description: <i>Spinifornax elongatus</i> Otto, new species Fig. 6 <b>Diagnosis.</b> Very elongate body form, along with tricoloration will distinguish the new species from all other <i>Spinifornax</i> species in Southeast Asia. <b>Description. Female holotype:</b> Length, 13.0 mm. Width, 3.0 mm. Body elongate, tapering towards the elytral apex; tri-colored with head, antennae, apical pronotal margin, scutellum, apical third of elytra, venter, and legs black; remaining areas of pronotum red; basal two-thirds of elytra orange; head, pronotum and elytra clothed with dense, short, recumbent setae (Fig. 6). <b>Head:</b> Very closely and shallowly punctate, subspherical; frons convex, without median keel or groove; surface shiny; apical margin of epistomal part of epicranium evenly rounded, about 2.5 times wider than base; mandibles stout, bidentate. <b>Antennae:</b> Filiform, reaching about half the length of the body; antennomere III slightly longer than IV; antennomeres IV–X each longer than wide, subequal; antennomere XI slightly longer than X. <b>Pronotum:</b> Very closely, shallowly punctate; surface shiny; as long as wide, with short hind angles; lateral sides gradually narrowing anteriorly; disc convex, simple; base sinuate. <b>Scutellum:</b> Shining; closely, shallowly punctate; sub-triangular and distally rounded. <b>Elytra:</b> Striate; interstices elevated; surfaces closely, shallowly punctate. <b>Legs:</b> First tarsomere as long as the combined lengths of the remaining four on mesothoracic and metathoracic tarsi; tibiae rounded in cross section; metathoracic tarsomeres I–III simple; metathoracic tarsomeres IV excavate-emarginate; metathoracic tarsomere V short with basally toothed claws. <b>Venter:</b> Shallowly punctate, with recumbent white setae; hypomeron with well developed, basally opened lateral antennal grooves; metathoracic episternum parallel-sided; metathoracic coxal plates medially 3.0–6.0 times wider than laterally. <b>Type material.</b> <b>Holotype</b>, female, with label data: " MALAYSIA, SABAH, Kinabalu National Park, headquarters, 6º 00'N 116º 32'E, 1550-1650m, 12–15.VII.2012 " / " BMNH {E}, 2013–134, M. Geiser " / " <b>HOLOTYPE:</b>, <i>Spinifornax</i>, <i>elongatus</i>, Otto, det. R.L. Otto, 2014" (♀ handwritten behind species name on label) [red printed label]. Holotype in BMNH. <b>Distribution.</b> The species is known from a single locality in the Malaysian Peninsula. <b>Biology.</b> The type locality is a middle montane environment. Developmental stages remain unknown. <b>Etymology.</b> The specific epithet of the new species is derived from the elongate form of the body. <b>Remarks.</b> Many species within the group are either bicolored or unicolored. Tricoloration of orange, red, and black as present in this species, and, along with its elongate body form, is quite unique for the genus and will distinguish it from all known species of <i>Spinifornax</i> distributed in the Asian, Oceanic, and Neotropical regions.
