Passalus (Pertinax) antillarum ( Arrow, 1907)

( Fig. 11 View FIGURES 10 – 13 )

Type locality. Grenada: Windsor, Chantilly, and Grand Etang.

Diagnosis. 20.5–22.5 mm total length. Clypeus hidden below frons, not visible dorsally, with anterior angles well developed, larger than medio-frontal tubercles. Frons border with weak notch, without secondary mediofrontal tubercles. Frontal fossae glabrous. Medio-frontal tubercles developed, not joined to interior tubercles. Internal tubercles as large as medio-frontal tubercles. Central tubercle of MFS with apex not free; basolateral tubercles weak. Antennal club trilamellate, with short lamellae. Apex of lacinia bidentate. Mentum with medial base swollen and glabrous. Prosternal process rhomboidal, acute. Mesosternum glabrous with scars marked and elongate. Antero-lateral metasternum and lateral groove glabrous, disc delimited by sparse punctures in posterior area. Humeri and epipleura glabrous.

Material examined. Nine specimens. GRENADA: no more locality data, xi–xii.1912, R. Thaxter (1 UVG).

Saint Andrew Parish: Grand Etang, 8.I.1969, col.: R.T. Bell/ Passalus (Pertinax) antillarum (Arrow) Schuster Det. 2003 (1 IEXA; 1 UVGC); same locality, 12.I.1969, col.: R.T. Bell/ Passalus (Pertinax) antillarum (Arrow) Reyes- Castillo, det. 82 (1 IEXA); same data as anterior/ Passalus (Pertinax) antillarum (Arrow) Schuster Det. 1981 (2 UVGC); Rd. end to Mt. St. Catherine, 23.ii.1990, at night, in rotting log, R.E. Woodruff, A. Thomas, J. Telesford (1 UVGC). Saint David: Mt. Sinai, 20.xii.1981, Chalumeau (2 UVGC).

Distribution. Grenada ( Arrow 1907, Hincks & Dibb 1935, Ivie & Gillogly 1998).

Comments. Arrow (1907) cited Windsor, Chantilly, and Grand Etang as the type locality. Hincks & Dibb (1935), Blackwelder (1944), and Ivie & Gillogly 1998 only cited Arrow (1907), without recording any specimens. Therefore, the specimens cited in this paper are the only specimens known other than the type series. We consider this species as endemic to Grenada, being the only endemic passalid to the Lesser Antilles.
