N o t e s o n t y p e s: Jedlička founded his species on four specimens and noted that the "Type" (= holotype) would be stored in his collection (which is now in the Prague museum) and "Cotypen" (= paratypes) in the Klapperich collection (today stored in several collections, among them also in the Paris museum, as proved by a photograph). But the distribution of the type material was obviously later changed, as in the Prague museum the holotype and a female paratype are extant. The holotype was originally pinned, later glued to card with genitalia extracted, the right middle leg is missing, the hind leg is separated from the body and glued separately to card, so also is part of the right antennae, the median lobe, partly broken, is in an embedding agent in ventral position together with both parameres. The paratype is pinned and in good condition, only the right antennomeres 6 to 11 are missing.

D i a g n o s i s: A Haplochlaenius species of large size with hindwings reduced, head middle-sized with green-brassy reflection, pronotum middle-sized, cordate, with redcoppery reflection (sometimes also with an additional greenish tinge), elytra oblong, black, with carinate intervals, legs black, antennae with antennomeres 1 to 3 black, the remaining ones brownish. Habitus see Fig. 1.

R e d e s c r i p t i o n: Body length 22.7-25.8 mm; width 8.7 - 9.5 mm.

Colour, microsculpture: Elytra, abdomen, and legs black, head with green-brassy reflection, pronotum with red-coppery reflection (often also with an additional greenish tinge), palpi dark, antennae with antennomeres 1 to 3 black, the remaining ones brownish. Microsculpture pattern on head consisting of very weakly engraved isodiametric meshes, somewhat stronger on pronotum, hence surface shiny, on elytra isodiametric meshes in males strongly engraved, surface only moderately shiny, in females meshes more strongly engraved, causing a completely matt surface.

Head ( Fig. 1 ) middle-sized, somewhat narrower than pronotum (ratio PW/HW: 1.25- 1.35, holotype), frons and vertex moderately convex, finely and sparsely punctured, between eyes unpunctured, with frontal furrows shallow, elongate, clypeus finely punctured, bisetose. Eyes medium-sized, almost hemisphaerically protruding, temples short, rectlinear, of about one sixth of eye diameter (seen from above). Mandibles short and broad, palpi elongate, slender, apical palpomeres not dilated. Mentum ( Fig. 5 ) bisetose, with mentum tooth bilobed, lobes distinctly protruding, hardly one third as long as lateral lobes, submentum bisetose. Ligula wide, bisetose. Antennae long and slender, in males reaching scarcely to middle of elytra, and with about antennomere 5 reaching pronotal base, antennomeres 1 and 2 with some fine setae apically except obligatory setae, antennomere 3 with fine setae of different length, sparsely arranged, about 3.4 times as long as 2 in males, antennomere 4 to 11 pubescent.

Pronotum ( Fig. 1 ) medium-sized, cordate, only somewhat wider than long (ratio PW/PL: 1.10-1.14 (holotype), widest somewhat before basal half. Basal margin only a little wider than anterior margin (ratio PAW/PBaW: 0.85 [holotype] - 0.91), and somewhat narrower than pronotum at middle (ratio PW/PBaW: 1.25-1.27 [holotype]). Anterior margin weakly emarginate, anterior angles rounded, somewhat projecting forward, from there slightly curved laterally to basal two thirds, from there basad distinctly sinuately narrowed to posterior angles which are somewhat obtuse-angled and widely rounded at tip. Only 1 lateral seta in posterior angles, distinctly positioned forward at about length of antennomere 2. Disc weakly convex, lateral channel relatively wide (about as wide as antennomere 2), in some specimens somewhat narrower. Basal fovea large but shallow, continuing apicad in a narrow furrow and reaching the end of basal third. Midline distinct, deeply engraved, especially in apical half, hardly reaching anterior and basal margin. Base and basal fovae with dense and coarse seta bearing punctures, base at middle with some vertical wrinkles. Disc with sparse and fine punctures, bearing finest short setae, toward lateral and anterior margin with somewhat more dense and more coarse seta bearing punctures, setae on disc mostly rubbed off.

Elytra long-ovate with humeri completely rounded, moderately convex, base about as wide as pronotal base (ratio EL/EW: 1.44-1.56 (holotype), widest distinctly behind middle. Scutellar pore puncture small, at beginning of stria 1, scutellar stria long. Striae finely punctured. Intervals 1 to 7 keel-like elevated, the odd intervals more strongly formed and more raised than the even ones, interval 8 in the basal half flat or weakly convex, with a weak or suggested carina in the apical half. Without subapical excision, each elytron weakly obtuse-angled at apex, rounded at tip or slightly dentate, elytra slightly gaping. The faces of the carina and the other not carinate intervals with dense, somewhat granulate punctures bearing yellowish-brownish setae, the edge of the keels glabrous and shiny. Hindwings reduced, about half as long as elytra.

Sterna: Pro- and mesosternum, mesepisterna and abdomen with fine and scattered punctures bearing fine, short setae, metepisterna and metasternum with somewhat denser and stronger punctures. Prosternal process elongate, somewhat acutely narrowed, unmargined, somewhat deepened at middle (ventral view). Metepisterna very short, somewhat wider at anterior margin than long at ventral margin.

Legs: Average for Haplochlaenius species, protarsi of males with protarsomeres 1-3 strongly widened and with ventral spongy pubescent vestiture.

Median lobe of aedeagus: Large (with basal part partly open), voluminous, gently arcuate, with well developed apical capitulum at about right angle to apical part in lateral view ( Fig. 3a ), apical lamella in dorsal view Fig. 3b.

C o m p a r i s o n s: Chl. klapperichi JEDL. can be compared with the macropterous species Chl. costiger CHAUDOIR 1856 , Chl. insularis ( UÉNO 1964) , and Chl. sabahensis KIRSCHENHOFER 1998 , also having the head and pronotum with metallic reflection, the legs completely black, and the elytra carinate, but is readily separated by the stouter body with long-ovate elytra with humeral angle almost completely reduced (caused by brachyptery), the male genitalia are also different. In habitus it is closest to Chl. evae nov.sp. and Chl. nanlingensis DEUVE & TIAN 2005 which are also brachypterous and hence have about the same form of the elytra (humeri only somewhat more suggested) with intervals carinate but these species are completely black (with exception of the light antennomeres 4-11), additionally the construction of the median lobes is different (see Figs 3a, b, 4a, b , and Fig. 15 in DEUVE & TIAN 2005).

D i s t r i b u t i o n: Described from the Chinese Province of Fujian, the species was recorded as new for Jiangxi ( KIRSCHENHOFER 2012), based on some specimens I have sent him and coming from the series mentioned below (Unfortunately the shown habitus photograph of a specimen said as coming from the locality "Wufugang" has a different origin. It deals with a paratype now in the Paris museum).

In the collection of the Institute of Zoology, Chinese Academy of Sciences, Beijing, there is a male specimen, documented by a phoptograph, with following data: Jiangxi, Anfu, Wugongshan, N27.44591, E114.18827, 1220m, 2006.6.27, Liu Ye, Liang Hongbin, Teiji Sota leg., confirming, together with the material cited below, the assumption that this species (as in the case of Chl. nanlingensis , see below) has a wider distribution than originally thought.

M a t e r i a l e x a m i n e d (excepttypes):

15, 33: China, NE Jiangxi, Wufugang, 1100-1300 m, eastern slopes, 27°59N / 118°02E, 14.V.- 20.VI.2011 (NMW, cTURN, WR). 1, 1 with same data but: 1140-1500 m, 29.IV.-27.V.2010 (cWR).

H a b i t a t: No notes on the biotope or circumstances of collecting were made in the description. The specimens from Wufugang were collected in a secondary mixed forest with Pinus sp. and Castanopsis sp., mostly in dry places with rich shrub undergrowth, with the help of pitfall traps provided with a mixture of beer and ethylene glycol.
