Figure 5D-F, N Xyleborus crinitulus Wood, 1974: 34. Theoborus crinitulus (Wood): Wood 1982 : 774. Xyleborus crinitulus Wood: Wood and Bright 1992 : 721. Theoborus crinitulus (Wood): Wood 2007 : 389. Type material. Holotype (NMNH), paratypes (NMNH, 2), examined. New records. None. Diagnosis. 1.9-2.5 mm, 2.3-2.5 x as long as wide ( Wood 2007 ; Bright 2019 ). This species is distinguished by the broadly rounded and entire elytral apex, posterolateral margins of elytra distinctly carinate to interstriae 8, bearing crenulations of equal size along its length, and very stout elytra, 1.3 x as long as wide. Similar species. Ambrosiodmus Hopkins, 1915 spp. Distribution. Panama ( Panama ), Saint Lucia, Venezuela (Barinas). Biology. This species is only known from Hirtella triandra ( Chrysobalanaceae ) ( Wood 2007 ). Remarks. Wood (2007) reports this species as occurring in Africa however we could not locate further details or published records of this claim. The report from Africa should be considered dubious.
