Diagnosis. In general facies, the
holotype
of
P. wilkinsoni
(BMNH) looks most like
P. nigropenicillia
, however, it has a slightly greater forewing length. The identity of
P. wilkinsoni
is enigmatic because the
holotype
lacks the abdomen and the hindwings are in poor condition.
Redescription. Male forewing without tuft of erect scales near base of costa. Male hindwing without hairpencil in fold of vein CuP. Male genitalia unknown (abdomen missing). Female genitalia unknown.
Holotype
ɗ,
Chile
, Valparaiso,
Nov–Dec 1881
, T. Edmondo (BMNH).
Remarks. Based entirely on external features,
Brown (1989)
transferred this species provisionally to
Bonagota
, where it remained (
Powell et al. 1995
,
Razowski 1999c
,
Razowski and Becker 2000
); however,
Bonagota
,
Apotomops
, and
Ptychocroca
are extremely similar in facies. Because the hindwing of the single specimen (
holotype
) is slightly damaged, the presence of male secondary characters is not clear. It is possible that this species is conspecific with one of the species of
Ptychocroca
we describe above; however, we have no evidence of which one. Although
P. s i m p l e x
has the same
type
locality as
P. wilkinsoni
(Valparaiso,
Chile
), the former has a conspicuous tuft of erect scales on the costa of the forewing which is lacking in
P. w i l k i n s o n i
. Alternatively,
P. wilkinsoni
may belong in
Bonagota
. Because we have seen no specimens of the latter genus from
Chile
where
Ptychocroca
is widespread and abundant, we suspect that
P. wilkinsoni
is placed more appropriately in
Ptychocroca
.
