Poanes melane (W. H. Edwards, 1869) (BCS segregate)
('Baja' Umber Skipper)

Pinned Specimens photo collection:


 

Distribution and Larval Foodplants:

MEXICO: Baja California Sur, higher elevations of the southmost Cape Region
 

Diagnosis

     Differs from other P. melane populations in being darker, almost without ochre overscaling above and with reduced macules in the discal band. Recorded only from the higher elevations of the southmost Cape Region, Baja California Sur, Mexico.

     According to the literature (see below), only 4 specimens are known with the following data:

                         Baja California Sur: La Laguna, 2♂, 14-x-41 (E. Ross and Bohart, CAS), 2♂, 28-viii/1-ix-77 (R. Snelling, LACM).

     Any additional information about this skipper will be very much appreciated.

       Locality:  20 mi. east Descanso, Apr. 28, 1954.
       On the basis of two specimens seen, it appears that the Poanes melane reported by
RINDGE from  the Sierra Laguna  in the Cape district represents  a distinct population and
possibly will be better  treated as another subspecies when more specimens are available
for study.

Paratrytone melane  subsp. 
 
Poanes  melane,  RINDGE,  1948,  Proc. Cal. Acad. Sci.,  fourth ser.,  vol. 24, 
    p. 309; POWELL, 1958,  Lepid. News,  vol. 12, p. 32. 
 
    The  available  sample  of  the  populations inhabiting the Sierra dela Vic- 
toria  of  the Cape  Region  is comprised  of only two  specimens. Nevertheless, 
these  two males  are sufficiently  distinctive in appearance  to make me almost 
certain that the populations they represent constitute a very distinct geograph- 
ical  segregate.  Powell (1958, p. 32) offered a similar opinion. 
    Males of  the California  population invariably  have present  on the  upper 
wing  surface  considerable  ochre  overscaling  on the  forewing  except  for a 
large  dark patch  proximal  to the discal spots and posterior to the cell. This 
dark  patch is basally  demarked  by a particularly rich overscaling on the bas- 
al third  of the wing.  The overscaling  imparts  an impression  of a very dark, 
yet  ochre colored  wing  bearing a large  black  or dark  brown  discal spot. 
    The  Cape Region  specimens  almost  totally  lack  this overscaling;  hence 
the  forewing  is uniformly  brown,  without  a conspicuous  black discal patch. 
The  discal ochre  spots are  very  reduced  in one  specimen  and almost absent 
in  the other.  The hindwings  are  as dark  as the forewings.  The macular band 
is  narrowed as  in the Mexican  subspecies but  not particularly shortened, and 
even  more vaguely  defined than  is the  case with the northern subspecies. The 
Cape  specimens differ  from  the Mexican  populations  in  having  even  darker 
forewings  with much  smaller spots,  and in  the very  vaguely defined spots of 
the hindwing. 
    On  the lower  surface  of  the wings  the  Cape  specimens  resemble  those 
of  the California  populations  but have  less of the reddish cast basally, and 
on  the hindwings  the spots  are sharply  defined  outwardly, as in Mexican ex- 
amples,  but they  scarcely  contrast  to the  ochre-brown  ground  color of the 
wing.  The abdominal  venter is  a rich ochre, neither  buff colored as in Mexi- 
can specimens,  nor pale  buff-ochre  as is the case in samples from California. 
    No additional  material was  examined.

PENINSULAR DISTRIBUTION:  Restricted  to the higher  elevations of the Sierra de
         la Laguna in the Cape Region.
FLIGHT PERIOD:   The   few  specimens  available  were  collected  in  late  August
         and  mid-October.
LARVAL HOSTS: Presumably grasses (Poaceae).
REMARKS:  Powell (1958) first recognized  that specimens of  P. melane from the
         mountains   of   the   Cape   Region   did   not   represent   typical   P.  melane.

         subspecies  and  this  undescribed  taxon.
