Figs. 13 , 33, 34 , 61, 62 , 85, 86 , 120–122 , 134 , 146 , 158 , 159 , 161 Tables 1, 2

Diagnosis. Gena with dark setae; upper and lower calypters dark in both sexes; basicosta brown; setae below and behind strong postocular row pale and weak; presutural area of thorax usually with a broad band of whitish microtomentum, in some specimens the microtomentum is patchy. This species shares many characters with L. pulverulenta , but the former has pale setae on the gena, while L. woodi has all dark setae on the gena. In lateral view, the surstylus of L. woodi ( Fig. 61 ) is broader than in L. pulverulenta ( Fig. 53 ).

Description. Male. Frons narrow, 0.017 (0.01–0.02/5) of head width at narrowest; anterior facets are 2.4x larger than posterior facets (anterior 0.67mm, posterior 0.28mm, Table 1); fronto-orbital plates are silvery-tan, plates converge midway up frons; frontal vitta dark red, extending about one-third up frons to where fronto-orbitals touch, frontal setae end about one-half way up frons; parafacial silvery-tan except anteroventral corner more or less orange; gena silvery with dark setae, postgena silvery with pale setae; pedicel dark orange with base of first flagellomere brighter orange, remainder pale orange; ocellar triangle tiny and black with short setae, ocelli about equal in size; supravibrissal setae ascend about 40% up frontal ridge; intrapostocular area bright silvery, setae below and behind postocular row pale and weak except for a small cluster of dark setae near the lower edge of the eye; upper edge of occiput and a vertical strip in the center shining black, remainder of occiput with whitish microtomentum. Presutural area of thorax with heavy microtomentum, remainder of thorax shining; spiracles brown and fairly large; proepisternal depression with pale setae; upper calypter light tan to brown, lower calypter brown to dark brown; base of wing with cells and veins darkened; basicosta dark brown, tegula black; subcostal sclerite orange with pubescence. T1-3 of abdomen and anterolateral corners of T4 with whitish microtomentum, with the remaining segments polished. Surstylus medium length, digitate, gradually expanding toward distal end, cercus tapers distally and gradually curving forward ( Figs. 61, 62 ). Phallus, hypandrium, pre- and postgonite, ejaculatory sclerite, and sternites as in 85, 86, 120–122, 134 respectively.

Female. Characters very similar to male except frons 0.24 (0.22–0.25/5) of head width at narrowest; eye facet size very similar to those in male (anterior 0.59mm, posterior 0.29mm, Table 1). The ovipositor and spermathecae as in Figs. 146 , 158 .

Distribution. Costa Rica, Honduras, and Panama ( Fig. 159 ).

Discussion. About 20% of the specimens that keyed to this species had patchy microtomentum on the presutural area of the thorax, not a solid band (similar to Fig. 14 ), all from Costa Rica. Originally, this was thought to be a separate species, but other characters for both sexes appeared to be very similar. For now, this condition is considered intraspecific variation. A few specimens of Lucilia , primarily from southeastern Brazil keyed to this species, but clearly are not, based on male genitalia. Not enough good material was available to determine if these specimens belong to an undescribed species, or if they are aberrant examples of an existing species. Two specimens that keyed to this species produced barcodes that were widely separated. This is either a vaiable species, or possibly a species complex. Further study is needed to explain the variation observed ( Fig. 161 ).

Etymology. The species name was chosen to honor D. Monty Wood who encouraged me to work on the taxonomy of this difficult genus in the Neotropics and has been a dedicated student of Diptera for over half a century.

Erratum

In the Whitworth publication on calliphorids of the West Indies (2010: 10, 11), the author mistakenly labeled the proepimeral seta which is present or absent in some Chrysomya as “proepisternal seta”.
