Tomarus adoceteus Ratcliffe and Cave , new species
(Fig. 10-12)
Type Material. Holotype male, labeled “Roy Soc-
CIG Expdn./Little Cayman, BWI/Pirates’ Point/
house light/ 31.7.1975. R. R. Askew//BM 1981/342”
(hand written)/ our red holotype label. Allotype fe-
male with same data but date of 9.8.1975 and our
red allotype label. Single male paratype and single
female paratype with same data as allotype and
with our yellow paratype labels. Female paratype
labeled “WEST INDIES: Cayman Is./Grand Cay-
man/ VI-1992 coll. P. Fitzgerald/blacklight trap”
and with our yellow paratype label. Female
paratype labeled “Grand Cayman Is. B. W. I./
Georgetown / 16 Sept. 1973 /E. J. Gerberg//at black
light” and with our yellow paratype label. Holo-
type and allotype deposited at The Natural His-
tory Museum, London ( BMNH). Paratypes depos-
ited in the Florida State Collection of Arthropods,
Gainesville, FL ( FSCA) and the B. C. Ratcliffe col-
lection, Lincoln, Nebraska ( BCRC).
Holotype. Male. Length 22.1 mm; width 12.1 mm.
Color black. Head: Frons coarsely rugose, rugae Figure 10-12. Tomarus adoceteus Ratcliffe and Cave , new transversely curved; vertex at center with small, species. 10) Habitus. 11-12) Parameres.
subtriangular, smooth, shining area. Frontoclypeal
region with low, transverse tubercle either side of
middle, tubercles broadly separated, laterad of
clypeal teeth. Clypeus with surface sparsely, trans-
versely rugose; apex broadly truncate, with 2 small
teeth, teeth weakly reflexed. Interocular width
equals 3.5 transverse eye diameters. Antenna 10-
segmented, club subequal in length to segments
2-7. Mandibles with 2 apical teeth and a rounded
lobe at base. Pronotum: Surface on disc with
sparse, small punctures; punctures becoming mod-
erate in size and density on sides and anterior
fourth. Anterior margin with small, median tu-
bercle. A small, longitudinally oblong fovea present
behind tubercle, fovea about as wide as distance
between frontoclypeal tubercles, surface within
fovea rugose. Base lacking marginal bead. Elytra:
Surface shagreened, with moderate to large, weakly
ocellate punctures, punctures becoming larger lat-
erally; 3 pairs of double rows of punctures poorly
defined. Pygidium: Surface on center third nearly
smooth, with small, sparse punctures; surface else-
where densely rugopunctate. In lateral view, sur-
face convex. Legs: Protibia tridentate, basal tooth
slightly removed from others. Protarsus simple,
not enlarged. Apex of metatibia subtruncate, with
10 stout, short spinules (some broken off, sockets
visible). Apex of first tarsomere of metatarsus
subtruncate. Venter: Prosternal process long,
thick, columnar, setigerous at apex, apex longitu-
dinally oval; setae long, reddish brown.
Parameres: Fig. 11-12. The combination of nar-
row form, a long tooth projecting laterally at the Figure 13. Tomarus cuniculus (Fabricius) , habitus. midpoint of the shaft, and a narrowly elongate apex
is unique among Tomarus species.
Allotype. Female. Length 21.7 mm; width 11.7 mm. Color dark reddish brown. As holotype, except in the following respects: Head: Entire surface transversely rugose. Occiput at center lacking smooth, shiny area. Pronotum: Fovea reduced to a shallow, short, longitudinal depression. Pygidium: Surface on center third with sparse, large punctures. In lateral view, surface nearly flat. Legs: Protibia with trace of fourth, basal tooth. Left posterior leg missing.
Variation. Males (1 paratype). Length 22.5 mm; width 12.4 mm. The male paratype does not differ significantly from the holotype.
Females (3 paratypes). Length 20.0- 22.4 mm; width 10.3-12.2 mm. The female paratypes do not differ significantly from the allotype.
Etymology. From the Greek adoketus, meaning surprising or unusual. Used here as a noun in apposition, hence, Tomarus , the surprising one.
