Cryphocricos latus
Usinger 1947
: Ann. Entomol. Soc. Amer. 40:340–341.
Type
repository:
Snow Entomological Museum Collection
(
Lawrence

USA
)
.
Type
locality:
Costa Rica
:
San Isidro del General
,
2,000 ft.
Discussion:
The
holotype
is a brachypterous male (
Fig. 19
) and
allotype
a brachypterous female. Seven brachypterous
paratypes
also are housed in the Snow Museum. The macropterous male and female were described by
Herrera
& González (2013)
.
Cryphocricos latus
is associated with fast current, large rocks, and coarse pebbles (
Stout 1981
). These tropical streams are subject to severe seasonal spates, which result in a high rate of downstream displacement of
C. latus
followed by a slow recolonization rate (
Stout 1981
). Because the macropterous form is uncommon except in the dry season, its ability to recolonize upstream following a spate is temporally limited (
Stout 1982
).
Diagnosis:
This species is similar to
C. obscuratus
in “all characters” but differs from it by a wider body/length ratio, length>
7 mm
, and claval commissure subequal to the length of the scutellum (
Usinger 1947
). Specimens that I have examined from
Costa Rica
and
Panama
readily conform to characteristics of both species; thus, I suspect that
C. latus
and
C. obscuratus
are conspecific. Moreover, specimens of
Cryphocricos
from
Guatemala
and
Belize
also are small, and those from
Belize
had body width/length ratios suggesting a
C. latus
identity, but body lengths spanned those of three species (
C. hungerfordi
,
C. latus
,
and
C. obscuratus
) (
Sites
et al.
2018
); thus, considerations of conspecificity must also include
C. hungerfordi
.
