status

sp. nov.

Engelimyia psino Pape & Mello­Patiu , sp. nov.

Figs 23–30, 41

Sarcophaga cassidifera: Hall (1933) , Dodge (1968); misidentification.

Etymology

The species epithet psino is an anagram of inops , thereby stressing the similarity and possible sister­group relationship between the present species and Engelimyia inops . The name should be treated as a noun in aposition.

Type material

Holotype 1 ♂, COSTA RICA: Prov. Limón, Res. Biol. Hitoy Cerere, 100–200 m, 1991, in Malaise trap INBIO 926596 ( INBio). Paratypes— Costa Rica: 1 ♂, Prov. Limón, Valle La Estrella, 100 m, 19–29.iv. 1992, E. Lopez, INBIO 716301 ( ZMUC); 1 ♂, Prov. Limón, Fca. De E. Rojas, Sector Cerro Cocori, 9–30.xi. 1992, E. Rojas, INBIO 899236 ( MNRJ).

Description of adult male

Like E. bosqi but differing by the following: Head: Frons at vertex 0.22 x head width; frontal row of 11–12 bristles; arista long plumose in basal 0.75. Thorax: Meropleurals 8–9; mid femur with a row of 3–4 median anterior bristles and 1–2 median anteroventral. Abdomen: ST 5 with a conspicuous median projection, which in lateral view has an almost vertical anterior margin; outline of posterior half almost quadrate in lateral view, but with the ventral margin sinuous ( Fig. 27). Anterior margin broadly U­shaped, postero­lateral lobes slender and almost parallel­sided at base ( Fig. 28). Terminalia: Cercus with strong setae on mid lateral margin and small setulae apically, in profile with almost straight dorsal margin, without subapical dorsal hump, and with abruptly rounded or truncated apex ( Fig. 25). Cerci in posterior view symmetrical and with the tip of each cercus slightly recurving laterally ( Fig. 24). Surstylus with apex strongly modified into a large, saddle­like, bifurcated structure narrowly attached to the remaining surstylus; the two prongs of the tip distinctly visible in lateral view ( Fig. 26). Surstylar base proximal to the bifurcated tip almost quadrate. Pregonite about as long as postgonite, straight, with very shallow concavity on basal margin and an apical notch; postgonite very slightly curved and with a strong bristle medially on anterior margin ( Fig. 29). Phallic tube with ventro­lateral margin projecting into a rectangular structure with small spines distally ( Figs 30, 41); juxta shaped as a pair of short, straight posterior apophyses almost hidden under the large, membranous apical structure, which is extensively spinose; vesica triangular in lateral view and with spinose proximal surface; lateral styli with base expanded into a large, gently curved, plate­like structure with its greatest width subapically ( Figs 30, 41).

Distribution

Neotropical—Costa Rica, Panama.

Remarks

Hall (1933) mentioned two males of Sarcophaga cassidifera caught 5.vi. 1929 on Barro Colorado Island, Panama, by C.H. Curran, and Dodge (1968) referred to a single male of S. cassidifera also from Barro Colorado Island, “ 1.VII. 1956, no. 2254, sweeping in forest (KU)”. None of these specimens were located during the present study, but the material certainly belongs to E. psino as judged from the evidently bifid surstylus in the illustration made by Hall (1933, fig. 12).
