Abstract
The second and final part of a revision of the European species of the genus Rhabdomastix Skuse, 1890 is presented. The subgenus Rhabdomastix s. str. is revised. Seven species are redescribed, Rhabdomastix (Rhabdomastix) japonica Alexander, 1924, R. (R.) laeta (Loew, 1873), R. (R.) borealis Alexander, 1924, R. (R.) edwardsi Tjeder, 1967, R. (R.) subparva Starý, 1971, R. (R.) hirticornis (Lackschewitz, 1940) and R. (R.) beckeri (Lackschewitz, 1935). Three new synonyms are proposed. Lectotypes of four pertinent nominal species are designated. Descriptions are provided of six species, viz. R. (R.) laetoidea sp. n. (Czech Republic, Slo- vakia, Bulgaria, Ukraine), R. (R.) crassa sp. n. (France, Czech Republic, Slovakia), R. (R.) corax sp. n. (Bulgaria, Greece), R. (R.) eugeni sp. n. (France, Switzerland, Germany, Czech Republic, Slovakia, Italy, Romania, Bulgaria, Greece, Ukraine, Armenia), R. (R.) filata sp. n. (Bulgaria, Greece, European Russia, Turkey, Georgia, Armenia) and R. (R.) georgica sp. n. (Georgia). Male and female terminalia are illustrated for all the species, and a key to species is appended.
Highlights
In the first part of this revision published recently (Starý, 2003), the taxonomic history of the genus Rhabdomastix Skuse, 1890 was reviewed, its classification outlined and re-assessed, and a new subgenus, Lurdia Starý, 2003, was established
It should be noted that the venational pattern in Rhabdomastix s. str., with its vertical R3, combined with the hexagonal discal cell and distinctly arched M1+2 and M3, is quite unique within the Limoniidae
R. (R.) laeta is very similar to pale specimens of R. (R.) japonica, differing in the structure of the antennae and the male and female terminalia
Summary
In the first part of this revision published recently (Starý, 2003), the taxonomic history of the genus Rhabdomastix Skuse, 1890 was reviewed, its classification outlined and re-assessed, and a new subgenus, Lurdia Starý, 2003, was established. Unless otherwise stated in the sections on Material examined, the material under study is dry-mounted and collected by netting. Small to medium-sized species (cf Figs 1–4). Antenna 16-segmented, of variable length, from very short (Fig. 7), about twice as long as head, to notably long (Fig. 11), longer than body. Flagellomeres short, oval, decreasing in size, especially in breadth, towards apex of short antenna, or considerably long, cylindrical or spindle-shaped, with terminal flagellomere of long antenna very small. Subequal in length to diameter of head, with terminal palpomere only a little longer than penultimate (Fig. 14), or longer, with terminal palpomere twice as long as penultimate one (Fig. 13). Male terminalia (cf Fig. 17 and other relevant figures): Segment 9 generally parallel-sided, simple, with at most small lobe dorsally at posterior margin on each side of median interruption (except in beckeri, Fig. 44). Spermathecae (Figs 46–56) two or three in number, spherical, oval, or reniform, subequal in size to each other, or, if three, one spermatheca sometimes tending to be smaller than other two
