Type Data. — Type locality: Amer. The holotype of Dermestes gleditsiae has disappeared. The insect at the Linnean Society in London is probably not the specimen used by Johansson and Linne for the original description and should not be considered the holotype. But there is no question about the identity of this species as it is the only species of palm bruchid occurring in the United States, and the name has been accepted for this species by bruchid researchers. No paratypes. Bruchus arthriticus. Holotype; deposited in Universitetets Zoologisk Museum, Copenhagen (UZMC). Bruchus fuscus. Holotype; deposited in Museum National d'Histoire Narurelle, Paris (MNHP).
Distribution . — (Fig. 3). Specimens examined, 2480. Bahamas, Bermuda, Cuba, Dominica, Dominican Republic, El Salvador, Guatemala, Honduras, Jamaica, Mexico (Campeche, Chiapas, Guerrero, Hidalgo, Michoacan, Nayarit, Oaxaca, Puebla, San Luis Potosi, Sinaloa, Sonora, Tamaulipas, Veracruz), Panama, United States (Alabama, Florida, Georgia, Louisiana, Mississippi, Texas).
Diagnosis. — Integument dark brown, sometimes slightly reddish (this is usually the color of specimens collected on Cuba), sparse white or yellowish-white pubescence. Males 7.2-12.1 mm, females 4.3-11.0 mm in length (pronotum-elytra); width of males 3.6-6.2 mm, females 2.2-5.4 mm, maximum thoracic depth of males 2.3-3.7 mm, females 1.5-3.6 mm. Eyes distant. Antennal segments 4-10 serrate, longer than wide. Disk of pronotum disk wider than long (length/width ratio mean 0.69). Metafemur almost twice as long as wide (length/ width ratio mean 1.94); pecten short with 7-12 denticles, denticle 1 acuminate and longer; prepectenal ridge longer than pecten, with 7-13 small acute spines. Metatibia with inner ventral carina not elevated. Pygidium wider than long (length/width ratio mean 0.74).
Males. — In tegumen t. Hirsute, base of each seta in a minute puncture (therefore minutely punctulate where setae have been removed), some structures glabrous. Gula, ventral part of gena, apical end of proepimeron (with golden setae lining the margin), metacoxa near trochanter, and part of mesal side of metafemur glabrous. Color. Body and appendages uniform dark brown, sometimes slightly
reddish.
Vestiture. Setae often lost on part of the body, possibly due to rubbing. Dorsal and ventral body surfaces with white or yellowish-white, medium texture, recumbent, moderately dense, uniform setae; antenna with minute white setae; sparse setae on elytron; sparse setae on ventral ridge of metafemur not covering pecten; protibia and mesotibia with coarse, golden, moderately dense to dense setae apically; metatibia lacking golden setae except a few golden setae inside apex of mucro; tarsomere 1 with moderately dense, golden setae, ventral side of tarsomere 3 with very dense, coarse, golden setae; pygidium not as densely hirsute as elytron.
Head. Shorter or about as long as pronotum; frons and vertex with median glabrous carina; ocular sinus vague or lacking; on dorsal side eyes distant; postocular lobe short; antenna shorter than elytron, segments 4-10 serrate, clearly longer than wide; maxillary palp segment 3 less than twice as long as segment 2 and somewhat wide; gena long; sides of submentum only feebly converging triangularly between eyes; on ventral side eyes distant.
Prothorax. Disk wider than long (length/width ratio mean 0.69); moderately punctate; all sides with strong, impressed, marginal line, anterior margin usually emarginate; angles produced, visible in dorsal view; medial dorsal surface usually flattened, sides depressed, sharply depressed toward apex, arcuate, narrowed to apex from slightly more than middle of side; angles of lateral margin at base sharply produced, angle more than 90°; posterior margin arcuate, feebly produced medially; strong lateral prothoracic carina complete, extending from base to apex. Protarsus 1 shorter and wider than metatarsus 1 (sexual dimorphism: not wider in females) . Prosternum completely separating procoxae, apex of prosternal process medium width.
Mesothorax and Metathorax. Scutellum small, subquadrate, often slightly longer than wide. Elytron with dorsal surface often slightly flattened between humerus and mesal margin, depressed towards sides and apex; humerus non-scabrous; striae punctate. Metafemur incrassate, maximum width closer to base, constricted toward apex, almost twice as long as wide (length /width ratio mean 1.94), ventral side with a pecten produced, short, straight, armed with 7-12 denticles; denticle 1 large, acuminate, closer to femoral apex than to base; following denticles decreasing in size; when
leg flexed tibia positioned on lateral side of pecten; prepectenal ridge longer than pecten, with 7-13 small acute spines; Metatibia arcuate, bending with an even arc (angle >90°); three strong ventral carinae, inner carina strong at base and mucro and moderately deep tibial furrow between inner and middle carinae, middle carina strong at base (weak at mucro in some specimens) and fusing with outer carina just before mucro, outer carina strong at base and mucro; lateral, dorsolateral, mesal and dorsomesal carinae obsolete; mucro medium size; tibial corona smooth, without spines; spur only slightly visible in lateral view. Mesotarsus 1 shorter, but only slightly wider than metatarsus 1. Mesosternal process vaguely slanting, projecting with less than 90° angle from body plane, apex usually feebly curved back towards plane of metasternum; metaspinasternum only feebly produced.
Abdomen. Sternum 1 about as long as remaining sterna. Pygidium punctulate, moderately convex in lateral view, wider than long (length /width ratio 0.74), wider at base than apex, at almost 90° angle to elytron, but most often not completely hidden by the elytra and thus partially visible in dorsal view.
Genitalia. Median lobe (Fig. 140) broad. Ventral valve long with sides forming a triangle with an obtuse angle. Armature of internal sac with two large, median, Y-shaped sclerites with one arm acute at apex and branched at less than right angle; two basal, straight or slightly curved serrated sclerites. Lateral lobes (Fig. 141) confluent, not separated, without cleft, apex with vague median notch, fold-like sinus (see Fig. 141) extending from notch to 0.5 length of distance apex to Kingsolver's band.
Females. — Similar to males, maximum thoracic depth usually slightly larger, protarsus 1 not as wide (sexual dimorphism). Armature of bursa copulatrix (Fig. 139) of two types: two apposed ventral sclerites, but widely separated at base, mushroom-shaped; and one dorsal sclerite, long, rodlike, wider at base, base of sac swollen, bulb like.

Caryobruchus gleditsiae is a species of beetle in the family Chrysomelidae (formerly Bruchidae). It lives in North and Central America and develops inside the seeds of palm trees. Adults grow to a maximum length of 11 mm (0.43 in), the size depending on the size of the seed it grew up in. The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.

Caryobruchus gleditsiae là một loài bọ cánh cứng trong họ Bruchidae. Loài này được Johansson & Linnaeus mô tả khoa học năm 1763.
