Simulium (Hearlea) nigricorne Dalmat View in CoL

Figs. 4 L–N View FIGURE 4 .

Simulium (Hearlea) nigricornis Dalmat, 1950: 148–151 , Figs. 15–20; 1955: 76, 82, 273–275, Figs. 115, 235–236, 315, 355.

(Diagnosis of female and male derived from Dalmat, 1955).

Female: General coloration unknown. Cibarium with a definite indentation along internal margin. Cerci about 2 times wider than high with curved border, anal lobe with abundant hairs distally; genital fork with median rod thin, elongate.

Male: General coloration unknown. Basistylus with strong prominence basally along internal border; ventral plate with small median carina.

Pupa: ( Figs. 4L–N View FIGURE 4 ). Cocoon shoe shaped, with reinforced anterior margin; length (basal), 2.9 mm; maximum, 3.6 mm. Frontoclypeus with few platelets. Thorax with numerous granules. Gill extended well beyond anterior margin of cocoon, comprised of 2 subannulated, laterally compressed branches; dorsal branch with distal 3/4 darkened, distended and blunt apically; ventral branch elongate, curved, distally tapered, with small distally digitiform projection. Abdominal tergite X lacking terminal spines.

Larva: unknown.

Material examined: Guatemala: (Dalmat collection, USNM) Chimaltenango, Acatenango, río Laguneta , Fca. Tehuyá, 1 pupa (paratype), 29 March 1949 , Luch ; 1 pupa (paratype, cocoon only), 26 February 1949 ; 1 pupa (paratype), 25 September 1949 .

Distribution: Guatemala: Chimaltenango.

Discussion: The presence of two annulate gill branches places S. ayrozai , S. ethelae and S. microbranchium close to S. nigricorne , but the short, wide, distally darkened dorsal branch permits their separation. In two paratype pupae, the darkened apex gill dorsal branch mentioned by Dalmat was not observed.
