Species of Wyattella View in CoL :

fungicola Mamaev, 1976 View in CoL . Palearctic.

japonica Jaschhof sp. nov., described below. Palearctic. sinica ( Yang, 1998) [ Thaumacecidomyia View in CoL ]. Oriental. ussuriensis Mamaev, 1966 View in CoL . Palearctic.

Two unnamed species from the Palearctic region.

Wyattella View in CoL is a small, well-defined genus with a distinctly eastern Palearctic / Oriental distribution. Wyattella japonica is newly described here with the reservation that it cannot be compared character-by-character with Mamaev’s (1966, 1976) and Yang’s (1998) species, whose original descriptions lack specificity. Especially problematic is the fact that the male genitalia of none of these species were adequately illustrated. Wyattella lobata Yukawa, 1968 View in CoL is here excluded from Wyattella View in CoL and newly combined with Johnsonomyia View in CoL (see there). Two unnamed Wyattella View in CoL are known to me from Japan.

Diagnosis. The genus Wyattella contains conspicuously large, black-brown species, with male body lengths of 6.0–7.0 mm. The venation of Wyattella , characterized by presence of a furcate M1+2 and (single-branched) M4, is the most generalized vein pattern in the subfamily Winnertziinae, including Diallactiini ( Jaschhof & Jaschhof 2013: fig. 20). Antennal sensory hairs with hooded alveoli are scattered, not arranged in whorls or lines, and palpi lack translucent sensilla; both these conditions are not met in other Diallactiini . Basitarsi have spines and claws are usually toothed (untoothed in W. fungicola ), which are character states seldom found in diallactiines other than Wyattella . Male genitalia are peculiar for the presence of a thick, densely microtrichose membrane, apparently a medial outgrowth of the gonocoxites, which covers much of the ejaculatory apodeme and tegmen. The apex of the slender, telescopic ovipositor bears a number of characteristic large, sawtooth-shaped spines dorsally.
