Euchilofulvius yangon Yasunaga & Wolski , sp. n. Fig. 1

Diagnosis. Recognized by its rather ovoid body; generally coffee-brown basic coloration; slender antennal segment II which is shorter than basal width of pronotum and gradually thickened towards apex; notched posterior margin of pronotum; almost wholly darkened scutellum and clavus; irregular, fragmented pale patterns on anterior corium; and entirely brown tibia. Most similar to E. tibialis in sharing the similar dorsal coloration and rather flattened pronotal calli, E. yangon can be distinguished readily by the uniformly yellowish brown tibia. In E. tibialis the tibiae are bicolorous, with dark brown basal part and yellow apical part.

Description. Female: Body generally coffee-brown, sub-ovate, a little elongate, moderate in size; dorsal surface weakly shining, widely matte or shagreened, with uniformly distributed, short, silvery, scalelike setae. Head conical, slightly longer than wide; clypeus somber brown. Antenna brown; basal half of segment I and apical 1/3 of segment II dark brown; segment II gradually thickened towards apex, shorter than basal width of pronotum; segments III and IV yellowish brown, filiform. Labium shiny brown, reaching but not exceeding apex of metacoxa; apical half of segment I and almost entire segment II yellowish brown. Pronotum weakly shining and constricted at calli, speckled with reddish brown patterns; pleura fuscous, tinged with red along ventral margins; scutellum with a yellowish brown apex. Hemelytron widely fuscous, matte; corium with a thin, pale stripe along inner margin and with a fragmental, triangular pale macula anteriorly; base of cuneus irregularly yellowish brown; membrane dark smoky brown, with a small, yellow area close to apex of cuneus. Coxa dark brown; apical halves of meso- and metacoxae yellow. Leg dark brown; apex of each femur narrowly pale; metafemur with a subapical, pale spot posteriorly; all tibiae yellowish brown, partly tinged with red; all tarsi pale brown. Abdomen brown, partly mottled with dark maculae. Male: Unknown.

Measurements (♀): Total body length 3.16; head width across eyes 0.56; head length 0.59; vertex width 0.25; lengths of antennal segments I-IV 0.36, 0.82, 0.22, 0.30; labial length 1.20; mesal pronotal length 0.56; basal pronotal width 1.00; maximum width across hemelytron 1.16; and lengths of metafemur tibia and tarsus 0.92, 1.57, 0.26.

Etymology. Named for its occurrence in Yangon , Myanmar; a noun in apposition.
