Type material.
Holotype ♂ - CHINA, Yunnan Province, Zhongdian County, northern Zhongdian [
27°50.119'N
,
99°42.426'E
, elevation 3285 m], July 23-30, 2000, X. Yu & H. Zhou (IZCAS). Paratypes: same data but Xiaoxueshanyakou [
27°49.119'N
,
99°41.426'E
, elevation 3265 m] - 1♂ (IZCAS); same data but Bitahaixi [
27°48.105'N
,
99°40.429'E
, elevation 3285 m] - 2♂ (IZCAS).
Etymology.
The specific name is taken from the Latin adjective
"alpinus"
, which means
"alpine"
and refers to the high altitude of the type locality.
Diagnosis.
The new species is similar to
Raveniola chayi
sp. n.,
Raveniola shangrila
and
Raveniola songi
, all also occurring in Yunnan, but differs by the slightly twisted and bent distal portion of the embolus (Figs 1
A-C
, 2
A-C
, cf. Figs 6
A-C
, 7
A-C
).
Raveniola alpina
sp. n. can be distinguished from the latter species also by the absence of PMS (present in
Raveniola songi
).
