A new species of Trogoderma from Honduras
(Coleoptera, Dermestidae, Megatominae)
Jiří HÁVA & José Francisco GARCÍA-OCHAETA
Abstract:Trogoderma aritae nov.sp. from Honduras is described, illustrated and
compared with similar species. A list of Trogoderma species known from Central
America is given.
K e y w o r d s : Taxonomy, new species, Coleoptera, Dermestidae, Trogoderma,
Honduras.
Introduction
The dermestid genus Trogoderma DEJEAN, 1821 currently contains 163 species and
subspecies distributed worldwide (HÁVA 2018, 2019, 2020), From Central America 10
species have been recorded (BEAL 1954, 1960, 1964, HÁVA 2015, SILVESTRE HERNÁNDEZ
2015, HAGSTRUM & SUBRAMANYAM 2009, DÍAZ 2018, BAHA 2019, GARCÍA-OCHAETA &
HÁVA 2019, OIRSA 2020). As a result of Gabriela Arita's research on the inventory of
insects associated with the southern pine beetle (Dendroctonus frontalis ZIMMERMAN) in
Honduras, the following new species of Trogoderma was collected.
Material and Methods
We measure total body length as a distance from anterior margin of pronotum to the
posterior margion of elytra.
The label data of the material examined are cited verbatim, including possible errors.
Studied material is deposited in the Universidad del Valle de Guatemala Collection of
Arthropods (UVGC), Guatemala. Type specimen of the species here described is provided
with a red, printed label with the following text: "HOLOTYPE Trogoderma aritae nov.sp.
Háva & García-Ochaeta det. 2021".

Genus Trogoderma DEJEAN, 1821
Type species: Anthrenus elongatulus FABRICIUS, 1801
R e c o g n i t i o n . Body subparallel to ovate, moderately to strongly convex, with
recumbent to erect setation. Head with median ocellus. Antennae with 11 antennomeres,
antennal club with 3-9 antennomeres. Antennal cavity closed. Prosternum forming a

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.
Description: 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. Meso-
metasternum 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.
Male unknown.

Differential diagnosis: 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).

Correction
In the OIRSA (2020) a table of synonyms for Trogoderma granarium is given. However, this table is
partially erroneous because it contains many valid species. Correct synonyms for T. granarium are
only four: T. quinquefasciata LEESBERG, 1906, T. khapra ARROW, 1917, T. koningsbergeri PIC, 1933
and T. afrum PRIESNER, 1951 (HÁVA 2015, 2020).
