Treatment

Xerolinus alutaceus ( Casey, 1890) , new combination

Blapstinus alutaceus Casey 1890: 423 (type

locality: Florida); Davis 1970: 90 (Florida,

Texas).

Diastolinus trinitatis Marcuzzi 1976: 127 (type

refers to Trinidad, Cuba]), 1984: 76 ( Cuba),

1988: 82 (key); Garrido and Gutiérrez 1996a:

2005: 152 ( Cuba). New synonymy.

Diastolinus (Diastolinus) trinitatis ; Marcuzzi

1986: 179.

Distribution. USA, Cuba.

Remarks. With the move of this species and Blapstinus dispar (Casey) (see below) to Xerolinus , a new genus has been added to the fauna of North America north of Mexico. Davis (1970) treated these two species as a pair in the

first couplet of his key to North American Blapstinus species and noted their isolation from other Blapstinus and similarity to each other. To accommodate this genus in the key to genera by Aalbu et al. (2002), the following changes should be made to Key Q. The two species will key to 7′, where an additional couplet should be added:

7a. Metathoracic wings developed; elytra free; body rather parallel-sided and flattened above; metaventrite long; elytral striae 7 and 8 reaching or approaching base of elytra independently; male genitalia typically with parameres simple, triangular in dorsal view, elongate and tapered.......... Blapstinus View in CoL

7a′. Metathoracic wings reduced; elytra fused together; body rounded laterally as a whole; metaventrite very short, much shorter than mesocoxal cavity; elytral striae 7 and 8 short anteriorly, not reaching base of elytra; male genitalia with parameres more broader and rounded apically ............................ Xerolinus
