A New Species

A new species of gobiid, Hazeus ingressus sp. nov. (Teleostei: Gobiidae) is described from the Levantine coast of Turkey. The species probably originates from the Red Sea and represents the 11th alien gobiid species in the Mediterranean Sea. The new species is distinguished from its Indo-Pacific congeners by a combination of the following characters: no dark blotch on the first dorsal fin; caudal fin coloration; scales in lateral series 25-28 (modally 27); second dorsal fin rays I,8; anal fin rays I,8-9; predorsal scales ctenoid 7; short, stout gill rakers 2+8. This finding suggests that the Lessepsian invasion intensely continues with the inclusion of the known species as well as undescribed species.

A New Species

A new species of Propimelodus from the middle course of the rio Araguaia is described. Propimelodus araguayae, new species, can be distinguished from its congeners in having a conspicuous black dot on the base of the dorsal-fin rays (vs. a different pattern), large eyes (29.7-34.8% of head length and 62.7-74.7% of snout length vs. 14.5-21.1% and 31-44% in P. caesius and 9.5-19.7% and 17-38% in P. eigenmanni), anal-fin lobe present (vs. absent), premaxillary bone with three irregular rows of teeth (vs. 4-5 in P. caesius and 5-8 in P. eigenmanni), tip of anterior lateral process of basipterygium at the same level as the tip of the anterior medial process (vs. anterior lateral process extending beyond the tip of the anterior medial process), total number of vertebrae (43-44 vs. 47-48 in P. caesius and 45-46 in P. eigenmanni) and total number of gill rakers (28-33 vs. 20-23 in P. caesius and 19-20 in P. eigenmanni). This new species is possibly endemic to the middle course of the rio Araguaia.

Apogon fugax is described as a new species of cardinalfishes based on a specimen trawled off Jizan (Saudi Arabia), southern Red Sea, at a depth of 60–67 m; two specimens trawled off southwest of Ayeyarwady Delta, Myanmar, at 54–129 m; and two specimens trawled off Western Australia at 166 m. The new species shares characters with the modified ‘talboti look-alikes’ species group (i.e., A. caudicinctus, A. dianthus and A. soloriens) as well as A. rubrifuscus and A. deetsie (both previously also assigned to the latter species group) in having two supraneurals, 12 pectoral-fin rays (13 rays in A. soloriens), and an enlarged, membranous, ventral preopercular edge. Molecular phylogenetic analysis of the apogonid tribe Apogonini, however, revealed that A. fugax n. sp. and its most closely related congeners, A. deetsie and A. rubrifuscus, form a separate phylogenetic clade unrelated to that formed by the ‘talboti look-alikes’ species group that is part of the A. unicolor species group. Apogon fugax n. sp. is distinguished from the species of the ‘talboti look-alikes’ species group, A. deetsie and A. rubrifuscus, in having a large head (2.2–2.4 in SL versus 2.4–2.8 in SL), longer first dorsal-fin spine (1.7–2.0 versus 2.7–4.0 in length of the second spine), and in their gill rakers count (developed gill rakers on the first gill arch 11–12 versus 8–9 in A. soloriens and 13–20 in the other four species).

A new species of damselfish, Pomacentrus bangladeshius, is described from 3 specimens, 67–77 mm standard length (SL), collected from Saint Martin’s Island, Bangladesh. The new species is distinguished from congeners in having the following combination of characters: XIV, 13 dorsal-fin elements; II, 14 anal-fin elements; 19 pectoral-fin rays; 18–19 lateral-line scales; 17–19 gill rakers on first arch; body depth 1.68–1.88 (1.88) in SL; snout 4.17–4.60 (4.17) in head length; head 2.91–3.09 (3.08) in SL; a prominent notch present between preorbital and suborbital; olive to dark brown body color, dark brown premaxilla, and yellow iris with a narrow bronze eye ring. The new species inhabits shallow reef flats around rock and coral outcrops. Phylogenetic analysis also shows the clear divergence of P. bangladeshius from other genetically closely related congeneric species retrieved from GenBank and that it represents a separate lineage.

A New Species

Three specimens of a distinctive new species of congrogadin belonging to the basal lineage (Rusichthys) of the subfamily are reported here. The new species differs from its congener in having more dorsal-fin and anal-fin rays and more gill rakers on the outer surface of the first gill arch, in colour pattern, and in various osteological details (especially of the caudal skeleton). Rusichthys explicitus n.sp. is presently known from a single collection taken from 27 m off southwest Oman, whereas R. plesiomorphus is presently known from two specimens trawled in 140 m on the Lamu Banks off northern Kenya.

A New Species

A new species of shrimp-goby was collected at depths of 60–80 m off the southern Israeli Mediterranean coast. A unique ‘DNA barcoding’ signature (mtDNA COI and Cytb) revealed that it differs from any other previously bar-coded goby species clustered phylogenetically with the shrimp-gobies group, in which Cryptocentrus is the most speciose genus. A morphological study supported the assignment of the fish to Cryptocentrus and differentiated the new species from its congeners. The species is described here as Cryptocentrus steinhardti n. sp. However, the present phylogenetic analysis demonstrates a paraphyly of Cryptocentrus and emphasizes the need for revision of the genus based on integrating morphological and genetic characteristics. This finding constitutes the third record of an invasive shrimp goby in the Mediterranean Sea. An intriguing ecological issue arises regarding the possible formation of a fish-shrimp symbiosis in a newly invaded territory. Describing an alien tropical species in the Mediterranean prior to its discovery in native distribution is an unusual event, although not the first such case. Several similar examples are provided in the present article.

Navigobius kaguya is described on the basis of two specimens from the Ryukyu Islands, Japan, and Luzon, Philippines. It differs from other described species of the genus in live coloration, and in having: second dorsal-fin rays I,16; anal-fin rays I,16; pectoral-fin rays 21–22; gill rakers 5–6 + 17; and first dorsal fin weakly to moderately incised between spines, taller than second dorsal. It closely resembles an undescribed species from Bali and the Maldives, but differs in lacking an orange-red mid-lateral stripe. The possible placement of Navigobius khanhoa in Oxymetapon is discussed.

Garra orontesi, new species, is described from the Orontes River drainage in the eastern Mediterranean Sea basin in Turkey and Syria. It is distinguished from its congeners in the Mediterranean Sea basin and adjacent Mesopotamia by possessing 17–21 gill rakers on the lower part of the first gill arch, the pelvic-fin origin usually below the second branched dorsal-fin ray, 8½ branched dorsal-fin rays, usually 2–3 scales between the tip of the pectoral and pelvic-fin origins, and no tubercles behind the upper posterior eye margin. It is also distinguished by a minimum K2P distance of 2.7% in its COI barcode region against G. rufa, and 3.9% against the geographically adjacent G. turcica.

During a study aiming at the evaluation of the distribution of the soft-bottom community at different taxonomic scales, thefamily Syllidae was analysed to the species level. Among the identified material, one undescribed species belonging to the genus Sphaerosyllis Claparède, 1863 was found and two species constitute new reports for the Mediterranean Sea and for the Iberian Peninsula: Parapionosyllis cf. macaronesiensis Brito, Núñez and San Martín, 2000, and Syllis cf. mauretanica (Licher, 1999) n. comb., both only previously known from the subtropical Eastern Atlantic Ocean. The new species of Sphaerosyllis is mainly distinguished in having bulbous, small antennae, tentacular and dorsal cirri, small parapodial glands, with granular material, and compound chaetae with short blades. In this paper, we describe the new species and the specimens of the new reports.

Pimelodus multicratifer, a new species, is described from the rio Ribeira de Iguape basin. The new species differs from the other Pimelodus species by the following features: 26 to 30 gill rakers on the first branchial arch; a combination of three to six rows of dark spots regularly or irregularly scattered on the flanks and several small dark spots irregularly scattered on the dorsal surface of head, supraoccipital process, and sometimes on the dorsal and caudal fins; striated lips; maxillary barbels reaching between posterior tip of the pelvic-fin rays and posterior tip of the middle caudal-fin rays.
