Brachyacantha octostigma Mulsant, 1850: 539. Crotch 1874: 212. Gorham 1894: 188. Leng 1911: 311.

Material examined.

Guatemala • 2♀; Totonicapan, V. Sta. María; 1850 m; 19 Jun 1973; Ginter Ekis leg. (USNMNH) Panamá • 1♀; V. Chiquiri; 2000-3000 ft; Champion leg. (USNMNH) .

Diagnosis.

Oval body. Elytra black, each elytron with five yellow spots. Male abdomen with several ventrites emarginated and depressed. Male genitalia with penis guide wide, shorter than the parameres, not truncate at apex, symmetrical, sides parallel but convergent at apical ⅓ (Fig. 30 View Figures 29–32 ); parameres curved, wide at base, narrowed to apex, apex acute, setae arising from the apex and the convex side margin (Fig. 29 View Figures 29–32 ); penis curved in basal ½, apex without alae, basal capsule crested, inner arm of basal capsule long and slender (Figs 31 View Figures 29–32 , 32 View Figures 29–32 ).

Distribution.

México and Central America.

Discussion.

The coloration of this species is very similar to that of the ursina group, but the male genitalia are different, with a shorter penis guide with the apex not truncate. The material was identified by comparison with previously identified as B. octostigma by J. Chapin in 1956 (USNMNH), the diagnosis of the male and the male genitalia is based on Mexican specimens of the same series.
