Diplosmittia

- Two undescribed species were collected, in addition to D. forficata , described from La Selva, Costa Rica, by Andersen (1996). The genus has recently been reviewed by Pinho et al. (2009) and Wiedenbrug & Silva (2016) added an additional species from the Dominican Republic. The single specimen of D. sp. ZUR-1lacks antennae and bears a well developed inferior volsella; it may belong elsewhere but is placed in Diplosmittia until more complete material can be collected. Diplosmittia sp. ZUR-2 resembles D. beluina Andersen (described from La Selva, Costa Rica) but has 13 antennal flagellomeres, with an AR of 3.0-3.4, and a more sharply pointed anal point; D. beluina has 10 flagellomeres and an AR of 0.62. Both taxa have a long costal extension. The two taxa may be conspecific but more material is necessary to determine antennal vaiability.
