Description ( Fig. 12 View FIGURES 10–23 )

Body length 2.7 mm. Bristles yellow. Acrostichal bristle absent. Thorax yellow with central stripe (flared anteriorly, and sometimes strongly reduced centrally leaving thin median line), one pair of oblique stripes behind suture laterally and with scutellum and laterotergites brown. Pleuron yellow with dorsal and posterior sutures of anepisternum brown. Legs yellow, with coxae light yellow. Posterior 2/3 of frons brown with wide yellow anterior emargination; antenna yellowish­white (excluding arista); gena white and silvery­tomentose; remainder of head yellow; anterior 2/3 of frons with median triangular pilose patch. Abdomen brown with cerci yellow. Distal 1/3 of wing dusky.

Female

Unknown.

Male terminalia ( Figs. 103–105 View FIGURES 103–105 )

Annulus well developed. Length of epandrium 0.7 times height and width subequal to height. Surstylus 0.7 times height of epandrium; triangular with posteroventral lobe; twisted so that distal half of inner face visible posteriorly; inner face densely bristled, with numerous conical tubercules along distal half. Cerci largely united and ovate with deep medial emargination; apical bristles longer. Pregonite expanded distally into bare posterior lobe (emarginate anteriorly) and setulose anterior lobe; one small and two strong medial bristles. Phallapodeme stout and 0.6 times length of hypandrial arm. Distiphallus long and membranous (straight on basal half) with several medial and distal sclerotizations.

Etymology: The specific name refers to the collection locality.

Distribution: Brazil, Peru (Map 10).

Holotype: PERU. Loreto: Iquitos (14km W), W. Mathis, 16.ii.1984, (1♂, USNM).

Paratype: BRAZIL. Estado Mato Grosso, S' Sinop, N' Curitibá (about 490 km road distance), N' Sorriso , Facienda Sant' Ana , eastern roadside, rainforest, collected from human excrements, 8.iii.1986, M. v.Tschirnhaus (1♂, ZSMC) . PERU. Loreto: Iquitos (14km W), W. Mathis, 21.ii.1984 (1♂, USNM; 1♂, DEBU) .

Comments: A strong longitudinal stripe (sometimes reduced medially) and one pair of thin abbreviated transverse stripes behind the transverse suture characterize Craspedochaeta loreto . This species resembles C. trivittata , but it is significantly smaller, the head, wing, pleuron and legs are weakly pigmented, there are two pairs of lateral scutellar bristles, and the transverse notal stripes are directed anteriorly.
