Allopachria elongata View in CoL sp. nov.
( Figs. 1 View FIGURES 1 – 2. 1, 2 , 3–5 View FIGURES 3 – 13. 3 – 5 , 15, 17, 19, 21, 22)
Type material. Holotype, male: CHINA: Guangxi, Fangchenggang City, Shangsi County, Shiwandashan National Forest Park, 2010.11.10, leg. Bian & Tong. Paratype: 1 male, the same data as holotype.
Diagnosis. Allopachria elongata sp. nov. can be separated from all species of the genus with similar size by strongly enlarged first pro-tarsal segments and by the male genitalia. Allopachria elongata sp. nov. resembles A. dudgeoni Wewalka, 2000 in habitus, but can be distinguished from A. dudgeoni by its larger size (2.55 mm), larger male genitalia, punctures of elytra more or less denser, strongly enlarged first protarsal segments, and insertion of the second protarsal segment at the middle of the first protarsal segment.
Description. Body regularly oval, attenuated to apex, moderately convex (fig. 1); with longitudinal furrow on lateral margins of elytra. Body length 2.55 mm, width 1.70 mm.
Head testaceous, with black line along eyes; clypeal margin more or less truncate, without bead; punctures fine, irregularly distributed, slightly denser in distal half; anterior half finely microreticulate. Antennae flavo-testaceous, moderately long and slender.
Pronotum dark ferrugineous to black, paler at anterior and lateral margins; lateral margins distinctly bordered; punctures strong, irregular in size, partly coarse; with some wrinkles at basal third; without microreticulation.
Elytra dark ferrugineous to black, with two testaceous spots, one subbasal and one subapical; punctures fine, almost regular in size and distribution; longitudinal rows of punctures distinct; highly polished and shining; without microreticulation.
Ventral side. Margins of metacoxae and abdomen dark ferrugineous to black and rest of ventral side rufo-testaceous; some strong punctures and wrinkles on anterior metaventrite and metacoxal process; small punctures sparsely distribute on metacoxae and on abdomen; without microreticulation.
Legs rufo-testaceous. Male: protarsomere I extremely enlarged, about two times as long as protarsomere II (figs. 15, 17).
Male. Penis (figs. 3–4, 19); parameres (figs. 5, 21).
Female. Unknown.
Distribution. China: Guangxi.
Etymology. The specific epithet refers to the extremely elongated protarsomere I in male specimens. Habitat. River ca. 10 m wide, with some pools, substrate of rocks, gravel and sand (fig. 22).
