Clydonium zamoranensis Khalaim , sp. nov.

( Figs 45–49 )

Material examined. Holotype female ( FSCA), Honduras, Francisco Morazán Prov., Monte Uyuca, near El Zamorano , 1900 m, cloud forest, Malaise trap, 10–20.viii.1992, coll. C. Porter & L. Stange.

Paratypes. HONDURAS. 2 ♀ ( FSCA, ZISP) same location and collectors as holotype, but 1800 m, 25.vii.1992 . 1 ♀ ( FSCA) Francisco Morazán Prov., San Antonio de Oriente, Cerro Uyuca , cloud forest, Malaise trap, 7–13.v.1990, coll. R. Cave.

Description. Female. Mandible stout, with upper tooth somewhat longer and broader than lower tooth. Malar space about 0.2× as long as basal mandibular width. Head polished, finely and very sparsely punctate. Face 1.35× as wide as long ( Fig. 46 ). Head in dorsal view with genae distinctly and roundly constricted behind eyes. Posterior ocellus separated from eye by about 1.8× its own maximum diameter.

Mesosoma polished, almost entirely finely and very sparsely punctate; lower part of pronotum, mesoscutum, speculum and dorsal part of propodeum almost impunctate. Pronotum in profile long, mediodorsally with anterior margin reflexed backwards. Epomia short but distinct. Notaulus weakly impressed. Epicnemial carina completely absent. Epicnemium without secondary carina. Submetapleural carina completely absent ( Fig. 47 ). Propodeum in profile evenly rounded. Pleural carina absent but its path indicated by thin and sharp groove.

Fore wing length 9.5 mm. Hind wing with first abscissa of nervellus straight, vertical, twice as long as second abscissa ( Fig. 47 ).

First tergite almost 1.2× as long as posteriorly broad, polished, without lateromedian carinae, with dorsolateral carinae present before spiracles (althought usually not reaching spiracles) and completely absent posterior to spiracles ( Fig. 48 ). Second tergite mediodorsally without median indentation, on anterior margin with a pair of sublateral impressions ( Fig. 48 ). Second tergite transverse, smooth, with a pair of median swellings medially, with fine scattered punctures posteriorly and laterally, with oblique lateral grooves ( Fig. 48 ). Tergites 3–5 similar but with distinct punctures on anterior margins. Ovipositor almost 2.5× as long as hind tibia (projecting beyond apex of metasoma by about 1.7× length of hind tibia), nearly straight or very weakly decurved ( Fig. 45 ), very strongly compressed laterally, apex of lower valve with a scabrous area just proximal to teeth ( Fig. 49 , arrow).

Head and antenna black; clypeus yellowish orange to orange-brown. Mesosoma predominantly brownish black to black; mesoscutum orange-brown; scutellum orange-brown in anterior 0.7 and yellow in posterior 0.3; postscutellum yellow; mesopleuron extensively marked with orange-brown in lower part and posteriorly to almost entirely orange-brown; metapleuron sometimes partly orange-brown. Legs predominantly yellowish orange, fore (sometimes also mid) coxae and trochanters white ( Fig. 45 ). Metasoma predominantly black; second and following tergites with triangular white marks posterolaterally ( Fig. 45 ); tergites 2 and 3 (sometimes also tergite 4) with transverse median mark near posterior margin ( Fig. 48 ); ovipositor sheath black. Wings infumate with yellowbrown, pterostigma pale yellowish brown ( Fig. 45 ).

Male. Unknown.

Etymology. The new species is named after the type locality, [El] Zamorano.

Distribution. Honduras.

Comparison. The new species is similar to the Costa Rican and Panamian species C. analuisae Gauld as both have almost entirely black head (except clypeus), completely lacking epicnemial and submetapleural carinae, and predominantly black metasoma with white lateral and posteromedian marks. Clydonium zamoranensis sp. nov. differs from C. analuisae by having distinct epomia (absent in C. analuisae ), entirely orange-brown mesoscutum and partly orange-brown mesopleuron ( Fig. 47 ) (in C. analuisae mesosoma is entirely black), and pale yellowish brown pterostigma ( Fig. 45 ) (black in C. analuisae ). It should be noted that all specimens of C. zamoranensis sp. nov. were taken at 1800–1900 m as well as C. analuisae which was collected between 1600 and 2600 m, while most other Central American species of Clydonium occur in lowlands below 1000 m.

In the key to the Costa Rican species of Clydonium ( Gauld et al. 1998: 28) , the new species runs to couplet 6 but does not correspond in this couplet neither with C. madrigali Gauld nor C. quirosi Gauld as it lacks epicnemial carina, lacks secondary carina of the epicnemium and lacks lateromedian carina on tergite 1. The new species also differs well from the both by its colour pattern; e.g., C. madrigali possesses all legs and pterostigma black and metasoma reddish brown, C. quirosi possesses facial orbits white, legs predominantly black, pterostigma black and metasoma orange-brown, while in C. zamoranensis sp. nov. the head is black, all legs yellowish orange and metasoma black with white markings.
