( Figs 6AView FIGURE 6, 7View FIGURE 7)

Masteria hirsuta L. Koch, 1873: 458  , pl. 35, fig. 5; Simon, 1892: 190, fig. 131; Roewer, 1963: 109, fig. 2a –d (male); Raven, 1979: 627, figs 5–7.

Type. FIJI. ♀ holotype, Ovalau , Fiji (17°41’17”S; 178°47’26”E), deposited in ZHM, examined by photos).GoogleMaps 

Additional material examined. FEDERATED STATES OF MICRONESIA: Yap: Yap Hill, (9°32’0”N; 138°7’0”E), 03.XII.1952, 1♀, J. L. Gressit leg. (BM 17418)GoogleMaps  ; Ponape: (6°53’0”N 158°14’0”E), 07.I.1953, 2♀, 1 immature, J. L. Gressit leg. (BM 1 7516); Monte Tamatamansakir, (6°53’0”S; 158°14’0”E), 17.I.1953, 1♀, J. L. Gressit leg. (BM 17511).GoogleMaps 

Diagnosis. The male of Masteria hirsuta  from Micronesia is similar to those of M. toddae  and M. franzi  from the islands of Pacific Ocean; they differ in the absence of paraembolic apophysis. The male resembles those of the Neotropical species M. barona  , M. petrunkevitchi  and M. soucouyant  n. sp. in the elongated bulb, but differs from M. petrunkevitchi  and M. soucouyant  in the absence of grouped spines retrolaterally on the palpal tibia ( Fig. 7BView FIGURE 7). In addition, it resembles those of M. barona  in the absence of spines on the palpal tibia but differs in the slight medial curvature on embolus ( Fig. 7BView FIGURE 7). Females are similar to those of M. golovatchi  in the strongly projected spermathecae base, but differ in the short lobes and developed GR ( Fig. 6AView FIGURE 6).

Note. The four examined females have the same eye pattern described by Raven (1979), i.e. six eyes, large PME, with a strongly recurved back row, and with small separation between the anterior laterals, and a compact and wide group of eyes. Our eye description was based on photos of the holotype, MEV pictures from the Micronesian specimens, and hardly differs from those of Raven`s description (1979, fig. 5).

Remarks. The type specimen is herein included for a comparative purpose. Specimens of Masteria hirsuta  collected in Micronesia (over 1000 km from Fiji) and studied by Roewer (1963) are also included. We present the diagnosis and drawings of the species`eyes and genitalia of the non-type in order to compare the morphology to the remaining Neotropical species of Masteriinae  .
