03EB87C0E053FF94FC3FFDF0FD62F94E.taxon	diagnosis	Diagnosis. Dorsal integument finely pitted. Eye large, cornea bilobed. Ophthalmic somite anterior margin emarginate. Ocular scales separate. Carapace with anterolateral spines; median, intermediate, lateral, marginal and reflected marginal carinae present; median carina lacking branches of anterior bifurcation; lower posterolateral margin without obtuse angle. Mandibular palp absent or 1 – 3 articulate. Maxillipeds 1 – 5 each with epipod. Raptorial claw dactylus with 6 teeth; carpus with undivided dorsal carina; propodus unarmed distally; merus lacking outer inferodistal spine. Thoracic somite 5 lateral process a blunt diagonal projection, with small ventral spine. Thoracic somites 6 – 7 lateral processes triangular, faintly bilobed; anterior lobe considerably smaller than posterior lobe. Hook process of petasma apically blunt, longer than tube process. Abdominal somites 1 – 5 with distinct submedian, intermediate, lateral and marginal carinae; somite 6 with submedian, intermediate and lateral carinae. Telson with prelateral lobe; mid-dorsal surface with curved rows of pits; submedian teeth with fixed apices; postanal carina absent. Uropodal protopod with one lobe between terminal spines; inner margin crenulate. Type species. Squilla parva Bigelow, 1891, by present designation and monotypy. Etymology. Derived from the combination of the Greek for Michael (MΙΧ άλης) and the generic name Squilla, in honour of the late Michael Türkay for his career long contributions to carcinology. Gender feminine. Remarks. Ahyong (2005) showed S. parva to lie outside of Squilla sensu stricto, being probably more closely related to Gibbesia Manning and Heard, 1997. The presence of six rather than five teeth on the dactylus of the raptorial claw, the short and blunt rather than strongly produced lateral process of thoracic somite 5, and the blunt rather than spinular apex of the hook process of the male petasma, however, exclude S. parva from Gibbesia, justifying its removal to the new genus Michalisquilla. Michalisquilla parva n. comb. shares with species of Squilla a distinctly bilobed cornea, a unilobate lateral process of thoracic somite 5 and fixed submedian teeth on the telson. Michalisquilla, however, differs from Squilla as now restricted, in having the posterior lobe of the lateral process of thoracic somite 5 produced to a short, diagonal projection instead of a prominent lateral or anterolaterally produced spine, and a rounded instead of angular posterolateral margin of the carapace. Additionally, the hook process of the petasma is blunt in Michalisquilla instead of being produced to an apical spine, and the hook process of the petasma is markedly longer than, instead of about as long the tube process. Furthermore, Michalisquilla is the only squilloid in the Atlanto-East Pacific with variable segmentation of the mandibular palp, which may be absent or composed of 1 – 3 articles in adults. All species of Squilla, as well as all other Atlantic squilloids bear an apical spine on the hook process of the petasma, and lack variation in the condition of the mandibular palp. Crenatosquilla oculinova (Glassell, 1942) is the only other eastern Pacific squillid with an apically blunt process on the petasma, but it differs in numerous diagnostic features and is phylogenetically distant, as a member of the Meiosquilla Group, rather than Squilla Group (Ahyong, 2005). Although further revision of Squilla is required, the removal of S. parva to Michalisquilla renders Squilla homogeneous for the major diagnostic features of a distally pointed hook process of the endopod of male pleopod 1, presence of a 3 - articulate mandibular palp, and the lateral process of thoracic somite 5 as a single prominent anterolaterally produced spine.	en	Ahyong, Cara Van Der Wal and Shane T.

03EB87C0E057FF90FE43FC0BFE23FCAB.taxon	diagnosis	Diagnosis. Eye large; cornea width less than 1 / 3 CL, strongly bilobed, distinctly broader than and set obliquely on stalk. Ocular scales separate. Dorsal integument variously pitted. Mandibular palp 3 - articulate. Maxillipeds 1 – 4 each with epipod. Raptorial claw dactylus with 6 teeth, outer margin lacking basal notch; carpus dorsal carina undivided, smooth to irregular, not tuberculate; merus without outer inferodistal spine. Telson submedian teeth with fixed apices; prelateral lobe present; dorsolateral surface with curved rows of shallow pits; supplementary longitudinal carinae absent; ventral surface with short postanal carina. Carapace with anterolateral spines; median, intermediate, lateral, marginal and reflected marginal carinae present; median carina distinct, not interrupted at base of anterior bifurcation; branches of anterior bifurcation distinct, opening anterior to dorsal pit; posterolateral margin rounded. Thoracic somites 6 – 8 with distinct submedian and intermediate carinae. Thoracic somites 5 – 6 lateral processes bilobed. Thoracic somite 7 lateral process undivided. Abdominal somites 1 – 5 with distinct submedian, intermediate, lateral and marginal carinae; somite 6 with submedian, intermediate and lateral carinae. Abdominal somites 2 and 5 each with dark transverse dorsal patch. Uropodal protopod inner margin crenulate. Etymology. Named for Harry Vos, “ opa ” of the first author, for encouragement with her studies. The name is a combination of Vos and the generic name Squilla. Gender feminine. Type species. Squilla kempi Schmitt, 1931, by present designation and monotypy. Remarks. Ahyong (2005) showed by phylogenetic analysis that O. kempi and the type species of Oratosquilla, Oratosquilla oratoria (De Haan, 1844), were not closely related. Oratosquilla kempi was instead sister to a large clade of genera of the Oratosquilla group that included Oratosquilla sensu stricto deeply nested within. Moreover, apart from the similarly uninterrupted anterior bifurcation of the median carina of the carapace, O. kempi differs from other species of Oratosquilla in important diagnostic features. Given the distant phylogenetic position of O. kempi and its aberrant morphology in comparison to other species assigned to Oratosquilla, a new genus is justified, herein named Vossquilla. Vossquilla shares with Oratosquilla the uninterrupted anterior bifurcation of the median carina of the carapace, but differs in lacking an outer inferodistal spine on the merus of the raptorial claw, in having an irregular instead or distinctly tuberculate dorsal carina on the carpus of the raptorial claw, in having an undivided instead of distinctly bilobed lateral process of thoracic somite 7, and in having dark dorsal pigment patches on abdominal somites 2 and 5. Removal of Vossquilla kempi from Oratosquilla enables consistent diagnosis of the latter genus. Oratosquilla can now be clearly diagnosed by the combination of an uninterrupted anterior bifurcation of the median carina of the carapace that opens anterior to the dorsal pit, a tuberculate dorsal carina on the carpus and presence of an outer inferodistal spine on the merus of the raptorial claw, and the bilobed lateral processes of the thoracic somites 5 – 7.	en	Ahyong, Cara Van Der Wal and Shane T.

Abdominal somites 1 – 5 submedian carinae subparallel to weakly divergent. Abdominal somite 6 with small ventrolateral spine anterior to uropodal articulation; sternum posterior margin unarmed. Abdominal carinae spined as follows: submedian 5 – 6, intermediate (3 – 4) 5 – 6 (usually 4 – 6), lateral (2) 3 – 6, marginal 1 – 5. Telson about as long as wide to slightly wider than long; apices of intermediate teeth extending posteriorly to base of submedian teeth; prelateral lobe slightly shorter to slightly longer than margin of lateral tooth. Submedian, intermediate and lateral primary teeth each with smooth carina, that of lateral tooth extending anteriorly slightly beyond distal end of prelateral lobe. Marginal denticles rounded, submedian and intermediate denticles each with low dorsal tubercle or swelling; denticle formula: submedian 2 – 4, intermediate 6 – 8, lateral 1. Median carina interrupted proximally, with tubercle below posterior spine. Dorsolateral surface with rows of shallow pits; supplementary longitudinal carinae absent. Telson ventral surface with short postanal carina, extending posteriorly to about proximal one-fourth of distance to between anal pore and posterior margin; ventrolateral carina extending almost to base of lateral tooth. Uropodal protopod terminating in 2 slender spines; lobe on outer margin of inner spine narrower than adjacent spine, proximal margin concave; inner margin of inner spine crenulate; minute tooth proximal to endopodal articulation. Uropodal exopod proximal article with 7 or 8 movable spines on outer margin, distalmost spine reaching to proximal one-third of distal article; distal margin with 2 ventral spines, outer longer. Exopod distal article slightly longer than proximal article. Colour in life. Light grey-brown dorsally, darker middorsally. Carinae and grooves of carapace, submedian carinae, intermediate carinae, and abdominal somite 6 lateral carinae dark red. Mid-posterior margin of carapace yellow orange. Abdominal somite 2 and 5 with transverse black-brown patch between intermediate carinae, that of somite 5 on posterior half. Telson with median carina and prelateral lobe dark red; primary teeth with white tips and dark green carinae; telson surface with dark, irregular grey-green band across central one-third; submedian denticles white; intermediate and lateral denticles dull yellow-green. Uropodal protopod with whitish base colouration and dark yellow-green carinae, terminal spines white; endopod with speckled yellow distal half; exopod with white movable spines, with deep blue patch on distal half of proximal article; exopod distal segment diffuse blue in mesial half, diffuse white-yellow on lateral half. Antennules with black speckling.

Pereopods 1 – 3 translucent white, yellowish distally. Size. Male (n = 6) TL 28 – 113 mm, female (n = 5) TL 30 – 120 mm. Sun et al. (1998) reported specimens to 149 mm. Remarks. The series of V. kempi examined is largely consistent, with variation in abdominal spination that is largely size related. The intermediate carinae on abdominal somite 4 are unarmed in the smallest specimens (male TL 28, female TL 30 mm, NTOU), armed in all others. The prelateral lobes range from slightly shorter to slightly longer than the margins of the lateral teeth and the rostral plate may have a short median carina or dorsal tubercle, but is usually smooth dorsally; these variations appear unrelated to body size. The dorsal carina of the raptorial claw carpus in V. kempi has been characterized as irregularly tuberculate as in O. oratoria (e. g., Manning, 1971; 1995), though the condition in V. kempi is better characterized as smooth or irregular, but not distinctly tuberculate; the condition varies allometrically, being smooth in the smallest specimens, becoming increasingly irregular with increasing body size. In Oratosquilla, the dorsal carina of the carpus of the raptorial claw is distinctly, albeit irregularly tuberculate in adults, and less pronounced in juveniles. Distribution. Vietnam, China, Japan and for the first time from Taiwanese waters (Kinmen); intertidal to shallow subtidal depths.	en	Ahyong, Cara Van Der Wal and Shane T.
