(California Academy of Sciences (CASC), San Francisco, California, United States of America). Paratypes – three males, two females, same data as holotype (one male, one female (Museu de Zoologia, Universidade de São Paulo (MZSP), São Paulo, Brazil); two males, one female (Larry G. Bezark, collection, Sacramento, California (LGBC), United States of America)); two females with verbatim label data: 1 km W Cosanga, 4.IX.1998, F. T. Hovore col. (CASC).

Etymology. Blabia alboseta is named for the long, white setae on the elytron.

Remarks. Blabia alboseta differs from B. costaricensis Breuning, 1943, and B. similis (Breuning, 1940) as follows: antenna shorter, surpassing elytral apex by about three antennomeres; basal antennomeres not ringed with light colour. In B. costaricensis and B. similis the antenna are longer, surpassing elytral apex, by at least four antennomeres, the basal antennomeres are ringed with light colour, and the apical spine of the elytron is distinctly shorter.

Blabia alboseta can be included in the alternative of couplet 10 from Martins and Galileo (Reference Martins and Galileo1995) (translated; modified):

Alloblabia Galileo, Santos-Silva, and Bezark, new genus

Type species. Alloblabia praecipua new pecies, current designation.

Etymology. Allo, Greek prefix=different. In reference to the different shape of the scape when compared with species of the genus Blabia. Feminine gender.

Description. Male. Frons slightly wider than long. Antennal tubercles elevated. Eyes coarsely faceted; upper eye lobes with four rows of ommatidia. Dorsal surface longitudinally concave from antennal tubercles to anterior margin of prothorax (this area narrowed towards prothorax). Antenna with 11 antennomeres, distinctly longer than body. Scape elongate, sinuous, enlarged towards apex, somewhat projected at outer apex, rounded at inner apex, somewhat flat dorsally on anterior two-thirds; with distinct, conical, tubercle on distal one-third; without dorsal cicatrix at apex. Antennomere III slightly longer than IV. Prothorax, excluding lateral tubercles, about as long as wide; sides with large, acute tubercle about middle; dorsal surface of tubercle with another small, rounded tubercle. Pronotum with five distinct tubercles. Procoxal cavity closed behind. Elytron elongate, somewhat scabrous, with central-basal crest; apex truncate, with outer angle projected; surface with thick, sparse setae. Femur subclavate.

In these genera the scape is uniformly elongate towards apex, not sinuous and without a dorsal tubercle. It differs from Malthonea by the eyes also being coarsely faceted (finely faceted in Malthonea).

Alical Galileo, Santos-Silva, and Bezark, new genus

Type species. Alical tuberculatus new species, current designation.

Etymology. Alical, anagram of the genus-group name Callia. Masculine gender.

Description. Eyes finely faceted; lower eye lobes large, about 1.5 times genal length. Antenna surpassing elytral apex in male, reaching elytral apex in female. Scape gradually enlarged towards apex; with apical cicatrix. Antennomeres III–VIII cylindrical, moderately thick; antennomeres IX–XI gradually narrowed towards apex (together, uniformly narrowed); antennomere III about as long as scape and antennomere IV; antennomeres without dense fringe of setae. Prothorax transverse, with small, acute tubercle laterally. Mesosternal process with single, longitudinal tubercle. Elytron convex, without carinae, not depressed along suture, parallel-sided, pubescent; humerus slightly projected forward; elytral length about 2.5 times humeral width; apex rounded; with thick, erect setae throughout. Apex of metafemur slightly surpassing apex of ventrite II. Metatarsomere I shorter than II+III; basal tooth of claws developed.

Remarks. Alical differs from Callisema Martins and Galileo, 1990, by the elytron not being depressed along the suture, and by the antennomeres being thicker. In Callisema the elytron are depressed along the suture and the antennomeres are slender. It differs from Anapsicomus Galileo and Martins, 1988, primarily by the scape with a cicatrix at apex, and the mesosternal process being tuberculate (without cicatrix and not tuberculate in Anapsicomus). It can be separated from Ardecomus Galileo and Martins, 1988, by the mesosternal process being tuberculate (not so in Ardecomus), and by ventrite V in male being truncate (rounded in Ardecomus). It differs from Zenicomus Thomson, Reference Thomson1868, by the scape not being tumid at the apex (tumid in Zenicomus); by the basal antennomeres being cylindrical (enlarged towards the apex in Zenicomus); by the pronotum not being tuberculate (tuberculate in Zenicomus), and by the mesosternal process being tuberculate (not tuberculate in Zenicomus). It can be separated from Micatocomus Galileo and Martins, 1988, primarily by the rounded elytral apex (distinctly truncate in Micatocomus). Finally, it differs from Callia Audinet-Serville, 1835, by the scape having an apical cicatrix (absent in Callia), and the mesosternal process being tuberculate (not so in Callia). It differs from the genera with an apical cicatrix on the scape by the mesosternal process being tuberculate (not tuberculate in Mimolaia Bates, 1885, Ardeocomus Galileo and Martins, 1988, Graminea Thomson Reference Thomson1864, and Cicatricallia Martins and Galileo, 2012).

Alical can be included in the alternative of couplet 16 from Galileo and Martins (Reference Galileo and Martins1991) (translated):

Etymology. Piola schiffi is named after Nathan M. Schiff, who has accompanied the third author on trips to both the New World and Old World tropics for over 25 years.

Remarks. Piola schiffi differs from P. rubra Martins and Galileo Reference Martins and Galileo1999 as follows: pronotal longitudinal band with pale yellow pubescence; elytron without large glabrous areas; elytron without large, dense areas of white pubescence. In P. rubra the pronotal band has yellow pubescence, the elytron have large glabrous areas and white pubescence covers large areas.

The key to species of Piola by Martins and Galileo (Reference Martins and Galileo1999) is problematic, because in the first alternative of couplet 1, the scutellum was described as glabrous, leading to P. rubra, or pubescent, leading to the other species. However, the pubescence in the holotype of P. rubra was lost, because the typical form has the scutellum distinctly pubescent (see Bezark Reference Bezark2016). Hence, we provide a new key to include both the old and the new species.
