Holotype Ƌ, Myanmar : Yangon : Pyay Road , National Museum Garden , 16°47'17.20" N 96°08'33.66" E , 180 m , with a coccid on leaf of Ziziphus mauritiana Lam. , 17 Oct 2015 , T. Yasunaga et al. ( AMNH _PBI 00380431) ( TKPM ) . Paratypes : 1 Ƌ 1 ♀ , same data as for holotype ( AMNH _PBI 00380432−00380433) ( TYCN ) ; 12 ♀♀ , same data, without USI labels ( AMNH , TKPM , TYCN ) . Diagnosis. Recognized by its small size; shiny, coffee-brown dorsum with paler lateral margins; enlarged compound eyes in males; comparatively wide pronotum with callus interrupted at midline; J-shaped paramere, medially with a slender, apically hooked dorsal process (flagellum). Very similar in the external morphology to B. castanea ; distinguished by above-mentioned diagnostic characters (in castanea , the body is larger and almost entirely pale yellowish brown, and the hooked process on the paramere more elongate). Fifth instar nymph ( Fig. 6 ): Recognized by its tortoise-shaped, rounded body, with narrowly lamellate lateral margin; shiny chocolate-brown basic coloration; well-polished, sub-glabrous dorsum; creamy yellow antennae and legs; and yellow lateral margins of pronotum and wing-pads.

Description. Male: Body generally coffee-brown, rounded, tortoise-shaped; dorsal surface shining, with uniformly distributed, simple, sericeous setae. Head shiny dark brown, with sparsely distributed, silky, erect setae; compound eye relatively developed; ocellus rather large, with diameter a little greater than thickness of antennal segment I. Antennae yellowish brown, generally short; segment II slightly clavate; segment III and IV tinged with red or brown. Labium yellow; first visible segment I darkened. Pronotum shining, finely punctate, with a pale reddish-brown, lamellate lateral margin rather rounded at humeri; callus somewhat concave (depressed?) medially; pleura reddish dark brown; scent efferent system fuscous; scutellum shiny fuscous, narrowly and transversely rugose, slightly arched. Hemelytron weakly roughened, shallowly punctate; anterior 2/3 of exocorium reddish or yellowish brown; membrane pale grayish brown. All coxae shiny chestnut brown; all legs yellowish brown. Abdomen uniformly shiny coffee-brown. Genitalia ( Figs. 25 , 32 ): Paramere large, J-shaped, pointed apicad, with a median process (flagellum) hooked apically. Female: As in male, but body larger and broader; compound eye smaller; clypeus usually pale reddish brown; antennae more slender and shorter; and lateral carinae of pronotum wider. Genitalia ( Fig. 26 ): Copulatory tube wholly membranous, winding. Measurements. ƋƋ / ♀♀ : Total body length 1.37−1.60 / 1.40−1.72; length from apex of clypeus to cuneal fracture 0.85−1.00 / 0.89−1.03; width of head across compound eyes 0.44−0.46 / 0.39−0.45; width of vertex 0.18−0.19 / 0.21−0.23; lengths of antennal segments I −IV 0.07−0.08, 0.29−0.30, 0.20−0.23, 0.18−0.22 / 0.06−0.07, 0.21−0.24, 0.16−0.21, 0.20−0.22; mesal length of pronotum 0.29−0.30 / 0.30−0.33; basal width of pronotum 0.77−0.83 / 0.81−0.87; maximum width across hemelytron 0.86−0.90 / 0.93−0.99; and length of hind femur, tibia and tarsus 0.41−0.45, 0.54−0.59, 0.14−0.15/ 0.39−0.43, 0.52−0.57, 0.13−0.15. Etymology. Named for its occurrence in Burma ( Myanmar ) ; a noun in apposition. Remarks. The present new species was found to co-exist with an unidentified coccid and a tingid, Monosteira sp. ( Tingidae : Tinginae ) on leaves of Ziziphus mauritiana Lam. (Rhamnaceae) ( Figs. 1, 4, 7 ). We assume that Bilia burma preys on the coccid, whereas any ecological relationship between the anthocorid and tingid remains unclear.
