Description

Metapenaeus intermedius (Kishinouye, 1900)

(Figs. 4, 8d)

Penaeus intermedius Kishinouye 1900: 21, 1 unnumbered textfig. (type locality: Japan).

Metapenaeus intermedius — Miquel 1982: 96, figs. 39-40.— Yu & Chan 1986: 133, 1 unnumbered fig.— Lee et al. 1999: 445.

Material examined. Kaohsiung City, Neiwei market, 2019 Jun, 1 female cl 25.6 mm (NTOU M02329). Pingtung County, Donggang fishing port, 6 Aug 1996, 1 female cl 35.1 mm (NTOU M02330); 9 May 2018, 3 females cl 27.3-35.8 mm (NTOU M02331). Penghu County, 10 Oct 1984, 2 females cl 23.4, 25.3 mm (NTOU M02333).— Magong fishing port, 1 Apr 2013, 2 females cl 33.6, 36.5 mm (NTOU M02332).— Third fishing port, 8 Jun 2013, 1 male cl 26.9 mm, 1 female cl 30.4 mm (NTOU M02334).

Diagnosis. Rostrum with 8–11 (excluding epigastric tooth) teeth along entire dorsal border, generally straight and more or less extending to middle of distal segment of antennular peduncle. Pereiopod I with distinct ischial spine. In males, basial spine of pereiopod III not particular elongated, merus of pereiopod V with basal notch accompanied by a carinated tubercle. Telson armed with 3 pairs of large movable lateral spines. Male petasma with distomedian projection as triangular flap and slightly overreaching tip of spiniform distolateral projection. Female thelycum with anterior plate bearing 2 elongated subquadrate protuberances; coxal projections of pereiopod IV extremely elongate, flat and extending onto lateral plates; lateral plates with posteromedian ogival boss and posterolateral margins elevated into ridges.

Coloration. Body yellowish grey and distributed with dense dark dots. Rostrum dark brown. Antennal flagella reddish. Uropods red margined and with distal parts bluish to dark blue.

Distribution. Indo-West Pacific from the Andaman Sea to Japan, Malaysia and Indonesia, intertidal to 130 m deep (Miquel 1982; Pérez Farfante & Kensley 1997; Chan 1998).

Remarks. Metapenaeus intermedius is mainly found in southern Taiwan and Penghu. This species can be readily distinguished from the other species of the genus in Taiwan by the telson bearing three pairs of large movable lateral spines (Fig. 4e).
