Hemiterga simple, slender, finger shaped and armed on inner margins and on apex with a few sensilla basiconica ( Fig. 29 ). Abdominal tergum 9 with a median patch of sensilla basiconica; tergum 8 with a few sensilla basiconica in mesal field. Aedeagus simple, tubular, entirely membranous and armed on the apical half of sac with a fairly continuous field of minute to small triangular spines ( Fig. 31 ). Figs. 28-32. Kamimuria jariyae adult structures. 28. Head and pronotum, 29. Male terminalia, 30. Female terminalia, 31. Aedeagus, lateral, 32. Femur. Female. Forewing length 23 mm . Subgenital plate wide, triangular and long, extending over most of sternum 9; apex of plate with a small notch ( Fig. 30 ). Vagina membranous, spermatheca a large, inflated, sac-like structure. Egg. Outline oval with wide, short collar. Chorionic surface covered throughout with coarse pits, each pit centered in a follicle cell impression; ca. 11 pit rows visible in lateral aspect and ca. 6 pits in each row between collar and micropylar line. Pits below micropylar line similar to those above line; area around collar with an irregular surface, including ridges on sides of collar, but pits absent in collar zone ( Figs. 76-77 ). Larva. General color brown patterned with pale areas on head and thorax. Head pattern mostly brown but with narrow, pale M-line, pale tentoria and pale midlateral spots on occiput. Occipital row complete; pronotum completely fringed laterally with short, stout bristles. Abdominal terga with short, stout intercalary bristles, dark clothing bristles and well developed posterior bristle row. Occiput, posterior margin of pronotum and median longitudinal area of abdomen fringed with long silky setae. Cercal swimming fringe well developed, anal gills absent. Etymology. The matronym honors Professor Dr. Jariya Chanpaisaeng of Kasetsart University, Bangkok for her assistance in this project. Diagnosis. Among Thai and Vietnamese Kamimuria this species is most easily distinguished by the coarsely and rather uniformly punctate egg. Males have moderately long, slender hemitergal lobes, similar to those of K. atra and K. atrocephala but they are more attenuated near the tips in this species ( Fig. 29 ) and the aedeagus is also distinct (compare Figs. 7 , 12 and 31 ).
