Key to males of species in the popeye group

1 Antennal postpedicel as long as wide, pointed or rounded apically; IIt1 slightly longer than IIt2, with long hairs basally, tapering in length distally ( Fig. 1 b)........................................................... craigi Evenhuis , sp. nov.

- Antennal postpedicel 2.5–4.0 times longer than wide, pointed apically; IIt1 1.75–2.00 times length of IIt2............... 2

2 Mid tibia contorted, with single thick leaf-like setae at bend ( Fig. 3 )........................ meyeri Evenhuis , sp. nov.

- Mid tibia rounded, swollen or contorted, but without single leaf-like seta at bend of contortion........................ 3

3 Mesoscutum predominantly brown, yellowish laterally; TiII kinked subapically with compact row of 4–5 long black setae ( Fig. 2 ); FII with strong setae restricted to subapical ventral patch............................... elinae Evenhuis , sp. nov.

- Mesonotum predominantly yellow; TiII without such a kink or compact row of strong setae; FII with strong ventral setae in other areas other than or in addition to subapical patch....................................................... 4

4 Swollen area of TiII with “comb” of thick slightly curved and flattened chaetae ( Fig. 4 b); apex of TiII with 2 extremely long, spiky setae, longer than IIt2; mesoscutum without admedian vittae of contrasting color............................................................................................... (Marquesas) … pectinatus Evenhuis , sp. nov.

- Swollen area of TiII without comb of strong chaetae; apical setae of TiII not longer than IIt2; mesoscutum with admedian brown vittae contrasting with yellow ground color.......................................................... 5

5 Mesal surface of TiII with patch of short stubby setae subbasally ( Fig. 6 a, s1); mesoapical row of strong setae interrupted subapically ( Fig. 6 b, s2); postpedicel length 2.5 times width................................. popeye Evenhuis , sp. nov.

- Mesal surface of TiII with row of longer black setae subbasally ( Fig. 5 b, s1); mesoapical row of strong setae continuous from bend to apex, not interrupted ( Fig. 5 b, s2); postpedicel length 4.0 times width................. moorea Evenhuis , sp. nov.
