Gressitt, Acalypha sp. (Euphorbiaceae) ( AMNH _PBI 00041490) ( BPBM type# 16725) ( BPBM ). DIAGNOSIS: Distinguished by the flared anterolateral margins of the pronotum (fig. 4). C. boianotum shares similar coloration with bulbopella and 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 boianotum is 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 Islands and Vanuatu (map 1).
