Ocularium rufum Pic, 1922: 18.

Sparedrus rufus: ŠVIHLA (1986) : 177.

Type locality. Northern Vietnam.

Type material examined. SYNTYPE (? HOLOTYPE): J, ‘Tonkin [= northern Vietnam], Hoc [? – unreadable word; Pic’s handwriting] // type [yellow label, Pic’s handwriting] // type [red label, printed] // Ocularium n. gen. rufum Pic [yellow label, Pic’s handwriting] // Museum Paris, coll. M. Pic [printed]’ ( MNHN) .

Redescription. Coloration. Body entirely rusty excluding chestnut brown maxillary palpi (except rusty tips of last palpomeres) and apical halves of tibiae ( Fig. 6 View Figs ).

Male. Eyes large and protruding, head across eyes moderately wider than pronotum, nearly parallel-sided behind eyes. Frons between eyes very narrow, eyes almost holoptic. Last maxillary palpomere long securiform ( Fig. 15 View Figs ). Antennae of the examined specimen completely missing. Surface of head densely verrucose, very sparsely and finely yellow pubescent (pubescence maybe secondarily darkened), matt. Pronotum slightly longer than wide, slightly cordiform, anterior margin moderately arcuate, anterior corners rounded, lateral margins sinuate, moderately converging posteriorly, posterior corners obtusely rounded, posterior margin widely rounded. Surface of pronotum sculptured and pubescent like that of head, matt, with a pair of shallow depressions before middle. Elytra very slightly dilated posteriorly, nearly parallel-sided, surface finely punctate, semilustrous, with fine, sparse yellow pubescence, elytral nervation absent. Last tergite barely exceeding last sternite, both shallowly and widely emarginate apically. Tegmen about two thirds as long as aedeagus; aedeagus as in Fig. 29 View Figs .

Female unknown.

Length (J). 8.2 mm.

Distribution. Northern Vietnam.

Comments. Sparedrus rufus belongs to S longicornis species group owing to the shape of the aedeagus (see ŠVIHLA 2006b). The missing antennae could probably be as long as in the preceding species, because their length and form seems to be related to the very narrow frons between eyes in most of species of this group.
