Gebien (1937; 1938-42; 1942-44) and Blackwelder (1945), but the distributional information in these is scarcely changed from the Champion (188!~3; 1889-93) fauna! work. In general, no local fauna! lists seem to haYe
been made for any region in ::\Iesoamerica. The leYel of knowledge is especially low for the Pacific Coast of 1\Iexico, which had been largely
unsamplcd at the time the Biología was written, except for limited areas
around the Gulf of Tehuantepec, Acapulco and Mazatlan. The paYed
highway betwcen Guaymas ancl Tepic was not completed until almost
1960 and that between Puerto Vallarta and Acapulco remained unpavcd
for ~everal more years. Consequcntly, revisionary papers seldom contain
many specimens citations for pacific coastal localities (e.g., Triplehorn.
197~: Campbell 1966; Doyen, 1984a), often referring to specimens collectecl
lOO years prcvious. For these rcasom it is appropriate to present a list
of the Tenebrionidae which have been collected at the Estación de
Biología Chamela of the Universidad Autónoma ele México. The Estación is located near the settlement of Chamela, approximate1y 125 km
north\\·est of ::\Ianzanillo (Bullock, 1987). It is situated less than ~ km
from the seacoast and has an elevationa1 range from 10 to 584 m. The
vcgetation is primari1y dense cleciclous forest, covering the slopes and
semicleciduous vegetation along the larger arroyos. The forests at Chamela
are notable for the diversity and abnndance of epiphytes and of vines.
Rainfall is primarily betwecn July ancl October, with practically non e
hctwcen February and 1\fay. The general sctting, vegetation aml climate
of the Estación are cliscused in some detail by Bnllock (1986; 1987; ancl
in this volume).
CLASSIFICATIO:'Ii A:\D CHECKLIST
The classification follows that uscd by Doyen, ct al. (1989) and Doycn
(1989). This arrangement excludes Zophcridae from Tenebrionidae and
includes Lagriidae and Allcculidac as suhfamilics (Doycn, 1972; Doyen
and Lawrence, 1979; Doyen ancl Tschinkel, 1982; \Vatt, 1971). Other deYiations from previous classifications are notecl wherc appropriate in the
following tcxt. One o[ the prim~try rcasom for compiling a fauna! list,
particularly for a local area, is to cnable identifications so that ecological
work may proceed. vVith this in mind thc list presentecl here i-; accompanied by illustrations intended to represent the general body form of
the commonly encountered genera, and hy a kcy to the genera and species, with yery brief diagnoses to the latter. Dates and localities are

presented for essentially all material examined, since most species haYe
been collected on1y a few times. Holotypes of newly described spccies are
held on loan at the California Academy of Sciences. Paratypes are deposited
in the Essig Museum of Entomology ancl in the collection of the Universidad Nacional Autónoma de México, D. F. and a reprcsentative collection
containing most of the known specics is deposited at the Estación de
Biología Chamela. The remainder of the material is housed in thc Essig
.l'VIuseum of Entomology, University of California, Berkeley.
The following tabulation is based on more than 1000 specimens. About
one-third of these were collected during a two week period in late July and
carly August, 1984. The remaining specimens rcpresent nearly CYery
month, but the great majority were collected during the period from July
to Dccember (e.gr., during the rainy season or shortly thereaftcr). This
distribution reflects both uneven seasonal distribution (most specic> are
active during the wet period) and unequal collecting activity. Thc only
concerted field effort made in December resulted in the only collections
of Trichiasida lutulenta and in largc collections of Eusattus mexicanus,
which previously had hardly been recorded from coastal Jalisco. At thc
present level of systematic knowledge of the Mesoamerican fauna it
is not possible to reliably determine all specimens of Tenebrionidae to
species. The type spccimens are scattered in many collections, and, evcn
if these could all be examined, for severa] large genera that havc never
bcen revised determination would still be very difficult without lcngthy
study. Genera which present special problems of this sort include BlajJstinus, Platydema, Strongylium, Statim and all Alleculini except Lobopoda. For these taxa specimens which do not clearly represent a described
cntity are listed as incertae sedis at the end of the list. Question marks
following a species name indicate that comparisons have not bcen madc
with the type specimens, or that the specimens from the Estación differ
slightly from those representing the type. References to papers publishcd
since the Blackwelder checklist (19,15) are listed under references cited.
Older papers are citcd fully in Blackwelder.

Phobelius mexicanus is similar to P. nevermanni Kulzer (1961) (Costa
Rica) and regularis Fairmaire (Brasil). In nevermanni the anterior pronotal corners are rounded and the elytra are tan. In mexicanus the anterior
pronotal corners are angulate and the elytra are dark brown, only slightly
paler than the prothorax. The lateral pronotal margins of nevermanni
are more distinctly angulate and the disk more finely punctate than in
mexicanus. In regularis the anterior pronotal corners are acute and laterally exserted. Other species of Phobelius are differentiated from mexicanus
by having tubercles on the e1ytral interstriae, at 1east on the declivity.

Triphalopsoides resemb1es Triphalopsis B1aisdell, which occurs on the
península of Baja California. The raised anterior margin of the elytra may
he a synapomorphy for these two genera, which also share a similar antennal
configuration and dorsal vestiture. In Triplzalopsis the medial epistomal
lobe is much more prominent with the apex angulate (acute or about
90°) and lateral margins crenulate (apex rounded, lateral hordcrs simple
in TTiphalopsvidrs). The eyes are slightly more prominent than the lateral
epistomal lohes, barely emarginate anteriorly and supertended by a fine
carina (less prominent than epistomal lobe, deeply emarginate and lacking
carina in Triplzalopsoides). The pronotum has the lateral borders narrowly margined (unmargined in Triphalopsoides). The intercoxal process ha~
the apex angulate (truncate in Triphalopsoidcs) ancl the tarsal claws are
about twice as long as in TTijJhalopsoides.
TriphalojJsoúles is similar to Somias Champion in general bocly configuration, but Sornias does not have the elytral base margined, has prominent co1wex eyes, and has obtuse anterior pronotal angles which are
not at al! prominent. However, it may be pointed out here that the clistinction between Triorophini and Trimytini (sensu Casey) is based mainl;:
upon thc relative breath of the mentum (Casey, 1907:~78), which i-,
intermediare in genera such as Trimytis LeConte and Tlascalinus Casey .
It is beyond the scope of this paper to investigate the relationship of these
two tribes, ancl TriphalojJwidcs is comiderecl to belong to Triorophini.

TTichiasida lutulenta is similar in size and shape to T. acerba (Horn)
and T. hispidula (LeConte). It is distinguished by its carinate pseudepipleural ridge (broadly rounded in aceTba, very weakly costate in hispidula); by its hroadly upturned pronotal margins (much more narrowly
upturned in hipidula, barely upturned in acerba); by its punctatc abdominal sternites (finely, sparsely papillate in acerba, more densely so in
hispidula); by having its apical metatarsomere equal to the basal (longer
in aceTba and hispidula); by having the tarsal claws no longer than the
third tarsal segment (distinctly longer in acerba and hispidula); and by the
deeply notched apex of the tenth antennal segment (moderately emarginate in acerba and hispidula.
As with many other Asidini, T. lutulenta adults are active during
daylight hours. Most Asidini have very restricted seasonal activity. Trichiasida acerba, hispidula and hirsuta (LeConte) are all active during
winter and early spring. T. lutulenta has been found only in December,
suggesting activity centered in the dry season at Charnela.

Typhlusechus ignotus is most similar to T. sjJilmani Aalbu and Andrews
(198:'J). It differs in the much more deeply excavate elytral base \Úth
prominent anterior facing tubercles opposing the prominences on the
posterior pronotal margin. In T. spilmani the elytral base is shallowly
excantc with a narrow emargination just above the epipleural ridge.
In T. ignotus the pronotal disk is barely depressed between the tuberculiform posterior prominences, which are sharply declivous laterally but barely defined medially. In T. spilmani the posterior prominences are gradually elevated laterally, but sharply dcclivous medially forming short,
longitudinal riclges (Aalbu and Andrews, 1985, Figs. 5, 8). Finally, in
ignotus thc anterior pronotal angles are broadly ancl evenly roumled,
whereas in spilmani they are angulate with on1y the apices rounded.
The scant biological information concerning Typhlusechus was summariLed by Aalbu and Andrews (1985). Nearly all available collection
records suggest an endogean or cavernicolous style of life, as do the morphological characteristics of the beetles. Thc species described here was
collected from leaf litter on north east facing slopes lcss than 500 m from
the heaclquartcrs facilities of the Estación. During the clry season the
heerle> probably retrcat into fissures ancl crevices in thc >oil.

Blapc1tinus cylindriformis is similar to grandis Champion and fortis
LeConte, but is flightlcss, with the mesosternum less than half the length

eyes are separated by a distance about six times the diameter of one
eye, and the lateral pronotal margins are evenly arcuate to the base. In
grandis and fortis the apical antennomere is ovoid, about one and one

Helops scintillatus is similar in shape and size to Nautes nitidissimus
Champion. In scintillatus the head and prothorax are much more coarsely
punctured. The prosternal process is briefly produced beyond the procoxae and declivous; the mesosternum is scarcely excavate and without
the lateral margins raised. In nitidissimus the prosternal process is strongly produced and the mesosternal fossa deeply excavate with strong margins. In scintillatus the elytral intervals are convex; in nitidissimus they
are flat. Helops suavis Champion has the general body form of N. scintillatus, but is much more finely punctate, has the elytral interstriae almost
flat (convex in scintillatus), the hypomeron strigose or smooth (coarsely
punctate in scintillatus) and the abdominal sternites very shallowly ancl
finely punctate (more coarsely, cleeply punctate in scintillatus).
Thc indications given by Champion (1887:276) are inadequate for
defining genera of new world Helopini. The species described here are
placed in Helops because of their combination of: lack of metathoracic
wings; more or less declivous prosternal process; non-excavate mesosternum; epipleura terminating well before elytral apex. However, all of
these characteristics also occur in sorne species which are presently included in Nautes (e.g., N. nitidissimus).

Allecula brachyptera differs from all other described members of the
genm in being flightless, with the metasternum shorter than the mesocoxa.
It is ~imilar in general appearance to Narses subalatus Champion, to
which it will run in his (1888) key. However, A. brachyptera has the pronotum widest much before the middle (widest at middle in Narses) and
has much finer strial punctures and coarser interstrial punctures. Comparati.-e studies will probably show that Narses has been derived from
Allccula or Alethia by loss of the hind wings. However, the numerous
differences between N. subalatus andA. brachyptera do not suggest a common ancestor.

Mophis marginicollis Champion and Sitophagus cyanoides (Champion)
(originally described in Mophis) are similar to uniformis in lacking sexual
dimorphism of the head. In both of these species the pronotal base is
distinctly bisinuate (almost straight in uniformis) and the punctation of
the head and pronotal disk is much coarser than that of the elytral interstriae (subequal in uniformis). In all other described Sitophagus the epistomum of males is modified, usually as dosally produced projections, but
as a deep medial emargination in alveolatus Doyen. In uniformis there is
no sexual dimorphism of head structures, but the posterior femur of males
bears a small tubercle on the posterior (inner) margin near the middle.
The aedeagus of uniformis is similar to that of hololeptoides. The specimen from the Estación was attracted to lights; the series from Oaxaca
·was found beneath bark of a dead tree.

Otocerus chamelensis is &imilar to dilaticornis Champion and torolae
Champion in Iacking lateral pronotal carinae, but is much smaller (11 to
13 mm versus 16 to 17 mm). In dilaticornis the elytral margins and epipleura are red, whereas chamclensis is unicolorous. In torolae the lateral
pronotal margin bears a small, ;harp tooth near the middle, while in chamelensis thc pronotal margin bears a weak umbo at most. In size and
ovcrall appearance chamelcnsis resembles nicaraguensis Champion, which,
howcver, has distinct lateral pronotal carinae.
At present Otoccrus is distinguished from Strongylium by having the
third antennal scgment shorter (versus equal to or longer than) the
fourtlt segment. This character clearly separates O. c!zamefensis from S.
c111inens 1\Iakiin, which otrm·s in thc arca arouncled Charnela and is similar
in general appearance. Howevcr, as pointed out by Doycn (l ~JS~l) Otocerus
likcly repre-;enh a specialüed subgroup of Strongylium which may not
warrant cladi-;tic recognition. It is also pmsible that thc shortening o[ the

kcy '\ h ich treats a local fauna mmt be used 11·ith special caution, since
additional, previously unrecorded taxa are very Iikely. This is particularly uue of a poorly known region such as the ~outhwestern coast of 1\Iexico. In this regard it may be remarked that the Chamelan fauna includes
a high proportion of taxa previously known from much further south.
sometimes as distant as Costa Rica. Furthemore. many of the species are
uncommon, and in about a clozen cases known only from a single specimen.
Genera 11·ith which special rare ~hould he med are: Blapstinus, Platydnna, Tarpela, Strongylium Statira and all AI!eculini. These taxa are
al! diH:roified in tropical ~Iexico, have never been reYised, ancl aclditional
