DELFINADO: LAELAPTOID MITES OF THE PHILIPPINES 97 



Holotype. Female, ex Apomys insignis insignis. Mindanao: 

 Eastern slope of Mount McKinley, 5500 ft. elevation, August 20, 

 1946 (H. Hoogstraal). In the Chicago Natural History Museum 

 collection. 



Laelaps hirtus, new species. Figure 29, A-C. 



The distinguishing characters of this species are as follows: The 

 distal and proximal setae on coxae I, II and III are long and slender; 

 the distance between the epigynial setae IV is greater than the dis- 

 tance between setae I; the second pair of vertical setae is tiny, and 

 there is a pair of long, posterior, marginal dorsal setae. 



Fig. 29. Laelaps hirtus, female: A, anterior portion of dorsal plate; B, pos- 

 terior portion of dorsal plate; C, venter. 



FEMALE: Gnathosoma with medial hypostomal setae longer than lateral and 

 gnathosomal setae; chelae toothed; pilus dentilis slender, with bent knobbed apex. 

 Dorsal plate 575 /x long, 383 /x wide; second pair of vertical setae tiny, medial setae 

 shorter than marginal setae, and a pair of much longer posterior marginal setae. 

 Sternal plate wider than long, the posterior margin concave; sternal and meta- 

 sternal setae short, subequal in length. Epigynial plate dropnshaped, rounded 

 posteriorly; the distance between setae IV greater than the distance between 

 setae I. Anal plate wider than long, almost as wide as and closely separated from 

 epigynial plate; adanal setae reaching base of postanal seta. Metapodal plates 

 small, rounded. Venter with 6 pairs of moderately long setae laterad to epigynial 

 and anal plates. Peritreme extending beyond middle of coxa I. Both distal and 

 proximal setae of coxae I, II and III long and slender, not spinelike. 



MALE : Unknown.
