Transeius katumaniensis Zannou, Moraes & Oliveira , n. sp.

( Fig. 21 )

DIAGNOSIS—Dorsal shield mostly reticulate; ratios s4:Z1 = 4.2, s4:S2 = 2.4; seta z4 shorter than z2 and about half as long as distance between its base and that of s4. Spermatheca with calyx bell-shaped.

FEMALE—(Specimen measured—Kenya: 1).

Dorsum ( Fig. 21 A)—Dorsal shield mostly reticulate, except for the smooth anterocentral region, 349 long and 187 wide. Setae j1 26, j3 37, j4 13, j5 13, j6 11, J2 11, J5 10, z2 22, z4 18, z5 10, Z1 13, Z4 64, Z5 83, s4 54, S2 22, S4 13, S5 11, r3 26, R1 18. Setae smooth, except Z4 and Z5, serrate.

Peritreme—Extending forward to level of j1.

Venter ( Fig. 21 B)—Sternal shield mostly smooth, with few lateral striae; posterior margin indistinct; distances between St1-St3 64, St2-St2 64. Genital shield smooth; distance between St5-St5 62. Ventrianal shield smooth, anterior margin slightly convex, 120 long, 85 wide at level of Zv2 and 77 wide at level of anus; preanal pores small and posteromesad to Jv2.

Chelicera ( Fig. 21 C)– Movable digit 34 long, with 2 teeth; fixed digit 29 long, with 7 teeth and a pilus dentilis.

Spermatheca ( Fig. 21 D)—Calyx bell-shaped, 10 long and ca. 11 in diameter near vesicle; atrium nodular.

Legs—Macrosetae: Sge II 18, Sge III 18, Sge IV 34, Sti IV 22, St IV 42. Chaetotaxy: genu II: 2-2/1,2/0-1; genu III: 1-2/1,2/0-1.

MALE—Unknown.

LOCALITY AND TYPE MATERIAL—Holotype female from unknown plant, Machakos, Katumani, Kenya, 30-IX-1990, C. Kariuki, deposited at ESALQ-USP.

ETYMOLOGY—The epithet katumaniensis refers to the location (Katumani) where the type of this species was collected.

REMARKS— Transeius bellottii ( Moraes & Mesa, 1988) differs from this species by having j3 and s4 serrate and macrosetae only on leg IV. Transeius jailensis ( Kolodochka, 1981) , T. tuvinensis ( Beglyarov & Meshkov, 1988) and T. violini ( Meyer & Rodrigues, 1966) differ by having dorsal shield mostly smooth, with some lateral striae. In addition, T. jailensis has Z5 ca. 1.8 and ca. 2.7 times as long as Z4 and s4, respectively; T. tuvinensis has ventrianal shield striate and calyx of spermatheca narrower (ca. 0.5 time as wide as long); and T. violini has ventrial shield also striate and calyx of spermatheca swollen basally, bladder-like, then narrowing and flaring distally.
