Differential diagnosis

Species with basoflagellomere elongate and subacute apically, face yellow, metasternum bare and abdominal terga 2–5 distinctly marginated (Figs 2D, 3 G–H). It differs from S. grandicornis by having a dorsal yellow macula on the katepisternum and the male metatrochanter with a ventral spine-like process or calcar.

Geographical distribution

Widespread species in the Oriental and Australasian Regions (Japan west to India and south to Australia, Papua New Guinea, New Caledonia, Micronesia, Samoa and other Pacific islands, including French Polynesia).

Status in French Polynesia

Present; recorded from Marquesas Islands, Gambier Islands, Tuamotu Islands, Austral Islands and Society Islands.

Flowers visited

Ischiodon scutellaris has been seen visiting two plant species, Hippobroma longiflora (L.) G.Don and Apetahia raiateensis Baill. (Campanulaceae). Apetahlia raiateensis is a shrub endemic to the three trachytic plateaus of Raiatea and it is listed as Critically Endangered by the IUCN(UICN France, MNHN & DIREN Polynésie française 2015). In terms of conservation, the identification of the pollinators of this species may be useful (F. Jacq, pers. comm.). A couple of males at the MNHN were collected on flowers of Messerschmidia argentea (L. f.) I.M.Johnst. (= Tournefortia argentea L. f. = Heliotropium foertherianum Diane & Hilger, 2003). Due to the overall similarity between females of I. scutellaris and A. nigripilosa in the field, some records of visited flowers cannot be confidently assigned to one of these species and they are not included.

Biology

Cochereau (1966, 1974) observed the food web of I. scutellaris (as Xanthogramma sp.) in Mangareva, Gambier Islands. Larvae of I. scutellaris attacked several aphids (Hemiptera: Aphididae) on different plants: Rhopalosiphum maidis (Fitch, 1856) and Sitobion avenae (Fabricius, 1775) on several species of Poaceae; Brevicoryne brassicae (Linnaeus, 1758) on Brassica oleracea L., (Brassicaceae); and Aphis gossypii Glover, 1877 on several plants belonging to Araceae, Asteraceae, Malvaceae and Myrtaceae. He also observed that the pupae of I. scutellaris were parasitized by a braconid wasp (Hymenoptera: Braconidae).

Genetics

The GenBank accession numbers for this species are: 28S gene (MF446488, specimen ZFMK- DIP-00019720), 18S gene (MF446444, specimen ZFMK-DIP-00019720), protein-coding COI gene (MF446540, specimen ZFMK-DIP-00019720; MF446516, specimen ZFMK-DIP-00019721). The BOLD Process IDs for the DNA barcodes (5′–COI) for this species are: SYC 1600-14 (= KX053515, specimen symbiocode_01632),SYC2519-14(= KX053518,specimen symbiocode_02597), SYC3765-14 (= KX053516,specimensymbiocode_03845),SYC4375-14(= KX053520,specimensymbiocode_04455), SYC4907-14 (= KX053519, specimen symbiocode_04987), SYC5089-14 (= KX053521, specimen symbiocode_05172), SYC5521-14 (= KX053513, specimen symbiocode_05606), SYC7453-14 (= KX053514,specimen symbiocode_07570),SYC7894-14(= KX053517,specimen symbiocode_08018) and SYC7895-14 (= KX053522, specimen symbiocode_08019). The Barcode Index Number (BIN) for these specimens is BOLD:AAE5566 (https://doi.org/10.5883/BOLD:AAE5566).

Remarks

Old records of this species are not easy to verify, as some authors used S. grandicornis and I. scutellaris as synonyms for a long time.
