Orange, except as follows: frontal vitta black, triangular and sharply demarcated with a straight anterior margin; face, lower frons and ocellar tubercle and fore tarsus yellow; fore and hind femora with dark but weakly demarcated broad middle bands; mid tarsus, distal tarsomeres of hind tarsus, T4, side of S7 and top of epandrium black. Postocellar bristles strong, closely spaced and far behind level of inner vertical bristles. Male abdominal segment 1 and base of segment 2 petiolate. Sternite 8 twice as large as epandrium, at least laterally dark and shiny, in contrast to dull T6 and epandrium, sparsely setulose.    Material examined    Holotype PERU• ♂; CuscoDepartment, Callanga, Piñipiñi Valley;  1800 ma.s.l.; O. Garleppleg.; MNBG.    Remarks The Peruvian type locality of  M. garleppi, “Callanga, Piñipiñi Valley”, is the type locality for several species.  Gade (1999)discussed the valley and gave an altitude of about 1500 ma.s.l., while discussing the confusion over the place name “Callanga”. According to Peruvian entomologist Julio Rivera (pers. comm.) the ʻcorrectʼ Callanga is in Cusco Provinceat coordinates 12°50ʹ16.80ʺ S, 71°48ʹ28.20ʺ W. Several species are known only from older type material at that locality, so it would be very useful to have new specimens from the area. The collector is listed as Otto Garlepp, but  Papavero (1973)did not mention the highlands of Peruamong the localities at which Otto Garlepp collected. Otto Garlepp’s brother, Gustav Garlepp, is known to have collected at the “High Ucayali River, Peru”. Piñipiñi specimens also appear in the type series of  Mesoconius infestus,   M. obtusiconus Enderlein, 1922,  M. albimanus, and  M. rufithorax, as well as in those of many species of other micropezid genera. Almost all of these are rare species, known only from one or a few low-quality specimens. In most cases, the Piñipiñi localities are cited as “ 1500 mhigh, 1900”, and most are attributed to O. Garlepp, although  Papavero’s (1973)summary of the Garlepp brothers’ travels in South America does not place either of them in Peruin 1900.    Tanypoda garleppi Enderlein, 1922, until recently treated as belonging to  Zelatractodes, is here treated as a secondary junior homonym of  Mesoconius garleppi; it is redescribed below as  M. ottoi nom. nov.in the  M. nonogroup. 5008570317 MNBG O.
