Corethrella quadrivittata Shannon & Del Ponte, 1928 View in CoL

Material examined. 1 female, Bom Retiro (SC), S27°53’39” W49°27’43”, 942m a.s.l., 18.XI.2017, CDC trap, LC Pinho et al. (col.) GoogleMaps .

Distribution. Mexico, Costa Rica to Suriname, south to Argentina and Brazil (BA, MT, SC*).

Five known Corethrella species are newly recorded for Brazil, nine have new distributional records within the country and four new species are described, raising to 46 the number of recognized species in Brazil. Some comments on these records should be addressed. The species Corethrella longituba , found at 1538m a.s.l. in Campos do Jordão, São Paulo state, was previously known only from individuals collected at maximum elevation of 150m in the Caribbean. Moreover, the single specimen collected, a male, shows a small variation in the distribution of sensilla coeloconica compared to the original description (one sensillum on each of flagellomeres 1, 2, 9–13, differing from the description, which presents one sensillum on 1, 10–13) and so it might represent an undescribed species. In the description of C. dicosimoae, Borkent (2008) defines the coronal suture of females as short, whilst in two specimens studied here it is long. These specimens were also found at high elevations of 1600m a.s.l. significantly higher than previously known records of between 5 and 106m; these too might represent an undescribed species. For both cases, it is necessary to collect and examine more specimens to test if they do represent new species or if those are only intraspecific variations. Until then, the most parsimonious decision is to consider the second option.
