Amiota (Amiota) macai sp. nov.

(figure 8)

Diagnosis. Surstylus with palm-like lobe bearing about three aristate processes on mesal surface (figure 8B); paramere and aedeagus slightly dilated apically; paramere with about three sensilla submedially (figure 8D, E).

Description. Male: Ocellar triangle dark brown. Frons brown to dark brown. ace brown. G ena brown.

Wing with 18–20 minute, peg-like spinules on ventral surface of costal vein between R and R.

2+3 4 +5

Legs: Mid tarsus with a row of minute cuneiform setulae on posteroventral surfa ce.

M ale terminalia: Epandrium constricted more than one-half width mid-dorsally, with about 17 setae near posterior to ventral margins (figure 8A). Surstylus nearly entirely pubescent, with fi nger-like process at posteroventral corner, about ten long prensisetae on distal margin, and a few stout, spine-like setae on inner surface figure 8B). Tenth sternite deeply constricted mid-dorsally, with a pair of setae laterally; lateral lobe-like process spherical (figure 8B). Anterior portion of hypandrium slightly broadened at middle (figure 8C). Paramere articulated basally with aedeagus (figure 8D, E). Aedeagus separated into a pair of slender processes as long as paramere and strongly curved ventrad (figure 8D, E); outer membrane erect basally (figure 8E). Ejaculatory apodeme: apical plate with fi ve pits per side (figure 8F); stalk thick, long (figure 8F).

Hol ot ype:, China: Shennongjia , Hubei, 26 July 1992, 1520 m, M. J. Toda leg. (D BSC ).

Par at ypes: 15, same data as the holotype except 26–27 July 1992 ( EHU and D BSC) .

Distribution. China (H ubei).

Relationship. This species closely resembles A. aristata in many characters of male terminalia, but can be clearly distinguished from it by the diagnostic characters.

Etymology. Patronym, in honour of Dr J. Máca of Czech Agency for Nature Conservation.
