Key to the genera and species of Sericothripinae   from Saudi Arabia

1. Metasternal plate anterior margin with deep U- or V-shape invagination medially ( Figs 2 View FIGURES 1–7 , 9 View FIGURES 8–14 )............. Hydatothrips   ... 2

- Metasternal plate anterior margin either transverse ( Fig. 19 View FIGURES 16–24 ) or with shallow emargination medially ( Fig. 26 View FIGURES 25–31 )................................................................................................. Neohydatothrips   ... 3

2. Ocellar triangle closely striated ( Fig. 1 View FIGURES 1–7 ); metanotum longitudinally striate ( Fig. 3 View FIGURES 1–7 ); setal pair S3 on abdominal tergites IV–VI at posterior margin, with only three setae anterior to S3 ( Fig. 4 View FIGURES 1–7 ); tergite IX with three pairs of mid-dorsal setae ( Fig. 5 View FIGURES 1–7 ); abdominal segments IV–V yellow ( Fig. 32 View FIGURES 32–35 )............................................................. H. adolfifriderici  

- Ocellar triangle with widely spaced striae ( Fig. 8 View FIGURES 8–14 ); metanotum longitudinally reticulate ( Fig. 10 View FIGURES 8–14 ); setae S3 on abdominal tergites IV–VI placed far ahead of posterior margin, with 6–8 setae anterior to S3 ( Fig. 11 View FIGURES 8–14 ); tergite IX with two pairs of mid-dorsal setae ( Fig. 13 View FIGURES 8–14 ); abdominal segments reddish brown ( Fig. 34 View FIGURES 32–35 )......................................... H. bahaensis   sp. n.

3. Occipital apodeme confluent with posterior margin of compound eyes ( Fig. 16 View FIGURES 16–24 ), ocellar setae pair III arising at external margin of triangle and shorter than distance between their bases; metasternal plate with anterior margin transverse ( Fig. 19 View FIGURES 16–24 ); sternites without discal microtrichia or posteromarginal comb ( Fig. 20 View FIGURES 16–24 ); tergite IX with only one pair of mid-dorsal setae ( Fig. 21 View FIGURES 16–24 ); abdominal segments I–VI unicolor pale yellow to white, without trace of shadings ( Figs 36, 37 View FIGURES 36–40 )................
