줄똥풍뎅이속은 호흰개미성인 줄똥풍뎅이족에서 가장 많은 종수를 보유하고 있다. 국내에는 광양줄똥풍뎅이 한 종만이 기록되었으나 또 다 른 종인 Rhyparus helophoroides Fairmaire, 1893를 새로이 발견하여 보고한다. 본 종의 진단형질과 그 사진, 한국산 줄똥풍뎅이속의 검색표의 제 시와 함께 생태에 대한 간략한 정보를 제공한다.
Rhyparini is one of the tribes of well-known termitophilous scarabs included in Aphodiinae Leach, 1815. Several species of the tribe are known to live in association with termites, with both organisms occurring together in relatively large numbers. In extant numbers of this tribe, the larvae live inside termite nests.
The tribe Rhyparini can be distinguished by the following combination of characters: clypeus usually bidentate though sometime feebly so, inflexed edge medially obtusely angulate; frons and vertex with tufts of setae or longitudinal tubercles; pronotum with six longitudinal costae equally spaced in at least posterior half of disc, lateral pronotal edge at least feebly bilobed in anterior half; elytra costae, costae varying on height, number and spacing, elytral apices frequently bulbous, epipleura narrow; posterior prosternal process hastate; antenna 9th segmented, club 3th segmented, segments of club short and compact.
The tribe includes 77 species of 12 genera worldwide, and Pittino (2006) published a key to world genera in the subfamily Rhyparinae (tribe Rhyparini).
In total, nine species of two genera in the tribe Rhyparini have been recorded in the Palaearctic region up to date: Rhyparus Westwood with eight species and Sybacodes Fairmaire one species, In Japan three species are known, China with one and Taiwan five. However, up to date, any has not been reported in Korea.
In the present study we report on the tribe Rhyparini from Korea for the first time, based on Rhyparus azumaiazumai Nakane, 1956. Diagnosis and illustrations of detailed diagnostic characters, including male genitalia are provided.
