KEY TO ANOMALOSIPHUM SPECIES, APTEROUS VIVIPARAE

(Apterae of A. pithecolobii , A. mendeli , A. essigi and A. scleroticum unknown)

1. Dorsum of body weakly pigmented, aphids on slide appearing pale to the naked eye. Dorsal body integument mostly smooth or weakly sculptured..............................................................................................................................................2

– Much of dorsum of body pale brown to dark brown, at least on sides of abdomen.......................................................4

2. Paired processes of tergite VII (minus setae) about 0.9 times as long as processes of tergite VIII; frontal setae about 34 µm long, pedunculate flabellate; dorsum of body almost smooth. In embryo dorsal body setae flabellate, about 15 µm long...................................................................................................... A. philippinense Martin & Agarwala, 1994

– Paired processes of tergite VII 0.50–0.75 times as long as processes of tergite VIII; frontal setae about 23 µm long or shorter, pedunculate or sessile flabellate; dorsum of body smooth or variolose. In embryo dorsal body setae short flabellate or peg-like, 4–6 µm long. ....................................................................................................................................3

3. Urs 1.20–1.37 times ht2; dorsum of abdomen smooth. In embryo dorsal body setae flabellate. .................................... ........................................................................................................................................................ A. takahashii Tao, 1947

– Urs 1.05–1.15 times ht2; dorsum of abdomen variolose or nodulose. In embryo dorsal body setae minute, peg-like or with incrassate, denticulate apices. ................................................................. A. tiomanense Martin & Agarwala, 1994

4. Dorsum of body rather evenly pigmented. Dorsal body setae 19–38 µm long with at least half their lengths cylindrical before widening toward apices. Urs about 2 times ht2. Dorsal integument smooth or variolose. In embryo dorsal setae flabellate with elongate cylindrical basal part, siph. with 2 minute setae in addition to marginal seta of tergite VI................................................................................................................... A. indigoferae Ghosh et al., 1971

– Median zone of abd. often markedly paler than the sides. Dorsal body setae 15–22 µm, flabellate, mostly expanding immediately from bases. Urs 1.38–1.58 times ht2. Dorsal integument strongly variolose or nodulose. In embryo dorsal setae short flabellate, expanding immediately from bases, siph. without setae. ................................................................................................................
