Genus TENAPHALARA Kuwayama 
Tenaphalara Kuwayama, Trans. Sapporo Nat. Hist. Soc. 2 (1908) 154. 
Strogylocephala Crawford, Philip. Journ. Sci. § D 12 (1917) 166. 
Body elongate, slender; head not much deflexed, nearly or 
quite as broad as thorax; vertex more or less rounded forward 
and downward, with anterior ocellus at front end of head and 
antennse inserted at end on each side of front ocellus; gense not 
produced into cones, slightly swollen beneath antennal sockets, 
usually not wholly covering frons, antennae slender; eyes hemi- 
spherical, not recessive. 
Thorax slender, not arched; legs slender, often rather long. 
Forewings long and narrow, more or less acutely pointed ; vena- 
tion of Carsidarinae type, with two pseudoveins or calluses; 
pterostigma present. Abdomen long and slender. 
Type of the genus, Tenaphalara acutipennis Kuwayama. 
This is rather an anomalous genus, suggestive of Aphalara 
and also Pauropsylla in the head shape, and of Carsidarinae in 
wing venation, tarsi, and eyes. Kuwayama placed the genus 
at the end of his subfamily Aphalarinae, but the majority of the 
characters point rather to an affinity with Carsidarinae. Al- 
though the head is not cleft in front, as in Carsidara, never- 
theless this genus is now referred to the subfamily Carsidarinae. 
This is a tropical subfamily and many forms doubtless remain 
undiscovered. Nesiope appears to be intermediate between Car- 
sidara with its deeply cleft head and Tenaphalara with its head 
not at all cleft in front. 
Key to the species. 
a 1 . Vertex smooth and uniformly rounded forward and down to genae, with 
antennae slender and well separated at base. 
ft 1 . Forewings with a longitudinal brown vitta; vertex very abruptly 
descending; insect dark colored, small, less than 3 millimeters 
long to tip of folded wings. (Philippines.) 
T. fascipennis Crawford (’17: 167). 
6’. Forewings clear, without vitta ; vertex less abruptly descending; 
insect greenish yellow, larger, at least 4 millimeters long to tip of 
folded wings. (Formosa, Philippines, and Bengal.) 
T. acutipennis Kuwayama (’08: 155). 
a J . Vertex not smooth nor uniformly rounded forward and downward to 
gense. 
b 1 . Vertex with a prominent epiphysis just behind each antennal base; 
posterior ocelli elevated; antennae approximate at base. 
c 1 . Forewings with pterostigma; third antennal segment distinctly 
thicker than succeeding segments. (Malay Peninsula.)
