Description
Yunnaniata Lopatin, new genus
(Figs 21–27)
Body length 8.0 mm, width at humeral calli 3.0 mm, width at posterior third of elytra 5.0 mm. Body widely ovoid, strongly widening posteriorly. Flightless. Antennae short, wide (Fig. 21). Antennomere two slightly shorter than three or four (Fig. 21). Maxillary palpi slender, palpomeres two and three strongly widening distally, nearly triangular. Palpomere four small and narrow, narrowing distally. Antennal calli nearly triangular.
Pronotum (Fig. 22) weakly convex, with anterior corners protruding anteriorly. Pronotal sides straight and parallel-sided from base to middle, widening and rounded towards apex. Pronotal disk with light impressions on sides. Anterior margin with slight border. Lateral margins slightly swollen and separated by thin longitudinal impression visible only anteriorly.
Elytra with rounded humeri, anteriorly much wider than pronotum. Elytral punctures confused. Epipleura wide, narrowing across metacoxae, disappearing before apex.
Procoxal cavities open. Intercoxal prosternal process narrow, widening posteriorly. Mesosternum wide, strongly bordered, widely connected with metasternum (Fig. 23).
Legs thick, meso- and metatibiae with short, poorly visible spur. First metatarsomere as long as two following tarsomeres together. Ventral surface of tarsomeres covered with thick hairs, only third tarsomere has thin, bare groove. Claw with denticle.
Type species: Yunnaniata konstantinovi Lopatin, new species.
Comments: Yunnaniata is similar to Spitiella Laboissierre and Paraspitiella Chen and Jang, but can be separated from both genera by its thick and short antenna, with antennomeres two to seven of the same length. Yunnaniata also can be separated from Spitiella by the open procoxal cavities and small eyes, and from Paraspitiella by the absence of the hind wings, the shape of the pronotum, and wide elytra.
Etymology: The generic name refers to the type locality.
