Abdomen

Male terminalia
: Only one male specimen, the
holotype
, was available, and much of its abdomen was lost. The following describes the parts that are associated with this specimen. T9+ect triangularshape, anterior margin rounded; callus cerci round, with ca. 30 trichobothria (
Fig. 17
A); S8+9 fused, with posterior margin slightly bilobed in ventral view (
Fig. 17
B).
Male genitalia
: Gonarcal bridge U-shaped; lateral apodemes ovate (lateral view), with bent, digitiform horn (
Fig.17
C–E); arcessus covered with dense black microtrichiae dorsally.
Female terminalia
(
Fig. 18
): A1–8 with oval spiracles. T9+ect with posterior margin curved, with cleft beneath callus cerci; callus cerci round with ca. 30 trichobothria. S7 trapezoidal, slightly tapered distally, with dorsal margin sinuous; surface covered with dense, long setae; ratio of ventral margin length: anterior margin height ~ 2.4: 1. Spermatheca pillbox-shaped, ventral impression deep, spermathecal duct very long, ca. 3.9 times height of spermatheca and velum (
Fig. 18
C–D). Subgenitale rectangular, lobate dorsally, slightly extended basally (

Species relationship
.
U. nigromaculifrons
sp
.
nov
.
is similar to
U. favrei
sp
.
nov
.
Both species have head with golden coloration, genae and basolateral clypeus black; vertex with a pair of broad, cresent- shaped, brown marks, and pronotum with dark brown or reddish brown lateral marks, but
U. nigromaculifrons
sp
.
nov
.
, has a prominent circular black mark on the frons and a forewing with most of its crossveings black, whereas in
U
.
favrei
, the face has red marks laterally, the frons has a small black spot, and most of crossveins on the forewing are pale.
Etymology
. The name comes from the Latin words:
nigro =
black,
maculi
= spot, and
frons
= face; it refers to the rounded black spot on the frons.
