Genus Auletobius
Explanation of Names
Auletobius Desbrochers 1869
Numbers
9 described spp. in our area(1); speciose subcosmopolitan genus, with 7 subgenera worldwide(2)

The number of N-American species has been reduced to six by revision (3):
Auletobius ater (LeConte, 1876)
Auletobius cassandrae (LeConte, 1876)
Auletobius humeralis Boheman, 1859
Auletobius nasalis (LeConte, 1876)
(= A. laticollis Casey, 1866)
(= A. rufipennis Pierce, 1909)
(= A. mariposae Zimmerman, 1932)
Auletobius sanguisorbae (Schrank, 1798)
(= A. congruus Walker, 1866)
Auletobius viridis Pierce, 1909
Size
rather small (1.7 - 3.5 mm without rostrum)
Identification
Elytral puncturation partly to completely disordered, as a difference to most other Rhynchitinae.

N-American species divide in four sections, recently given genus rank:

A. antennae inserted basally on rostrum (Auletobius Desbrochers, 1869)
- A. sanguisorbae
B. antennae inserted at middle of rostrum (Pseudmesauletes Legalov, 2001)
- A. ater
antennae inserted at about 1/3 rostral length . . . . . . . . . .

D. antennal club unusually large, elytral punctures confused (Cesauletes Hamilton, 1983)
- A. nasalis (> 2mm, red to black, tends to have scutellar triangle spot)
- A. viridis (< 2mm, black with metallic luster)
E. antennal club normal, elytral punctures serial in tendency (Rhynchitobius Sharp, 1889)
- A. cassandrae (elytra with indistinct hair pattern)
- A. humeralis (elytra with humeral macula or all red, no hair pattern)

All Carribean, and Central American species belong in the last group. (4)
Range
most of the world; in our area, regionally in the US(1)(2)
Food
larvae develop in cut terminal leaf primordia of wide variety of hosts(1)
Remarks
our only representative of the cosmopolitan tribe Auletini Desbrochers 1908, that contains 5 genera(2);
respectively more, if several intrageneric taxa is given higher rank (4).
