Diagnosis.
This species is similar to
E. maculata
sp. nov.
, but can be distinguished from the latter by the following characteristics: 1) body pale brownish, while body brownish yellow in
E. maculata
sp. nov.
; 2) body larger (overall
26.1–27.7mm
), while body smaller (overall
24.4–24.8mm
) in
E. maculata
sp. nov.
; 3) pronotum brown, anterior margin yellowish, margins rounded, while pronotum yellow, only median with a spotted marking, margins angular in
E. maculata
sp. nov.
Description. Male. General:
measurements (mm): body length: 12.6–16.4, overall length: 26.1–27.7, pronotum length×width: 4.3–4.8×7.1–7.9, tegmen length: 22.5–24.4. Small, slender; body short, dark brown, tegmina hyaline, sparsely spotted (
Fig. 10
E–F).
Head:
brown to dark brown. Interocular space narrow; ocelli moderate, ocelli ridge straight. Frons flat, with two shallow dimples. Antennae dark brown. Clypeus small; anteclypeus yellow; post-clypeus brown to dark brown, with two yellow spots laterally. Labrum brown, apex white, hind corners round. Maxillary palpi and labial palpi dark brown (Fig. 15 K–L).
Pronotum:
brown, anterior margin yellow, but strongly maculated. Surface generally with small brownish pubescence and setae, anterior and lateral margins not distinctly setose; margins rounded, not distinctly angular, apex slightly convex and truncated, lateral borders round (Fig. 15 J).
Tegmina and wings:
exceeded the end of abdomen about
11.1–13.3 mm
. Tegmina hyaline, light brownish yellow, sparsely with small, scattered brown spots, several larger spots among the small spots. Wings hyaline, slightly dotted, venation distinct.
Legs:
dark brown, mixed with yellowish coloration. Surface covered with long yellowish-brown pubescence; tibial spines dark brown.
Abdomen:
short, smooth, dark brown, disorderly with some yellowish spots, a yellow trail longitudinally through the median of abdomen. Supra-anal plate well pubescent, apex protruded; two median sclerites large, cerci slender (
Fig. 29 A
). Subgenital plate brown but slightly yellowish for the exposed part, median usually slightly maculated, hind margin near straight, setose; styli small (
Fig. 29 B
).
Genitalia:
well sclerotized.
Left phallomere:
Anterior of L1 much protruded, round, with a long process toward left, two hind lobes strong; L2 thin, curved roundly, right end wrench-like; L3 straight, strong narrowed toward apex, the hook curved roundly or slightly rectangularly; pda short, paa bud like; L8 small.
Right phallomere:
large. R1M narrow, hind portion expand; R1L thin; R3 concave; R2 with two chunks, the outer one rounder, the inner one with median concave and narrowed (
Fig. 29
C–D).

Variation.
Males mainly vary in the following characters: 1) the density of brown spots in the hyaline area of pronotum; 2) the density of spots on the tegmen.
Etymology.
This species is named in honour of the Chinese entomologist Ping-Zhang Feng, who did much contributions to the knowledge of Chinese cockroaches.
