Sicoderus new sp. (near contiguous Vanin); O’Brien and Turnbow 2011: 9

Description: Length male, 4.5–6.0 mm; female, 4.7–5.8 mm. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 1.03–1.13x length elytra in male; 1.20–1.36x length elytra in female. Antennal insertion at about apical 1/ 3 in male, slightly beyond midlength in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, very small, very shallow on disc and laterally on flanks; no setae present. Elytra in dorsal view widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; no setae present. Strial punctures evident, small, shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male in middle near posterior margin with two small raised patches of fine setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 flattened medially in male, rounded in female. Legs with front femora with ventral margin with small sharp tooth, middle and hind femora each with small blunt tooth; tarsal claws lacking small basal tooth. Aedeagus (fi.g 48) widest towards apex, internal sac with pair of elongate thick basal sclerites subparallel. Female not dissected.

Material examined: 8 males, 3 females. Holotype male (CWOB), labelled DOMINICA: St. George Parish, Morne Trois Pitons National Park, Freshwater Lake Road, 2600’ , 13.VIII.1986, L. & C.W. O’Brien. Paratypes. Data as holotype (2 males, 2 females, CMNC, CWOB). 21.VIII.1986, L. & C.W. O’Brien (1 male; CWOB). 16.VIII.1986, L. & C.W. O’Brien (1 male, 1 female; CWOB). 25.VI.2004, C.W. & L. O’Brien (1 male; CWOB). St. David Parish, Emerald Pool Trail, 20.VI.2004, R. Turnbow (1 male; CMNC). Syndicate Falls Nature Trail, 1600’ , 28.VI.2994, C.W. and L. O’Brien (1 male; CWOB).

Derivation of species name: This species is named ‘lucidus’ after its shining, almost glabrous and impunctate appearance.

Comments: This species is very similar to S. delauneyi from Guadeloupe but S. lucidus has a small basal tooth on each tarsal claw, the setose patches on ventrite 1 of the abdomen of males are located at the posterior margin of the ventrite, and the basal sclerite of the internal sac of the male genitalia is different.
