Sparedrus malickyi sp. nov.

( Figs. 2 , 24, 26)

Type locality. Northern Thailand, Chiang Mai province, Doi Suthep.

Type material. HOLOTYPE: J, ‘ Thailand, Doi Suthep , 19.i.1990, Malicky lgt.’ ( NMPC).

Description. Coloration. Body entirely terra-cotta ( Fig. 2 ).

Male. Eyes large and protruding, head across eyes ca. one fourth wider than pronotum, very slightly narrowing posteriorly behind eyes. Frons between eyes very narrow, ca. twice as narrow as maximum width of antennomere 2. Last maxillary palpomere very narrowly securiform. Antenna very long, exceeding body by ca. length of elytra; antennomeres 3-10 more or less serrate with arcuate inner margin and with protruding inner lateroapical corner, antennomeres 6-11 more or less flattened dorsoventrally, more or less curved. Surface of vertex verrucose, matt, covered by sparse, long, semierect white pubescence forming a corner between eyes and paired asterisk in central part of vertex. Pronotum subcylindrical, with small flat area closely before posterior margin, its anterior margin very slightly rounded with very shallow emargination in its middle, lateral margins slightly converging posteriorly, straight, posterior corners obtuse, posterior margin rounded. Surface of pronotum verrucose, matt, with long, sparse, semierect white hairs forming two almost parallel and continuous mediolongitudinal lines and two posterolateral lines. Elytra almost parallel-sided, lateral margins very slightly sinuate in its middle portion, surface very densely and rather deeply punctate (Fig. 24), matt, covered by sparse, long, semierect white pubescence, elytral nervation slight but visible in subhumeral portion, slightly emphasized by pubescence. Last tergite by ca. one third exceeding last sternite, with slightly emarginate apex, apex of last sternite arcuately emarginate. Tegmen reaching ca. three fourth of length of aedeagus, aedagus as in Fig. 26 .

Female unknown.

Length (J). 8.0 mm.

Differential diagnosis. Sparedrus malickyi sp. nov. belongs to S. longicollis species group as defined by ŠVIHLA (2006b). It is related to S. tryznai taunnguensis Švihla, 2006 and S. chiangmaiensis sp. nov., differring from both by the well-developed elytral nervation, denser and deeper elytral punctation, and aedeagal teeth not protruding laterad (cf. Figs. 2-4 , 23-24, 26-28).

Etymology. This species is dedicated to its collector, Hans Malicky (Lunz am See, Austria), well-known specialist in Trichoptera.

Distribution. Northern Thailand.
