Cyamops fumipennis L. PAPP View in CoL , sp. n.

( Figs 94–99 View Figs 94–99 , 136 View Figs 136–139 )

Holotype male ( HNHM): THAILAND: Trang Prov., Khao Chong Botanic Garden , rainforest, Nov 22, 2004, No. 43, leg. L. PAPP & M. FÖLDVÁRI.

Paratypes: 6 males (one of them with abdomen and genitalia in a plastic microvial with glycerol) and 9 females: data same as for holotype ; 1 male: ibid., forest brook, yellow pans, Nov 18–22, No. 40, leg. M. FÖLDVÁRI ; 1 female: Doi Inthanon N. P., below Haui Sai Nueng Falls , along the brook, Oct 30, 2004, No. 7, leg. L. PAPP & M. FÖLDVÁRI.

Measurements in mm: body length 2.02 (holotype), 1.96–2.15 (paratype males), 2.46–2.65 (paratype females), wing length 2.11, 2.00–2.17, 2.38–2.66 (paratypes), wing breadth 0.73, 0.72–0.75, 0.85–0.88.

Ocellar triangle and vertex shiny black, depressed region deep velvety black, orbits from middle of frons down to below antennal bases, silvery. Occiput together with most posterior part of genae deep dark graphite. Facial ridge silvery basally and brown from ocular isthmus down to mouth edge. Face, cheeks and genae otherwise yellow. Clypeus thin, hairpin-like. 7 peristomials, pseudovibrissae 0.11 mm, dorsally directed and divergent. Facettes of eyes below antennae much larger than those beside orbitalia. Inner fronto-orbital seta reclinate (0.14 mm) and slightly divergent, anterior fronto-orbitals strongly proclinate (0.24 mm) and slightly convergent. Vertical seta 0.22 mm long. Antennae yellow. Arista bearing 9 dorsal rays, basal 5–6(7) rays forked, 2(3) ventral rays behindg apical fork.

Thorax and abdomen dark greyish brown, shiny with thin grey microtomentum. Anepisternum silvery shiny. Katepisternum with thicker silvery microtomentum. 2 np, 1 prealar sa, 1 pa, as usual. Anterior dc seta 0.12 mm, posterior one 0.225–0.23 mm, i.e. less than double length of anterior one. Apical scutellars 0.24–0.26 mm long. Basal scutellars missing in most males, mostly present but weak in females: if present, they are hair-like and not longer than 1/6 (in females 1/4) length of the lateral scutellars. Two rows of short acmi, 1–1 pairs of rows of dc and ia microchaetae. Katepisternal seta medium-lomg, some additional thin katepisternals.

Basal 3/4 of femora dark (blackish brown), incl. knees; femoral bases, tibiae and most of tarsi yellow. Apical 2 tarsomeres of all legs black. Ventroapical seta of mid tibia very long. 0.225–0.23 mm, and thick.

Wing ( Fig. 136 View Figs 136–139 ) evenly fumose (blackish), wing base clearer. Costal ratios (paratype males): 68: 35.5: 10, 69: 33.5: 11.5, intra-crossvein sections and distal section of M: 28: 25.5: 61.5, 28: 22: 63.5. Halteres wax yellow, base of stalk grey.

Abdomen dark brown, basal two segments yellowish brown. Epandrium yellow, forms slightly more than 1/4 of a globe. Male tergite 6 almost twice longer than tergite 7 (bare), with some marginal and discal setae. Tergite 6 and 7 of about the same width. Also S5 strongly asymmetrical but not divided. The S6-S7 complex with a long broad, apically rounded medial process ( Fig. 94 View Figs 94–99 ). Left surstylus sickle-shaped in profile, dentiform in broadest view ( Fig. 95 View Figs 94–99 ). Right surstylus complex ( Figs 98–99 View Figs 94–99 ) with a dorsally directed basal (inner) process (perpendicular to the plane of figure), a broad rounded medial process and broad “body”. Aedeagal apodeme straight and rather broad, ejaculatory apodeme ( Figs 96–97 View Figs 94–99 ) long and not broad. Aedeagus similarly as long as aedeagal apodeme with concave conical apex.

view. Scale: 0.1 mm for all

In the key for Australasian/Oceanian species ( BAPTISTA & MATHIS 2000) it runs to C. delta KHOO (but not closely related). In the Oriental region, its closest relative is probably C. kaplanae . However, its wings are evenly fumose (on immature specimens all the longitudinal veins bordered by broad dark fascia). The male genitalia ( Figs 95–99 View Figs 94–99 ) are obviously different.

Stenomicra angentata SABROSKY, 1965 – 2 m 3 f: PF04/14; 1 m: PF04/29; 1 m: PF04/42. The species was described on the basis of a single female from Malaysia, but recorded also from India , Orissa ( PAPP 1974). Our specimens are surely conspecific, based first of all on the silvery spot of on the thoracic pleura. A species new for the fauna of Thailand.

Stenomicra angustiforceps SABROSKY, 1965 View in CoL – 1 m: PF04/14; 1 m: Trang Prov., Thung Khai Botanic G., pasture, 19. 11. 2004, A: Orosz; 4 f: FSz03/11. The species was described from Nepal and reported from India , Orissa ( PAPP 1974). Also this species is new for the fauna of Thailand (in the HNHM specimens also from Taiwan).

Podocera fascipennis MALLOCH, 1927 ( Figs 112–114 View Figs 107–114 ) – 4 m 5 f: FSz03/1; 2 m 6 f: FSz03/11; 1 m 7 f: PF04/28; 3 m 3 f: PF04/29; 1 f: PF04/30; 2 f: PF04/35; 1 f: PF04/36; 1 m 2 f: PF04/37; 3 m 8 f: PF04/38; 3 f: PF04/39; 2 m: PF04/42; 2 f: PF04/43; 1 f: Trang Prov., Thung Khai Botanic G., pasture, 19. 11. 2004, A: Orosz ; 2 f: OSz03/03; 2 f: OSz03/06; 1 f: OSz03/14; 1 f: OSz03/45. A species new for the fauna of Thailand. With its 16 m 47 f in our material this seems to be the commonest species of the family in Thailand. In the HNHM there are named specimens of this species also from Vietnam and Taiwan. We must stress that presently we have the concept of widely distributed species also in Stenomicridae .

Its surstylus bifid apically ( Fig. 112 View Figs 107–114 ) but different from that of P. claripennis sp. n. (below). Left long process of gonopod strongly upcurving, dorsally directed (short in dorsal view), in contrast to P. claripennis . Ejaculatory apodeme ( Figs 113–114 View Figs 107–114 ) similarly large as in P. claripennis but proximal part more rounded in dorsal view, distal (ductus) part much broadened in lateral view.
