HOLOTYPE: Male: SOLOMON ISLANDS: Malaita:Andalimu-Ngarafata (SW Fiu Riv- er), 8.71666 °S 160.68333 °E, 1 m, 19 Sep 1957, J.L. Gressitt, Acalyphasp. (Euphorbiaceae)( AMNH_PBI 00041490) ( BPBMtype# 16725) ( BPBM).
DIAGNOSIS: Distinguished by the flared anterolateral margins of the pronotum (fig. 4). C. boianotumshares similar coloration with bulbopellaand ruwenzorii, but can be readily distinguished from these by its unilobate proepisternum and lack of visible paragenitalia. It is also similar to carinatus, though with much less pronounced anterolateral projections of the pronotum. Both species have similar coloration and texture, a weakly curved left paramere, and a lack of any groove, fold, or suture along the posterior margin of the pygophore.
DESCRIPTION: COLORATION (figs. 4, 6): Head: Pale yellow-orange; frons without vittae; labium pale, brown apically. Antenna: Pale, apex of AII slightly brown. Thorax and abdomen: Concolorous yellow-orange, paler ventrally; scutellum with two prominent lateral brown spots. Legs: Concolorous yellow-orange, metafemur without dark diagonal stripes. SURFACE AND VESTI- TURE (figs. 4, 6): Head smooth and impunctate; pronotum and scutellum glossy with deep, widely spaced punctation; hemelytra, propleuron, and metepimeron impunctate; setae on dorsum short, white, and simple, most setae knocked off examined specimens. STRUCTURE: (figs. 4, 6) Head: Frons and vertex forming a confluent broad medial tumescence, becoming shallowly depressed adjacent to eyes; vertex without tubercles adjacent to eyes; posterior margin of head medially rounded, not carinate, without transverse depressions adjacent to eyes. Thorax: Pronotum broad, lateral and posterior margins thin and carinate, anterolateral margins strongly flared and lobed, submarginal region of humeral angles weakly excavated, posterior margin weakly upturned, callar region weakly defined; proepisternum unilobed; posterior margin of metepimeron truncate; metanotum not prominent and flared; scutellum swollen. Hemelytra: Costal margin evenly rounded and thinly carinate. Legs: Metatibial spines short and thin. Abdomen: When viewed laterally, abdominal sternite II not angular. MALE GENITALIA (figs. 7D–G, 8B): Right paramere small, broadly triangular (fig. 7E–G); left paramere weakly curved (figs. 7D, 8B); ventral margin of pygophore simple and weakly biconvex, without fold, groove, or mesal suture on left side (fig. 8B). FEMALE PARAGENITALIA: No visible external paragenitalia.
ETYMOLOGY: The epithet boianotumis derived from Latin ( boia, ‘‘collar’’) and Map 2. Distribution map of C. bulbopella, lestoni, and ruwenzorii. Greek ( noton, ‘‘back’’) and reflects the expanded anterolateral projections of the pronotum.
HOST: Known only from the genus Pipturus(Urticaceae).
DISTRIBUTION: Known from the Solomon Islandsand Vanuatu(map 1). PARATYPES: SOLOMON ISLANDS: Guadalcanal:Roroni, 35 kmE. of Honiara, 9.45 °S 160.23333 °E, 10 m, 08 May 1964, R.
