Allonothrus pyriformis View in CoL (Berlese, 1913)

Angelia pyriformis Berlese , 1913, p. 99, pl. 8 fig. 91; Lombardini, 1936, p. 38.

The specimens in the Berlese Collection are in a bad condition. There are six slides (nos. 135/20-25) that bear different labels: 21 and 22 are juveniles; 20, 23, and 25 are designated as type; on 21 and 22 the locality is indicated as Java only; 21, 23, 24, and 25 are from Semarang, Java; nevertheless, it is evident that the six slides represent the type-material. Of this material no. 135/22 is the single one that is suited for study; the specimen is identical with Berlese's description and figure. Because the identity of the remaining specimens is not completely certain, I designate the specimen in slide no. 135/22 as lectotype.

I noted the following striking differences from A. schuilingi . The present species is larger (length according to Berlese 0.600 mm, according to my own data 0.690; in schuilingi 0.435). The general shape of the body reminds of Trimalaconothrus . The sensillus is only very slightly thickened towards the end. The dorsal hairs are generally longer and slimmer; ps2 is an ordinary hair, not fan-shaped. The structure of the notogaster is different; in schuilingi the central area of the notogaster is elevated and at each side bordered by a groove, whilst the reticulations are absent or indistinct in the anterior lateral part and in small areas around the hairs.
