Diagnosis.

This species is easily distinguished from congeners by the following combination of characters: Small shore flies, body length 1.15-1.80 mm. Head: Frons bi- or tricolored, lacking iridescent microtomentum, ocellar triangle largely and fronto-orbits whitish tan to tan, ocellar triangle with anteromedial, narrow, slightly oval darkened area, triangle broadly extended to anterior margin, parafrons grayish charcoal. Antenna largely yellow, only dorsum of basal flagellomere slightly darkened. Face narrowed at midheight, mostly unicolorous, whitish gray to blackish gray except for mediovertical brown vitta; parafacial creamy white. Gena relatively short, gena-to-eye ratio 0.08-0.09. Thorax: Mesonotum with 4 elongate, mostly separated spots (Fig. 69); presutural supra-alar seta well developed. Wing conspicuously patterned with distinct brown spots (Fig. 70); vein R2+3 distinctly angulate subapically, apices angled toward costa; at vertex of angle also bearing a stump vein, another stump vein near middle; costal vein ratio 0.76-0.87; M vein ratio 0.66-0.75. Femora brownish black; forefemur with 4-5 stout, peg-like setae on apical third along posteroventral margin; tibiae largely brownish black, apices yellow; tarsi yellow. Abdomen: Tergite 5 of male truncate posteriorly. Male terminalia (Figs 71-74): Epandrium in posterior (Fig. 71) view roundly U-shaped, bluntly oval, narrower dorsally and ventrally, slightly wider at midheight, lateral arm becoming wider ventrally, curved medially ventral margin ventromedial gap V-shaped, ventral angle bearing loosely clustered setulae; cercus hemispherical, pointed dorsomedially, more setulose dorsally, medial margin straight; gonite in lateral view (Fig. 74) robustly rod-like, shallowly curved toward aedeagal base, shaped like a banana, in ventral view shallowly curved with extension toward aedeagal base narrow, thumb-like, thereafter moderately wide, widest subapically; aedeagus in lateral view (Fig. 74) comparatively narrowly truncate basally, thereafter expanded, widest sub-basally, thereafter tapered to rounded apex, apex with short, recurved anterior point, in ventral view (Fig. 73) as an elongate, shallowly rounded, narrowed medially, basal margin somewhat truncate with shallow, medial emargination, apical margin tapered to angulate, rounded apex; phallapodeme in lateral view (Fig. 74) Y-shaped with one arm of Y a short, irregularly narrow keel, keel irregularly tapered, pointed apically; hypandrium in lateral view (Fig. 74) narrowed basally, apical ½ -2/3 wider, narrowly rectangular, rounded anteriorly, in ventral view as a very broad, short H with short arms, anterior emargination broadly V-shaped, posterior emargination very broadly and shallowly U-shaped.

Type material.

The holotype female of Ditrichophora painteri Cresson is labeled "Puerto Castilla B. F. Hond. 6-V-26 [6 May 1926] R. H. Painter, Co ["B. F." handwritten]/TYPE No. 6366 Ditrichophora PAINTERI E.T.Cresson, Jr, [red; "6366 Ditrichophora PAINTERI" handwritten]/1182." The holotype is double mounted (minuten pin in a block of fine foam), is in excellent condition, and is deposited in the ANSP (6366). Three paratypes (2♂, 1♀; ANSP) bear the same locality label as the holotype.

Remarks.

Although similar to Lamproclasiopa balsamae , this species is distinguished from that species and all other congeners by having a conspicuously spotted wing, as in Lamproclasiopa balsamae , and by having the mesonotum with four stripes, each as a short series of two to four more or less elongated spots. In Lamproclasiopa balsamae there are seven distinct and complete or nearly complete stripes. Structures of the male terminalia also distinguish this species.

The illustration of Lamproclasiopa balsamae that Mathis and Zatwarnicki (2001) published is actually that of Lamproclasiopa painteri .

The locality of the specimen from Venezuela is a mystery to us. We have checked and rechecked the spelling on the label, “Caife,” but have been unable to locate this name on maps or gazetteers. Perhaps it is a misspelling.
