CHINA: 3 ♂♂, Fujian, Kuatun (Guadun), 27°40′N, 117°40′E, 21 Mar. 1946, Tschung-Sen leg. (ERC); 4 ♂♂, same data but 28 Apr. 1946 (ERC); 1 ♂, same data but 24 Apr. 1946 (ERC); 1 ♂, same data but 29 Apr. 1946 (ERC).

Remarks

This species was described by Endrödi (1952) as Dasyvalgus jordansi Endrödi, 1952 . Having its parameres clearly of the same shape as in Hybovalgus (Fig. 8 I–J), we include this species in the latter genus (new combination).

The female is unknown.

Species variability

Hybovalgus jordansi shows little morphological variation, but varies in size (length 5.6–6.5 mm; width 3.3–3.9 mm). In some specimens the posterior half of the lateral margin of the pronotum narrows in a straight line from the middle to the posterior corner; in other specimens it narrows in the same way, but noticeably arched inwards. The latter is a morphological character used by Miyake (1985) as a main character in his key to Taiwanese Hybovalgus species, but it seems like an unstable character to separate the continental species of the genus.

Flight period

Adults of H. jordansi were collected from the end of March to the end of April.

Distribution

This species seems to be endemic to the northern mountains of Fujian (China).
