Allozercon (Philippinozercon) ( Gerdeman, Garcia, Herczak & Klompen 2018) n. comb.

Philippinozercon Gerdeman, Garcia, Herczak & Klompen (2018) : 10

[type species: Philippinozercon makilingensis Gerdeman, Garcia, Herczak & Klompen 2018 , by original designation].

Diagnosis. Axial outgrowth of palp trochanter in male distinct and membranous (9, reversal?); palp genu seta pl absent in adults (13); anterior dorsal setae j1 minute (<5 µm) (28.2, with few reversals); distinct curved, sclerotized ridge on anterior margin of female genitiventral shield present (46; shared with Heterozercon ); postero-lateral margin of metapodal shields appears cut off, with sharp angle (61), setae S 5 in male minute (75).

Remarks. In terms of the number of unique characters, Philippinozercon has more apomorphies than the majority of heterozerconid genera. Even so, it consistently appears as nested within Allozercon , and is therefore reclassified as a subgenus of Allozercon .

Allozercon (P.) makilingensis is one of only two species of Heterozerconidae for which all immature instars have been described ( Gerdeman et al. 2018). Basic phenology of this species was described in Gerdeman & Garcia (2009(2010)).
