Distribution. Southwest Western Australia, north to Eneabba (29°50'S 115°15'E), east to Cocanarup (33°38'S 119°54'E) ( Fig. 1), sclerophyll forest.

Discussion. Henicops dentatus   is identical to or within the range of variation of H. tropicanus   , described in full below, in most respects except for the female gonopods and details of the mandibular gnathal edge. Distinction between the two is discussed under the latter species.

The present study of a large sample of southwest Western Australian specimens of Henicops   , including the syntypes of both H. dentatus   and H. oligotarsus   , corroborates Archey’s (1937) suspicion that the two named Western Australian species are synonymous. When naming H. oligotarsus, Attems   made no mention of the previously named H. dentatus   . Attems (1928:63) later acknowledged H. dentatus   in a key to Henicops species.   He distinguished the two Western Australian species on the basis of tergites 7, 9, 11 and 13 of H. oligotarsus   being “toothed” and the corresponding tergites of H. dentatus   and H. maculatus   being “rounded”, in addition to leg 15 of H. oligotarsus   having five tarsomeres as opposed to six tarsomeres in H. dentatus   and H. maculatus   . Both of these alleged differences are unfounded. Description of a “toothed” condition of tergites in H. oligotarsus   refers to the triangular projections of the posterior angles of TT7, 9, 11 and 13. This is a more or less accurate description of the tergites of Attems’ specimens ( Fig. 3A), but it is identical to the condition of these tergites in the types of H. dentatus   ( Fig. 3B). Indeed, no Henicops   specimens from anywhere in the range of H. dentatus   (= H. oligotarsus   ) have tergites 7, 9, 11 and 13 that could be described as “rounded”. Leg 15 of all Western Australian specimens has five tarsomeres ( Fig. 4D) so no specific distinction can be made based on some specimens having five and others having six. The types of H. dentatus   lack legs 14 and 15 (and seemingly lacked these legs when Pocock described the species, for no mention was made of them), so Attems’ claim of a difference from H. oligotarsus   has no basis. In the absence of any morphological characters to support the presence of multiple taxa in Western Australia, all specimens are recognized as a single species, using the older name, H. dentatus   . The description of H. oligotarsus ( Attems, 1911:150)   stated that the species has 33–35 antennal articles but among the syntypes are large specimens with 29–36 articles. Other collections extend the range to 38 articles, though as in H. tropicanus   the most common number is 36.
