Genus Schendylops Cook, 1899

DIAGNOSIS. — Pleurites of second maxillae not fused to the coxosternum. Apical claw of second maxillae pectinate on both d. and v. edges . Sterna with pore

fields. Last pair of legs with seven podomeres; praetar- sus in form of a small hirsute tubercle or replaced by a small spine or altogether absent. Coxopleura of the last leg-bearing segment each with two internal coxal organs of simple structure (“homogeneous coxal glands” sensu Brölemann & Ribaut 1912).

TYPE MATERIAL EXAMINED. — Holotype Ƌ, reference “ Haploschendyla insolita ”, 75 p. l., body length 35 mm, from Madagascar: Moramanga , forêt à Niagarakely, XII.1955, R. F. Lawrence leg. ( MNHN coll. Myriapodes 127). Cephalic capsule and mouth parts in one original slide, trunk in alcohol. Lawrence stated in his original description: “ Holotype ♀ ”, but this is evidently a typographic error as his description is clearely based on a male specimen.

TYPE LOCALITY. — Madagascar: Moramanga, forêt à Niagarakely.

DISTRIBUTION. — Madagascar: Moramanga: Niagarakely.

DIAGNOSIS. — A Schendylops species with v. pore fields extending along the whole body length. Of the other Schendylops species in Madagascar, this trait is present only in S. mascarenicus ( Lawrence, 1960) and S. grandidieri ( De Saussure & Zehntner, 1897) . Characters in Table 5 and in the key differentiate Schendylops insolitus from these two species and from the other Madagascar congeners.

REDESCRIPTION

Male holotype. 75 p. l., body length 35 mm; maximum body width 1.0 mm. Colour of preserved specimen pale orange.

Antennae c. 2.0 times as long as the cephalic plate, distally slightly attenuate. Setae on a.a. I-VI of different length and few in number, those of remaining articles progressively shorter and more numerous towards the tip of the appendage ( Fig. 1A ). Terminal a.a. with c. 21 claviform sensory setae on external border, c. six on internal border ( Fig. 1B ). Distal end of this a.a. with c. seven very small specialised setae, apparently
