Crockeria
gen. nov.
Type
species:
Crockeria kinabalu
sp. nov.
Etymology:
The genus is named after William Maunder Crocker (
1843-1899
), who was an administrator in Borneo.
Diagnosis:
Males of
Crockeria
gen. nov.
can be distinguished from males of other Stephanopinae by the following combination of characters: presences of a stalked MA with a concave apex, presence of a sclerotized filiform C, and a broad-based filiform E. Females can be distinguished by the C-shaped CO, short CD and round S.
Remarks:
Crockeria
gen. nov.
is most closely related to and likely to be confused with
Cebrenninus
,
Epidius
Thorell, 1877
,
Ibana
Benjamin, 2014
and
Pharta
Thorell, 1891
, known from the Oriental region. It can be separated from these genera, in addition to the characters given above, as follows: from
Cebrenninus
by the longer copulatory ducts and lack of ETP; from
Epidius
by the absence of an elongated male palpal tibia (tibia is longer than the cymbium in
Epidius
); from
Pharta
by the absence of a macro-trichobothrium on the palpal tibia, the absence of serrated tarsal setae, the absences of posterior epigynal pockets and by oval, dual-chambered spermatheca; from
Ibana
by the combined presences of a MA, C and E.
Description:
See description of the
type
species below.

and
Crockeria laevis
(

)
comb. nov.
Distribution:
Sumatra
(Mt
