Apteroloma jelineki sp. nov.

( Figs. 3 , 8, 10, 12 )

Type locality. China, Yunnan province, Gaoligong Shan mts, pass 24 km NW Liuku or 7 km E Pianma.

Type material. Hol ot ype: J, ‘ CHINA: Yunnan [province] ( CH 07-26), / Nujiang Lisu Aut.[onomous] Pref.[ecture] / Gaoligong Shan [mts], pass 24 km NW / Liuku or 7 km E Pianma, / 25°58′22″N, 98°41′00″E, 3150 / m, bamboo with shrubs, litter / sifted, 9.VI.2007, leg. A. Pütz [leg.] [p]’ (APEG, will be deposited in ZMHB). Par at ypes: 5 JJ 5 ♀♀, same data as holotype (3 JJ 3 ♀♀ APEG, 1 J 1 ♀ JRPC, 1 J 1 ♀ SMNS).

Diagnostic description. Measurements of the male holotype: TBL 6.1 mm, PMW/PML 1.71, PMW/PBW 1.12, EL/EW 1.28, EW/PMW 1.43.

Body large in size, 5.6–6.3 mm (J) and 6.2–6.5 mm (♀) long. Dorsum in mature specimens light brown, resembling teneral specimens of A. davidis , pronotal disc with large, dark brown medial spot; antennae, mouthparts and legs uniformly light brown ( Fig. 3 ). Dorsal surface very shiny, with fine transverse microsculpture; disc of pronotum almost glabrous, only with very fine and superficial microsculpture. Pronotum and elytra with scattered short erect setae.

Pronotum widest in middle; anterior margin weakly emarginate; lateral margins distinctly bordered, very weakly explanate; sides weakly raised and very weakly sinuate posteriorly ( Fig. 3 ); base very wide, without impressions. Disc with scattered punctures, lateral and posterior areas with strong and dense punctures.

Elytra broadly oval. Each elytron with nine regular striae, stria 3 with ca. 65–68 small punctures; interstriae flat; elytron with narrow epipleural keel; laterally smooth, without serration. Hind wings fully developed.

Male. Aedeagus evenly rounded with short, dorsally elevated apex in lateral view ( Fig. 8 ); sides before apex distinctly broadened and heavily sinuate, apex widely rounded in dorsal view ( Fig. 10 ).

Female. Ventrite VIII widely, regularly rounded posteriorly, spiculum ventrale wide, truncate anteriorly ( Fig. 12 ). Ovipositor with wide and short valvifer with only 2–3 ventromedial setae; triangular, heavily sclerotized coxite bearing numerous setae; stylus modified into strongly curved, apically glabrous, short scraper (as in RŮŽIČKA et al. 2004: 117, Fig. 20 ).

Differential diagnosis. Large species, habitually similar to A. schawalleri Růžička, Schneider & Háva, 2004 . Both species also share the general shape of the aedeagus, which is distinctly broadened before apex and has heavily sinuate sides in dorsal view, and the wide and robust shape of spiculum ventrale in females. Both species clearly differ by the combination of the following characters: dorsum light brown (with only disc of pronotum darker) and with scattered short erect setae in A. jelineki sp. nov. (black and with scattered long erect setation in A. schawalleri ); antennae uniformly light brown in A. jelineki sp. nov. (bicoloured, with antennomeres 1, 2, 10 and 11 ferruginous, and the remaining ones black in A. schawalleri ); pronotum with almost glabrous disc posteriorly very weakly sinuate sides and very wide base in A. jelineki sp. nov. (disc with distinct transverse microsculpture, distinctly sinuate sides and narrow base in A. schawalleri ). Both species can be reliably identified using features of the male genitalia: aedeagus with a dorsally elevated apical part in lateral view and widely rounded apex in dorsal view in A. jelineki sp. nov. ( Figs. 8, 10 ) and with a straight apical part in lateral view and narrow apex in dorsal view in A. schawalleri ( RŮŽIČKA et al. 2004: 117, Figs. 4 , 8 ). Female of A. jelineki sp. nov. differs in the shape of ventrite VIII, which is widely and regularly rounded posteriorly, and truncate anterior margin of spiculum ventrale ( Fig. 12 ). In A. schawalleri ventrite VIII is narrower posteriorly and the anterior margin of spiculum ventrale is widely though weakly emarginate ( RŮŽIČKA et al. 2004: 117, Fig. 11 ).

Etymology. Patronymic, named in honour of Josef Jelínek (Prague, Czech Republic), specialist in Nitidulidae , and a very kind person with a truly encyclopedic knowledge, which he is always ready to share with others.

Bionomics. Type series was individually collected under small stones in a sandy habitat almost without vegetation on the eastern slope of a pass.

Distribution. So far known only from the type locality in China: Yunnan province, situated close to the border with Myanmar ( Fig. 27 ).
