Diagnosis: Reclinate orbital setae longer than proclinate; surstylus slender, with slender prensisetae; distiphallus with fine lateral and medial serrations only, without dense, long medial setulae; oviscapt with ventral row of 5–6 small pegs anterior to preapical seta (vs. row of 9–10). Abdominal apex dark.

Description: Body coloration typical of group, except that male tergites 7 and 8 dark. Reclinate orbital seta longer than proclinate. Protarsal spines 8, sizes alternating in usual series. Male genitalia: Epandrial lobe with 1 short, apical spine; surstylus small and slender, prensisetae fine, 12, not crowded (bases not touching); aedeagus having distiphallus with fine lateral and medial serrations only, without dense, long medial setulae. Oviscapt with apical notch well defined, size of pegs in ventral pair approximately equal to those in dorsal triad, ventral series with 5–6 small pegs.; surstylus slender, with slender prensisetae;; Measurements: (Based on HS01): Head: HD/HW 0.79; FL/LFW 1.35; VB2/VB1 0.58; EW/ED 0.71; OR2/OR1 1.16; OR3/OR1 1.25; OC/POC 1.55; FW/FD 0.56; ODB/ ODA 0.40; Thorax: ThL 0.78 mm.; LHS/ThL 0.21; ADC/PDC 0.45; AKE/PKE 0.52.

Holotype: See Burla (1954) in Zoological Museum of the University of Zurich, Switzerland. Not examined.

Other Specimens: Male, HS-01, “Coll. H. Burla, Côte, d’Ivoire, 1951/ D.? suma, M. Bettie 1951 .” Female, HS- 02, “Coll. H. Burla, Côte, d’Ivoire, 1951/ D.? suma, M. Bettie 1951 .” Both minuten double-mounted, in AMNH.

Comments: We did not study the type specimen in Zurich, but we had available a male and female in the AMNH collected by Burla from the same or similar series from the Ivory Coast. In Burla’s (1954: fig. 217) diagram of the oviscapt he shows 5 small pegs in the ventral series, a rare feature to which our diagnosis conforms. The schematic diagram of an oviscapt by David et al. (2011) showed a row of 7 such small pegs, but they did not indicate the origin of the specimen. Their diagram of the male genitalia (David et al., 2011) is too basic to determine species identity. These authors and Prigent et al. (2020) mentioned that D. suma has a widespread distribution in Africa and islands of the Indian Ocean, which we have not been able to confirm.
