( Figs. 51-54 , 82-85 ) Material examined. Holotype ♂ and 1 ♀ paratype from Thailand , Trang , January-February , 1899, W.L. Abbott ( USNM ). Actual label location is “Trong lr Siam”. Additional Paratypes : Thailand , Trang , W.L. Abbott , 2 ♂ , 1 ♀ ( USNM ) . Adult habitus. General color appears to be pale yellow brown with pale wings, but the color pattern is obscured by specimen condition. Male. Forewing length 20 mm . Hemiterga slender at tip and slightly expanded at base in dorsal aspect; tips with a small cluster of sensilla basiconica ( Figs. 51-52 ). Tergum 9 with median sensilla basiconica patch anterior to hind margin. Aedeagus membranous, armed with small triangular spines and microtrichia in broad central band ( Fig. 53 ); dorsum bearing a pair of small tubercles set posteriorly to a small dorsolateral bare spot. Female. Forewing length 24 mm . Subgenital plate sub-parabolic with narrow median notch ( Fig. 54 ). Sternum 8 with sparse patch of bristles in center of plate but rest of sterna 8 and 9 bearing only fine scattered setae. Egg. Outline oval, length ca. 0.30 mm, width ca. 0.26 mm ( Fig. 82 ). Collar short, ca. 0.11 mm wide and bearing a series of evenly spaced vertical struts which extend to rim ( Fig. 83 ). Chorionic surface covered throughout with coarse pits centered in follicle cell impressions; inner walls of FCIs irregularly punctate ( Fig. 84 ). Micropylar row subequatorial ( Figs. 82 , 84 ). Larva. Unknown. Etymology. The species name, used as a noun in apposition, is based on the type locality. Figs. 55-58. Kamimuria turbinata adult structures. 55. Male terminalia, 56.

The hemiterga of this species generally resemble those of K. jariyae and K. atra (described above), and K. zonata (described below), and the aedeagal armature is of the same general type for the four, however shape and lobing of the aedeagus differs, and only K. trang has the cylindrical, membranous apical lobe ( Fig. 53 ). The five damaged specimens comprising the type series were previously determined by S.G. Jewett, Jr. as K. kelantonica Klapálek , a species known from “Kelanton, Ost Malakka ” ( Klapálek 1912 ); we assume this site to be on the island of Borneo.
