Trogoderma aritae nov.sp. (figs 1-5)

T y p e m a t e r i a l: Holotype (♀): Honduras, La Paz, San Pedro de Tutule, La Chanchera, 14.xi.2020, 14°14´4.997´´N 87°51´19.745´´W 1419 msnm, on tree Pinus oocarpa , coll. Gabriela Arita. Holotype missing anterior legs.

D e s c r i p t i o n: Female: Body measurements (in mm): Total body length – 2.75. Head: maximum width across eyes – 0.30. Pronotum: maximum width – 1.33. Elytra: maximum width – 1.44. Small and oval (fig 1) species, with conspicuous colour patterns. Black and orange on dorsal surfaces and black on ventral surfaces (figs 1-3); legs paler, light brown; scape, pedicel and antennomeres light brown.

Head coarsely puncturated with long yellow setation. Palpi entirely yellowish-brown; setation on mentum dense. Eyes small, not overlapping lateral margin of head from dorsal view. Ocellus on front present. Antennae (fig. 5) composed of 11 antennomeres, antennal club of 6 antennomeres. Pronotum coarsely puncturated alike head with short yellow setation; lateral and anterior margins continuous, regularly rounded, posterior margin conspicuously bisinuate, anterior angles not visible from above. Mesonotum heavily sclerotized; scutellum very small, triangular, finely puncturated alike pronotum and head, without setation. Metanotum robust, more weakly sclerotized as mesonotum. Mesometasternum black with short yellow setation. Mesosternal process coarsely puncturated, long. Elytra coarsely puncturated; black with one transverse, orange band and orange apical spot (figs 1-3) covered by white setation. Elytral epipleuron entirely black with white setation. Legs brown with short white and yellow setation; tibiae without thorns. Abdominal ventrites with short yellow setation (fig. 4). First visible abdominal ventrite with distinct oblique discal striae and robust, heavily sclerotized median tubercle. Pygidium brown with short, yellow setation.

D i f f e r e n t i a l d i a g n o s i s: The Central America contains following countries: Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama. The genus Trogoderma recorded in Central America includes 10 species (see table 1), nine species were introduced within stored products or other comodities. The new species is similar to T. beali MROCZKOWSKI, 1968 ( Costa Rica), but differs from it by the bicolorous elytral cuticle (beali – elytral cuticle is only black). Other similar species as T. grassmani BEAL, 1954 ( Mexico, U.S. A) and T. okumurai BEAL, 1964 ( U.S. A) differ from the new species by the structure of antennae and elytral colour patterns (figs 6-7).

E t y m o l o g y. The species epither is patronymic. The new species is named after the collector of the new species Gabriela Arita ( Honduras).
