Name
Limnobaris tibialis (Voss, 1953) comb. n. – Wikispecies link – Pensoft Profile
- Pertorcus tibialis Voss, 1953: 75. Holotype male, Kuatun [Guadun], Fujian, China (AKMB).
- Pertorcus tibialis pilifer Voss, 1958: 76. Holotype male, Kuatun [Guadun], Fujian, China (AKMB). syn. n.
Diagnosis
Limnobaris tibialis is a small species (2.1–3.1 mm) with sparse ventrolateral vestiture and erect setae on the elytron. Males have a sharply pointed, anteriorly directed process on the ventral edge of the protibia, which is located more basally than the blunt tooth of other species (Fig. 5). Limnobaris albosparsa, the only other species with a sharply pointed process, has a slightly wider penis basally, appressed rather than erect setae on the elytron and is allopatric. The number and width of white setae on the elytral interstriae vary considerably even in series taken at the same locality. Females may be confused with sympatrically occurring Limnobaris basalis, but the latter species has white setae crowded at the elytral base and is slightly less elongate. Most female Limnobaris tibialis can be distinguished by more basally inserted antennae.
Notes
Voss (1958)[1] distinguished a pilose “form” with slightly different protibial process. Even though the size of setae can differ noticeably between individual specimens, transitional forms occur even in the same series. Pertocus tibialis pilifer is a new junior synonym of the nominal species.
Distribution
The species is known from Southeast China (Anhui, Fujian, Guizhou, Jiangxi, Zhejiang) (Fig. 13).
Biology
In Northern Fujian, we found this species on several, ca. 20–30 cm tall Carex species. The larva develops in the basal, ca. 2 mm wide section of the culm. Pupation starts in July and newly eclosed adults appear in the same month.
