Goniochenia (Baranosa) honorata ( Baly, 1869) comb. nov.

Mesomphalia honorata Baly, 1869: 85 (original description).

Type locality. ‘Bolivia’.

Type material examined. HOLOTYPE: ♂, pinned, ‘ Bolivia [w, hw by Baly, cb] || Type [w, p, s, c, rf] || Bolivia [hw] | Baly Coll. | 1905—54. [w, p, cb] || Mesomphalia | honorata | Baly | Bolivia [g, hw by Baly, cb] || Type [hw by Baly on underside of preceding label]’ ( BMNH).

Remarks. The species was unknown to subsequent authors and was listed only in catalogues. SPAETH (1914) transferred Mesomphalia honorata to Pseudomesomphalia (= Stolas ) and BOROWIEC (1999a) to Cyrtonota Chevrolat, 1836 . I had the opportunity to examine its type and found that in fact this species belongs to Goniochenia Weise, 1896 as it has three basal shiny and nearly glabrous antennomeres while species of Mesomphaliini have four or more.

The species belongs to the subgenus Baranosa Weise, 1899 as it does not have large spots formed by dense pubescence on elytra and it is most similar to G. discors ( Spaeth, 1928) and G. peruviana Hincks, 1956 from Peru, all sharing quite high postscutellar gibbosity. Goniochenia honorata has lateral profile of elytra distinctly concave behind the postscutellar gibbosity and the latter is also distinctly higher than in G. discors , which has the profile behind gibbosity nearly straight. Goniochenia discors has dorsum mostly black with several yellow specks scattered over elytral disc with only a few reaching to explanate margin while G. honorata has a large oval spot in the middle of explanate margin of each elytron connected by narrow band across elytra and the pattern is reminiscent to that of Stolas zona ( Spaeth, 1902) . However, other species of Baranosa display large variability in dorsal patterns and it is likely both species will be found to possess additional colour forms. So far, each species is known only from the holotype. According to the original description ( HINCKS 1956), Goniochenia peruviana has similarly convex elytra and quite similar pattern and possibly is conspecific with G. honorata . However, I have not examined its type and thus do not propose the synonymy. The remaining species of Baranosa have much less convex elytra, see key published by SPAETH (1928).

BOROWIEC (1999a) synonymized Cyrtonota tutelata ( Spaeth, 1932) with G. honorata based on notes in unpublished manuscript of F. Spaeth but this synonymy is incorrect, see remarks under Cyrtonota delicosa ( Baly, 1872) for additional information.

Distribution. Bolivia ( BALY 1869).
