Euxiphydria pseudoruficeps
Okutani 1966
: 311, Figs 7, 8.
Diagnosis.
Length, 11.5 mm. Black except head entirely orange (
Fig. 24
). Forewing uniformly lightly infuscated; hind wing somewhat paler on basal half (
Fig. 23
).
Antenna
(
Fig. 29
) with 14 or 15 antennomeres; length of first four antennomeres as 1.0:0.3:0.8:0.4. Sculpture on frons consisting of straight to irregular carinae, not reticulate (
Fig. 28
). Head from above gently rounded behind eyes, distance behind eyes much longer than eye length (
Fig. 27
). Malar space narrow between eye and antennal groove, much shorter than width of groove (
Fig. 28
). Axilla and mesoscutellum with
irregular
longitudinal carinae, posterolateral and posterior sides smooth and shiny (
Fig. 26
). Mesepimeron with long, distinct, almost parallel carinae (
Fig. 25
). Hind basitarsomere subequal to length of remaining tarsomeres combined. Length of sheath slightly shorter than length of basal plate. Male unknown.

Specimens examined.
Holotype. Female, labeled "[FORMOSA] Tattaka, 31.May.1965, T.
Shirozu"
(KU).
Okutani (1966)
stated "31-v-1965, Sungkang, Formosa, T.
Shirozu
leg.". TAIWAN: "[Taiwan], Sungkang, 2000m, Nan-tou-Hsien, 19-25.iv.1987, C. C. Lo (1 ♀, NSMT).
Discussion.
The two specimens examined are very similar, though the carinae on the frons and mesoscutellum of the holotype are somewhat more distinct than in the other specimen.
