Herklotsichthys castelnaui (Ogilby 1897)

Distinguished from most other Australian Herklotsichthys by lacking spots on the flank and lacking elongate wing-like scales underneath pre-dorsal scales. Most closely resembles H. blackburni but has more lower gill rakers. Separated from H. gotoi and Herklotsichthys species C by having 3 distinct dark lines upper flank. Upper caudal tip black; dorsal fin with distinct pale band.

Oviparous (Ref. 205).

Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 19; Analspines: 0; Analsoft rays: 17 - 21; Vertebrae: 41 - 42

Schooling species found in estuarine and coastal marine waters (Ref. 33617, 75154). Adults undergo spawning migration from coastal waters into upper reaches of estuaries during summer and autumn (Ref. 33617).

The material of Nematalosa obtained by the 1975 Fly survey represents the first extensive samples of this genus from central-southern New Guinea. Only five specimens from this area, one from Lake Murray and four from the Digul, were available for examination by Nelson and Rothman (1973) in their revision of Indo-Pacific Dorosomatinae. They identified these five specimens as N. erebi (Günther, 1868), to the synonymy of which they tentatively referred N. papuensis (1973:152–158). T. Wongratana has examined some of my specimens from the Fly and finds they differ from N. erebi, the holotype of which he has studied.

The Fly Nematalosa pose an unusual systematic problem. The large specimens from Fly 75–6 fall into two fairly clear-cut groups, one with short gill rakers and long gill filaments, the other with long gill rakers and short gill filaments. The two kinds were first distinguished in the field not by the gill rakers, but by the lower jaw, which is longer and more up-turned in those with long gill rakers. Representatives of both kinds were repeatedly taken together in the same gill net, under circumstances indicating that they had been schooling together. The coloration of live fish, overall silvery with an orange or golden opercle, appeared identical in both kinds. As a consequence of these observations, efforts were made to catch more Nematalosa, all of which were preserved. The specimens from Fly 75–5, –20, and –27 all have more or less short gill rakers, but those from Fly 75–22, –24, and –25 include both kinds, and at Fly 75–25 many of the specimens are intermediate. The variation exhibited by the gill rakers is in fact more complicated than indicated by these remarks, since the number of gill rakers increases markedly with growth, and is extremely variable among individuals of any given size. Thus in two 55-mm specimens with short gill rakers from Fly 75–25, one has 90 gill rakers on the lower limb of the first gill arch, the other 160! This material is being studied by T. Wongratana.
