Type material.

Holotype female, labeled: "Manchi Ecuador/7000 ft/22-XI" [no year, but given as 1910 in description], "CHT Townsend/ Collector", "Below/ Manchi Ec/Nov 22", "Type No. 22247/U.S.N.M.", " Machairomasicera / carinata /♀ Det CHTT 1", " Eucelatoria / carinata (Townsend)/ det. D.J. Inclán / & J.O. Stireman" (NMNH).

Recognition.

This species can be distinguished from Eucelatoria flava sp. n. and Eucelatoria obumbrata by the entirely black coloration of the abdomen, which contrasts with the entirely yellow abdomen of Eucelatoria flava , and the yellow and black abdomen of Eucelatoria obumbrata . It also differs from females of Eucelatoria obumbrata in having sparsely haired eyes, more densely bristled palpi, strongly infuscated wing veins, and a bronze tinted parafacial (dull silver in known females of Eucelatoria obumbrata ).

Redescription.

Length: 6.7 mm.

As described for Eucelatoria obumbrata except for:

Head (Fig. 11): Eye sparsely, but long-haired. Eye 0.83 head height. Vertex width, at its narrowest point 0.26 head width. Length of first flagellomere 0.44 head height. Width of first flagellomere 4.6 parafacial width at its narrowest point. Pedicel length 0.28 length of first flagellomere. Fronto-orbital fig with 4-6 medioclinate frontal setae. Facial ridge with hairs on basal 1/2, but short and fine above basal 1/3. Posterodorsal part of the head without black setae behind the postocular row.

Thorax (Fig. 11a, b): Scutum with 3 presutural acrostichal setae and 3 postsutural acrostichal setae; 2 presutural dorsocentral setae and 3 postsutural dorsocentral setae; 1 presutural intra-alar seta, with 1 additional small seta; 3 postsutural intra-alar setae. The first postsutural supra-alar seta present but reduced in size.

Wing moderately fumose on anterior half around veins C, Sc, R1 and R4+5, light infuscation also present along veins M, CuA1, and dm-cu. Wing vein R4+5 dorsally setose from its base until nearly the crossvein r-m, and R1 bare.

Abdomen (Fig. 11a, b): Entirely black in ground color with transverse bands of sparse white pruinosity on basal 1/3 of tergites 3 and 4, and 1/2 of tergite 5. Median discal setae absent.

Geographic distribution and seasonal occurrence.

The only known specimen of Eucelatoria carinata was collected in Ecuador. The specimen was collected in the Andes Mountains at about 7000 ft (2100 m). The locality of the specimen reads "Below Manchi", but it is unclear what this name refers to.
