Encrasicholina pseudoheteroloba (Hardenberg 1933)

Summary:

A milky white anchovy with a broad silver stripe (almost as wide as the pupil diameter) from just behind the upper margin of the gill cover to the caudal-fin base, a narrow black stripe along the top of the silver stripe, a black occiput, and a silver cheek and gill cover. The species also has a long upper jaw (posterior tip extending beyond the posterior margin of the preopercle), and two unbranched rays in the dorsal and anal fins.
This species was previously considered to be a junior synonym of Encrasicholina heteroloba.

The species is pelagic in coastal waters.
Features	A species of Encrasicholina with the following combination of characters: dorsal and anal fins with 2 (rarely 1) unbranched rays; pseudobranchial filaments 16–24 (modally 19); gill rakers 19–26 (21) in upper series on 1st gill arch, 23–30 (27) in lower series, 44–55 (49) in total; gill rakers 13–18 (16) in upper series on 2nd gill arch, 20–27 (23) in lower series, 33–45 (40) in total; gill rakers 11–15 (13) in upper series on 3rd gill arch, 11–15 (13) in lower series, 22–29 (26) in total; gill rakers 9–13 (11) in upper series on 4th gill arch, 9–13 (11) in lower, 18–25 (22) in total; prepelvic scutes 3–7 (5); head short, length 22.8–27.5 % (mean 25.4 %) SL; upper jaw long, its posterior tip extending beyond posterior margin of preopercle; first unbranched dorsal and anal fin rays long, length 4.1–8.1 % (mean 6.0 %) and 2.5–5.5 % (mean 3.9 %) SL, respectively; D–P1 long, 101.6–137.2 % HL (mean 120.1 %) (Hata & Motomura 2017).
Remarks	This species was previously regarded as a junior synonym of the Shorthead Anchovy, Encrasicholina heteroloba, which also occurs in northern Australia.
Similar Species	Encrasicholina pseudoheteroloba differs from other species in the genus in having a long upper jaw (the posterior tip extends beyond the posterior margin of the preopercle) and two unbranched rays in the dorsal and anal fins.
