Francisparna   , gen. nov.

Type species: Sparna macilenta Pascoe, 1888   .

Etymology. Combination of the first name of Francis Polkinghorne Pascoe (1813-1893) with Sparna   . Feminine gender.

Description. Body flattened; head opisthognathous; frons elongate; antennal tubercles elevated, their inner margins together form a distinct V; antennae longer than body; scape sinuous, distinctly widened toward apex, with long, abundant setae along inner side; antennomere III shorter than half of scape length, lacking abundant, long setae, not widened; prothorax trapezoidal, with short, distinct spine near base; elytra elongate, from parallel-sided to slightly divergent at about basal half, then slightly widened to about distal sixth, where it is gradually narrowed; elytra with distinct humeral carina from base to apex; epipleuron vertical, not visible dorsally; elytral surface lacking long erect setae, with two longitudinal carinae from base to apex, outermost curved inside at distal area, innermost fused to outermost near apex; elytral apex with distinct spine on lateral angle, rounded toward unarmed sutural angle; femora pedunculate-clavate; metatarsomere I slightly shorter than II–V together.

Remarks. Because we could not examine specimens of the type species this description of the genus is based on photographs and literature. Even so, it is very evident that Francisparna   noticeably differs from Sparna   by the scape distinctly sinuous and widened, antennomere III pubescent without long and abundant setae ventrally, and the elytra is not clearly widened toward apex. In Sparna   , the scape is cylindrical and narrower, antennomere III is longer and has long, abundant setae ventrally, and the elytra is clearly widened. It differs from Batesparna   by the body slender, outermost dorsal carina of the elytra not curved near apex, and innermost carina varying from not to indistinctly fused with outermost carina near apex.

Photograph of the holotype is available at Bezark (2017).

Species included: Francisparna macilenta (Pascoe, 1888)   , comb. nov. (see photograph of the holotype at Bezark 2017).
