Key to species of Ditylometopa Kertész

1 Eyes contiguous medially (males) ................................................................................................................................ 2

- Eyes widely separated medially (females).................................................................................................................... 3

2 Fifth abdominal tergite with a pair of moderately well defined pubescent spots (as in Fig. 5 ); eighth flagellomere bluntly pointed apically ..................................................................................................................... D. elegans Kertész

- Fifth abdominal tergite with pubescence less dense, not forming well defined spots (as in Fig. 6 ); eighth flagellomere sharply pointed apically ...................................................................................................... D. centralensis sp. nov.

3 Lower frons with isolated medial spot of tomentum immediately above antennae, surrounding area bare and shiny, especially along upper margin of lower frons; scutellar spines larger, separated by two times the length of a spine or less; anterolateral areas of fifth tergite with pale hairs, this pale vestiture more diffuse, not forming distinct bands ( Fig. 6 ); occurring in Central America,? Brazil........................................................................ D. centralensis sp. nov.

- Lower frons with more diffuse areas of tomentum above antennae, resulting in less conspicuous shiny areas, upper margin of lower frons mostly thinly tomentose; scutellar spines shorter, separated by greater than two times the length of a spine; anterolateral areas of fifth tergite with inconspicuous dark vestiture, the areas of pale vestiture forming distinct bands that widen posteriorly ( Fig. 5 ); occuring in South America........................ D. elegans Kertész
