Cephaloleia atripes (Pic, 1926) comb. nov.

( Fig. 2 )

Amplipalpa atripes Pic, 1926b: 8 (original description).

Type locality. Original type locality ‘Brésilʼ specified by DESCARPENTRIES & VILLIERS (1959) to Brazil, Goiás, Rio Verde based on the label data of the holotype.

Type material examined. HOLOTYPE: glued, ‘GOYAZ | RIO VERDE [w, p, cb] || coll Pic [w, hw by Pic, s] || n sp prés | caerulea [w, hw by Pic, s] || type [y, hw by Pic, s] || TYPE [r, p, cb] || atripes | n sp [w, hw by Pic, s]’ ( MNHN).

Remarks. PIC (1926b) described this species presumably based on a single specimen as the description is written in singular and only a single length measurement was given. Therefore I consider the specimen holotype by monotypy. Pic placed the species in the genus Amplipalpa Harold, 1875 (= Oediopalpa Baly, 1859 ) and compared it to A. foveipennis Pic, 1923 . Amplipalpa atripes since its description has been listed only in catalogues (e.g. UHMANN 1957a, 1964).

I have studied the holotype and the species does not belong to the tribe Spilophorini as it has setigerous pores present only in anterior corners of pronotum. I find that it belongs to Cephaloleia as it fits with the concept of that genus ( SEKERKA 2014). Among Cephaloleia it is very distinct and easy to separate because it has metallic blue elytra, serrate latero-apical margins of elytra, head abruptly constricted behind eyes and vertex separated from head by a deep sulcus thus the eyes appear to project laterally. There are only five uniformly metallic blue species of Cephaloleia ( C. caeruleata Baly, 1875 , C. dilatata Uhmann, 1948 , C. emarginata Baly, 1875 , C. metallescens Baly, 1885 and C. tarsata Baly, 1859 ) all differing in head continuously constricted behind eyes without sulcus separating vertex. Cephaloleia atripes has also quite unusual shape of pronotum as it has anterior corners obliquely truncate ( Fig. 2 ) while all uniformly metallic blue species of Cephaloleia have anterior corners rounded. Distribution. Brazil: Goiás ( DESCARPENTRIES & VILLIERS 1959).
