Streblosoma Sars, 1872

Sars, 1872:410.— Hessle, 1917:210, Text-Fig. 61.— Hutchings & Glasby, 1986:110; 1987:222.— Hartmann-Schröder, 1996:527–528.

Synonyms: Grymaea Malmgren, 1866 (preocuped by a protozoa name); Eugrymaea Verrill, 1900 ; Pseudothelepus Augener, 1918 .

Type species: Grymaea bairdi Malmgren, 1866 , by original designation.

Diagnosis: Zero to five, commonly three, pairs of branchiae; when present, they begin on segment 2; lateral lappets present or absent; ventral shields from segment 2; nephridial papillae on segments 2–5; 40 or less pairs of notopodia from segment 2; chaetae smooth-tipped, limbate; pairs of neuropodia from segment 5; uncini avicular with button-shaped subrostral process.

Remarks: According to Holthe (1986b), only two species described are valid for the Grand Caribbean region: Streblosoma hartmanae Kritzler, 1971 , from Florida, and S. polybranchia Verrill, 1900 , from Bermuda. Hartman (1956, 1959) and Holthe (1986b) noticed that S. verrilli Treadwell, 1911 , from Florida, is a junior synonym of Thelepus setosus . Nevertheless, based upon the type specimen, this species belongs to Thelepus , being redescribed as Thelepus verrilli ( Treadwell, 1911) comb. nov., (see below). A third species, S. tenhovei sp. nov., is also described.

The original generic description by Sars (1872) stated that the genus may or may not have eyespots, and that uncini were uniserial (MF:1). However, uncini may have more than one tooth present above the main fang.
