Camptomyia parrishi ( Felt, 1915)

( Figs 4–5 )

Felt 1915: 152, described as a Porricondyla .

Holotype. Male, Guyana, Bartica, 27 Dec. 1912, H.S. Parrish ( NYSM).

Remarks. The lectotype is a pale, incomplete and partially distorted specimen; its genitalia, visible in a ventral aspect, are somewhat compressed.

Male description. The following character states could be determined. Head. Scape lighter than both pedicel and flagellum. Eleven flagellomeres retained; fourth flagellomere with neck 1.3 × node, neck basally with microtrichia. Legs. Empodia broad, slightly shorter than claws. Terminalia. Tergite IX subtriangular, posterior margin apparently straight (a small medial notch is presumed to be an artifact), apodeme elongate, situated basally. Gonocoxites broad; ventral emargination deeply U-shaped, at base membranous and with small setae in two groups; anterior portions of gonocoxal apodemes thin, shorter than distance separating them. Gonostylus evenly curved, evenly tapered toward apex, a pectinate claw of normal size apicodorsally ( Fig. 5 ). Copulatory organ ( Fig. 4 ): base of ejaculatory apodeme T-shaped, apical portion slightly widened. Parameres protruding clearly beyond copulatory organ, apices broad compared with other species of corticalis group, directed posteriad, paramere processes comparatively thick, straight, acuminate, ending slightly below apex of copulatory organ ( Fig. 4 ).

Classification. Camptomyia parrishi is a member of the C. corticalis species group. This group contains about 10 named species from the Holarctic Region ( Jaschhof & Jaschhof 2013) and at least 5 presumably unnamed species that were recently found in Costa Rica (Jaschhof, unpublished). Many more species of this group are expected to exist. In males, the gonocoxites are broad, the gonostylus is slender and slightly curved, and the parameres have a subapical pair of short sclerotized processes ( Jaschhof & Jaschhof 2013). Many of the species belonging here are known from a single or few specimens, often only the types, so characters to distinguish among different species are generally poorly studied. As far as is known, the morphological differences between species are slight and usually concern the outline of the ninth tergite, gonocoxal emargination, gonostylus, and parameres plus copulatory organ. The taxonomy of the corticalis group is in need of a thorough study, yet this is impossible to perform without drawing upon larger series of fresh specimens of both sexes.
