Diagnosis — Postocularia more or less in a line with the three dorsal pairs of glandularia; Cxgl- 4 fused with ventral shield in male, but separated in female. Fourth legs of male with sexual dimorphism.
Description — Male: Idiosoma yellowish, dorsally 413 (389 – 393) long and 298 (284 – 296) wide, ventrally 397 (356 – 365) long. Dorsal shield 404 (379 – 381) long and 251 (235 – 251) wide, with three pairs of glandularia; postocularia posteriorly of dgl- 1, more or less in a line with the three dorsal pairs of glandularia. A2 not fused with dorsal shield. Three pairs of relatively small glandularia platelets in dorsal furrow. Coxal suture lines incomplete. Cxgl- 4 halfway between insertion of IV-leg sockets and genital field. Gonopore 28 long. Genital field fused with ventral shield, with three pairs of glandularia. Vgl-4 fused with ventral shield. Length of P1-5: -, 38, 36, 54, 30. Length of I-leg-4-6: 66, 62, 64 (till tip of segment). Length of IV-leg-4-6: 73, 62, 66 (till tip of segment); IV-leg-5 anterodorsally with a large curved seta. Swimming setae absent.
Female: Idiosoma yellowish, dorsally 437 (405 – 454) long and 348 (316 – 356) wide, ventrally 397 (373 – 413) long. Dorsal shield 421 (385 – 429) long and 279 (259 – 280) wide, with three pairs of glandularia. Configuration of dorsal glandularia and postocularia as in male. Three pairs of relatively small glandularia platelets in dorsal furrow. Coxal suture lines incomplete. Cxgl-4 halfway between insertion of IV-leg sockets and genital field. Genital field 160 wide, with thee pairs of glandularia, connected by a small strip of sclerotization. Excretory pore not fused with this strip. Vgl-4 lying free lateral of genital field. Length of P1-5: 20, 28, 38, 50, 34. Length of I-leg-4-6: -, 49, 50 (till tip of segment). Length of IV-leg-4-6: 60, 64, 56; no special setae present on IV-leg-5. Swimming setae absent.
Etymology — Named for the dorsal glandularia and postocularia lying in a line.
Remarks — No other
Javalbia
species
has the postocularia lying in a line with the dorsal glandularia. Moreover, the sexual dimorphism of the fourth leg is not found in other species of the subgenus
Javalbia
.
