Key to tribes of Lamiinae from Hispaniola

As discussed in Santos-Silva et al. (2019), many tribes in Lamiinae have been littered with such disparate genera to the point where they can no longer be defined based on any morphological features. Because of that, a key to tribes is impossible unless it includes many terminal taxa for each tribe in order to encompass the diversity of currently included genera. Global tribal revisions and synonymies based on all the genera are the only ways to remedy these issues. The key below can only be used for Lamiinae from Hispaniola, and caution is warranted especially for the couplets toward the end ( Apomecynini , Desmiphorini , and Pogonocherini ) which each contain heterogenous genera. Note that Devesa et al. (2019) just produced a key to tribes of Lamiinae of Cuba. Notable differences in the fauna of Hispaniola and Cuba include: Parmenini is represented in Cuba by three genera but absent from Hispaniola; Onciderini and Calliini are represented in Hispaniola by one genus each, but absent from Cuba.

1. Tarsal claws bifid or appendiculate................................................ 2 — Tarsal claws simple............................................................. 3

2(1). Elytra covered in dense vestiture of short, appressed pubescence, usually aposematically colored with orange and black............................................. Hemilophini

— Elytra with mixture of erect and depressed setae, usually without bright aposematic coloration Calliini

3(1). Head triangular from lateral view, with eyes far from antennal tubercle and not notched.................................................................... Agapanthiini

— Head usually not triangular from lateral view, but if so, then eyes notched and located adjacent to antennal tubercle.......................................................... 4

4(3). Antennal scape with a cicatrix at apex.............................................. 5 — Antennal scape lacking cicatrix at apex............................................. 6

5(4). Cicatrix well developed, heavily sculptured, mostly glabrous; tarsal claws divaricate........................................................................ Monochamini

— Cicatrix not prominent, mostly evident by a raised subapical margin, punctures obscured by setae; tarsal claws divergent.............................................. Pteropliini

6(4). Ant-like body with acute tubercle at elytral base, anteriorly elevated pronotum, and nearly divided eyes; size less than 3 mm .............................................. Cyrtinini

— Not ant-like and lacking acute tubercles at elytral base; mostly larger than 3 mm .......... 7

7(6). Pronotum quadrate, not rounded or tuberculate at sides, slightly longer than wide; antennal tubercles pronounced with deep, convex notch between them............... Onciderini

— Pronotum not as above, laterally rounded or tuberculate, often wider than long; antennal tubercles moderate, with only slight notch between them, at most............................ 8

8(7). Scape strongly clavate or tuberculate apically; humeri prominent.......... Acanthoderini

— Scape either conical and short or elongate and evenly enlarged apically; if slightly clavate, then humeri not produced......................................................... 9

9(8). Scape usually narrow, elongate, slightly and gradually expanded at apex, extending to about middle of pronotum or beyond (exceptions include Eneodes and Eugamandus which have shorter, thicker scape. Eneodes is recognized by the narrow, acute lateral pronotal projections and Eugamandus is recognized by the very small form with flightless morphology of unpronounced humeri and deflexed elytra posteriorly) Acanthocinini

— Scape short, usually slightly thickened at middle or evenly cylindrical, extending no further than anterior ¼ of pronotum...................................................... 10

10(9). Tarsal claws divaricate; pronotum with acute (but sometimes small) lateral tubercles; body and appendages usually with long, erect setae and short, depressed setae (exception includes Atimiola which is recognized by the pronounced punctures throughout the integument).................................................................. Desmiphorini

— Tarsal claws divergent; pronotum without acute lateral tubercles...................... 11

11(10). Prosternal process very broadly expanded between procoxae, broader than width of each procoxa, and closing them posteriorly....................................... Apomecynini

— Prosternal process narrow or expanded to less than width of each procoxa... Pogonocherini
