( Figs 44–50 View FIGURES44–50 )

Type species: Carterica buquetii Thomson, 1860   .

Etymology. Allo, Greek prefix = different. In reference to the different shape of the scape when compared with species of the genus Carterica   . Feminine gender.

Description. Body not flattened; head hypognathous; frons slightly transverse; antennal tubercles elevated, in frontal view, their inner margins together forming a V; antennae distinctly longer than body; scape widened from base to about distal third, from slightly to distinctly sinuous, especially in male, with distinct carina near inferior margin on inner side, preceded by from slightly distinct to very distinct depression, with, moderately abundant long erect setae ventrally; antennomere III notably shorter than scape, not widened, with sparse erect setae ventrally; antennomere IV slightly longer than III; prothorax trapezoidal, forming distinct lateral spine near base (sometimes short, but always distinct), with short constriction between base and spine; prosternal process laminiform; mesoventral process narrow, about as wide as 1/10 of mesocoxal cavity; elytra sub-parallel for basal half, slightly widened from middle to distal quarter, then narrowed, with distinct spine in outer distal angle, slightly sinuous to sutural angle; elytra with humeral carina from base to apex well-marked; elytra with sparse erect setae; epipleuron vertical, not or slightly visible near apex dorsally; dorsal elytral from base to almost apex, more distinct, not curved toward suture distally, innermost carina less distinct basally, about as long as central one (carinae not fused between them distally); femora pedunculate-clavate (club thicker in male); metatarsomere I about as long as II –V together; last abdominal segment similar in both sexes, distinctly narrowed toward apex (sides slightly rounded), with outer angles spiniform.

Remarks. Allocarterica   has the scape similar to that in Batesparna   and Francisparna   . It differs from Batesparna   by the elytra distinctly narrowed distally (wide in Batesparna   ), prosternal process laminiform (distinctly not laminiform in Batesparna   ), and mesoventral process narrow (wider in Batesparna   ). It differs from Francisparna   by the wider body (slender in Francisparna   ), prothorax proportionally larger (small in Francisparna   ), and elytra with 3 dorsal carinae not fused distally (with 2 dorsal carinae fused distally in Francisparna   ). From Sparna   it differs by the elytra not noticeably widened toward distal quarter (clearly widened in Sparna   ), and from Carterica   by the humeral carina reaching elytral apex (present only on basal 2/ 3 in Carterica   ).
