Lestodiplosis oomeni Harris, 1982: 20 View in CoL .
Material. Holotype male, 5 paratypes males, 9 females and 10 larvae (deposited in BMNH ((E)251546–59), USNM (a19250–2) and RMNH) were collected and reared from on Calacarus carinatus (Green) (Acarina: Eriophyidae ) feeding on Camellia sinensis (L.) in Indonesia (Harris 1982). We examined the USNM paratypes: Nos 19250 (male, collected 16-xii-1977), 19251 (female, 11-xi-1977) and 19252 (larva, 16-xii-1977). Those specimens were mounted in Hoyer’s medium. Although we could observe what we needed to see on these specimens, this impermanent medium is gradually crystallizing, and the specimens will eventually become unrecognizable.
Description. Adult. Wing length (arculus to apex) 0.8 mm in male, 1.0 mm in female; R 5 nearly straight, reaching wing apex; M 4 absent; Cu 1 evident [ Fig. 22b View FIGURES 22 ]. Head [ Fig. 22a View FIGURES 22 ] with 11-14 frontoclypeal setae, axillary palpus 3-segmented, occipital protuberance short, eye bridge 4-5 facets long, facets sparse opposite antennal bases. Antennae with 12 flagellomeres.
Male. Flagellomere with three separate whorls of looped circumfila [ Figs 22d, e View FIGURES 22 ]. Terminalia [ Fig. 22c View FIGURES 22 ]: gonocoxite narrow, mesobasal lobes low, rounded, setulose; gonostylus short, narrowest near midlength; aedeagus flared near midlength, prominently narrowed below globular tip; cerci ovoid; hypoproct bulging and conspicuously setulose on ventral half, broadly convex apically, with two apical setae.
Female. Flagellomeres: circumfila consisting of two horizontal whorls of short-looped bands, longitudinally linked with two simple vertical bands [ Figs 22f, g View FIGURES 22 ]. Terminalia: cerci broadly ovoid, setose along length with field of about 15 closely approximated short and thick distal setae [ Fig. 22h View FIGURES 22 ].
Pupa unknown.
Larva. Length 1–1.5 mm long. Head [ Fig. 22i View FIGURES 22 ]: head capsule triangular, longer than wide, posterolateral apodemes nearly as long as capsule; antennae thin, tapered, curved forwards, longer than capsule width. Sternal spatula absent. Meso- and metathorax each with two pseudopods, abdominal segments 1–7 with three pseudopods, pseudopods with sparse setulae, greatly narrowed before tip [ Figs 22j, k, m, o View FIGURES 22 ]. Papillae as in Figs 22 View FIGURES 22 i–o, dorsal papillae with all six setae of same length. Terminal segment with 8 terminal papillae with long setae, a number of additional socketed setae and many setulae [ Figs 22n, o View FIGURES 22 ].
Remarks. To differentiate males from its two known congeners from Indonesia, see under L. lacciferi above. Larvae of L. oomeni and L. syringopais were both described. In L. oomeni the head is acutely triangular with antennae that are longer than head width, all dorsal papillae bear setae of similar length, and the terminal segment has setae additional to those of the eight terminal papillae. In L. syringopais the head is acutely triangular with antennae shorter than head width, the outer pair of dorsal papillae have setae that are much longer than the two inner pairs, and the terminal segment has six papillae with or without setae [possibly broken off] and no additional vestiture [ Fig. 23q View FIGURES 23 ].
Biology. Type specimens were collected and reared from a population preying on the purple tea mite Calacarus carinatus (Green) (Acarina: Eriophyidae ) that was feeding on the tea plant Camellia sinensis (L.) in Java (Harris 1982). Additionally, the larvae were observed preying on the pink tea mite Acaphylla theae (Watt) (Acarina: Eriophyidae ) and the scarlet or false tea mite Brevipalpus phoenicis (Geijskes) (Acarina, Tenuipalpidae ) (Harris 1982).
Geographical distribution. This species is currently known from Java: Gambung, near Bandung, 16 & 22.xii.1977; Pasir Nangka, Cianjur Regency, south-west of Bandung, 11.xi.1977; Tambakan, Tangkuban Perahu, north of Bandung, 18.vi.1977 (Harris 1982).
