Apophylia pacholatkoi , new species

( Figs. 14 and 17 )

Material examined. – Holotype - male, Laos, Phongsaly province, Phongsaly environs, 1500 m, 21 41.2'N 102 6.8'E, coll. P. Pacholátko, 28 May. - 20 Jun.2003 ( NHMB).

Paratypes – 18 males, same data as holotype (13 paratypes in NHMB, 5 in JBCB) ; 2 males, Laos, Phongsaly prov., Phongsaly env., 1500 m, 21 41'N 102 6.8'E, coll. P. Pacholátko, 6-17 May.2004 ( NHMB) .

Description. – Male. Body slender, flattened, parallel, dull, pubescent. Head bicolorous; vertex, postgenae, frontal tubercles and underside black; anterior part of head and mouthparts yellow; mandibles brownish. Antennomeres 1 to 5 yellow, antennomere 6 darkenned or black, antennomeres 7 to 11 black; antennomeres 1 infuscate dorsally (occasionally all yellow antennomeres darkenned dorsally). Pronotum, scutellum and underside black. Legs yellow, last two tarsomeres infuscate. Elytra metallic green.

Labrum transverse, covered with three long setae at each side, anterior margin slightly sinuate. Anterior part of head with microsculpture, sparsely covered with very fine punctures and long pale setae. Frontal tubercles large, subtriangular, slightly elevated above vertex, lustrous. Interantennal space with distinct furrow. Vertex dull, covered with large dense punctures and dense fine short pale hairs. Antennae slender, last 3 antennomeres strongly dilated ( Fig. 17 ), antennomeres 3 to 11 distinctly flattened. Antennae 0.65-0.75 times as long as body; length ratio of antennomeres 1 to 11: 18-7-13-19- 16-14-13-12-9-13-21.

Pronotum transverse, 1.72-1.80 times as broad as long, widest before the middle. Anterior margin widely shallow sinuated, lateral margins rounded, posterior margin almost straight, with small shallow incision in the middle. Anterior and posterior margins thinly bordered, lateral margins indistinctly bordered. Anterior angles widely rounded, posterior angles obtusely angulate, near each corner with setigerous pore. The stout ridge deeply interrupted in the middle is situated along anterior margin. Surface uneven, with two very large depressions laterally. Anterior margin and the stout ridge sparsely covered with very large punctures, lustrous, nearly glabrous. The rest of surface with smaller dense punctures and dense short pale hairs, dull.

Scutellum subtriangular, with apex widely rounded, densely covered with small punctures and short pale hairs, dull. Elytra densely covered with small punctures and short dense pale hairs. Humeral calli well developed. Epipleura distinct, gradually narrowed to apex. Macropterous. Underside with microsculpture and fine punctures, covered with dense short pale hairs. Last visible sternite with large semicircular excision. Basimetatarsomere twice as long as two following metatarsomeres combined. Apices of basipro- and basimesotarsomere prolonged and directed downwards, crescent-shaped. Claws bifid. The shape of aedeagus as in Fig. 14 . Body length 4.95-6.00 mm (holotype 5.75 mm).

Female. Unknown, see also remarks under A. kubani , new species, and A. borowieci Bezdek ˇ.

Etymology. – Dedicated to my dear friend Petr Pacholátko (Brno, Czech Republic), a well known specialist in Scarabaeidae (Sericinae) and the collector of the type series.

Remarks. – A. pacholatkoi , new species, in having extended apical antennomeres and characteristic shape of aedeagus, is the typical member of A. pallipes -group. The structure of aedeagus of A. pacholatkoi is closely related to A. clavicornis Samoderzhenkov, 1988 , with the apical process distinctly curved ventrally ( Figs. 13-14 ). The above mentioned species can be distinguished by the shape of extended apical antennomeres which are distinctly broader in A. pacholatkoi , new species ( Figs. 16-17 ).
