MONOGRAPHIC REVISION OF PLATYCOELIA 155
Callichloris nigricauda, Arrow 1899:369
[new combination, comment on morphology].
Pelidnota nigricauda (=Platycoelia
nigricauda, lapsus calami), Onore 1997:279,

TYPE SPECIMENS. Platycoelia parva
Kirsch lectotype male at SMTD labeled a)
“Ecuador 5032” (green label, handwritten), b)
“Typus!” (pink label, typeface), c) “Platycoelia
parva Kirsch” (handwritten), d) “PLATYCOE-
LIA PARVA KIRSCH M LECTOTYPE A.B.T.
SMITH 2002” (red label, handwritten and
typeface), e) “parva Kirsch 85” (green label,
handwritten). Lectotype here designated.
See Methods and Materials section for a
statement of taxonomic purpose. One female
paralectotype at SMTD labeled a) “Paramo
Bord oncillo 3300” (handwritten), b) “5034”
(green label, handwritten), c) “PLATYCOE-
LIA PARVA KIRSCH F PARALECTOTYPE
A.B.T.SMITH 2002” (yellow label, handwritten
and typeface). Kirsch (1885) did not state
how many specimens were in the original type
series, but Ohaus (1904b) speculated that
there were more than the two detailed above.
The existence and location of other paralectotypes
are unknown. Type locality: Ecuador.
Platycoelia nigricauda Bates lectotype
male at MNHN labeled a) “Cotopaxi 12000ft.”
(handwritten), b) “Platycoelia nigricauda

Det:A.B.T.Smith 2002” (typeface). Lectotype
here designated. See Methods and Materials
section for a statement of taxonomic purpose.

f) “Platycoelia parva Kirsch, 1885 F
Det:A.B.T.Smith 2002” (typeface). Bates
(1891b) had four specimens in his original
type series. The location of the one remaining
paralectotype is unknown. Bates (1891b) also
mentioned a fifth “immature” specimen from
Antisana. This specimen is excluded from the
type series because it is distinguished as a
“variety,” and the current location of this
specimen is unknown. The type specimens of
P. nigricauda did not have any unique character
states from the specimens of P. parva;
therefore I am synonymizing the two names.
The form of the mouthparts and size of these
specimens are somewhat variable, but I could
not find consistent patterns between populations.
Whether these differences are intraspecific
traits or interspecific character states
remains an unanswered question. More specimens
will have to be studied in order to determine
the precise limits of the species. Type
locality: Volcán Cotopaxi, Ecuador. NEW
SYNONYMY.
