Notoxus donckieri Pic, 1908

( Figs. 10 , 74 , 80 )

Notoxus donckieri Pic, 1908: 274 .

Type locality. China, Yunnan.

Type material examined. SYNTYPES: 2 ♀♀ [originally mounted on single card, re-mounted], ‘ Yunnan [p] // type [h] // TYPE [p; red label] // Bul. Fr. 1908 p. 274 [h] // Donckieri Pic [h]’ (coll. Pic, MNHN) .

Additional material examined. CHINA: YUNNAN: 1 ♀, ‘ Yunnan Sen [no date / collector]’ (coll. Pic, MNHN) ; 1 ♀, ‘ Chine Yunnan [no date / collector]’ ( NHMW) . VIETNAM: 1 ♀, ‘ Tonkin coll. Madon’ (coll. Pic, MNHN) ; 1 ♀, ‘ Annam-Vinh 1910 // Indo Chine coll. Dussault’ ( NHMB) ; 1 J, ‘ Phuyen Binh II 1907 Fouquet’ (coll. Pic, MNHN) .

Redescription. Female (syntype). Body length 3.3 mm. Head and pronotum reddish, elytra pale reddish, with slightly darker base (ommolates) and brown, vaguely outlined markings ( Fig. 80 ): rather wide transverse band at / behind mid-length, vaguely connected on suture with subapical spot. Legs and antennae reddish.

Body moderately glossy, rather densely punctured. Punctation of pronotum and head mostly rather fine. Punctation in basal half of elytra generally more distinct, coarser than that of head and pronotum, uniform. Body setation mostly appressed to subdecumbent; pronotum with some conspicuously long erect setae, especially laterally, articulated near minute tubercles; elytra additionally with numerous longer suberect setae. Antebasal setose band of pronotum conspicuous, widely interrupted medially.

Head with rather large eyes; tempora nearly straightly narrowing posteriad.Antennae long, distinctly enlarged in terminal third. Pronotum about as wide as head across eyes, globose to slightly elongate in dorsal view. Pronotal horn moderately long, slender, with 4 distinct lateral lobules on each side and wider apical lobule; horn crest distinctly raised, evenly lowering towards horn apex, its lateral margins feebly marked by series of somewhat coarser, distinctly spaced lobules / rugules; dorsal surface covered by distinct rugules. Elytra strongly elongate, 2.1 times as long as wide; humeri distinctly protruding; omoplates and postbasal impression moderately indicated; elytral apices simple.

Male (Phuyen Binh, MNHN). Elytral apices unevenly rounded, with slight gland opening; protibiae slightly sinuous and with distinct angulately produced dilatation on inner side in distal half ( Fig. 74 ); abdominal sternum VII unevenly rounded, with pair of slight posterolateral angles, slightly impressed / flattened postero-medially; tergum VIII forming narrow, arched, widely rounded sclerite; aedeagus as figured ( Fig. 10 ).

Variation. Body length (J ♀) 3.1–3.4 mm. The specimens from Vietnam darker coloured, with rather distinct markings on elytra.

Differential diagnosis. Notoxus donckieri is externally very similar to N. assamensis , N. bellus and N. distortus sp. nov., but differs clearly in the male characters (shape of the protibiae and aedeagus).

Distribution. China: Yunnan ( PIC 1908); Vietnam.

Remarks. PIC (1908) described Notoxus donckieri from an unstated number of specimens collected by M. H. Donckier in Yunnan. All the examined specimens from Yunnan are females, and the only male originates from Vietnam (probably Phu Yen Province in its central part). It is identical with the female specimens from ‘Annam’ (former name for central Vietnam) bearing an identification label ‘ Notoxus assamensis ’ by D. Telnov ( TELNOV 2005). These Vietnamese specimens show no distinct external differences from the types, except for darker colouration which is usually a rather variable character. Despite this fact, their identification should be taken as tentative until confirmed by examination of males from southern China.
