Description

Rostrum absent; carapace rounded and spiny; anterior margin armed with irregular-sized spines; median area behind frontal horns generally with a longitudinal row of three spines only (Fig. 3 a); cervical groove distinctly wider than posterior marginal groove; antennules with flagella longer than peduncle; antennular plate at basis of antennae bearing one pair of well-separated principal spines and some scattered spinules (Fig. 3 b); ventral surfaces of distal two antennal segments, each with a row of two equal-sized large spines only (Fig. 3 d). First 4 pereiopods without pincers; Thoracic sternum with two strong submedian protrusions (Fig. 3 c). Abdominal tergites with a complete transverse groove joining the pleural groove; pleura only with that of second somite sometimes bearing spinules (Fig. 3 e). Colour: body dark brown to indigo, covered with numerous white spots and markings; lateral carapace with two longitudinal white stripes running along the entire carapace; inner surface of antennal peduncle (including stridulating pad) and antennular plate pink; antennal flagella dorsally brown, ventrally whitish to pink; antennules with peduncle dark brown but laterally white, outer flagella dark brown and inner flagella entirely whitish; legs striped with conspicuous white lines; abdomen covered with numerous medium-sized white spots. Soft part of tail fan orange-brown with distal margin whitish. Pleopods somewhat greenish with white margins.

Diagnosis

Examined materials. 1 female: Malaysia; Sabah; Semporna; 8 December 2019. Carapace length 47.3 mm, carapace width 40.44 mm, total length 145 mm, weight 129 g. (Fig. 2 )

Molecular characterization

The best model of the COI fragment dataset in this study estimated by jModelTest selected with corrected AIC was the GTR+I+G model (General Time Reversible Model with invariant sites and non-uniform evolutionary rates or gamma distribution). Overall, the ML tree of COI comprised two major clades (Clade I and Clade II) as shown in Fig. 4 . The collected specimen in this study grouped in Clade I together with P. femoristriga (MG062676) from Indonesian waters, with strong bootstrap value of 96%. Panulirus femoristriga grouped as sister species with P. marginatus + P. bruneiflagellum , but with weak bootstrap value (<50%, not shown in the tree). The p-distance within P. femoristriga was 0.8%, while the p-distance of P. femoristriga with molecular ( P. marginatus and P. bruneiflagellum ) and morphological ( P. longipes longipes and P. longipes bispinosus ) closely-related species were more than 10% (Table 1 ). Accordingly, the spiny lobster in this study is confirmed as P. femoristriga . For information and record, a new sequence dataset is uploaded to GenBank, with the accession number: OK032600.

Distribution

Based on Table 2 , the distributions were confirmed in Christmas Island, Wallis and Futuna Island, Marquesas, north-western Hawaiian Islands, Galapagos Islands, Taiwan, Philippine, Indonesia and Japan. Fig. 5 shows the status of Panulirus femoristriga in a world map. This study expands its global distribution by including Malaysia. However, some of the distribution localities are listed as "to be confirmed" due to the uncertainties or “invalid” after the revision on the new taxonomic restructuring by Chan and Ng (2001), based on the morphological descriptions. The results indicated that the occurrence of the P. femoristriga needs a major re-confirmation in some localities or be removed.
