred, from A. weinbergeri by the last sternite without microreticulation, and from other related species by the distal part of parameres extremely enlarged.
Description. Body oblong-oval, moderately convex (Fig. 2). Total length of body 1.95–2.25 mm, width 1.35–1.50 mm.
Head rufo-testaceous to ferrugineous; clypeus regularly rounded, without bead; with a distinct transverse depression behind the clypeal margin; punctures irregular in size and sparsely distributed, a little denser at basal half; anterior 3/4 finely microreticulate; antennae flavo-testaceous, moderately long and slender, not modified (Fig. 10).
Pronotum ferrugineous, somewhat darker along the posterior margin; lateral margins a little paler, distinctly bordered; punctures strong, irregular in size and irregular in distribution, partly coarse, large-sized punctures mainly scattered on posterior third, becoming confluent, coarse and forming striation towards sides; anterolateral corner sharply angled, posterolateral corner a little pronounced towards apex; without microreticulation.
Elytra ferrugineous, with two flavo-testaceous spots, one sub-basal and one sub-apical; punctures fine, sparsely distributed; highly polished and shining; without microreticulation.
Ventral side. Epipleura and the rest of ventral side dark rufo-testaceous to ferrugineous; fine punctures sparsely distributed on metaventrite, metacoxae and on abdomen; without microreticulation.
Legs flavo-testaceous to rufo-testaceous. First protarsal and mesotarsal segments of males slightly enlarged (Fig. 9).
Aedeagus. Penis as in Figs 6–7, parameres as in Fig. 8.
Females. Body length 2.10–2.15 mm, width 1.40–1.45 mm; head and pronotum totally microreticulate; first protarsal and mesotarsal segments not enlarged.
Distribution. China: Jiangxi.
Habitat. For a description of localities 13 and 10 see the habitat of Allopachria wuzhifengensis sp. nov.; the surrounding area of locality 14 is similar to locality 13.
Etymology. The specific name comes from the Latin word “grand” = “thick” and refers to the broad distal part of parameres.
