Galumnidae JACOT, 1925 G alumna flabellifera HAMMER, 1958 - Localities: 3746: 3 specimens, 3757: 3 specimens, 3988: 2 specimens. Distribution: Circumtropical. First record for Yemen. Pilogalumna arabica BAYOUMI ct AL-KHALIFA, 1986 - Localities: 543: 15 specimens, 1773: 1 specimen. Distribution: Saudi Arabia. First record for Yemen. DESCRIPTIONS OF NEW TAXA Austrocarabodes latissimus sp. n. (Figs 1-6) Materied examined - Holotype: Yemen 3884, 12 paratypes: from the same sample. Holotype and 7 paratypes deposited in the MHNG; 5 paratypes deposited in the HNHM (1642-PO-99). Description - Measurements: Length: 607-778 pm, width: 412-559 p.m. Prodorsum: Rostrum wide, roundish in dorsal aspect, finely alveolate. Prodorsal surface covered by pustules. Lamellae narrow, well covering the lamellar part of prodorsum, their surface rugose. Rostral, lamellar and interlamellar setae dilated, lamellar setae phylliform with serrate margin (Fig. 5). Rostral setae arising on a transversal crest (Fig. 6), they have two, the much longer interlamellar setae one veil. Interlamellar setae arising medially, conspicuously near to each other. Sensilli short, their head enlarges like a brush, with thick spines on their dorsal surface (Fig. 3). Lateral part of prodorsum: Tutorium well developed, without apex. Lateral surface of prodorsum ornamented by large alveoli. Sejugal region and the surface over the acctabula finely granulate. Pedotecta I large, finely alveolate. Notogaster (Fig. 1): Evenly convex. Humeral part of notogastcr slightly protruding. The surface of notogaster covered by pustules - excepting roundish, smooth fields around the insertion of the notogastral setae. All fourteen pairs of notogastral setae lanceolate (Fig. 4), with two veils on their dorsal surface. Among them four pairs arc comparatively short, also phylliform, arising in posteromarginal position. Ventral parts (Fig. 2): Setae h simple and short, originating near each other. Coxisternal region with partly hardly observable apodemes and cpimcral borders. The posterior borders of the epimeral region indistinct, undulate. Between the epimeres a wide median field present, with a framed hollow in sejugal region. Epimeral surface with some sigilla. All epimeral setae very fine, simple. Setae lc arising far medially from pedotecta 1. Anogenital region with rough sculpture consisting of ribs and crests. Anogenital sctal formula: 4-1-2-3. Genital and anal apertures located in normal position. Genital and aggenital setae simple, anal hardly, adanal ones well dilated, phylliform. Setae ad, in postanal, acb in paraanal, setae ad> in preanal position. Lyrifissures well visible, located far from the anal opening, in front of setae adi. Legs: Chaetotaxy of legs: 1: 1-4-3+1-4+2-15+2-1 IV: 1-2-2-2+1-1-12-1 Solcnidium cp> stands far posteriorly from (p., <p, of tibia IV very short. Femora and trochanters of legs III and IV with blade-like ventral formation, ending in a distal spur. Setae /" of genu l-l V phylliform. Trochanter and femur of legs also bearing phylliform setae. Setae p and u of tarsi I-IV simple, setiform.
