Remarks.

The morphological comparison of holotypes of Ectinogramma isosceloides Thomson , (Fig. 1 A – C View Figure 1 ) and Spinogramma ochreovittata Breuning (Fig. 3 A – C View Figure 3 ) reveals that both species belong to the same genus, Ectinogramma , based on shared morphological characters. Therefore, Spinogramma Breuning is determined to be a junior synonym of Ectinogramma Thomson. Although detailed descriptions of both Spinogramma and Ectinogramma are provided by Breuning and Thomson, respectively, the description of Ectinogramma is enhanced below by examination of both types and additional examined material.

Redescription.

Body slender and elongate (body length / humeral width of elytra: 4.8–8.2) based on 16 specimens of E. isosceloides and one specimen of E. ochreovittata . Eyes finely faceted, lower eye lobe distinctly longer than gena (Figs 1 B, F, G View Figure 1 , 3 B View Figure 3 ). Antennal tubercles distinctly raised and closed to each other (Figs 1 A, E, G View Figure 1 , 2 A – D View Figure 2 , 3 A View Figure 3 ). Antennae slender, distinctly longer than body, scape gradually thickened from middle to apex, apex of scape nearly extending to base of pronotum, scape longer than antennomere III, antennomere III longer than antennomere IV (Figs 1 A, E View Figure 1 , 2 A – D View Figure 2 , 3 A View Figure 3 ). Pronotum sub-cylindrical, slightly expanded posteriorly and distinctly longer than wide (Figs 1 A, E View Figure 1 , 2 A – D View Figure 2 , 3 A View Figure 3 ). Procoxal cavities closed posteriorly and triangular externally. Mesocoxal cavities opened externally to mesepimera. Scutellum linguiform (Figs 1 A, E View Figure 1 , 2 A – D View Figure 2 , 3 A View Figure 3 ). Elytra slender and elongate, gradually constricted from base to middle, and gradually expanded from middle to about apical 1 / 5, finally gradually constricted towards apex, emarginated apically (Figs 1 A, E View Figure 1 , 2 A – D View Figure 2 , 3 A View Figure 3 ). Femora robust, metafemora distinctly shorter than abdominal ventrite I, hind legs distinctly shorter than abdominal ventrite I – III combined (Figs 1 B, C View Figure 1 , 1 F View Figure 1 , 3 B, C View Figure 3 ).

Diagnosis.

Ectinogramma resembles Elongatopothyne Breuning (1963) by (1) slender and elongated body form; (2) slender antennae, distinctly longer than body; (3) elongated pronotum; (4) linguiform and densely clothed scutellum; (5) elytra apically emarginated and coarsely and densely punctate; (6) mesocoxal cavites opened externally to mesepimera; and (7) hind legs distinctly shorter than abdomen. Ectinogramma can be differentiated from Elongatopothyne by the following characters: (1) shorter antennae, less than twice length of body (in Elongatopothyne with antennae three times length of body); (2) scape longer than antennomere III (El. with scape shorter than antennomere III); (3) antennomere III longer than IV (El. with III shorter than IV); and (4) pronotum slightly expanded posteriorly (El. with pronotum not expanded posteriorly).
