Anaspis cooteri sp. n.

( Figs 3 , 14 , 26 , 31 )

Holotype ♂ ( NMGW) China: Beijing, Dongling Mts., Xialongmen , Mei Yao Yu, N 39ᵒ 96′, E115ᵒ 43′. 16.vi.2001. J. Cooter. / On flowers of Hydrangea bretschniederi Dipp . Paratypes 9♂, 6♀ ( NMGW, BMNH, ZMHB), same data as Holotype .

Diagnosis. General diagnosis of holotype (male): Length (fore margin of pronotum to apex of elytra in mid line) 2.7 mm. Head, except for distal margin of fronto-clypeus, pronotum, scutellum, elytra and underside black; distal margin of fronto-clypeus and labrum yellow brown, labrum darker at centre; maxillary palpi, basal four segments of antennae, fore tibia and tibial spurs of all legs yellow; apical six segments of antennae black; coxae, trochanters and femora of all legs, and tibia of mid and hind legs brown; tarsi brown, first and second segments of mid and hind legs paler in basal half. Entire body densely covered with short grey pubescence.

Head. Antennae: first antennomere almost rectangular, about 1.5× as long as wide; second antennomere cylindrical about as long as first; third antennomere cylindrical, slightly widened at apex, as long as second; fourth antennomere like third, but slightly longer; fifth to tenth antennomeres slightly shorter than fourth becoming progressively broader; eleventh antennomere ovate, slightly longer than tenth. Apical segment of maxillary palp securiform. Pronotum: 1.2× as wide at base as long in mid line; hind angles obtuse, rounded; lateral edge straight when viewed from side. Scutellum: not visible in holotype. Elytra: 2.9× as long as pronotum. Abdomen: Ventrites 1–4 convex, but not keeled; 3 with a pair of small, thin, very slightly curved appendages, joined at the base; 4 with a pair of much shorter slightly curved appendages; overlapped by those of segment 3; 5 with a narrow V shaped notch at centre.

Legs: Fore leg ( Fig. 3 ) with femora moderately flattened anterior-posterior, and slightly excavated on the posterior surface, the ventral edge concavely excavate; tibia about same length as femora, slightly flattened anteriorposterior, almost parallel sided for most of its length, but abruptly narrowing at basal sixth, with a dense distal fringe of yellow spines and two yellow spurs slightly longer than tarsal segment 1; tarsal segment 1 flattened, cylindrical, about twice as long as wide; 2 about as long and as wide as 1, slightly widening distally; 3 slightly shorter than 2, approximately heart shaped with a deep medial excision distally, about as wide as long, with a long semicircular ventral pad extending distally beneath the entire length of segment 4; 4 very small, almost triangular, slightly longer than wide; 5 elongate, club shaped about as long as 3 and 4 together, claws small curved, slightly widened at base. Mid leg with femora strongly anterior-posterior flattened; tibia about as long as femora, regularly widening from base to apex, the ventral margin almost straight; with a dense distal fringe of yellow spines and a pair of long yellow spurs, the longer slightly less than half the length of tarsal segment 1, the shorter about one-third length of segment 1; tarsal segment 1 long, cylindrical, 0.48 length of tibia; 2 shorter, cylindrical, 0.56 length of 1; 3 shorter, 0.55 length of 2, approximately heart shaped with a deep medial excision, with a long semicircular ventral pad; 4 very small oblong, slightly longer than wide; 5 elongate, club shaped about as long as 3 and 4 together, claws small curved, slightly widened at base. Hind leg with femora strongly flattened anterior-posterior; tibia about half three quarters length of femora, strongly widened from base to apex, about 4.0× as long as wide at apex, with a dense distal fringe of short yellow spines and two yellow spurs, the longer about half the length and the shorter about onethird the length of tarsal segment 1; tarsal segment 1 moderately widening at apex, about four× as long as wide at apex, about 0.63 length of tibia; 2 slightly widening at apex, about 0.68 length of 1; 3 very slightly widening at apex, about 0.83 length of 2; 4 cylindrical, about 1.18× length of 3, claws small, slightly curved, slightly widened at base. Genitalia ( Fig. 14 ): Parameres not hooked at apex; basal piece 2.3× as long as parameres.

Variation: Length 2.7–3.0 mm; the only colour variation noticed is that the apical segment of the maxillary palp is partly black along the dorsal edge in some ♂ specimens. Pronotum: 1.2–1.3× as wide at base as long in mid line. Scutellum: Triangular about as wide as long. Elytra: 2.7–3.2× as long as pronotum.

General diagnosis of female: Length 2.7–3.2 mm. Colour as in ♂. Head: as in ♂. Pronotum: 1.3–1.4× as wide at base as long in mid line. Scutellum: as in male. Elytra: 3.0–3.3× as long as pronotum. Abdomen: as in male but without appendages and 5 th ventrite without a notch, broadly rounded at apex. Legs: Fore leg as in male but with the following differences: femora not flattened, not excavate on the posterior surface and with ventral edge not concavely excavate; tibia not obviously flattened anterior-posterior, not parallel sided and more gradually narrowing at basal sixth; tarsal segment 1 elongate cylindrical about three to four times as long as wide, 2 about two-thirds length of 1, slightly widening at apex; 3 about three-quarters length of 2, more parallel sided, less heart shaped than in male. Mid and hind legs as in male.

Comparative diagnosis. This species appears to be most closely related to A. nigripes differing in the smaller appendages of the ventrite 3 of the male (compare Figs 26 & 22 ); the more elongate pronotum, with the lateral margins almost parallel sided in front of hind angles (compare Figs 31 & 33 ).

Etymology. This species is named for Jonathan Cooter, the collector of the type series.
