3B4F87C4FFA8FF99691C9948522050AA.taxon	diagnosis	Emended diagnosis: Integument membraneous; rostrum overreaching distal corneal margin; carapace with developed branchiostegal spine set on anterior margin; pleon with fourth to sixth somitess dorsally carinate, fourth somite posteriorly crenate, sixth somite posterodorsally straight; telson with posterior, triangular end-piece between apical spines, with two to three pairs of moveable dorsolateral spines and a single pair of apical spines. First maxilliped with exopod distally abruptly narrowing to a segmented distal part; second maxilliped greatly expanded, less than three times as long as broad; third maxilliped with subtriangular dactylus bearing a single strong spine at tip. First pereopod with a distal tooth on basis and ischium; fourth and fifth pereopods with dactyl slender, entire. Thelycum with a strong sharp medial ventrally directed tooth on S 6 or S 8, S 7 with a sharp protuberance projecting anteriorly far beyond this segment. Petasma with a fan-like serrate appendix on PI and PM greatly modified, PE not distally produced. Species included: Benthesicymus crenatus Spence Bate, 1881, Be. laciniatus Rathbun, 1906. Type species: Benthesicymus crenatus (subsequently designated by Spence Bate, 1888). Remarks: Two species of this genus were described, but most of the distinguishing characters (see undated summary in: Yang & Chan, 2019) may be linked to observed specimens being of a different age. Indeed, individuals of Be. crenatus are generally larger, have the hepatic spine and more teeth on the rostrum and on the crenation of the fourth pleura. These characters included in the key below should, therefore, be considered cautiously. The only reliable character is the morphology of the thelycum in adults: the large tooth is present on S 6 in B. laciniatus or on S 8 in Be. crenatus. Regrettably, in most reports, the thelycum is not illustrated with necessary accuracy and in detail (e. g. Yang & Chan, 2019). Geographical distribution: Central and North Pacific, North Atlantic, western Indian Ocean.	en	Vereshchaka, Alexander L., Corbari, Laure, Kulagin, Dmitry N., Lunina, Anastasia A., Olesen, Jørgen (2020): A phylogeny-based revision of the shrimp genera Altelatipes, Benthonectes and Benthesicymus (Crustacea: Decapoda: Benthesicymidae).

3B4F87C4FFABFF9B6B549FD9568F51B0.taxon	diagnosis	Diagnosis: Integument membraneous; carapace with developed branchiostegal spine set on anterior margin, no hepatic spine; pleon with fourth to sixth somites dorsally carinate, fourth somite posteriorly entire, sixth somite with posterodorsal curvature; telson with posterior, triangular end-piece between apical spines, with two to three pairs of moveable dorsolateral spines and a single pair of apical spines. First maxilliped with exopod distally gently tapering to tip; second maxilliped expanded moderately, more than three times as long as broad; third maxilliped with subrectangular dactylus, bearing several strong spines at tip. First pereopod with basis and ischium unarmed; fourth and fifth pereopods with dactyl slender, entire. Thelycum without median tooth on S 6 or S 8, S 6 with a pair of posterior setose protuberances, S 7 as a suboval scutum directed forward and covered with solitary sensory setae. Petasma with PM bearing long lashes set in numerous rows to form a grasping structure, PE not distally produced. Species included: Dalicaris altus (Spence Bate, 1881), comb. nov. Type species: Benthesicymus altus Spence Bate, 1881, by monotypy. Etymology: After the artist Salvador Dalí and from Greek καρίς, shrimp; a reference to a characteristic petasma, which resembles paintings of this prominent Spanish surrealist. Authorship of generic name: The phylogenetic basis for the erection of this genus was prepared by Vereshchaka & Lunina, who are thus solely responsible for making the generic name Dalicaris available. Geographical distribution: South Atlantic, Indo-West Pacific, eastern Pacific.	en	Vereshchaka, Alexander L., Corbari, Laure, Kulagin, Dmitry N., Lunina, Anastasia A., Olesen, Jørgen (2020): A phylogeny-based revision of the shrimp genera Altelatipes, Benthonectes and Benthesicymus (Crustacea: Decapoda: Benthesicymidae).

Type species: Benthesicymus investigatoris Alcock & Anderson, 1899, by monotypy. Etymology: From Mårran, the Groke, a fictional character in the Moomin stories by Tove Jansson, and from Greek καρίς, shrimp; a reference to a characteristic thelycum, which mirrors a negative picture of Mårran.	en	Vereshchaka, Alexander L., Corbari, Laure, Kulagin, Dmitry N., Lunina, Anastasia A., Olesen, Jørgen (2020): A phylogeny-based revision of the shrimp genera Altelatipes, Benthonectes and Benthesicymus (Crustacea: Decapoda: Benthesicymidae).

Diagnosis: Integument membraneous; carapace with developed submarginal branchiostegal spine set behind anterior margin, no hepatic spine; pleon with fourth to sixth somites dorsally carinate, fourth somite posteriorly entire, sixth somite posterodorsally straight; telson with posterior, triangular end-piece between apical spines, with two to three pairs of moveable dorsolateral spines and a single pair of apical spines. First maxilliped with exopod distally gently tapering to tip; second maxilliped expanded moderately, more than three times as long as broad; third maxilliped with subrectangular dactylus bearing several strong spines at tip. First pereopod with basis and ischium unarmed; fourth and fifth pereopods with dactyl slender, entire. Thelycum without median tooth on S 6 or S 8, no posterior setose protuberances on S 6, S 7 as a trapezoid scutum covered with tufts of sensory setae, no additional posteriorly directed scutum, S 8 with tufts of sensory setae extending from deep invaginations. Petasma as simple unarmed lamina, PE distally produced. Species included: Trichocaris bartletti (Smith, 1882), comb. nov., T. tanneri (Faxon, 1893), comb. nov., T. tirmiziae (Crosnier, 1978), comb. nov. Type species: Benthesicymus bartletti Smith, 1882. Etymology: From Greek τριχωτός, hairy, and καρίς, shrimp, a reference to the characteristic dense tufts of setae covering thelyca of the species included. Authorship of generic name: The phylogenetic basis for the erection of this genus was prepared by Vereshchaka & Kulagin, who are thus solely responsible for making the generic name Trichocaris available. Remarks: The species included are similar in the morphology of the copulatory structures, especially of the petasma, and in other external characters. A remarkable difference between species is related to the armature of the fifth pleonic somite. Petasma and thelycum of T. bartletti are illustrated by Pérez Farfante & Kensley (1997: fig. 27) under the name Bentheogennema intermedia (mistake in the figure caption). Geographical distribution: Three species show a distribution similar to parapatric: T. bartletti is known from the North and Central Atlantic and Indo-West Pacific, T. tanneri occurs in the East Pacific and T. tirmiziae has been recorded from the Indo-West Pacific. Thus, the only reported area where two species co-occur is the Indo-West Pacific (T. bartletti and T. tirmiziae).	en	Vereshchaka, Alexander L., Corbari, Laure, Kulagin, Dmitry N., Lunina, Anastasia A., Olesen, Jørgen (2020): A phylogeny-based revision of the shrimp genera Altelatipes, Benthonectes and Benthesicymus (Crustacea: Decapoda: Benthesicymidae).
