Batesparna   , gen. nov.

( Figs 10–13 View FIGURES 10–17. 10–13 )

Type species: Sparna platyptera Bates, 1881   .

Etymology. Combination of the surname of Henry Walter Bates with Sparna   . Feminine gender.

Description. Body slightly flattened; head hypognathous; frons elongate; antennal tubercles somewhat elevated, in frontal view, their inner margins together distinctly V-shaped; antennae distinctly longer than body; scape widened from base to about middle, slightly sinuous, especially in male, with distinct carina near inferior margin of inner side, preceded by shallow sulcus, with short, abundant erect setae ventrally; antennomere III with sparse, short, erect setae ventrally, noticeably shorter than scape, not widened; antennomere IV slightly shorter than III, especially in female; prothorax trapezoidal, forming short, but distinct spine near base (sometimes absent), with short constriction between base and spine; prosternal process distinctly narrowed centrally; mesoventral process about as wide as 1/4 of mesocoxal cavity; elytra very gradually widened from base to apex, slightly narrower near outer distal angle, with distinct spine in outer distal angle, rounded toward unarmed sutural angle; elytra with humeral carina well-marked from base to apex; elytra with sparse erect setae; epipleuron vertical, slightly visible dorsally near apex; dorsal elytral surface with two longitudinal carinae (outermost more distinct) from near base to near apex, not curved toward suture distally(innermost less distinct) especially distally, usually not fused with outermost near apex, but sometimes slightly fused; femora pedunculate-clavate; metatarsomere I about as long as II–V together; last abdominal segment similar in both sexes, distinctly narrower toward apex, especially in distal half, with outer angles spiniform ( Fig. 11 View FIGURES 10–17. 10–13 ).

Remarks. Batesparna   differs from Francisparna   gen. nov. and Allocarterica   gen. nov., by the elytra distinctly widened distally (slightly widened in Francisparna   and Allocarterica   ). Batesparna   can be separated from Sparna   by the elytra only slightly widened toward distal area (visibly and distinctly widened in Sparna   ), and from Carterica   by the humeral carina reaching elytral apex (present only on basal 2/ 3 in Carterica   ).

Species included: Batesparna platyptera ( Bates, 1881)   , comb. nov. ( Figs 10–13 View FIGURES 10–17. 10–13 ).
