03B187C93251FFBE69D904FA6CA5F9C4.taxon	discussion	Remarks. This species was previously considered a synonym of A. schlichii (Stebbing, 1914) by Wood (1989). Amasa brevipennis is very similar in appearance to A. striatotruncata (Schedl, 1971) which until recently was also considered a synonym of A. schlichii (Smith et al. 2020 b). The holotype of X. brevipennis (NHMUK) and a paralectotype of X. striatotruncatus (NHMUK) were directly compared by SMS. Amasa brevipennis can be distinguished from A. striatotruncata by the following combination of characters (A. brevipennis given first): declivital interstriae punctate and unarmed vs. interstriae impunctate and granulate on apical half of interstriae 1; all interstriae uniformly convex vs declivital interstriae 1 feebly inflated; circumdeclivital ring smooth and unarmed vs circumdeclivital ring with weakly serrate margin on apical third.	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

03B187C93251FFBE69D9064A6F6FF810.taxon	discussion	Remarks. Amasa fulgens was previously considered a synonym of Amasa resecta (Eggers, 1927) by Hulcr & Cognato (2013: 31). Smith et al. (2020 a) considered this synonymy to be incorrect but did not formally recognize the species. Images of the holotype (NHMW) taken by J. Hulcr, and an image of a nontype specimen determined by Schedl and taken by WS, were examined. Amasa fulgens is clearly distinct from A. resecta and can be distinguished by the following characters (A. fulgens given first): antennal club flat, without sutures (type 5) vs. antennal club flat with three sutures on anterior face (type 4); posterior face of protibiae without granules vs. posterior face of protibiae granulate; declivital interstriae densely setose, bearing 2 – 4 rows of semirecumbent hair-like setae vs. declivity glabrous.	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

03B187C93251FFBE69D902CF6FD2FC20.taxon	discussion	Remarks. The holotype (NHMUK) and two paratypes (NHMUK, NUFM) have been examined. Unfortunately, the antennae are missing from the holotype, but are visible on one paratype (NUFM) and are devoid of sutures. The species clearly has the habitus of Peridryocoetes Wood, 1984, a small genus with six previously described species, distributed from Southeast Asia to Australia. It is characterized by its very stout form, coarsely asperate pronotum with the summit in the basal quarter, and strongly convex, very steep elytral declivity with the apex sometimes undercut.	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

03B187C93250FFBF69D903636F6FFB09.taxon	discussion	Remarks. Images of the holotype (NHMW) were examined. The species was previously considered a synonym of Xyleborus judenkoi Schedl, 1959 (Hulcr & Cognato 2013: 152). An image of an X. judenkoi paratype (NHMW) and a paratype (NHMUK) were examined. However, the species is distinctly different from X. judenkoi with A. immitatrix bearing tubercles along declivital interstriae 1 which are absent in X. judenkoi. The species has the characteristics of Ambrosiophilus given above for A. bispinosulus and is here transferred to that genus. Schedl (1980) proposed an emendation of X. immitatrix to X. imitatrix but this act was unjustified in accordance with article 33.2.3 (ICZN 1999) because Schedl only used the spelling immitatrix in the publication of the original description (Schedl 1975).	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

03B187C93257FFB869D900EB6CD5FE39.taxon	discussion	Remarks. This species was previously considered a synonym of Ambrosiodmus obliquecauda (Motschulsky, 1863) (here placed in Euwallacea, see below) by Wood (1989: 170). Images of the lectotype of Phloeotrogus obliquecauda and a paratype of X. semirufus were examined and compared by SMS and RAB. Both species have somewhat similar elytral declivital sculpturing with two or three pairs of large tubercles on interstriae 2, however they clearly differ in form, especially in the form of the pronotum with is quadrate in dorsal profile in E. obliquecauda and rounded in A. semirufus.

03B187C93255FFBB69D906DF6CC5FE44.taxon	discussion	Remarks. The males of most xyleborines are much smaller than the females, weakly sclerotized, with reduced eyes and non-functional hind wings. However, in a few genera, e. g. Cyclorhipidion, this is not the case. The males of Cyclorhipidion can be recognised by their relatively large size, well-sclerotized body, and characteristic habitus. The head is large, semiprognathous, the mandibles large and powerful, but the eyes and antennae reduced in size relative to the female. The pronotum is elongate, usually as long as or longer than the elytra, widest in the anterior quarter, the sides straight or slightly emarginate, the posterior angles rounded, convex dorsally without an impression anteriorly, nor a median projection of the anterior margin. The elytra are relatively short, rounded posteriorly, the declivity convex without distinct sculpture. The protibiae are curved with a row of strong, socketed teeth on the outer margin extending almost to the base. The description of Xyleborus impar indicates that it clearly possesses the characteristics of Cyclorhipidion males, and the species is here transferred to that genus. The female of C. impar is likely to have been described under a different name. However, males of the great majority of species of Cyclorhipidion are still unknown, and male and female need to be collected in association for a definite association to be made.	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

The species differ only in size (D. robustipennis 5.1 mm long, X. interponens 4.4 mm long), and no other morphological characters of taxonomic significance. We consider them to be synonymous. The case is similar to that of Debus amphicranoides (Hagedorn, 1908), a closely related species to D. robustipennis, and Xyleborus amphicranoides parvior Browne, which again differ only in size (amphicranoides 4.8 – 5.4 mm, parvior 3.3 – 3.8 mm), and have similarly been considered synonymous (Smith et al. 2020 a).	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).

03B187C9325CFFAC69D9066F6C6DFD48.taxon	discussion	Remarks. Hopkins (1915) erected Terminalinus for two Philippine species described from singleton specimens, T. terminaliae and T. dipterocarpi Hopkins, 1915, and defined his genus as having a 5 - segmented funicle; club wider than long, anterior face with two bisinuate sutures, posterior face with one procurved suture; eyes large, coarse, elliptical, acutely emarginate. Schedl (1952 b: 162) examined a severely damaged specimen and a single elytron of purported T. terminaliae specimens but did not state how this species was identified. Based on his observations, he placed the genus in synonymy with Xyleborus Eichhoff, 1864. Later in a paper on American Scolytidae, Wood (1986: 267) examined the T. terminaliae holotype, compared it to species in his collection, concluded the genus was valid, and included an additional nine species (many treated below). In their catalog of the world fauna, Wood & Bright (1992) omitted Wood’s (1986) recognition of Terminalinus and references of these combinations, and the included species were moved to Cyclorhipidion and Xyleborus without comment. Likely due to this catalog omission, and Wood’s (1986) recognition of the Indo-Malayan Terminalinus in a paper on the American fauna, this prior taxonomic action was not rediscovered by subsequent researchers. Unaware of this past action, Hulcr & Cognato (2010) erected a new genus, Fortiborus (2010), for the same species group but did not include T. terminaliae. Our examination of the T. terminaliae holotype (NMNH) shows that it unambiguously fits the concept of Fortiborus and therefore we place Fortiborus in synonymy with the older name, Terminalinus. The generic diagnoses of both genera also overlap. The diagnosis of Terminalinus is that of Fortiborus given by Hulcr & Cognato (2010) and elaborated upon by Smith et al. (2020 a). Species of Terminalinus are distinguished by their large size, 4.4 − 7.1 mm; pronotum robust, elytral declivity flattened and broadened laterally, apex angulate; anterior edge of pronotum extended anteriad, bearing a distinct row of serrations; antennal club distinctly pubescent, type 4; eyes very large, deeply emarginate, apex often acute; scutellum flat, flush with elytra; procoxae contiguous; and mycangial tufts absent.	en	Smith, Sarah M., Beaver, Roger A., Sittichaya, Wisut (2022): One hundred eighteen taxonomic changes among Xyleborine ambrosia beetles (Coleoptera: Curculionidae: Scolytinae).
